How to properly putty plasterboard ceiling? The process of puttying plasterboard ceilings Puttying plasterboard ceilings

Finishing the ceiling with plasterboard - good way get an even coating without cracks and gaps, in addition, under it you can hide insulation, wiring and other communications. Fine finishing of drywall usually comes down to painting with interior compositions, for which it is necessary to prepare it - apply several layers of putty.

Puttying the ceiling: purpose and stages

Drywall sheets have a fairly even surface, therefore, unlike concrete floors, they do not need careful alignment. If the ceiling frame is made correctly, using a level, then the plasterboard ceiling is a flat plane, which is violated only by gaps at the joints and fixing screws recessed into the material. These irregularities must be puttied, after which the ceiling should be given a uniform texture.

If the ceiling has a complex multi-level shape, the task becomes more complicated. In this case, you need to display the outer and inner corners, curvilinear elements, adjunctions to the wall. For these works use the same materials and tools as for simple ceiling, but the duration of the repair and the number of stages may vary.

The main stages of work on puttying the ceiling:

• preparation and priming of the drywall surface;
• applying starting putty on seams, corners and joints;
• leveling and priming of treated surfaces;
• applying finishing putty to the entire surface of the ceiling to give a uniform texture;
• polishing the ceiling with a paint grid and eliminating the slightest irregularities;
• primer, dry

It is not worth neglecting any of the steps - this can lead to peeling of the paint during application or after it dries.

Materials for puttying the ceiling

The choice of putties in hardware stores is quite large, and it is important to know their features in order to choose the most suitable composition.

According to their purpose, they can be divided into two groups:

• putties based on gypsum or polymer for dry rooms;
• moisture-resistant putties on a cement or polymer basis.

In rooms with normal humidity, you can use any composition, in rooms with high humidity it is better to use moisture resistant mixtures.

Required tool

Before starting work, it is necessary not only to purchase the material in the right quantity, but also to prepare the necessary tool.

You will need:

• spatulas, narrow (no more than 10 cm), medium (20 cm) and wide (30-35 cm);
• metal trowel;
• grater with paint grid;
• roller or wide brush for priming the surface;
• stable container for mixing dry formulations;
• construction mixer or drill with a nozzle;
• sickle tape with an adhesive layer;
• corners made of metal or plastic for finishing external corners if the ceiling has a complex shape.

To prepare a plasterboard ceiling for applying putty, you will also need a screwdriver and a sharp mounting knife, and a construction stapler to fix the corner. It is also worth preparing goggles and a respirator - when grinding, they will protect your eyes and nose from dust.

Preparatory work is an important stage, during which defects in the fastening of drywall are eliminated and seams and joints are prepared for better filling with putty mixture.

1. It is important to check the tightness of all mounting screws. According to the rules for attaching their caps, they should be approximately 1 mm below the drywall surface. You can check this visually or by running your hand along the surface of the ceiling at the attachment points. If part of the screws protrudes above the plane of the sheets, they are pulled with a screwdriver. If the screws are sunk too deep, they are loosened or unscrewed and replaced with longer ones, twisted according to the rules.
2. Carefully inspect the joints of the sheets and their adjoining to the walls. There should be a gap of at least 2-3 mm between the wall and the sheet, then when filling with putty, a dense and even seam is formed there, which eliminates the appearance of cracks. The factory edges of the sheets do not need additional processing. The cut edges should be chamfered at a 45° angle to ensure good filler filling.
3. It is also necessary to check outside corners: drywall sheets should not protrude beyond the corner. To do this, a spatula is first carried out along one plane forming an angle, and then along the other. The spatula should not catch on the edge of the sheet. If necessary, trim it with a knife.

For priming drywall, water-soluble compounds are used. When applying them, it is important not to overdo it. If the drywall surface is wetted too much, not only the top paper layer will get wet, but also part of the internal gypsum filling. This will lead to detachment of the cardboard, wrinkles, and later to bubbles.

1. The roller is put on a long handle - so you do not have to constantly carry a stepladder or stand.
2. The primer is applied in two layers. The first is along the long side of the drywall sheets, the second is perpendicular to the first. The surface of the ceiling is quickly rolled with a roller, not lingering in one place to avoid waterlogging. Let the primer dry completely between coats.
3. The joints are primed with a brush, since the roller does not penetrate into the cracks and gaps. Do the same with corners and junctions to the walls.

Important! Alkyd-based primers cannot be used for drywall - they destroy the paper layer, and later it will crawl along with the paint.

A layer of starting putty is not applied to the entire surface of drywall - it is already quite even. At this stage, it is only necessary to putty joints and seams, as well as the heads of self-tapping screws.

