18.11.2019

Many people consider repair an occupation that will certainly take a lot of time and effort. And that is why it is so important for them that, in the end, everything is done perfectly and remains so for as long as possible. Here, it is precisely in order for such desires to become a reality that fiberglass was created, which is also called the "spider line".

What is fiberglass

Probably, many have never even heard of such a building material as fiberglass, and therefore it is important to first find out what it is and what it is made of. So, this material is made from quartz or silicate sand, or rather, from glass. “It’s fragile,” you probably think. The fact is that the web is made of the finest glass threads, and as a result of their pressing, an incredibly strong, very flexible and thin canvas is obtained.
This type of material is used to reinforce the surfaces of walls, ceilings, etc. It prevents cracks on the surface, levels it, and also fixes putty or plaster. Fiberglass can be painted, primed, wallpapered, etc. It guarantees the integrity of the finish.

What are the advantages?

This type of material, like gossamer fiberglass, is gaining more and more popularity among people in the construction profession every day. But what contributes to this? What are the advantages of this material? So, here are just a few of them:

Resistant to moisture, so it can be used even in rooms with high humidity such as bathroom, kitchen and so on.
It differs in that it does not attract dust at all.
It passes air with ease.
Prevents the appearance of mold and its spread.
It is safe for humans and environmentally friendly.
Fire resistant.
Very easy to clean with a damp, clean sponge or cloth.
It is also corrosion resistant.
It does not contain substances that can cause an allergic reaction in humans.
Does not accumulate static electricity.

This material is not only very strong, reliable and inexpensive, but it is also quite easy to work with. If everything is done according to the rules, then after completing the repair, you will admire your transformed home for more than one year.

Cons of fiberglass and precautions

Anyone finishing material there are both positives and negatives. However, before deciding whether it suits you for work or not, you should weigh the pros and cons.
So, the main disadvantage is the smallest particles of fiberglass, which are inevitably formed during the work. So, for example, when cutting material and gluing it. Contact with the skin can cause irritation. To avoid this, it is necessary to wear tight gloves and overalls for work.
Experts also advise that you should never start working with fiberglass if your eyes, nose and mouth are not protected. To do this, you can use a bandage or a respirator and goggles. If you dress correctly, then in the process of work you will receive absolutely no harm to health.

Almost every surface, be it a ceiling or a wall, needs finishing. In order to make this process much easier, fiberglass is glued. When using it, the need to use a starting putty is completely eliminated.
Experts recommend using this type of finishing material without fail for those surfaces that are very often subjected to mechanical damage or there is a risk of cracks. Fiberglass is able to strengthen these surfaces, and this is possible due to the fact that it is incredibly strong and durable.
Most of all, this type of material is suitable for finishing the ceiling surface. It is very important to consider here that it can be glued to almost any wall or ceiling. For example, with this reinforcing material, surfaces such as concrete, plastered, made of drywall, and so on can be strengthened. As a result, you will get a very flat surface that can be finished at your discretion, for example, paint, putty, stick wallpaper, and so on.

Advantages of fiberglass in various fields of application

However, this type of material can be used not only to strengthen the surfaces of walls and ceilings. It can also be applied in other areas:

Fiberglass is used during roofing works. So, there are such types of it that are used as the basis for bituminous mastic.
With this material, you can protect the pipeline.
To strengthen the walls. In this case, fiberglass painting is used. It creates a reliable protective layer that will protect the surface from the appearance of cracks, both small and large enough. And he is able to prevent even cracking of the walls, the cause of which is the shrinkage of the structure.
It is also used during the manufacture of the waterproofing layer. This material is often used to process polymer sheets.
This material is often used in the manufacture drainage systems.
Designers also use fiberglass, creating real masterpieces from this material.

Also, this reinforcing material is used in order to save money. And it saves quite a lot of money. The thing is that the use of fiberglass helps to significantly increase the time between repairs.

Preparatory stage before gluing the surface with a "cobweb"

It is quite simple to glue such a finishing material as gossamer fiberglass to the desired surface. And almost anyone can do it. To do this, it will be enough to follow a few very simple rules, and then the result of your efforts will please you for more than one year.
What width or length to cut a strip of fiberglass you decide for yourself. For example, for gluing the wall surface, you can use strips equal to its height. However, when finishing the ceiling, experts recommend using strips no more than 1.5–2 m in length.
It is also very important, before sticking the "cobweb", to check where it has the front side. The thing is that the wrong side and the front side are very similar to each other. However, this material must be glued correctly. How to distinguish sides? You can find this information on the packaging or in the instructions that came with the fiberglass.
Then you should apply a special adhesive to the prepared and always dry surface of the wall or ceiling. The applied layer should be slightly larger than the width of the finishing material. The thing is that the glue absorbs and dries pretty quickly.

pasting process

After the finishing material and the surface to be glued are prepared, you can proceed to the direct finishing process. You just need to attach a strip of fiberglass to the wall and smooth it with a rag or your hands. Finally, smooth the surface with a spatula, while trying to remove all air from under the glued material.
After you make sure that the strip is firmly stuck, you will need to use a sharp knife to remove all excess. And only after that you can start applying the adhesive directly to the front side of the material. It should be completely saturated with glue, so that its color over the entire surface becomes dark from moisture.
Then you can start gluing the next strip, while it is worth considering that they overlap. It is better if possible to make the strips the same size. And professionals advise to paste over the ceiling exclusively along the room.
After the second sheet is smeared with glue, you need to, armed with a very sharp knife, cut a straight line in the place where the overlap is made. And then it will be necessary to remove all unnecessary in such a way that you end up with a perfectly flat surface.

How to paint

After the fiberglass dries, it will be possible to start finishing the surface. And most often this finishing material is painted. However, unlike sticking the web itself, coloring it is a rather difficult task that can take a lot of time and effort. And all this is because this material has a porous structure and therefore the paint will be absorbed into it very quickly, and at least it will be necessary to apply at least a couple of layers of coloring matter.
For coloring, it is best to choose a water-based paint. The fact is that it is applied much easier and more evenly. And also if you apply several layers, the surface will still remain perfectly smooth.
It is also better to prefer a paint roller brush. You simply dip it in paint and paint the surface. However, there are two things to consider here. First, the joints must be painted over very carefully, using a special "wing". And the second - the interval between applying layers should be at least 12 hours.
Also, do not forget about the precautions. When painting the painting fiberglass, do not forget to wear special clothing that will protect you from small fiberglass, which, once on an open area of \u200b\u200bthe skin, can cause quite unpleasant sensations. And it's not that easy to get rid of them.

Can fiberglass be wallpapered?

Some people don't like painted walls and opt for wallpaper instead. However, many are wondering: "Is it possible to stick wallpaper on fiberglass?".
You can stick wallpaper, but only before that the fiberglass must be puttied. And only after the putty is completely dry, you can proceed to finish the surface with wallpaper.
It is worth noting that the puttied surface can also be painted. In this case, you will reduce paint consumption several times. And another advantage of painting such a surface is that it will turn out very smooth. After all, if you apply paint directly to the fiberglass, then a kind of relief of the finishing material will appear through it.

The nuances of pasting drywall with fiberglass gossamer

It is very common that the surface of the ceiling or walls is finished with plasterboard. In order to strengthen and prevent deformation of the surface, fiberglass is also used. However, there are a couple of important nuances in pasting such a surface with this type of finishing material.

