Stone houses have been popular since ancient times because they are reliable and durable. Several centuries later, we can observe buildings made of this natural material, which are still well preserved. Finishing the house today natural stone everything is also in demand and dictates new style conditions. Finishing can be done by combining several types natural materials. The result is a reliable, stylish shelter that can withstand the influence of the external environment and negative mechanical impact. There is no longer such a need to completely build a house of stone. Natural stone is ideal for finishing a house and it takes much less material than completely erecting walls. The range of stone is quite large, everyone can choose the material according to their taste both in color and in texture. Advantages of cladding If we compare stone cladding with other materials, then against their background, of course, it wins not only in terms of strength and durability, but also in appearance. It is also worth noting that the natural material is environmentally friendly and has a positive effect on health ...

How to plaster Penoplex? List of tricks and actions

High-quality and fast installation of systems:

After performing insulation work, the question often arises of how to plaster Penoplex. For those who are not in the know: this is the name of the material, which is extruded polystyrene foam and differs from the usual polystyrene almost only in increased rigidity. The remaining characteristics of the material are almost the same: it does not rot, does not absorb water, has low thermal conductivity and is used mainly for external thermal insulation. However, from a technological point of view internal insulation generally illiterate and permissible only in the most extreme cases, which does not prevent people from often warming themselves from the inside.

By the way, the assurances of advertisers and sellers that the use of "Penoplex" is more effective than foam plastic are somewhat dishonest: their thermal insulation characteristics are almost the same, the difference can be safely attributed to the area of ​​​​permissible errors. The material only benefits from less brittleness.

How to plaster "Penoplex" and what to use at the same time, depends, first of all, on the location of the heat insulator: from the outside or from the inside.

Why plaster over insulation?

The need for the process is explained by the similarity of the characteristics of "Penoplex" and foam.

• Despite the higher rigidity, it remains insufficient. Without strengthening the surface, an accidental dent will give a whole web of cracks that will provoke peeling of the insulation and weakening its thermal insulation properties.
• Polystyrene when heated (even without burning) begins to release styrene - volatile and poisonous. The plaster protects the "Penoplex" from overheating and the accompanying decomposition.
• The material is not very resistant to weather influences, like its analogue - polystyrene. Changes in temperature and humidity, coupled with exposure to ultraviolet radiation, can disable it in one season.
• The seams between the sheets of insulation may well become cold bridges, and only solid plaster can eliminate this possibility.
• As for flammability: polystyrene foam itself ignites with ease. However, during the production of Penoplex, flame retardants are added to it, as a result of which the material becomes self-extinguishing. However, flame retardants do not protect against the release of toxins.

What will be needed?

In any case, both for external and internal insulation, during plastering, a reinforcing paint mesh will be required. For external work, a variety resistant to alkalis is purchased; when carrying out internal work, this is not a prerequisite.

From the inside, "Penoplex" can be safely plastered with gypsum compounds. Most often, for these purposes, mixtures produced by Knauf are used - Rotband plaster or Fugenfueller universal putty. The adhesive qualities of these compounds are usually sufficient for reliable adhesion to the surface. However, at the height of human growth, it is better to prime the walls with Betonokontakt from Tikkurila or Ceresit CT 19: increased mechanical loads are likely here.

Gypsum is not used outside - it is hygroscopic and not waterproof. However, the usual cement mortars You can’t work on Penoplex: cement corrodes the material. You will have to buy a special glue for polystyrene foam or cement-based tile.

In this case, a primer is not necessary: ​​the compounds penetrate into the slabs to a sufficient depth and provide a high degree of adhesion.

After graduation plastering works re-priming is carried out for the final, finishing finish.