1. When puttying joints formed by sheets of drywall, use a mesh tape - sickle. It has an adhesive layer, thanks to which it is quickly and firmly attached to the seam. Fix it so that the gap is in the center of the tape.
2. Mix the Knauf-Fugenfüller or Weber.Vetonit Siloite repair mixture according to the instructions on the package. It is more convenient to do this with a mixer or a drill with a construction nozzle. One portion of the mixture should be used within 1-1.5 hours, this must be taken into account.
3. For puttying at this stage, you will need spatulas of different widths. For sealing joints, it is convenient to use medium and wide: with the middle putty mixture is collected from the container, applied to the joint over the sickle, first perpendicular to the seam, then along it.
4. After finishing the entire joint, it is carried out several times with a wide spatula or trowel to align it as much as possible and remove excess. This will allow you not to grind the dried putty and avoid dust.
5. The heads of the self-tapping screws are covered with a narrow spatula crosswise, after which they pass with a wide spatula over the entire surface of the ceiling.
6. The putty is dried naturally for 1-2 days, depending on the composition.

In the decoration of apartments, complex multi-level ceilings are sometimes used. Often they have curvilinear elements - waves, circles. These elements form external and internal corners, the finishing of which is a more difficult task than simple sealing of joints. To align them, use a sickle or a special metal or plastic corner.

Finishing putty

Before finishing, all puttied elements must be primed and dried. For finishing putty, use any composition with a fine-grained structure. For coloring in bright hues it is better to use mixtures that form a white surface when dried. Putty is prepared according to the instructions in the right amount.

1. Finishing putty is applied to the entire surface of the ceiling with a wide spatula. The wider it is, the smoother the surface will be. They begin to putty from one of the walls, bringing out the corner, and continue with wide stripes.
2. After covering the entire ceiling, the putty must be dried well and the uniformity of the coating is assessed using a portable lamp. She illuminates certain sections of the ceiling, observing the refraction of light. Shadows and highlights indicate that there are irregularities on the ceiling.
3. If necessary, apply one or two more layers of finishing putty, be sure to dry each of them.

Putties on cement base used for wet rooms are worse aligned and overwritten, so it is better to use polymeric waterproof compounds for finishing.

Grouting and preparing for painting

The final stage of work, allowing you to get a smooth surface without scratches and roughness. The finer the fraction of the finishing putty, the smoother and glossier the ceiling is.

Important! Work on grouting and grinding the ceiling is carried out in a respirator and goggles! Putty dust can be inhaled and cause health problems!

Properly prepared for painting, the ceiling has a smooth surface without cracks, dents or other damage. The paint lays on it evenly, without glare and streaks. For the result to please you, follow all the stages of finishing and follow the advice of professionals, because right technology is the key to a successful repair.

In construction, gypsum plasterboard, or GKL, is often used. Made from this material interior partitions, arches and false ceilings. In the latter case, it allows you to hide all the irregularities and build almost any structure in shape. After the main work, the ceiling can be wallpapered, painted or even tiled. But before that, it must be covered with putty. How to putty a plasterboard ceiling for painting? What are the features of this process?

The building materials market is represented quite wide range of putty mixtures. That is why the issue of their choice should be taken especially seriously.

Puttying the ceiling can be done in two types of material:

1. dry,
2. liquid or viscous.

Any primer can be used. The main thing is that it is suitable for working with putty mixtures. After work, drywall should dry thoroughly (about three hours).

Puttying

So, how to putty the ceiling? First of all, it is necessary to hide the joints and screws. This can be done with self-adhesive mesh or paper tape.

Mesh attachment

The grid is attached to the ceiling with a working solution. The process looks something like this:

• Dilute the putty as written on the package. By consistency, it should resemble thick sour cream.
• Using a spatula, apply the solution to the seam. Close up so that it remains visible.
• Cut off the desired size piece of mesh. Attach it to the putty and press lightly.
• Apply another layer of solution on top of the mesh. It is important that there is an acute angle between the spatula and the ceiling.
• In the process of work, you need to make sure that there are no threads left anywhere.

Paper tape is most often used in rooms with a high level of humidity. The process of gluing it looks the same as in the case of working with a grid. To fix the paper, it is better to use the finishing mixture.

Applying the material to the entire surface

When everything is glued, the plasterboard ceiling plastering begins directly. First you need to pay attention to the seams, screws and corners:

1. At the joints, the solution is applied in two stages. The second layer is applied only after the first one is completely dry. At the end, you need to clean all the seams with sandpaper.
2. Before puttying the screws, their locations must be carefully primed. Then, using a small spatula and a finishing mixture, “hide” the holes in a criss-cross pattern. This should be done when the joints are dry.
3. We putty the corners first on one side, then on the other. Moreover, work on the second begins after the first one dries.

As soon as the seams, screws and corners are ready, you can begin the main part of the work. How to properly putty plasterboard ceiling?

• Using a small spatula, spread the already prepared mixture on a large one.
• Apply the solution to the ceiling GKL and carefully distribute. The layer should be thin, maximum 2 mm. You need to putty quickly, otherwise cracks may appear.
• In the process of puttying the ceiling for painting, the excess mortar must be removed immediately. To do this, use a spatula, previously moistened with plain clean water. These residues can be added to the bulk of the composition.
• The ceiling must be given time to dry (about a day).
• If errors remain, they can be eliminated with a smaller spatula.
• Final stage- grinding. Here you will need sandpaper. It will help remove scratches and roughness.