First of all, you will need to coat all the joints and the entry points of the self-tapping screws with putty. As a result, you should get an almost perfectly flat surface. Be sure to wait until the putty is completely dry.
Then you will need to coat the entire surface of the drywall with glue - this is a primer layer. And it will be possible to start finishing the surface with a “cobweb” only after the glue has completely dried. By the way, the adhesive must be used one that is specifically designed for this kind of finishing material. Further pasting is carried out according to the above scheme.

Before proceeding with the direct finishing work, you need to learn a few tips from professionals:

Usually, a material with a lower density is used for finishing the ceiling, and a material with a higher density is used for walls. This is very important to consider when choosing fiberglass, otherwise the finishing process can become very complicated.
It is also important to choose the right and very high quality glue. Don't skimp here. If you choose a low-quality or inappropriate adhesive, this can adversely affect the final result and significantly reduce the time between repairs.
When gluing the ceiling surface, it is very important to use a reliable stepladder. It should be noted that the ladder is not suitable in this case, since both hands must be absolutely free.
Fiberglass must be handled with great care. You should avoid deformation of this finishing material, as this will have a very negative effect on the final result.

Painting fiberglass gossamer is becoming more and more popular every year. And if you do not make mistakes during the finishing work, then the result of your work will delight you and your guests for many years. And to change the design, you just need to repaint the walls or ceiling in a different color or stick new beautiful wallpaper.

When carrying out finishing work, great importance is given to each material involved in the finishing. Modern trends dictate their own rules, which applies to a high level of cladding. Let's pay attention to fiberglass for painting: today this material is in great demand among professional craftsmen. Consider its features, pros and cons, methods of work and recommendations of specialists.

Peculiarities

Fiberglass is nothing more than a new generation building material that prepares the base surface for finishing. This is not cullet, as those who are unfamiliar with this material mistakenly believe. This raw material is in the form of a cobweb, which is sold in rolls 50 m long with a meter wide. It appeared on the construction market relatively recently. However, the quality of the material allows what was previously difficult to do when finishing.

The texture of fiberglass is nonwoven fabric. It consists of the finest fiberglass threads that can be pressed. Externally, fiberglass is thin and transparent. In a roll, the color of the gossamer seems to be white. When viewed, these are cobweb threads interconnected in a chaotic manner with the help of an adhesive substance based on organic resins.

The raw material for the production of fiberglass is quartz sand. The density of the preparatory material for painting can vary from 25 to 50 g/m2. It matters when choosing raw materials for different planes. Typically, for vertical surfaces, varieties with a lower density are used. For walls, you need one that is denser. With increasing density, the mass of fiberglass becomes larger.

Scope of application

The scope of this material is extensive. Its use allows you to get rid of visual irregularities and obvious defects in the base without global preparatory work. Its function is reinforcement. This is a non-decorative material: after it is fixed to the base, it is puttied, and then the surface is painted or wallpapered.

Fiberglass for painting is used on different grounds(from concrete to plastered and drywall). Due to its high quality and performance characteristics, it can be used in rooms of various purposes. The type of premises can be residential or auxiliary. Often such material is used in the preparation of the base of bedrooms, living rooms, offices, home libraries, bathrooms, hallways, corridors.

The popularity of fiberglass for painting is due to the prevention of cracks. A plane finished with paint after reinforcing with a gossamer will retain its attractive appearance for many years. You don't have to mask cracks by painting them with fresh paint.

In addition, fiberglass for painting can be used in the construction industry for:

increase the service life of metal pipes;
manufacturing floor cladding and wall panels;
waterproofing structures;
implementation of drainage devices;
preparation of mastics used in the creation of the roof.

Advantages and disadvantages

Like any building material, fiberglass has advantages and disadvantages.

Let's take a look at the benefits.

It is resistant to temperature changes. You can prepare the surface for painting in the mode from -40 to +60 degrees. This will not affect the quality of the preparation of the base.
Fiberglass is breathable and hygienic. Its use eliminates the formation of condensate and the environment for the appearance of fungus, as well as mold.
The material does not electrify, as it is antistatic. For this reason, it does not accumulate dust.
The use of the material does not have a negative impact on the health of households. This is due to the environmental friendliness of fiberglass.
It is hypoallergenic. This nuance is especially important for allergy sufferers.

Fire resistance is one of the most significant advantages. Such material is appreciated by every experienced craftsman.
The price of fiberglass is available to every buyer, which allows you to make repairs inexpensive and of high quality. It can be bought at hardware stores.
Fiberglass is highly durable. It does not deteriorate over time, so you do not have to do repairs often.
This material can be dyed. Its uniqueness is the fact that painting can be repeated.

Having studied the positive characteristics, we note the disadvantages, because they are not so harmless.

Fiberglass must be handled with extreme caution. This is due to the fact that in the process of leveling the base, small glass fragments can break off from the canvas. Sticking into the skin, they can cause significant harm to health, getting on the skin of the hands, body, sometimes in the eyes and respiratory organs. In some cases, skin itching is possible, if it gets into the eyes, you will have to consult a doctor.

Working with fiberglass requires the mandatory use of closed clothing. You need to wear gloves on your hands, a respirator and goggles on your face.

How to stick?

Consider the intricacies of using fiberglass for painting. This will allow you to get to know the material better and understand the features of its application. Initially we create optimal conditions for work. It is better to carry them out at a temperature of +18 to +25 degrees. Windows when holding preparatory work should be closed. Drafts are excluded, you need to ensure that the fiberglass does not lie under the sun.

You have to follow a little instruction.

Examine the surface of the base. If it has significant defects (potholes, large chips), set aside the fiberglass. In this case, you first need to get rid of visible flaws with a putty or plaster mixture.
After that, it is necessary to treat the base with a special primer. It is advisable to use a primer with a high penetrating power. It will level the surface structure, bind dust, fill microcracks.

After applying the primer, let it dry. In the process of drying the material, a fine crystal lattice is formed on the surface, which contributes to high adhesion. If you do not wait until the end of drying, the lattice film will be broken.
Fiberglass is not fixed with a whole panel. It must be cut into strips of such a size that it is convenient for you to work. At the same time, add small allowances to the edges (1-2 cm is enough).
Prepare glue for fiberglass. Apply it to the back of the sides and width. Spread the adhesive evenly in a thin layer (no more than 1 mm).
Start work from the corner of the plane. It can be a ceiling or a wall. After gluing the first strip, the second one is attached next to it, and so on all the rest. At the same time, a small overlap is formed, which, after the final fixation, must be cut.
So that the joints of the strips of fiberglass do not diverge, it is necessary to additionally impregnate them with glue, pressing them very carefully with a spatula. Experts emphasize the importance of this stage.

Now leave the base for 2 days to dry. Then putty it, then touch up with sandpaper to make it smooth. Before painting the surface, re-treat with a primer and allow it to dry.

How to paint?

After the surface is prepared, you can start painting. So that it does not cause trouble, it is important to choose the right coloring composition, of which there are many types today.

You can choose paint:

water emulsion;
acrylic;
silicone;
latex.

A distinctive feature of this painting is the need to apply several layers. It is impossible to apply two layers at once: it will shrink or peel off in layers for quite a short time, exposing the bases with putty. Failure to comply with the technology for the use of coloring compositions is fraught with a reduction in the life of the paint. In this case, it is unlikely that you will be able to paint such a surface several times.