Stucco technology according to "Penoplex"

• The seams between the individual plates are blown out mounting foam. It is not necessary to seal them with plaster mixtures: they will become the cold bridges already mentioned. Leaving it unsealed is also not worth it: heat loss will be provided by convection, and voids can be squeezed under external influence.
• After hardening, excess foam (bubbles) is cut off with a knife flush with the surface, and all of it is rubbed to smooth out scuffs and bulges.
• The plaster mixture is diluted. Do not forget: the powder is added to the water, and not vice versa, otherwise the plaster will turn out to be heterogeneous.
• Approximately a meter wide wall is covered with a composition 2-3 mm thick. The height of the treated area should be such that you can easily glue a piece of mesh at a time: it is mounted only in a fresh composition.
• The mesh is cut off along the height of the smeared surface, applied to the wall and pressed so that it is completely immersed in the plaster. Smoothing is carried out from the center to the edges.
• The next piece of mesh is overlapped; the entry of one half to the other should be at least 10 cm.
• After reinforcing the entire wall, a break is taken to allow the adhesive layer to dry. In summer, 2-3 hours are enough, in cold weather or when high humidity better to wait a day.
• The dried reinforcement is rubbed with a grater made of wood or plastic with a grinding mesh, in circular motions, without excessive zeal and with equal pressure.
• After processing the entire surface, the final plastering is carried out. Its layer is the same 2-3 mm. You can use the same composition with which the paint grid was glued, you can apply a special finishing plaster.

After the final drying of this layer, the wall is rubbed again to maximum smoothness, cleaned of dust with a soft brush, vacuum cleaner or dry sponge and primed under the selected finish coat. At this stage, special care must be taken: some paints can destroy Penoplex by penetrating through the plaster, especially if it is applied with an insufficiently thick layer or has a gypsum base. Paints containing drying oil, benzene, xylene, toluene, acetone, polyester and coal tar, kerosene or gasoline are categorically not suitable.

When painting, it is also impossible to use the most common solvents, such as the same gasoline with kerosene or white spirit. Facade water-based emulsions, silicates and mineral paints based on cement and lime are suitable for painting plastered insulation. In principle, between how to plaster "Penoplex" and plastering any other surface, the difference is not too great. It is important to choose the right compositions for work and without fail to carry out reinforcement. The insulation protected by a plaster layer will last at least 10 years, and with timely renewal of the top coating and restoration of damaged plaster, it will last all 20.

The facade of any house requires high-quality finishing. It not only gives the building an attractive appearance, but also protects from various adverse effects of the outside world - from precipitation and direct sunlight.

To give the building an aesthetic appearance and protect the building, it is worth using.

There are quite a lot of types of this material, the choice can be made on the basis of different parameters.

For example, if the facade of the building is covered with foam, it is worth buying just such a plaster for foam.

The coating of such a plan is a high-quality finishing hardened layer, which is formed on the basis of a special plaster solution intended for finishing the facade parts of buildings and structures.

Important! Properly selected and applied plaster allows you to effectively level the surface of the outer walls, you can repair potholes and numerous cracks, as well as protect the building and give it a look that is fully consistent with individual taste preferences.

Modern facade plasters are in rather high demand, as this coating is characterized by a large number of positive qualities and properties.

Among them are such advantages as:

1. High strength. Facade plaster is a special shell of the house, thanks to its qualities it ideally protects the building from adverse factors.
2. Frost resistance This is an important advantage for most regions of the country. This indicator must be taken into account, since when frost sets in, the coating will simply crack. Facade plaster under penoplex is able to withstand temperatures up to minus 50 degrees.
3. Lifetime. The plastering process is quite complicated, but all the time and money spent are fully paid off by the optimal durability of the material. On average, facade plaster is able to last up to 15 years.
4. Vapor permeability- the ability to remove condensate. This prevents the process of destruction of the finish, as well as the formation of mold and mildew.
5. Ease of installation and maintenance. If desired, the plaster can be applied independently, and special care for the material is not required.

Thanks to all the advantages listed above, the plaster not only fits perfectly on the foam, but also performs all its decorative and protective functions.

Facade plaster for foam and expanded polystyrene - types and features

During the construction of private country houses mandatory use of special heaters. Among a large number modern materials penoplex deserves special attention. It is easy to use and comes at an affordable cost.

Despite these high quality characteristics, even penoplex needs some protection. For this purpose, special plaster is used from manufacturers such as "", "Ecomix", "Stolit".

These compositions are actually high level perform the following important functions:

• Effective moisture protection. Plaster, due to its qualities and properties, protects the insulation from destruction;
• Protection of penoplex from the adverse effects of sunlight;
• Significant improvement in overall appearance building.

As for manufacturers, it is not worth using different mixtures to cover one building, since each of them may have a different composition, which will lead to a decrease in the overall quality of the coating.