The final stage

Achieving the perfect evenness of the putty layer is not so simple. To correct the shortcomings, it is necessary, as mentioned above, to do the grinding of the plasterboard ceiling with your own hands. The process should be started only after the solution layer is completely dry.

In most cases, this takes up to seven days. During this period, the room can and should be ventilated. As soon as dark spots disappear from the ceiling, and it becomes matte, you can begin work.

At this stage, "zero" sandpaper is used. If possible, you can use a special grater.

To make your ceiling perfect, you need to use the right lighting. Experts recommend using spotlights. But you can get by table lamp. The beam of light must be directed to drywall at different angles. This will help to see and subsequently correct even the smallest flaws.

How to putty plasterboard ceiling on your own? First you need to prepare the mortar and working tools, and then you can start working, preferably in this order: seams, screws, corners and the rest of the surface.

Puttying a plasterboard ceiling requires a certain sequence. Otherwise, all the defects that are present on the base will appear on the painted ceiling surface. To prevent these troubles, it is important to know how to putty plasterboard ceilings.

Experts recommend purchasing those with a longer service life, not afraid of temperature changes. Another advantage of dry putty is the ability to prepare dosed portions necessary for work.

According to the type of connecting element, putty is:

• plaster. This option is best suited for finishing plasterboard ceilings. natural material and fillers that make up the mixture improve its physical properties;
• cement- the most moisture resistant and resistant to temperature extremes. The main disadvantage of cement compositions is significant shrinkage after the putty dries, the appearance of cracks on the surface;
• polymeric– universal finishing material, superior properties of the two above composition. Polymer mixtures can be used in any premises, regardless of the degree of humidity and temperature.

If you are puzzled by the question of how to properly putty plasterboard ceilings, then you should know that the surface is primed not only after the putty has dried, but also before it is applied to the plasterboard to improve the adhesive properties.

When choosing a primer for work, consider the method of further finishing the ceilings:

• for painting or light wallpaper, a primer with surface penetration or with medium adhesion is suitable;
• it is better to fix heavy wallpapers and tiles on a surface treated with a maximum penetration primer;
• in rooms with high humidity it is necessary to use moisture-resistant solutions.

On a note! Usually, a universal acrylic primer is used for standard GCR. It penetrates well into the porous structure of the material, has excellent adhesion and air permeability, and dries fairly quickly.

Putty consumption

As a rule, it is indicated on the packaging, taking into account the applied layer thickness of 1 mm.

Calculate the consumption of material according to the following formula:

1 m * 1 m * 0.001 m = 0.001 m³

Now we can determine how much mixture is required to putty the ceiling surface per 1 m² with a layer of the required thickness:

0.001 m³ * B (layer thickness) * composition density (kg / dm²) \u003d A kg / m².

The manufacturer indicates the density indicator on the packaging. Standard values ​​for different types of putties range from 0.8 kg/dm² to 1.6 kg/dm². Moreover, the higher the density, the more material you need.

Number of putty layers

The mixture is applied to the ceiling with a wide spatula, which ensures that the composition is evenly distributed over the ceiling surface. It is necessary to cover the drywall with at least two layers of putty - starting and finishing. The starting putty is applied in a thick layer, and the finishing putty is applied very thin in one go and around the entire perimeter of the ceiling, distributing it in such a way that there are no transitions.

Plasterboard ceiling plastering technology

In order for the puttying of the plasterboard ceiling to be successful, it is necessary to strictly follow the instructions for applying the composition. Otherwise, even a properly selected mixture will not be a guarantee of success, and you will not be able to qualitatively finish the surface of the ceiling before painting it.

Standard tools for puttying ceilings are as follows:

• metal bucket;
• construction drill with mixer nozzle;
• dust brush;
• grater with fine-grained sandpaper;
• construction knife;
• spatulas of various sizes.

From the materials you will need:

• putty;
• primer;
• reinforcing tape or mesh-serpyanka.

Ceiling preparation and cleaning

Before you need to prepare the material for finishing work as follows:

• Check for protruding screws. To do this, draw a spatula over the surface of the drywall base, twist all the caps protruding from the material;
• remove dust with a brush;
• mix up a small amount of putty, cover up holes from self-tapping screws, fill the seams between sheets of plasterboard;
• cut a sickle or paper tape along the length of the seam, put it on fresh putty, slightly pressing the mesh into the material;
• after all the seams are finished, another layer of putty is applied to them, using a wide spatula so that the composition closes the cracks.

Ceiling primer

Primer application deep penetration on a plasterboard ceiling - this is an indispensable condition for a successful finish. Thanks to the primer, the adhesive properties of materials are improved. In work, use a roller or a wide brush, carefully prime the joints between the sheets and the puttied caps of the fasteners with a small brush.