In order for the application of paint to be of high quality, it is important to choose the right tool. The brush in this case is suitable only for painting joints and corners. The use of a roller would be more appropriate. It will speed up the time for painting, allow you to put a thin layer, which will reduce the consumption of the coloring composition.

Dip the roller in a container of paint, wring it out a little and roll it on a flat surface. Do not use a tool with a foam coat: the foam will crumble into pieces. Need an analogue with a pile. The movements should be in different directions: this will allow the paint to lie better and more evenly. Do not forget that the planes must be puttied and primed before painting. When painting, two or three layers of the composition can be applied.

To prepare the surface for painting with fiberglass to be of high quality, Let's turn to the recommendations of professionals in the field of construction and decoration.

After you have glued the cobweb to the surface, strengthen its fixation. To do this, dilute the glue to a liquid consistency and coat it on top. It must soak the fiberglass.
Do not ignore the start-up work, if they are really necessary. If you do not have enough experience, you can invite a specialist to help prepare the foundation.
Get the job done efficiently and without haste. The strength and reliability of the entire base will depend on how firmly you glue the fiberglass.
As an adhesive, you can use the glue that glues the glass. The composition of such mixtures contains special inclusions that prevent the formation of fungus. If in doubt about the choice, ask the seller: not every wallpaper paste is appropriate here.

When choosing dry glue, dilute it correctly. Pay attention to the harmless formulations of Bostik, Wellton, Oscar, Pufas: they have positive feedback from buyers and construction professionals.
If you need a glossy surface type, buy latex paint.

In our time, industry produces very wide range of various materials for construction and finishing works, which greatly facilitate the task of the masters, and the result obtained is much better. These materials also include the painting fiberglass cobweb, which got its name due to its external similarity with a real cobweb.

This type of fiberglass appeared on the construction market not so long ago, but is already in great demand among craftsmen who have already used it in their work at least once. The use of such material allows you to perform high-quality finishing, quickly get rid of problems that have already arisen with the surfaces of walls and ceilings, and also prevent the emergence of new ones.

What is painting fiberglass

How fiberglass is made

Many homeowners at all stages of work prefer to choose exclusively environmentally friendly materials for finishing their houses and apartments, which do not emit toxic substances at all during their operation and at the same time are not subject to rapid aging or wear. It is to this group of building materials that any kind of fiberglass can be safely attributed. Due to the absolute harmlessness, his canvases can be used in all rooms without exception, including nurseries, bedrooms and kitchens.

The fiberglass from which the canvas is formed is made from a glass melt that goes through the extrusion process, that is, it is forced through special spinning dies with holes of different diameters. The result is fibers of various thicknesses.

Fiberglass "gossamer" is made from very thin fibers. They are so small in thickness that they become visible to the naked eye only after they are combined into canvases.

Unlike fiberglass, from which it is made, the "spider web" is a non-woven material and does not have a clear, correct pattern, since its threads are arranged randomly. The manufacturing process of fiberglass is somewhat similar to the production of paper. The finest glass fibers enter the conveyor, where they are distributed on the surface of the belt, and then they go through the pressing process under high pressure with a certain temperature regime. A thin, even sheet with a smooth surface comes out from under the press. It is immediately wound into large reels, and from them it is distributed into small rolls, packed and sent to a warehouse or store.

The density of the finished compressed fiberglass "gossamer" can vary in the range from 25 to 50 g/m².

Advantages and disadvantages of fiberglass "spider line"

This auxiliary finishing material has its advantages and disadvantages, and it must be admitted that there are much more of the former. It is worth talking about them first of all.

So, dignity:

Fiberglass sheets do not accumulate static electricity.
The material is waterproof, completely unaffected by a humid environment.
Resistant to mechanical stress.
Completely inert to any chemical reagents used in the field of construction and decoration
The canvas is air and vapor permeable, so mold does not appear on the surface and under the fiberglass canvases.
Fiberglass is absolutely not subject to corrosion.
The material is hypoallergenic - harmless to people suffering from hypersensitivity to allergens or respiratory diseases.
Fiberglass is completely non-flammable, has a certain fire resistance, and is resistant to sudden changes in temperature.
Due to its structure, it perfectly reinforces and levels surfaces.
Quietly withstands several staining cycles.
Differs in durability as it is not subject to neither chemical, nor biological decomposition.
Does not attract or absorb dirt, odors and dust.
What is very important - the price of fiberglass "spider web" belongs to the category of public.

Fiberglass also has a few limitations, which you also need to know about when purchasing it for finishing work. These include the following points:

When cutting fiberglass cloths, small particles of fibers can damage the skin of the hands, therefore it is recommended to carry out this process with rubber gloves.
In addition, when cutting the material, it is desirable to protect the respiratory organs and eyes.
Work with fiberglass is best done in clothes made of dense fabric that will cover all open areas of the body. In this case, you can avoid glass splinters, which cause unpleasant itching and inflammation of the skin.

Varieties of fiberglass "spider line"

This non-woven building material is divided into three types according to its density, which can be 50, 40 and 25 g / m².

The thinnest canvas, one square meter which weighs 25 grams, is most often used for gluing on the surface of ceilings before painting them. Therefore, this type of canvas is usually called that - the ceiling "spider line". However, this type of fiberglass, due to its low density, will not be able to hide strong surface irregularities. Therefore, it is used only for relatively flat ceilings.

Canvas with medium density, weighing one square meter of 40 grams, can be called universal. It is widely used for reinforcing and leveling both ceilings, and the material is selected for pasting on surfaces that are planned to be painted in the future. Due to the high strength of this type of fiberglass, it is excellent for the lower part of walls that are particularly susceptible to mechanical damage. Glued canvases will reliably protect these areas from chips and scratches. This material is also used to strengthen dilapidated ceiling plaster - it will perfectly bind and level the surface of the ceiling. This type of fiberglass is also suitable for protecting plaster on walls and ceilings in rooms with increased vibration load.
The most durable type of "cobweb" is a material with a density of 50 g / m². It perfectly closes fairly deep bumps and cracks relatively large sizes. A layer of this fiberglass, glued to the wall, is able to withstand high mechanical stress, so it becomes the best option for reinforcing walls in workshops, garages or production shops. The cost of this material is higher than that of the first two types. And besides, when purchasing this version of the canvas, it must be borne in mind that the consumption of glue for mounting it on the surface increases significantly. In truth, there is no particular need to use this type of canvas for the walls of residential premises. For them, material with a lower density is well suited.

Features of working with fiberglass and the necessary auxiliary materials

So that the finishing of walls and ceilings has a perfect appearance, the surface under it must be prepared. Previously, this process was always carried out using putty and plaster. However, in order to do this difficult job in a worthy manner, it is necessary to have certain skills that most homeowners do not possess. Therefore, it was necessary to call a master plasterer, who performed this rather laborious work for a lot of money.

Now, small flaws in the walls are quite capable of being eliminated by the homeowner himself, pasting over the surfaces with gossamer fiberglass, since this process does not require any specific knowledge and skills.

This unique material quickly and easily prepares walls and ceilings for finishing. Moreover, it should probably be clarified that you can stick canvases on almost any surface - it can be brick, concrete, chipboard, drywall, metal or wood.