Universal plaster is consumed as economically as possible from 4 kg / m 2 for gluing reinforced mesh and up to about 6 kg / m 2 for full leveling of the outer walls of the building.

The mixture must be diluted sufficiently liquid, it must drain from the spatula. At the beginning of the work, a solution is prepared, after which you can start gluing the mesh itself, on which the foam plaster will be installed.

Surface preparation for application

The process of plastering penoplex is preceded by certain preparatory work. The surface must be carefully leveled, and this can be done by grouting.

With a well-conducted process, you can effectively remove all the bumps and pits. It is at the stage of grouting that it is necessary to carefully work out the surface of the outer walls. This is a very important requirement, since after applying the plaster, all the remaining problems and defects will be revealed to the eye.

Mesh work

After grouting, fastening work is carried out. This is an important and mandatory step in the plastering, as without a grid, the plaster will quickly crack or simply slide off. On the this stage you can use a grid that is designed specifically for facade work. The mesh density should be on average 140 - 160 g/m2.

It is from the density of the grid that directly depends on how even the layer of plaster will be.. In other words, the higher the density, the better and smoother the plaster layer will be.

NOTE!

The grid for facade work should be used alkali-resistant, since cement is often present at the base of the foam.

The acquired mesh is attached using a special adhesive mixture, which is applied with a thickness of 2-3 mm. The composition is simply applied to the surface and the reinforcing mesh itself is immediately applied.

The product must be pressed into the composition by about half, that is, the adhesive mixture must completely cover the surface of the mesh. The glue must be applied gradually, it is important that it has time to fully grasp, the mesh itself is attached in small segments.

The mesh must be pressed down with a smooth spatula during application. At the same time, the strips must be glued strictly overlapping, and not less than 10 cm. Everything must be glued very carefully, since non-glued compositions or applying the composition only to the joints will appear even through the fine finish.

Surface leveling

As soon as the mesh layer dries completely, the surface can be grouted. It uses a specially prepared sandpaper cloth or construction grater.

This should be done after the coating is completely dry.. The time of this drying cavity depends on the weather. The higher the temperature and the drier the air, the faster the applied plaster will dry.

If work is carried out in summer time, on average it may take up to three hours. If the finishing of the building is carried out in the cold season, you can start grouting in about a day.

In any case, there is no need to rush, as the plaster will not be of the desired quality and appearance. The grout itself is carried out without any effort, it is enough to carry out special circular movements and, moreover, counterclockwise. The process ends after all defects are completely smoothed out.

After that, the surface is leveled and another layer of plaster mixture is applied. Foam plaster is made using the same mixture as in the previous stages. When carrying out these processes, you need to use a spatula with which the mixture will be applied. The plaster layer should be approximately 3 mm thick.

Upon completion of these works, the final grouting is carried out. It begins only after the complete drying of the previous layer, this is not less than a day after the last layer has completely solidified.

CAREFULLY!

Expecting complete drying, you should not go to extremes, as there is a wait for more than four days, coating becomes very hard, so it will be very difficult to process it.

Facade plastering technology for insulation

If in the process of finishing the exterior walls it was decided to use powder putty, first it will need to be carefully diluted. To do this, about half the water is drawn into the bucket and the powder is carefully poured. In the process of falling asleep, you must constantly use a special construction mixer. As a result of the work carried out, the mixture should become similar to mashed potatoes.

Once the mixture has reached the desired consistency, it should be left for about 5 minutes and it is desirable that it be in a calm state. After that, everything is whipped and you can immediately get to work. If used, it can be applied to the wall without any preparatory processes.

Here are some tips to follow:

1. When performing putty, you need to use a wide spatula, on which the mixture is placed using a small and narrow spatula, which is placed in a bucket.
2. It is very important to ensure that the new finishing area is completely merged with the previously processed.
3. It is necessary to ensure that all joints are invisible.
4. Before applying putty, do not forget to treat the wall with a special primer. It is she who provides additional waterproofing.
5. The layer thickness should not exceed 5 mm.
6. After the layer dries, it also needs to be completely wiped. This process must be carried out no earlier than 3 hours after the mixture has been applied.

After carrying out work related to puttying, you need to apply a primer. With this composition, you can effectively remove all dust particles that may be present on the surface of the walls and make the surface as smooth as possible. Upon completion of these works, you can begin to carry out painting work.