To prepare a working solution, you must:

• fill the prepared container up to 1/3 with water;
• gradually add putty and mix the composition well with a construction mixer. The finished composition should take on the consistency of thick sour cream;
• now let the mixture stand for a while so that all the lumps are soaked, beat it again with a mixer.

Important! After you have mixed the putty ready for work again, you can no longer carry out such manipulations with the material, since its structure will be broken, strength and quick adhesion will deteriorate.

The solution should not be prepared in large quantities, as it thickens quickly. Prepare as much mixture as you can work out in 30 minutes.

Puttying the plasterboard ceiling takes place in several stages:

• with a wide spatula, located at an angle of 15-20 degrees to the surface of the ceiling to be finished, apply the putty in cross movements so that there are no streaks left;
• leave the ceiling to dry completely;
• now take a bright flashlight and examine the quality of the finish from different angles. If you find cavities, fill them with liquid putty.

How to putty plasterboard ceilings correctly

Seam sealing

In addition to the seams that were formed on the gypsum board during production, it is also necessary to pay attention to the seams resulting from the process of cutting the material. It is undesirable to impose a sickle or paper tape on such places. To seal them, you need to use a thick layer of putty mixture, but first you need to embroider the seam with a construction knife, and fill the recess special mixture, designed for sealing seams on gypsum boards. The composition is applied in two stages, between which you need to take a break for the drying time of the material.

The situation is somewhat more complicated with corners than with flat surfaces:

• putty one side of the corner in the usual way, wait for it to dry;
• do the same with the other side.

The most important thing on this stage do not rush and wait for the mixture to dry completely. Then you will get clear right angles of 90 °.

Last layer

If before that you worked carefully, you will see a smooth and even surface of the ceiling. It remains only to apply the finishing putty. Proceed as follows:

• distribute a small amount of material along the entire length of the base of a wide spatula;
• now apply putty on the ceiling, stretching it with a thin layer of 1-2 mm over the surface. Try to observe the specified thickness so that depressions and drops do not form.

Important! Finishing layer it is necessary to putty ceilings very quickly - when dried, the composition begins to crack.

Ceiling grinding

After the finishing putty has been applied, the ceiling should dry well before you move on to the next step. This may take 4 to 7 days.

To grind the surface, use fine-grained sandpaper and a special grater that clamps the sandpaper. Treat the surface in a circular motion, highlighting the sanded areas with a flashlight.

Finishing

When the previous stages of finishing are completed, you can proceed to the design of the ceiling space in any chosen way. In this case, be sure to apply another layer of primer on the puttied surface of the ceiling.

Sometimes you can get by with less work and close up only the seams and recesses from the screws. This is allowed in the following cases:

• for finishing, you used high-quality plasterboard with a smooth surface and no defects;
• it is supposed to paint the ceiling with textured or viscous paints.

The use of acrylic compounds requires a perfectly flat and smooth surface.

To prevent peeling pieces of putty from sticking to the roller or brush during the staining stage, use the following recommendations:

• use moisture resistant ;
• add a small amount of water-repellent primer to the usual mixture;
• before proceeding with painting, cover the ceiling with a moisture-resistant primer;
• when painting the surface, work with a roller quickly, not lingering in one place for more than 2 seconds.

How long do different types of putties dry

All building putty mixtures must be diluted with water. After the liquid evaporates, the material will acquire its inherent strength and hardness. The drying time of the composition depends on the conditions environment and type of surface to be treated. If the surface is porous and absorbs moisture well, the putty will harden much faster. The average time is approximately 24 hours. But the masters advise to wait at least a week before starting to grind the surface.

If speak about different types putties, the hardening time for them will be different:

• hardens in 3-6 hours if the material was applied in a thin layer;
• cement putty will dry in a day, while the layer thickness should not exceed 4 mm;
• the surface finished with a polymer mixture will be ready for further work in 3-4 hours.

The plasterboard ceiling plastering technology is simple, so you will be able to do the work yourself. For a more visual acquaintance with the process, we recommend watching the video for the article.

Puttying ceiling structures is laborious and requires a special approach. This work is best done by a team of proven professionals.

However, following detailed instructions, which describe how to properly putty a plasterboard ceiling for painting, even a beginner will be able to cope with this matter without much difficulty.

Do I need to putty drywall before painting? After all, the material is made without irregularities and has a uniform texture. It is necessary to putty the drywall surface, because the places where the screws are screwed in and the joints of the plasterboard do not make the surface perfectly smooth. In addition, without pre-treatment of the entire material, it will absorb more ink, which will lead to uneven color shades. The algorithm for working with drywall structures is concise:

• ceiling assembly;
• primer and putty;
• structure painting.