Glass wall prices

glass wall paper

Adhesive for fiberglass

For high-quality gluing of this finishing and preparatory material on the walls, you will need to purchase the “correct” glue and high-quality primer solution, since the strength of the canvases on the surfaces will depend on them. In addition, it is necessary to observe the time indicated on the packages of adhesive and primer, as well as the period between gluing the fiberglass and applying the finish.

It should immediately be clarified that it is not recommended to fix the canvases on plaster mortar, since it will not be able to saturate the structure of the material well enough, so the canvas will not be firmly fixed to the surface. Liquid putty is also not suitable as an adhesive, due to the fact that it will impregnate the fiberglass unevenly, and in those places where the material is not sufficiently saturated, the “spider web” may begin to bubble. To avoid these negative aspects, for gluing fiberglass, you need to use glue specially designed for it, which is sold in finished or dry form.

Each type of fiberglass has its own type of adhesive, so you need to follow the recommendations and use the composition that is designed for a particular material. However, on sale you can also find universal glue, which is suitable for all types of fiberglass-"cobwebs", but it must be diluted in certain proportions, since the canvas must be fully saturated with it.

Glue "Oscar" is intended for gluing glass wall papers, which have a sufficiently high density, so it is often used for gluing "gossamer" fiberglass with a density of 40 g / m².

Glue "Wellton", sold in dry form, is universal, so that it is suitable for a specific type of fiberglass, it is diluted in certain proportions indicated on the package.

Glue "Kleo" is also universal, and is used not only for gluing all types of glass sheets, but also for non-woven wallpaper. It is produced in finished and dry form.

In addition to these compositions, in the hardware store you can find others designed specifically for fiberglass. All adhesives of this type are environmentally friendly materials and are made according to a certain formula, and their components interact well with fiberglass. In addition, they include antiseptic substances that counteract the formation of colonies of fungus and mold.

Adhesive compositions designed for fiberglass and fiberglass do not leave marks or stains on the surface. Therefore, if the canvas is already glued to the surface, but it can be seen from its impregnation that the applied adhesive solution is not enough, it is quite acceptable to walk on the surface of the material with a wide brush with glue in order to achieve complete impregnation uniformity.

All technical characteristics of the adhesive can be found on the packaging, including its consumption per square meter. However, it must be remembered that the consumption of the adhesive solution will also depend on the material of the surface on which the fiberglass will be glued, as well as the quality of its pre-treatment with a primer. The better the surface is prepared, the less glue is required. To be guided by the time in work, it must be said that the period of final drying and setting of adhesives of this type, as a rule, is 48 hours.

The process of gluing painting fiberglass-"cobwebs"

To stick fiberglass on walls or ceilings, you do not need any special professional skills. It is only necessary to know the stages of work and clearly follow the presented technological instructions. Thanks to the decision made to strengthen and level the walls yourself, you can save a decent amount, so repair work are quite expensive.

Illustration	Brief description of the operation to be performed
	The first step is to remove the old decorative coating from the walls, if it is wallpaper or plaster that has begun to spontaneously separate from the wall.
	The cleaned wall should be carefully examined. If wide and deep cracks are found, they must be repaired, as they will contribute to the delamination of the material from the wall. To do this, the crack expands, impregnated with a primer deep penetration and dried, and then filled with sealant or cement-adhesive mortar. The surface of the filled cracks must be leveled as much as possible. If protrusions of a rather large size are found on the wall or ceiling, then they must be knocked down with a hammer or cut off with a grinder with a circle over the stone.
	The next step is to clean the surfaces of dust and dirt - this process can be done with a brush or a vacuum cleaner can be used for it. There should be no large particles of cement or other solid matter left on the surface, like crumbs of plaster or putty.
	Next, the surfaces must be primed with a deep penetration solution. Such solutions, applied in two or sometimes three layers, penetrate the wall or ceiling to a considerable depth, closing the pores in the material structure and contributing to additional waterproofing. In addition, the primer creates a film on the surface, which will create high adhesion for the materials applied to it, in this case, the adhesive solution. This type of primer is also able to bind and strengthen weak layers of plaster. The primer should be absorbed into the structure of the surfaces and dry well.
	If serious irregularities are found on the wall, then after the primer has dried, you should try to level them with ready-made putty, which is applied with a wide spatula. However, this process is carried out only as a last resort - usually only fiberglass is enough for high-quality alignment. If the putty was nevertheless applied, then after it dries, the surface must be covered with another layer of primer.
	When the walls are dry from the primer, you can start gluing the fiberglass sheets. Glue is applied to the section of the wall on which the material is planned to be glued. If the entire wall is pasted over with a “cobweb”, then its installation starts from the corner of the room.
	A canvas is applied to the area of the wall surface smeared with glue, and it can be of any size, since the fiberglass fits well, and the overlaps, due to the thinness of the material, become almost invisible (however, you can get rid of overlaps altogether - more on that below). The canvas is pressed in the upper part, and then smoothed out according to the “herringbone” principle with a special plastic wallpaper spatula. That is, first, with a spatula, they are carried out with a slight pressure in the center of the sheet, and then, starting from the top, from the middle, they begin to drive the excess glue down and to the sides, as if “drawing” the branches of the Christmas tree. The adhesive composition is absorbed into the fiberglass quickly enough, so there will not be much excess, and it will not take long to drive them out from under the canvas. The material will immediately show how well it is impregnated with the adhesive, but in order to prevent even the slightest possibility of its peeling, it is recommended to walk on top of it with a roller, also moistened with glue.
	If you need to level the ceiling, it is best to carry out this process with an assistant. If you have to do this work alone, then it will be more convenient to stick the fiberglass in small pieces. To do this, a layer of glue is also applied to the surface, and then, starting from the wall, a sheet of leveling material is glued.
	After sticking the first sheet of material, the adjacent section of the wall is smeared. The next sheet is applied to it, and it can be glued end-to-end or overlapped by about 40 mm. If the second option is wiped off, then immediately after gluing the second canvas, 20 mm is measured from its edge, which finds on the first sheet. Then, a metal ruler or a flat wooden rail is applied vertically to the points found, parallel to the edge of the canvas, and a sharp knife is drawn along it, cutting through both sheets. After that, the cut off parts of the paintings are removed, and the edges are pressed against the wall with a spatula. Thus, a perfectly even joint of two sheets is obtained, which must be pressed with a roller dipped in glue.
	If the canvas turned out to be longer than necessary in length, then it is best to cut it off immediately. To make the cut even, the fiberglass is strongly pressed against the wall with a wide spatula, and then drawn, as if along a ruler, along it with a sharp knife. If necessary, the edges of the canvas are additionally glued. You can proceed to further work on finishing the walls only after the glue has completely dried - this time is indicated by the manufacturer on the package.

When gluing paintings on walls or ceilings, as well as during their drying, there should be no drafts in the room. It is also impossible to turn on electric heaters, trying to speed up the drying of the glue, as this can lead to delamination of the material from the wall.

When reinforcing walls or ceilings with fiberglass, it is necessary to make preliminary surface preparation, which is necessary for this material. Since such a sheathed surface has sheet joints that are somewhat recessed relative to the general level, they must be brought to the same plane using putty. Before applying it, the joints are recommended to be primed and glued with a mesh or special paper tape. The primer will increase the adhesion of materials, and the putty will be well fixed on the surface, and the reinforcement will prevent the appearance of cracks in case of possible wall movement (shrinkage, vibration impact, seismic factor, etc.)