Surface coloring

To give the walls the most complete look, many owners. The most important thing here is to take into account the type of pre-applied putty. There must be compatibility between it and the paint.

It is very important to avoid such paint compositions, which contain components such as:

• Acetone;
• Benzene;
• xylene;
• Toluene;
• drying oil;
• Resin;
• Coal tar.

These are quite common components for painting materials, but their use is unacceptable, since each of them is capable of destroying foam. The best option for painting walls insulated with foam, are paints made on the basis of minerals.

They are made from lime or cement, and these components, as you know, do not have the ability to react with insulation. Silicate paints are also suitable, which do not harm the foam. No less effective Decoration Materials, which belong to the category of water-based.

Also, it should be exactly facade paints, as they are characterized by high rates of reliability and resistance to adverse weather conditions.

Summing up

If it was decided to carry out work on plastering, subsequent puttying of the facade and painting it yourself, you should definitely follow all the tips and recommendations presented to your attention. It will not be superfluous to consult a professional who will help you choose the best suitable mixture, putty and paint. All compositions used must necessarily comply with the established requirements.

In contact with

Penoplex is a popular material used for thermal insulation. Its main advantages are high strength, density and water absorption. Used for thermal insulation of walls and floors country houses. The plastering process has its own characteristics, knowing that all work will be carried out efficiently and quickly.

Required fixtures and materials

To plaster the heat-insulating material, you will need:

• putty;
• mixture for plastering;
• putty knife;
• grater;
• scissors;
• reinforcing mesh;
• capacity;
• gloves;
• roller;
• sponge.

Surface priming

Compared to classic plastering, the thickness of the soil when finishing foam is 2-3 mm. Its main purpose is to mask the results of reinforcement on the surface and prepare the surface for the final cladding.

It is necessary to apply a primer to the penoplex after the first layer has set and a rough cleaning of the wall with sandpaper has been completed. And although stripping is not a mandatory procedure, it helps to reduce the amount of adhesive required for surface treatment. At temperature regime 20 degrees and medium humidity, the leveling primer layer is distributed after 6-12 hours. The curing speed depends on the absorption of the material by the walls. It is necessary to apply a primer of a thicker consistency than when attaching a reinforcing layer

Solution preparation

It is best to apply ready-made store mixes to penoplex. For wall cladding, the consumption will be 6 kg per 1 m2 and 4 kg for fixing the grid. When mixing the solution, you should strictly follow the instructions on the package.

For gluing a plaster mesh, it is necessary to use a mixture of a slightly thinner consistency than indicated by the manufacturer. To level the layer, the mixture is diluted so that it literally drains from the spatula.

Sticking plaster mesh

When plastering foam, an important step is the reinforcement of the plaster with a mounting mesh. Without this process, the dried layer will crack, and after a while it may completely fall off.

It is advisable to purchase a mesh designed for external work on the facade, which is made of plastic that is resistant to alkaline environments. Otherwise, the reinforcement will be subjected to negative influence cement mixture. The mesh density should be in the range of 140-160 g/m2. This indicator affects the smoothness of the layer and the ease of application of the material, which is extremely important for inexperienced craftsmen.

Procedure

Processing corners and slopes. Special mounting brackets are suitable for corners. But you can use a piece of a regular mesh, after bending it so that the edge is clearly defined.

Mesh preparation for walls. Cut off pieces from the roll, the length of which will coincide with the height of the wall, and the width is 60-100 cm. In this case, you should focus on the convenience of work in order to quickly glue the strips until the mortar sets. Spread the glue using a spatula, the width of which matches the width of the mesh pieces.

Mesh sticker. Attach the grid to the leveled plaster. To do this, you need to attach a strip to the upper edge, fix it with hand pressure and smooth it with a spatula, starting from the center. In order for the leveling to go as high as possible, a trowel is used, performing wide circular movements.

Using a similar procedure, you need to glue the subsequent strips of mesh on the foam until the entire surface of the outer walls is processed. The edges of the pieces are recommended to overlap each other by 5-10 cm.

If, in the process of smoothing the mesh with a spatula, “gaps” appeared in the resulting layer, then it is necessary to add an adhesive mixture to these places.