First of all, you need to choose the right mixture for putty. Several factors influence the choice:

Factor:		Blend Description:	Blend Description:
Readiness of the composition for use	Dry mixes are cheap, keep sealed longer, do not deteriorate with temperature fluctuations		Ready mixes are easy to use and do not deteriorate for a long time even after opening the package
The intended purpose of the composition	The starting putty is suitable for primary processing of the material (covering joints, obvious gross defects, cracks and chips)		Finishing putty is intended for the final leveling of the surface for painting.
The composition of the putty mixture	Cement putties are suitable for use in bathrooms, swimming pools and kitchens.		Gypsum mortars are designed for warm, dry rooms

Polymer putties have universal qualities and can be used in any conditions. Drywall plastering tools:

• bucket and drill with a mixer;
• wide brush;
• spatulas of different sizes;
• roller;
• sickle mesh (for masking and fixing seams);
• abrasive mesh and grater;
• flashlight or lamps to illuminate the surface;
• primer and putty mixture.

Preparatory work before puttying the ceiling with your own hands

When answering the question of how to properly putty drywall for painting, you need to remember about the mandatory surface preparation before processing. After collecting the drywall construction, you must wait from a week to 14 days for it to shrink. If you start puttying too early, the layer may crack, which will lead to repeated work and waste of money.

Before work, you need to level the surface, remove the protruding parts, make sure that the screws do not protrude from the surface. Drywall must be cleaned of dust with a brush so that the mixture lies evenly and directly on the surface.

The stage of priming the ceiling should also not be skipped. The primer is designed to increase adhesion (adhesion) between the material and the putty mortar. Masters recommend using acrylic solutions for priming. They have a low cost and are used quite sparingly.

Puttying seams

After the initial processing of the GKL, the stage of filling the seams with putty begins. The work will be easy if you follow a clear step-by-step instruction:

1. Direct factory seams that form at natural seams drywall sheets, are sealed with putty with a small recess for subsequent reinforcement with a special mounting tape - sickle.
2. Serpyanka is glued to the seam and slightly recessed into the putty.
3. Next, the surface is leveled with a solution and brought to one level.
4. The seams that appeared after cutting the drywall do not reinforce. They need to be expanded and puttied.

After the putty has dried, the surface must be carefully sanded without removing a thick layer of mortar. This is a rather dusty stage of work, so you need to take care of the respiratory tract in advance with a respirator. The floor in the room can be covered with a special construction coating to facilitate cleaning.

Finishing the corners of drywall construction: step by step instructions

The plasterboard ceiling can be presented in the form of a multi-tiered structure. For high-quality puttying of corners in this case, you will need special perforated corners. They will serve as the basis for gluing sickle. The tape is attached along the center line inner corner, puttied and leveled with a special tool. To strengthen the outer corners, special plastic or metal corners are used. They need to be pressed into the freshly applied putty, remove the excess solution. Corners are sealed until the surface is completely leveled.

Finishing putty plasterboard structures

How to putty plasterboard for painting walls at the final stage? After the starting solution is completely dry, you can proceed to the last stage of puttying work.

Before removing the walls and ceiling from drywall for painting, the surface must be primed again. The primer is best applied with a brush to prevent smudges, but if convenient, you can use a roller. When working with ceiling structures, for safety, it is better to use a tool with a long handle and prime while standing on the floor. The aesthetic appearance of the ceiling depends on the quality of the puttying work at the final stage. If small irregularities and flaws in the walls can be hidden with wallpaper, then the ceiling, which is most often painted, should be perfectly even.

Since drywall itself is smooth, the finishing putty can be applied in one or two layers. Putty is applied with a wide spatula. Before applying the next layer, the previous one must dry and be treated with a primer. The last stage of work on puttying a plasterboard ceiling is its grinding. Here it is important to take care of good lighting, which will help to identify and eliminate possible flaws and surface irregularities. Grinding is done with a special grater and fine-grained emery skins.

Recommendations for plasterboard ceiling plastering

For work, you need to choose only high-quality compositions. A good mortar is easier to work with and more likely to successfully putty the surface on your own. Do not neglect the starting putty. From the quality of work to initial stage the end result will depend.

You need to check the work carefully, because any minor and small flaw can ruin the whole look of the structure after painting. Puttying the ceiling is best left to professionals. Self-filling the ceiling can be done after a competent study of the technology and the process of working with plasterboard structures.

Photo gallery of finished works

After installing drywall sheets on the frame, the suspended ceiling cannot yet be considered finished.

The time has come for finishing work, that is, priming and puttying the surface. They are needed so that the wallpaper or paint that you want to apply to the surface is firmly held. In fact, to know how to putty a plasterboard ceiling and easily do it yourself, you just need to follow the exact instructions using the right set of tools.

Sealing joints in drywall

What will be needed to complete the work?

• Container for putty;
• Drill (regular or special) with a mixer;
• Brush-brush;
• Grater with sandpaper;
• Paint knife;
• Wide and narrow spatulas.

Sometimes they can also mention a building rule and a spotlight on a tripod.

Of the materials for puttying drywall on the ceiling, you will need:

• Serpyanka, or reinforcing tape;
• Primer;
• Putty.

Preparing the seams before puttying: doing the jointing

Plasterboard jointing

When you have prepared everything necessary materials and tools to get started, the first thing to do next is to embroider the seams.