Basic rules for preparing drywall walls for further finishing

Montage drywall sheets on the walls, preparation for finishing does not end - there is another rather complicated and time-consuming stage ahead. - read in a special publication of our portal.

After the putty has dried in the drywall joints, the entire surface of the wall is covered with a primer, which must also dry, forming a film on the surface.

After that, you can begin the process of reinforcing drywall with a "spider line". Its gluing occurs in the same way as on a concrete or plastered wall.

Decorative wall covering with fiberglass

Fiberglass is painted or coated with other materials only after it has completely dried. Walls covered with masking fiberglass can be painted without additional coating, or after applying a leveling layer of putty on them.

If the paint is applied directly to the "cobweb", the structural pattern of the canvases will be visible through its layer. In addition, you need to know that a lot of paint will be required, since even the material impregnated with glue absorbs the paint composition well.

If it is planned to obtain absolutely smooth walls, which are necessary, for example, for sticking thin paper wallpapers, then a leveling layer of putty is applied to the fiberglass.

For work, finishing putty is used, which is closed with water and kneaded in strict accordance with the instructions supplied by the manufacturer, and applied to the surface with a wide spatula, starting from the corners of the room. If in order to stick fiberglass does not need special skills, then to perfect smoothness it requires some skill and experience.

For some novice masters, this process is obtained immediately, while others cannot cope with this work. To test your abilities, it is recommended to cook a small amount of putty mixture and try to apply it on a small, not very noticeable area of \u200b\u200bthe wall. If everything works out, then it will be possible to save on the implementation of this stage of work by doing it yourself.

Putty should be applied in a thin layer of 1.5 ÷ 2 mm, trying not to leave recesses and stripes on the surface from the edges and corners of the spatula.

After applying the putty, it is necessary to wait for it to dry, after which the surfaces are treated with sandpaper to perfect smoothness. This work can be done manually using a construction grater, or you can use a grinder (for example, eccentric or vibrating) for leveling, on which abrasive paper is fixed.

If putty is applied in two or three layers, then each of them should dry well before applying the next.

The advantage of painting non-putty fiberglass is that the unevenness of the paint applied to it will be less noticeable, since the structure of the material is able to hide them due to its relief. However, due to the fact that fiberglass absorbs paint well, it will have to be applied in at least two layers, the second of which is applied 12 hours after the first.

It is more difficult to apply paint evenly on a perfectly smooth surface, since all color differences will be noticeable on it. Therefore, in order for the color to be uniform, it is sometimes necessary to apply the coloring composition in two or even three layers.

For painting fiberglass or putty surfaces of residential premises, it is recommended to use water-based paint, applying it with a roller with a fur nozzle, and carefully and accurately tinting hard-to-reach areas of the wall and ceiling with a soft brush.

Some masters, in order to bypass the stage of puttying the fiberglass, after gluing it and drying it, apply several layers of thickly mixed glue to the reinforced surface, each of which is also dried. The adhesive layer, filling the structural pattern of the surface, makes it smoother, but not perfectly even. The adhesive layer also significantly reduces the consumption of the coloring composition.

How to choose fiberglass?

To purchase high-quality material that will meet all the above characteristics, you need to choose products from well-known manufacturers.

On the Russian market building materials, the products of manufacturers from Holland - "Spektrum", Finland - "Wellton", and Sweden - "Oscar" and "Samtex" gained popularity. From domestic manufacturers, the technology of manufacturing fiberglass, in full compliance with international standards, was well mastered by the X Glass company. It should be noted that almost all companies producing fiberglass, except for them, produce fiberglass wallpaper, as well as adhesive compositions for them - these products come under the general brand of the company. It is advisable to use canvas and glue of the same brand - they are fully adapted to each other.

In conclusion, I would like to recall that the painting fiberglass-"cobweb" is primarily intended for reinforcing the walls and ceilings of the premises and protecting them from the expansion of cracks that have appeared. small size, as well as from the emergence of new ones. The second function that this material is designed to perform is the alignment of surfaces. However, many homeowners also prefer to preserve the fiberglass structure without covering it with putty, and using it as a decorative material. Thus, the "web" acquired a third function.

One cannot but agree that this multifunctional material helps to solve many problems and save money allocated for interior decoration. Therefore, for many owners, it can be a real salvation during any repair - both cosmetic and major.

And at the end of the publication, traditionally - a video on the topic. This time, a professional finisher will share his experience in gluing fiberglass "spider line".

Video: How to stick fiberglass "spider web" correctly

To save energy during the next repair on leveling the surface of the ceiling or walls with numerous minor flaws, you can simply use fiberglass, the use of which is becoming more and more relevant when finishing and strengthening internal surfaces.

Painting fiberglass is a modern environmentally friendly material that is created from mineral and organic resins. This is a continuous non-woven cloth without a pronounced pattern, which has a huge tensile strength. Fiberglass for painting has fibers that are not intertwined, like those of glass wall paper, but simply glued randomly, representing a uniform sheet of fiberglass strands arranged randomly.

Fiberglass, the price of which is quite moderate, is often called fiberglass. And among the people, such a building material has acquired the name "spider line", thanks to a pleasant and soft texture.

This building material is divided into several classes, according to its density (thickness). Now you can buy fiberglass with a density of 25 to 65 g / m 2. Its density directly affects the cost: the thicker the canvas, the more expensive it is. Experts recommend choosing fiberglass for the ceiling with a density of about 25 g / m 2 to guarantee a reliable and lightweight coating. But a material with a high density index is able to withstand more serious mechanical loads, restraining the appearance of cracks.

It is wrong to assume that gossamer and cullet are one and the same material. Glass fiber is a decorative roll coating made from fiberglass by weaving. And fiberglass is a special material for wall covering, created by pressing fiberglass threads. Fiberglass painting has a thinner, smoother surface than glass. The cobweb has no pattern, which makes it possible to color an infinite number of times. Fiberglass, the price of which is at least 2 times less than the cost of glass wallpaper, is 100% environmentally friendly material.

Among the repair and finishing materials deserved respect worthy of repair interlining, which does not require puttying, with the possibility of applying almost any paint.

Fiberglass gossamer: price, properties, benefits

If you buy fiberglass building material, then the repairman is provided with an environmentally friendly finishing and reinforcing fabric that is approved for use in residential premises. The products of such manufacturers as Wellton (Finland), Spectrum (Holland, China), Оscar (Russia), Samtex (Sweden) and others are very popular.

Ordinary fiberglass painting, the price of which ranges from 500 rubles. up to 800 rubles for 1 roll (25 m 2 or 50 m 2), depending on the manufacturer, most often has a width of 1 m.

has a high fire safety
possesses thermo-, water-, acid resistance
hypoallergenic, durable
excellent leveling and finishing
allows you to carry out finishing work in rooms with high traffic of people, due to the high density

Modern oscar fiberglass made in Russia-Sweden is a fairly wear-resistant strong material. It is almost impossible to damage the glued panel, unless you cut it with some sharp object. Oscar fiberglass is a relatively inexpensive material that can be painted with any type of paint at a much lower cost than when painting only a puttied surface. Fiberglass VVG, Oscar, Velton can be re-painted.

Fiberglass painting gossamer has the following advantages:

does not burn
not subject to corrosion
moisture resistant
"breathes", passing water vapor
does not cause allergic manifestations
easy to clean
prevents the growth of mold
does not accumulate static electricity
does not attract dust
does not emit substances harmful to human health, etc.