It is only necessary to wait until the applied plaster dries (in case of strong heat, the drying time will be about 2 days). Then take a grater with an emery cloth, put on a respirator and goggles. With smooth movements in a circle, start processing the applied layer, moving counterclockwise. The grater should be lightly pressed against the surface of the foam.

When troweling still slightly damp plaster, the grater's emery cloth must be changed frequently.

Plaster surface

At the final stage, roughing is performed - applying the main layer for leveling.

Procedure

Using a narrow and small spatula, you need to put a cement mixture on a wide spatula and distribute it over the surface of the foam in the form of even vertical strips. In this case, it is necessary to place the joints of the leveling compound in the middle of the strips of the reinforcing mesh. Then the joints will not seem thick.

For high-quality smoothing of the layer, a rule and a trowel are suitable. The thickness of the plaster on the penoplex is 3-5 mm. To check the evenness use the building level.

The layer should dry out, it will take 1-4 days. At this time, you need to wipe the rough plaster with sandpaper, by analogy, which was used to process the reinforcing layer.

The longer the leveling layer dries, the higher the strength of the plaster will be. If it is dried out, it will take more effort and material to grout the wall.

At the end of all the work, the walls will have to be beautifully decorated. Paint can be used for this. It's simple and inexpensive option, but it will not give the plaster additional protective properties, while reducing the life of the thermal insulation and will not last long.

The simplest and most interesting outwardly are facade plasters: “fur coat” or “bark beetle”. The peculiarity of these materials is that the composition contains large particles, due to which an unusual texture pattern is formed on the surface. The sale of such material is carried out in finished semi-liquid form in plastic container. Consumption will be 1-2 kg per 1 m2 with a layer thickness of 2-5 mm.

The final stage begins with the application and distribution of the mixture over the surface of the wall. Next, you need to form a relief. For these purposes, special graters are used, but experienced builders create texture with such improvised materials as a sponge, a hard brush, or a crumpled plastic bag.

It is important to ensure that the pattern is the same over the entire surface of the wall. If any plastered area differs in color, then this can be masked with a layer of paint. But differences in the relief pattern will be noticeable even on a painted wall.

Conclusion

The foam plastering process is a simple process that even an inexperienced master can do with his own hands. The main thing in this matter is to fix the material with high quality so that the structure does not deform. At this stage, beginners will not be hindered by the help of a specialist, since he is the most basic, and the rest of the work is done alone. In addition, it is worth using materials of proper quality, in order to avoid problems in the process of plastering and extend the life of the structure.

If you need to quickly and efficiently insulate the walls from the outside or from the inside, then penoplex will be an excellent solution. In general, this is the name of one of the brands that produce extruded polystyrene foam, but the people call it all materials of this kind. Therefore, the description is suitable for any materials made by extrusion.

Features of insulation and materials used in the work

Very often there is a question - is it possible to plaster penoplex without preliminary preparation? Everything is simple here - if you do not follow the technology, then the coating will most likely fall off in a couple of years. But if you do everything right, then the plastered surface will last a very long time.

Most often, insulation is used outside buildings, less often - indoors. This is due to the fact that the penoplex almost does not allow evaporation and, when used from the inside, the dew point can be inside the wall, which negatively affects its strength.

The choice of plaster

If you decide to do the plastering with your own hands, then you need to choose the composition for finishing. There are currently three main options:

• Mineral compositions. They are made on the basis of cement and have whole line pluses: low cost, durability and good resistance to weathering and moisture. This is the most popular variant of plaster mixtures, which is used most often. The composition is versatile, it can be used both for gluing a reinforcing mesh and for finishing the surface, but there are also separate options with fillers for decorative finishes.

• Acrylic based formulations. Most often used for finishing and may have different structure. They are durable and have good moisture resistance, most often sold in ready-made in plastic buckets. A significant disadvantage is the high cost, this option will cost much more than the first, moreover, such mixtures cannot be used for gluing the mesh.

• silicate mixtures. An excellent option for facades, characterized by high elasticity and resistance to moisture. On the surface, a moisture-proof layer is obtained, which at the same time has good vapor permeability from the inside. Most often, the compositions are sold ready-made and have fillers in the form of pebbles or other materials, it all depends on the texture that is obtained during finishing.