This is understood as the removal of ribs from the edges of the GKL at an angle of approximately 40-50 degrees. After that, the joint becomes easier to putty. Jointing is not carried out for side joints, which are already usually made thinner and more convenient for puttying, as well as for edges that adjoin walls, because they are usually covered with baguettes and other structural elements.

To make the stitching, you will need a paint knife. With it, you simply cut off the edges of the sheets at the right angle, thereby exposing their core, that is, the gypsum part. This work can be done by eye: the main thing is that after stitching it is more convenient for you to process the seams.

Cooking putty

Studying the details of how to properly putty the ceiling from drywall sheets, you need to ask about how to properly knead the main working material - putty. To do this, you will need to do the following:

• Fill your container (it is better to choose a metal bucket, since plastic may not withstand the blows of the mixer) with water 1/3;
• Pour putty and stir the contents with a mixer. If you purchased a special drill for puttying, you can choose a whisk of any size. If you are using conventional drill, the whisk may be the smallest, otherwise the drill may burn out. To prevent the putty from splashing out of the bucket during mixing, switch the reverse to drills - this way the mixer will rotate counterclockwise.
• Stir the mixture to the consistency of thick sour cream. After that, let it stand for 5 minutes until all the lumps are completely soaked, and beat it again. Keep in mind that after this, the mixture can no longer be whipped, because its structure will be disturbed and the main properties - strength and quick adhesion - will disappear.

Mixing putty for drywall

When asked what kind of putty better fit for the ceiling, there is no definite answer: in fact, the products of different manufacturers differ a little, and for work on this particular part of the room, where a thin layer of the mixture is needed, any will do.

What is a primer and when is it needed?

Before proceeding directly to puttying, many recommend priming drywall.

There is always debate about this: do you need a primer at all? Someone says that without it the paint will not stick to the ceiling, someone that it will be impossible to re-paste the wallpaper later. Nevertheless, in general, everyone agrees that the primer has not harmed anyone yet, which means that it is better to spend a little time on this work than to regret later on not done.

Ceiling primer

There is also debate about when it is necessary to carry out a primer: before or after grouting. Most still agree that this should be done before processing the seams before puttying. Drywall sheets are primed with a brush-brush, letting them dry for about 3-4 hours, or even less, depending on the climatic conditions of the room.

We close the seams on the ceiling of plasterboard

When puttying the ceiling with your own hands, especially when working with drywall for the first time, special attention should be paid to the seams and their pre-treatment before applying the final mixture. First you need to inspect the screws with which the sheets are attached to the frame: the caps should go 0.5-1 mm deep, without tearing the cardboard, but not clinging to the spatula if they are held along the ceiling.

Installation of drywall on the frame

After checking these elements, feel free to start sealing the seams. This can be done using sickle and fugenfüller.

Serpyanka is an adhesive perforated tape that is easily attached to sheets. It must be applied at the place of the seams and puttied with a fugenfüller. He is construction material, with which the seams are filled, after diluting it to the consistency of thick sour cream.

The seams should dry for about a day. If you used tape, check the joints for protruding threads and remove them if necessary, otherwise they will cling to the spatula while puttying the plasterboard ceiling itself.

Corner work and final sanding

Filling drywall corner joints

If you are finishing a ceiling that has several levels or corners, or you want to process the junction of the ceiling and walls, you will need to additionally install metal corners.

In order to fix them, you must first treat the corner with the starting putty mixture, after checking the evenness of the end and preparing the corner of the desired length. Then press the corner into the putty, and smooth out the mixture that protrudes through the perforation with a spatula. You can add a little more putty and level it, while it is better to remove it from the very corner.

The angle must be even. Sometimes, for greater strength, a sickle is also applied to it, which is gently pressed into the uncured starting putty after attaching the corner.

After that, we can talk about the final putty of the entire ceiling. It should be noted that it is not necessary to apply the starting mixture on the GKL, since their surface already has a good level of adhesion. The ceiling is covered with a wide spatula, on which the putty is applied with a narrow spatula along the entire length.

The layer should be no more than 1-2 millimeters so that the weight of the sheets remains small. When carrying out such work for the first time, you can use the building rule to regulate the evenness of the surface (the putty that it removes can be thrown back into the bucket). To better understand how to putty plasterboard ceiling, you can watch the video.

Ceiling grinding

The last stage of work is carried out 5-7 days after the final drying of the ceiling.

Prior to this, you can slightly correct the evenness of the surface with a small spatula, but not earlier than the next day after applying the putty. The process of grinding with a grater with sandpaper (usually fine-grained) is called sanding. In the process of this work, you can use a spotlight on a tripod, illuminating the ceiling from different angles, in order to notice the smallest deviations and correct them, obtaining a perfectly flat surface.

In general, if you carefully and accurately follow the instructions, then the process is not difficult and it will not be difficult even for a beginner to putty a plasterboard ceiling.

However, each builder has his own secrets to help make the job easier or faster. Maybe you know those too? Tell us about them in the comments!

It is no coincidence that sheet gypsum board won the hearts of many craftsmen who make repairs. own apartment or at home with your own hands.