Important features of the use of fiberglass include the fact that small particles of vitreous threads can seriously injure hands when cutting. It is strictly forbidden to work with painting fiberglass without gloves. It is recommended to use eye and respiratory protection, as well as tight rubberized overalls to prevent the smallest glass "shards" from getting on the skin, which can cause itching.

Fiberglass: application in repair

Smooth fiberglass painting gossamer is recommended for use in plastered or plasterboard houses, effectively replacing the finishing putty. The material is widely used on surfaces that are prone to cracking, to prevent the appearance of small cracks, flaws in the finish.

Fiberglass gossamer additionally reinforces the surface of the wall or ceiling, making the base more durable. It is rational to use fiberglass when leveling ceiling slabs: fiberglass is glued to the ceiling when it is not possible to sew it up with drywall.

When there is no desire to paste over the room with embossed wallpaper, you can buy fiberglass, having previously prepared the surface for painting. In this case, painting fiberglass serves as an additional means to strengthen the ceiling and walls. It is glued with a special ready-made glue, then it is necessarily primed, puttied, and then painted.

Painting fiberglass can not be puttied, but only primed with a liquid solution of glue, allowed to dry, painted. But in this case, you will need not only much more paint, but also time, because you will have to paint at least 3 times, but you still won’t be able to evenly paint over with a roller.

Durable gossamer fiberglass allows you to protect the walls from the appearance of network-like or single cracks on the painted surface, which can appear from defects that have appeared on drywall, plaster or putty due to shrinkage or heating of the building. Often, cracks appear on the painted base, which occurs only if fiberglass is not used, the price of which is much less than the cost of a new repair.

Features of the structure, elasticity of the fibers of the glass painting canvas allow it to withstand destructive changes, preventing their occurrence on the surface of the ceiling or wall. Fiberglass, the use of which depends on its main property - surface reinforcement, is used, regardless of gluing the "sickle" at the joints of drywall sheets. Often, drywall in stores, on bases is stored in improper conditions, gaining unnecessary moisture during storage, which begins to evaporate after installation, and the structure cracks.

Fiberglass: how and with what to glue and paint

The process of gluing the panel on the wall begins with its preparation: the surface is cleaned of dust and dirt, large cracks are processed. The answer to the question: "How to glue fiberglass?" simple enough. Sticking a "cobweb" is much easier than any wallpaper, because the glue needs to be applied only to the wall, and not to the canvas. Moreover, it is desirable to use a special glue for fiberglass, for example, from Wellton.

Most often, the canvases are applied end-to-end, neatly aligned with a spatula. How to glue fiberglass, which, due to improper storage or rough transportation received damage to the edges? Such a canvas can be safely glued with an overlap, as well as when working on curved, broken surfaces, where it is necessary to apply the coating in parts.

So, there is fiberglass, how to glue it correctly? The technology of gluing or mounting fiberglass is quite simple:

rough puttying of the surface is carried out using the material of the brand "start"
the ceiling is treated with a deep impregnation primer such as Ceresit, Condor
specialized glue is applied to the walls (ceiling) with a roller or spatula
the first sheet is glued from the corner of the ceiling, it should be less than the surface area, slightly smoothed along the edge of the “joining” to improve the quality of the reinforcing material
glue is applied to the base with a slight approach to the piece that has just been glued
the next part of the fiberglass is applied, slightly smoothed with a spatula in the area of \u200b\u200b"overlapping" the two canvases
immediately a cut is made in two canvases with an ordinary clerical knife
the cut off parts of the lower and upper canvas are removed, both parts are simultaneously smoothed with a spatula at the junction
then the surface is primed with diluted glue (special primer)
after complete drying, the walls (ceilings) are puttied with finishing putties, cleaned with an N150 abrasive mesh, primed with the same primer
now you can decorate the surface as you wish: paint acrylic paints etc.

While the fiberglass is being glued, it is important not to miss a single millimeter of area so that the entire canvas is evenly saturated with the adhesive. Using a spatula, excess glue is removed. It should be remembered that it is better to apply the glue not too thinly, the most best option about 1 mm.

Important: it is necessary to avoid drafts until the material is completely dry.

Properly glued and successfully painted glass fiber canvas creates the appearance of perfectly even walls. Such material can be used as a basis for decorative plaster. Subject to the technology of working with the cloth, the canvas will reliably protect the ceiling or walls from cracking. The remains of glass painting material are disposed of together with construction waste.

Fiberglass: versatility of application

It is interesting to use fiberglass as an intermediate layer to ensure high-quality gluing of polymer or vulcanized rubber roofing materials with help bituminous mastics to the work surface.

In order for such a coating to have good adhesion of the waterproofing sheet and building structures, the rubber or polymer sheet is duplicated on one side with fiberglass.

Painting fiberglass is also used in the manufacture of waterproofing materials, in the production of floor and wall panels made of PVC materials. The canvas is used as an excellent anti-corrosion protection for pipelines, in the construction of drainage systems, etc.

The multi-faceted fiberglass gossamer ideally solves many of the problems that arise during do-it-yourself home renovations associated with uneven walls and their minor defects. Its use will significantly increase the interval between repairs in the house, which will positively affect the thickness of the wallet. Good luck with your repair!

The development of building technologies has contributed to the introduction of innovative solutions for the creation of new multifunctional building materials that simplify work during the construction and decoration of buildings for various purposes.

A striking representative of modern building materials with a wide range of functions and a variety of applications is fiberglass, made from ultra-thin glass fibers with a diameter of 10-18 microns.

He owes his popularity availability of raw materials and environmental cleanliness its components - quartz sand, clay, limestone rocks and glass scrap in the form of cullet.

The use of recycled glass raw materials allows us to successfully solve the issues of maintaining the cleanliness at the proper level. environment and obtaining relatively cheap building materials such as fiberglass or glass.

The basic raw material for the manufacture of glass fabrics are glass elementary fibers-filaments obtained in the process of pulling molten glass mass through platinum spinnerets.

The production of fiberglass is based on the same principle, which you can read about.

Components are used to prepare the glass melt natural origin(quartz sand, clay and limestone) and glass recycling based on cullet.

The addition of cullet to a mixture of raw materials, called charge, significantly saves material and energy resources used for the production of glass fiber.

Due to the processing of one ton of cullet, more than one ton of the main natural raw materials is saved, including the following materials:

quartz sand - about 650 kg;
soda ash - about 185 kg;
limestone - almost 200 kg.

For every 10% added mass of cullet consumption of heat and electricity is reduced by 3%, since the melting of a charge composed entirely of natural components requires a higher temperature than a charge containing cullet.

With the introduction of 40% cullet, energy savings will be 12%, which significantly affects production efficiency.

In total, about 3 million tons of fiberglass are produced in the world.

Leading glass fiber manufacturers pay special attention to glass recycling.

The presence of cullet among the components of the produced fiberglass reduces the amount of pollutants, removed to the atmosphere, allowing the manufacturer to save on emission treatment equipment.

You can read about other ways to recycle cullet and their benefits.

Differences from glass fiber

The technology for making canvas from glass fibers is fundamentally different from the production of glass fabrics:

fiberglass is obtained by pressing fiberglass, randomly located under the press;
fiberglass fabrics are woven on textile weaving equipment.

After pressing the fiberglass, fiberglass is formed - thin smooth material without a pronounced pattern resembling sheets of paper.