• Silicone based formulations- most modern solution. The coatings are reliable and durable, they are not afraid of moisture and do not crack over time, since the layer is elastic and stretches under deformation effects and temperature changes. The only negative is the high price, this is the most expensive solution to date.

Work materials

Except plaster composition you will need a number of other materials:

Illustration	Description
	Dowels for thermal insulation. Used for additional fastening of the material on the wall. Even if you have glued the sheets securely, be sure to install additional fasteners before plastering them. It will eliminate surface deformations. The length is selected according to the thickness of the insulation, the fasteners must protrude at least 50 mm.
	facade mesh. It is used to reinforce the surface and create a stabilizing layer that is resistant to cracking and improves the adhesion of the plaster to the smooth surface of the foam. The mesh density must be at least 160 grams per square, when choosing, check whether the cells are even and whether the material is stretched.
	Facade primer. It is applied on the first leveling layer to improve adhesion and strengthen the surface. Use only special compounds that are weather resistant.
	Mesh corners. To strengthen the corners of the building and the edges of the openings, you need a special corner with a grid. Usually it is made of plastic, therefore it has excellent moisture resistance and does not collapse under the influence of water.

The working process

Let's figure out how to do the job right:

Illustration	Description
	Surface being prepared. First, the sheets are fastened with dowels, if this has not been done before. There must be at least 2 fasteners per sheet if it has been securely glued before. Secondly, the plane is checked, if there are protruding sections, then the wall surface is leveled, it is most convenient to use a special grater or planer to quickly remove excess material. The smoother the surface, the easier it is to plaster. If there are noticeable gaps between the sheets, it is easiest to fill them with mounting foam. The protruding parts are cut off after the composition dries.
	Preparing a solution for a leveling layer. Most often, an adhesive composition is used for work, with which the penoplex was glued. It is most convenient to work with a drill or a special mixer, a power tool significantly speeds up the workflow, in addition, the quality of the finished composition is much better than with manual mixing. The proportions of the components will be prompted by the instructions on the package, follow its recommendations.
	Work is done like this: A piece of mesh is cut off, the length should be 10-20 cm more than the height of the wall. Work begins from any site, the grid is located vertically, after which a layer of glue approximately 3 mm thick is applied to it. The mesh should be pressed into the surface and firmly adhere to it. You can do otherwise: first, apply glue to the foam with a notched trowel, and then press the mesh and level the surface with an ordinary facade trowel.
	Corners reinforced with corners. To do this, the elements are cut into pieces of the desired length, after which they are slightly seized with glue, and then completely tightened with the composition.
	Excess mesh at the bottom is cut off with a construction knife. This results in a perfect match and there is no need to accurately measure anything in advance.
	The first layer rubs off. No need to wait for the surface to dry completely. The work is done 2-3 hours after applying the composition, the grater allows you to remove small flaws and bring out the plane. After leveling, the walls are primed, it is most convenient to apply with a roller. Usually one layer is enough, which dries from 1 to 4 hours.
	Finishing is done like this: The plaster mortar is prepared as recommended in the manufacturer's instructions on the package. If you have a ready-made composition, then before using it must be thoroughly mixed. Decorative plaster is applied as prescribed by the instructions. Different variants distributed in different ways, it all depends on the type of composition and texture that you want to get in the end. If necessary, after the coating has dried, the walls are painted. But it is easier to use a color composition to simplify and speed up the work.

Conclusion

Now you know what compositions can be used for plastering foam and how to properly organize the workflow. The video in the article will tell and demonstrate some of the aspects discussed above so that you understand them even better. If you have questions on the topic - write them in the comments under the review.

If you want to express gratitude, add a clarification or objection, ask the author something - add a comment or say thanks!

Since plaster is still one of the most popular ways of finishing walls and ceilings, the use of this method of applying a decorative and protective layer on a reinforced foam plex is fully justified. Despite a certain roughness of the surface of the extruded polystyrene foam boards, for a more reliable fixation of the layer of the hardened building mixture, a foam plaster mesh is used. Properly reinforced mesh for foam allows you to provide thermal insulation material protection and reliable lining layer for finishing plaster.

Why is foam reinforcement needed?