After all, working with this material, even for novice builders, usually does not cause difficulties. Except that finishing- plasterboard putty - not everyone can do it. But if you try, you can master this simple science.

It is necessary to putty plasterboard walls for subsequent painting and wallpapering

The surface of drywall structures can be finished as you like - stick wallpaper, paint, apply decorative plaster. But pre-puttying is required for any finish, so it is important to know how to putty drywall.

Plasterboard putty: video lesson

How to putty drywall

It is necessary to putty in drywall absolutely all seams, dents and joints, as well as mounting holes where the screw heads are located.

The primer starting putty is prepared immediately before use. The powder bought in the store is simply diluted with water in a certain proportion. You should prepare such an amount of putty that you can work out quickly enough.

The putty solution is mixed manually or mechanically - with a special drill with a mixer. The consistency is like thick cream.

The material is applied to drywall in a thin layer. If the layer is thick, the putty will crack after drying. Therefore, it is necessary to correctly putty drywall (and not only drywall, but also any wall) in stages: the next layer of putty is applied only after the previous one has dried.

On a plasterboard wall, only seams can be puttied, this will be enough

Now putty is produced not only in the form of powders, but also in the form of pastes. They are ready to use and can fill any bumps and holes in the drywall surface, even the smallest ones.

If you still have questions about how to putty drywall, you will find the video at the end of the article.

Drywall putty technology: step by step instructions

Step one: preparing the mixture for work

At 1.2 liters cold water pour out gradually no more than 2.5 kg of dry putty and stir it with a spatula or a construction mixer until the consistency of thick sour cream. You can check the quality of the mixture like this: if it does not slip from a spatula placed vertically, then it is suitable for puttying plasterboard walls and ceilings.

Step two: starting putty

Fill all joints, grooves and seams with putty. Move the spatula first across and then along the joints. When the putty dries, remove the bumps by sanding.

Puttying plasterboard walls is not fundamentally different from puttying other surfaces.

Step three: finishing putty

The finishing putty is mixed in the same way as the starting one. With a wide spatula, it is applied to all visible joints and recesses.

After puttying, the areas should be sanded with a grater with a grinding grid. It must be said that when puttying plasterboard walls or ceilings with finishing putty, work is carried out only when painting is planned. If thick wallpapers are glued to the walls or ceiling, as a rule, starting putty is enough.

How to putty drywall walls

A feature of plasterboard wall puttying is the need to process corners. For this, plastic protective corners are used. Putty should be applied evenly on both sides of the corner and the protective corner should be immediately fixed on it.

Try to crimp the edges of the corner with a uniform force. Excess squeezed putty is removed by transverse movements of the spatula from the edge of the corner, after which the mixture is evenly smoothed. After drying, the wall must be sanded.

When puttying plasterboard walls, special attention should be paid to the corners

How to putty plasterboard ceiling

The cut edge of the drywall sheet, which is adjacent to the wall, is recommended to be cut with a knife, cutting the edge at an angle of approximately 45 degrees. This sheet should be screwed at a distance of a few millimeters from the wall. Putty bursts the sheet and fixes it, which avoids the appearance of cracks in the corners.

Fill all cracks with a spatula, pressing the tool against the surface of the sheet. Stretch from time to time with a short rule for greater accuracy.

Plasterboard ceiling plastering is carried out according to the same principle as wall plastering.

After filling the joints on the plasterboard ceiling, proceed to sealing the screw holes. After that, the surface is pre-levelled. Prime all seams when the putty dries.

Banding before starting puttying - preparation of drywall for painting

The next stage of puttying the ceiling for painting is bandaging. A bandage tape made of paper or a fiberglass bandage is required.

It is glued on PVA. After wetting the paper tape, apply glue to the surface of the ceiling. Glue can be slightly diluted with water.

Glue the tape and pull it through with a spatula to squeeze out excess glue and any air bubbles. Remove excess glue and moisture with a sponge. If you use a fiberglass bandage, the procedure is similar, but you do not need to wet the bandage with water, but you should smear it again with glue after attaching the bandage to the ceiling.

Compliance with the basic simple rules of puttying will allow you to get a perfectly flat wall

It is best to glue paper tape into the corners, and overlap the transverse joints in the same way as the longitudinal ones. After that, the bandage is covered with a finishing putty. The layer should be about 1 mm.

For wallpaper, this is usually enough, but if a plasterboard ceiling is putty for painting, you need 2-3 layers of finishing putty. When it dries, the surface must be sanded and rubbed to remove small scratches and putty defects. You can use a grinder by connecting it to a vacuum cleaner.

Leveling the ceiling with putty

Trying to hide the defects of the base ceiling, we turn to suspended structures. At the same time, we also reduce the cost of repairing and decorating the ceiling surface. Of the variety of suspended structures, plasterboard ceilings are the most popular.

Moreover, the matter does not end with just the installation of sheets. Finishing is necessary, one of the stages of which is puttying. Therefore, let's take a closer look at how to putty a plasterboard ceiling.