From glass raw materials, fiberglass "inherited" its main properties - chemical inertness, resistance to open fire and other qualities that made it one of the most popular building and industrial materials.

In accordance with the production technology, fiberglass differs from glass fiber in terms of surface density and functional purpose:

fiberglass density does not exceed 50-65 g / sq.m, which allows it to be confidently used to cover ceilings;
the density of glass fiber exceeds that of fiberglass and is 150-225 g / sq.m;
fiberglass is a finishing material for covering walls and ceilings, involving subsequent finishing painting; thanks to the smooth surface, fiberglass allows multiple repainting without compromising the quality of the coating;
cullet is a finishing decorative coating that does not require mandatory painting.

With repeated repainting, the quality of the surface of glass fiber deteriorates significantly.

This is precisely what very important difference between them and the fiberglass.

Thus, it is up to you to decide what is better to use for painting: fiberglass or wallpaper.

If you plan to repaint the coating several times, the choice is obvious.

You can read more about glass wallpapers and their differences from fiberglass in the article.

Applications

In Russia, more than 200 million m² of fiberglass is used annually. In construction and industry, it is used in combination with other materials that are selected according to purpose and technical requirements to the final product/object.

So, what is fiberglass used for:

Production waterproofing coatings, in which fiberglass cloths serve as the basis for applying bituminous impregnating compounds (roofing). In construction practice, bituminous coatings are used in the form of rolled roofing materials and soft bituminous tiles.
The production of linoleum, in which fiberglass is used as a supporting frame that prevents shrinkage of linoleum.
Manufacturing, in which fiberglass serves as a reinforcing material for impregnation with binder polymer compounds during the subsequent shaping of the product (boats, containers, etc.).
Construction, repair and finishing works in which fiberglass is used for:

creation of protective reinforced surfaces of walls and ceilings;
formation of the finishing coating of walls and ceilings, subject to subsequent decorative painting;
creation of a sound-insulating substrate in "floating floor" structures to reduce the level of impact noise.

The soundproofing canvas is a multilayer rolled material with a one-sided bitumen-polymer coating, which is used as elastic soundproofing substrate under cement-sand reinforced screed.

Varieties by density

The technology for the production of fiberglass is based on the pressing of chopped or staple fiberglass, the result of which is sufficient soft and flexible nonwoven fabric.

Depending on the dimensions of the pressed elementary fibers-filaments (diameter and linear length of the segments) and the method of joining the fiberglass filaments in the panel, the surface density of the fiberglass varies from 25 to 450 g/sq. m with a panel thickness of 0.5 to 4 mm.

In accordance with the absolute value of the density of fiberglass, its operational purpose changes. With an increase in this technical characteristic, the indicators of its mechanical strength increase proportionally.

Currently three groups are marked fiberglass, united by density indicators, a set of functions and scope.

25 to 65 g/m²

They are produced using wet pressing technology, identical to the process of making paper smooth sheets.

Canvases of this group are used for finishing walls and ceilings, for which they received the name painting glass canvases.

A more popular name for the materials of this extensive group is “spider web”, which they received because of the translucent texture, reminiscent of an openwork woven cobweb.

For writing paper for copiers and printers, the standard of surface density within 80 g/sq. m. The density of the "web" one and a half to two times lower than a sheet of paper.

For the manufacture of "cobwebs" use glass fibers with a diameter of 10-11 microns with a length of the constituent glass fibers of 6-10 mm (data on masking fiberglass brand Spectrum SN 30 were used).

For strengthening the structure during pressing modified polyvinyl alcohol is used.

Another name for painting fiberglass - glass fleece - was assigned to it because of its identity with painting non-woven fabric, which is a non-woven paper-like finishing material based on glued cellulose fibers.

60 to 200 g/m²

These materials differ from the paint "cobweb" by pressing technology:

fiberglass is combined using synthetic resinous components;
the fibers are unevenly distributed over the volume, forming a rough, rough, uneven surface, while the fiberglass has a smooth and soft surface, and the fibers are evenly distributed, without clots and seals.

Fiberglass of this group has found its application as waterproofing materials, therefore they are often called roofing and bituminous fiberglass (depending on the type of binder and its quantity).

Outwardly, they no longer resemble a weightless "cobweb", but look like a dense, opaque canvas with the following characteristics:

glass fiber diameter - from 13 to 18 microns;
fiber length - 12-18 mm;
panel thickness -0.5-1.0 mm.

It should be noted that roofing fiberglass perfectly absorbs moisture and .

The use of roofing fiberglass is regulated by GOST 30547-97 “Roofing and waterproofing roll materials. General technical conditions".

The following brands are most popular:

Fiberglass brand TechnoNIKOL, produced according to TU 5952-001-13344965-2004. The density of the material is 100 g / sq.m, the thickness of the panel is 0.8 mm. The glass fiber used has a diameter of 13-16 µm and a fiber length of 12-18 mm.
Fiberglass brand VVG, produced in accordance with TU-21-5328981-16-96 with a width of 200, 400, 1000 and 1200 mm. Max Diameter fiberglass is 18 microns. Panel thickness - 0.5 mm, surface density - from 60 to 200 g/sq.m, depending on the type of binder.
Reinforced fiberglass of the XSA brand, produced according to TU 5952-012-04001485-97. From competing analogues (scrims TechnoNIKOL and VVG) reinforced fiberglass characterized by increased mechanical strength due to reinforcement with glass fiber in the longitudinal direction along the entire length of the material with a step of 30 mm. The density of the reinforced fiberglass varies from 45 g/sq.m (for the XSA-45 brand) to 115 g/sq.m. m (mark HSA-115). According to HCA experts far exceeds traditional VVG according to physical and technical parameters and is a more suitable basis for the application of modern bitumen-polymer coatings.

Fiberglass is also used to create multilayer bituminous roll materials, of which the most popular glass isol TU 5774-004-00289973-96 grades K-3.5 (HKP) and K-4.0 (HKP).

The surface density of such coatings is 3500-4000 g/sq. m, since it takes into account the weight of the bituminous mixture and other components of the glass isol.

In the practice of marketing bituminous roofing coatings based on fiberglass, such materials incorrectly called bituminous fiberglass.

450 g/m²

This type of fiberglass is called pierced.

They are produced by fastening knitting and stitching weave several layers of glass fibers with a diameter of 6-13 microns.

The firmware is carried out with glass threads. The formation of the material proceeds without the use of binders.

The scope of pierced fiberglass is thermal insulation of building structures and pipeline systems of heating mains.

Accepted name and designation heat-insulating pierced fiberglass PSH-T. The thickness of the PSH-T panel is 2.0-4.0 mm.

Decorative interior trim

For interior finishing work in residential and public buildings- children's and medical institutions, offices, hotels - painting fiberglass - "cobweb" is especially in demand.

The "web" is easily torn until it is pasted on any surface.

However after adhesive impregnation in the process of sticking to a wall or ceiling, its strength is comparable to the strength of steel, which allows fiberglass to act as a reinforcing material.

This feature provides the web with the following functionality:

reinforcement of walls and ceilings in order to preventing cracking processes and the appearance of microcracks;
increase in surface strength, since fiberglass, even after applying a paint and varnish coating, retains mobility and in the process of many years of shrinkage of the walls of new buildings to a sufficient extent withstand shrinkage loads to prevent microcracks from growing;
masking of already existing microcracks and hiding defective areas surfaces;
alignment surfaces of walls and ceilings for painting;
giving specific decorative texture wall and ceiling covering for artistic interior decoration and painting.