A well-reinforced layer of foam insulation, made in compliance with all installation rules, without the use of metal fasteners, creates reliable thermal protection of a building or structure. But the same insulation itself needs protection from the destructive effects of a number of natural factors. No, he is not afraid of cold or rain. But prolonged exposure to sunlight can destroy thermal protection in one season.

The use of plastering the surface of foam plastic, followed by strengthening the protective finishing layer (siding, for example) is quite justified, but significantly increases the cost of work. The created reinforced mesh for foam plastic plaster reliably performs protective functions, preventing premature destruction of expanded polystyrene obtained by extrusion. How can it protect against all-penetrating ultraviolet rays?

This task is perfectly handled by a reinforced layer, which is carried out over the entire outer surface of the reinforced insulation. This layer consists of a special adhesive and a facade mesh embedded in it. It withstands the stresses that occur on the insulated surface when the temperature changes.

The device of the reinforcing layer on the fixed foam has its own characteristics:

• mesh strips are overlapped (up to 10 cm) with horizontal and vertical connection;
• the strip should be completely immersed in the adhesive layer, but not more than half of its thickness;
• the reinforced layer made on the reinforced insulating material should not be thicker than 3 mm.

For reliable protection of structural elements subjected to the greatest mechanical loads (basement and walls of the first floor, balconies and terraces), it is recommended to strengthen them with a double layer. When strengthening the reinforcing element at the corners of the house, it wraps around the corner of the building (by 15 cm).

Reinforcement of foam insulation

A completely natural question arises: “Having fixed the penoplex on the wall - how to fix the mesh?” Based on the basic requirement of thermal insulation systems, the use of metal fasteners is categorically contraindicated, since the “cold bridges” created in this case will turn all efforts into a simple waste of money, time and effort. What to do? How is the mesh fastened to the foam, if the metal is contraindicated?

In the event that the thermal protection layer is mounted on a surface where structural movements are not expected, the mesh for foam plastic plaster is fastened with an adhesive mixture (it is embedded in the adhesive layer, and if necessary, a second layer is made). If the foam mesh is attached to the insulating material in those places where movement is expected, plastic dowels (fungi) cannot be dispensed with, or thermal panels with a ready-made polymer-cement coating must be used.

An approximate technology for creating a reinforced layer for the subsequent application of plaster is as follows:

1. On the surface of the foam 1 meter wide (standard width of the facade mesh) is applied with the smooth side of the trowel, which is distributed evenly with a notched trowel.
2. The reinforcing element is applied to a fresh layer of glue and pressed into the adhesive layer with a smooth spatula (grater).
The following strips are overlapped (up to 10 cm).
3. Plastering is carried out only after the final drying of the reinforced layer.

In the process of work, the question may arise: “If foam plastic was used to insulate the external slopes, how to fix the mesh and how to achieve a flat vertical surface for the subsequent application of plaster?”. Insulation of window slopes and doorways is done as follows:

1. Before fixing the insulation on the opening, it is necessary to stick the facade mesh, wrapping it on the wall by 15 cm.
2. Penoplex is attached to the glued mesh so that it protrudes from the wall by the thickness of the insulation plus 3 mm (the thickness of the reinforced layer).
3. Wooden planks are placed under the penoplex, creating an expansion joint.
4. The mesh for subsequent plastering is glued to the insulation (be sure to wrap and glue at least 15 cm to the wall).
5. Before plastering - the corners are ground with sandpaper or a special float, which allows you to create an even layer of plaster.

Thermal panels with polymer cement plaster

It would seem that what is easier, having strengthened the penoplex - plastering on the grid can be performed at any free time. Unfortunately, the creation of a high-quality and reliable reinforced layer requires a certain temperature, since complete drying of the adhesive mixture is necessary. But do not stop the work in the cold season, especially since the installation of penoplex can be performed at any time of the year. It is for these purposes that the manufacturer created thermal panels with a polymer-cement coating (foam with a reinforced mesh, which is already plastered with a special polymer-cement composition).

Such building panels, having all the characteristics of a high-quality insulation, allow you to quickly install foam plastic with a plaster mesh, regardless of the weather. This significantly reduces the time of work, and applying the final layer of plaster is not difficult, since there is a prepared surface. In addition, these panels, prepared at the factory, are used to create decorative columns, arches and perform other finishing work. Thermal panels offered by PENOPLEX SPb LLC are of high quality and reliable.