What is required for work

Let's start with the tools. You will need:

• Construction mixer or drill with a special nozzle.
• A bucket, and preferably two - one for preparing a putty mortar, and the second for washing tools.
• Bucket small size for primer.
• Paint roller with foam coat.
• Two spatulas with a working surface length of 100 and 300 millimeters.
• Sanding synthetic mesh and grater.
• Sharp knife.
• Scraper.

From the materials you will need:

• Putty of two types - leveling (fugenfüller or uniflot) and finishing (satengips or "Shr-finish").
• Primer.
• Sickle ribbon.

Stages of putty plasterboard ceiling

First of all, we clean the room from everything that will interfere with the repair work. Be sure to cover the floor with plastic wrap or oilcloth.

You can also use old newspapers. One tip - in order not to breathe dust, try not to drop the putty mortar on the floor. If this does happen, remove it immediately.

Now pay attention to this nuance.

If there are joints on the ceiling (end or cut), they must be chamfered for filling with putty and a sample for sickle. To do this, you need to take a piece of sickle, attach it to the joint exactly in the middle and measure 5 millimeters in each direction from the tape. And draw parallel lines along these points along the junction.

Then you need to moisten the resulting strip with a joint in the middle with water so that the drywall is well saturated with it. Then, with a sharp knife, cut through the cardboard for the entire length of the lines with a recess of 1 millimeter into the body of the gypsum. Everything that remains in the strip must be removed to make a small groove.

Attention! If the screws fall into the groove field, then it is better to tighten them deeper using a regular screwdriver.

How to hold a spatula correctly

To remove cardboard and plaster, you can use a regular scraper, which is also easy to chamfer. After all the joints are prepared, you need to prime the ceiling surface. Especially the joints.

After that, you can prepare putty - fugenfüller or uniflot. Please note that this material cannot be kept in the air for a long time, so experts recommend preparing it in small portions.

To do this, water is poured into a clean bucket and the dry mixture is gradually poured into it, while the whole mass must be constantly mixed with a mixer.

You should get a homogeneous creamy mass. If it seemed liquid to you, then add a little dry mixture. If thick, then add water, but in both cases, you can not stop mixing.

Now we apply the finished solution to the chamfers, while it is impossible to clog the entire groove with them. At the same time, we putty the places where self-tapping screws enter the material. Pay attention to such a moment - the primer must be sure to dry.

And only after that you can apply putty. This is a prerequisite. The same applies to putty mortar.

After complete drying, the places with putty are rubbed with a grater.

Mounting the sickle tape

Processing seams in drywall constructions

The next stage is the laying of sickle, which is pre-cut along the length of the joint. Today, there are self-adhesive tapes on sale that are much more convenient to work with. They are glued to the joints and sealed with a putty mortar.

The solution must be pulled along the seam using a wide spatula. In this way, you can get rid of the influx of material. Be sure each putty layer must dry well.

Now apply primer. After it dries, again a layer of putty, which also needs to be dried.

After that, a grater with a grinding mesh comes into play. She sands the places where the putty solution is applied. This stage must be carried out carefully, without effort and sudden movements.

In this case, the finishing putty layer must be applied to the entire surface of the plasterboard ceiling. The fact is that drywall has bumps, no matter how hard you try to do everything according to the rules. Therefore, these defects need to be leveled.

To do this, use two spatulas at once. The smaller material is pulled out of the bucket and applied to the working surface of a larger spatula, stretching along its entire length. The solution is applied to the ceiling just by them.

Please note that putty must be applied along the drywall sheet.

The finished ceiling should look aesthetically pleasing

After that, remove all leveling material with the edge of the spatula. This will immediately show where there are recesses on the sheet - putty will remain in them.

And so on throughout the ceiling. And after the surface dries, it is necessary to apply another layer of putty material over the entire area of ​​\u200b\u200bthe ceiling. This is the final alignment.

Here's how to properly putty plasterboard ceiling. But experts assure that this is not the last procedure, because even professionals are not completely sure that the ceiling aligned in this way will be ideal.

How can this be checked?

You will need a regular light bulb. Bring it to the surface of the ceiling, and you will see all the defects and flaws - scratches, small drops, spatula marks, indentations, and so on. In order not to forget where they are located, mark these places with a pencil.

Then prepare some finishing solution, moisten the marked areas and apply a thin layer of putty. After the surface has dried, sand it and check the ceiling again with a light bulb. If the defects have not disappeared, repeat the operation.

Finished version of a two-level ceiling

And the final touch is the primer of the entire surface.

But keep in mind that you need to apply it strip by strip. You should not drive the roller in one place several times. This can damage the putty layer, which will get wet and begin to flake off the drywall.

It seems to be a simple process that a non-professional can handle. But the lack of information about some of the nuances can play a cruel joke.

And all the work will go down the drain. If someone didn’t immediately understand everything, you can watch a training video on how to putty a plasterboard ceiling - there is a video on our website. After all, it is better to see all this with your own eyes once than to listen a hundred times how and what to do.