Benefits of using in finishing works

The main advantages of the "cobweb" include the following factors:

Increased fire safety premises, pasted over with painting fiberglass.
Resistance to open flame and high temperatures in the event of a fire in the room - fiberglass can withstand up to 1300 without destruction and does not emit toxic substances.
Valuable ecological qualities- coatings from the "cobweb" do not emit harmful substances and cannot provoke allergic manifestations.
High chemical inertness in relation to corrosion, influence of acids and alkalis.
Absence conditions for education fungus and mold.
Antistatic coatings, as a result of which static electricity and dust do not accumulate on the finished walls and ceiling.
Fiberglass is not susceptible to impact dampness and condensation.
"Spider web" does not lose its operational properties with sudden temperature changes.
Good ones strength properties that preserve the integrity wall covering in houses and apartments with pets;
Possibility of multiple repainting without loss of decorative qualities.
A wall pasted over with a "cobweb" will not impede the movement of water vapor and air, positively affecting the microclimate of the dwelling.

Summarizing the list of advantages of painting fiberglass as a finishing material, it should be noted that it is fully adapted to modern special requirements for materials for interior decoration of residential and public buildings.

We note the following circumstances that are at the forefront of the requirements for interior decoration:

hygiene coating, implying the possibility of its constant wiping, washing and disinfection;
antistatic fiberglass material;
bactericidal properties, allowing the use of "cobwebs" in the wards of clinics, in kindergartens, in pools and baths;
moisture resistance;
good acoustic properties in room.

Application Disadvantages

The disadvantages of the "cobweb" include the following points:

fiberglass painting canvas by structure is soft and pliable, which makes it very difficult to fix it in one position when pasting walls or ceilings, so it is practically impossible to handle the material alone;
the difficulty of dismantling the already pasted "cobweb";
canvases "cobwebs" prevent the propagation of small cracks, however, by simply applying it to the wall, it is not able to "cope" with the elimination of large defects; when they are eliminated, it is necessary to carry out a preliminary preparation of the walls and putty, only then glue the fiberglass;
painting fiberglass without putty 2-5 times increases paint consumption compared with the coloring of the pre-putty "spider line";
the need to work in protective rubberized overalls and protect the organs of vision and breathing in the process of cutting and gluing fiberglass.

Fiberglass consists of thin glass fibers, which, when cutting the canvas break down. Glass microshards become hazardous to the skin, vision and breath.

Types of painting fiberglass

In interior decoration work, the "spider line" is used as a reinforcing layer, so front side painting fiberglass has a smooth surface, while the wrong side has a fleecy and rough surface to improve adhesion to a wall or ceiling.

Depending on the value of the surface density of the "cobweb" material divided into three groups:

Vitrulan's VPP 200 series pigmented fiberglass should also be included in the category of painting thick glass mats. It can no longer be called a “spider line”, since the density of fiberglass is 200 g / sq. m.

On the front surface of the material, a layer of primer paint is pre-applied in a factory way, and on the fiberglass model Vitrulan VPP 200 Aqua, in addition to the “primer” layer, a layer of adhesive base is applied on the wrong side of the panel.

Due to the presence of an adhesive composition, Vitrulan VPP 200 Aqua can be classified as a self-adhesive wall covering, because when it is glued just wet enough wall without additional application of another adhesive.

The high density of the canvas allows you to reliably hide wall defects, and pre-applied paint ensure even distribution for finishing decorative painting.

One coat of glossy paint is enough to make the painted canvas fit perfectly into the interior of any style.

Sticker work algorithm

Speaking about how to use painting fiberglass for walls or ceilings, it is necessary to describe the following steps.

Stage 1 - preparation wall and ceiling surfaces (hereinafter referred to as the base), which includes a number of mandatory operations:

removal from the base of the remnants of the old finish;
cleaning from dust and dirt deposits;
sealing large cracks and recesses, leveling protrusions;
priming to ensure maximum adhesion of the adhesive to the base.

Stage 2 - cutting pieces fiberglass for gluing, including the following operations:

cut the "cobwebs" in accordance with previously made measurements and estimated calculations;
cutting off the cut panels from the roll.

It is customary to cut pieces of material in such sizes that it would be convenient to work with.

Stage 3 - kneading glue. Many craftsmen use their own adhesives, believing that it is much cheaper.

Of the "proprietary" adhesives for fiberglass, practitioners distinguish brands:

Oscar;
wellton;
nortex.

Stage 4 - directly gluing fiberglass. When pasting rooms to create modern interior the method of the so-called "double cut" is used, which makes it possible to obtain canvases glued end-to-end:

first, two sheets of material are overlapped, as shown in the photo;
thickenings at the place of overlap are cut off with a knife along the entire length and removed.

Leading manufacturers

The Russian market of foreign fiberglass manufacturers is dominated by companies that produce not only painting glass fleece, but also a wide range of other fiberglass products - glass wall paper, fiberglass, roofing and waterproofing materials.

Among them, the undeniable leadership belongs to the following brands:

Vitrulan (Germany) - produces fiberglass in a wide range of cloth density, ranging from 25 to 300 g/sq.m. For truly "German" quality, buyers of Vitrulan products have to pay high prices - the cheapest "webs" cost at least 2000 rubles / roll.
Wellton (Sweden) - workshops that produce masking fiberglass are located in Finland and Germany. Velton products are slightly cheaper than their counterpart Vitrulan (1500 rubles / roll), but in some cases from users there were complaints due to shedding of the coating.
Oscar (China) is a Chinese manufacturer that is in line with Wellton products, as it produces them under its Oscar brand. The cost of the "web" ranges from 1000 rubles / roll.
Nortex manufactures fiberglass in the Czech Republic and China. On the Russian market, Nortex material is sold at a price of 610-630 rubles per roll.
TechnoNIKOL is a domestic manufacturer widely represented in the supply of fiberglass high strength for industrial premises and roof insulation. Roofing fiberglass in a roll 9 meters long costs 669 rubles.
X-Glass- Russian company, producing fiberglass at the European level of quality. While the range of fiberglass is not wide, but it attracts users its affordability. Depending on the density, one roll of a standard size costs from 516 rubles. (density 25 g / sq.m) up to 646 rubles. for material with a density of 50 g/sq.m.

Which is better to choose?

When choosing a painting canvas for use in finishing work, they are guided the following circumstances:

its purpose (for painting, under paper wallpaper or wall panels, etc.);
type of surface - wall, ceiling or floors;
the degree of dilapidation of the surface;
type of defects to be sealed (cracks, cavities, bulges);
the base material on which the fiberglass will be glued - concrete, brick, wood, etc.;

Conclusion

The use of fiberglass in repair and finishing works effectively solves the problems of elimination of minor defects and irregularities walls, successfully replacing the finishing putty and hardening the surface.

As you can see, the price for a roll of gossamer fiberglass and other types of this material for painting or wallpaper varies depending on the density, which is determined on the basis of grams per m².

The growing popularity of fiberglass materials and their availability in the domestic market creates additional incentives for rational use of natural resources and glass recycled materials for the manufacture of such popular finishing coatings as gossamer or cullet.

Now you know more about why fiberglass is needed, what density of material is better to choose for a wall or ceiling for painting, how it differs from glass fiber, how much it costs.
