How to properly putty a wall for painting. How to properly putty walls for painting - a detailed description of the process

No repair can be imagined without putty work. Thanks to them, a completely flat surface is obtained for subsequent finishing. Today the most promising type finishing works is painting. And even most modern facing materials are made with the prospect of further coloring. Thanks to this, the interior of your apartment will always look unique. Therefore, puttying walls for painting should be done as perfectly as possible. When performing repairs yourself, you need to familiarize yourself with all the nuances of putty work.

A set of tools for performing work

To prepare and apply putty on the walls with your own hands you will need:

• dry putty;
• bucket for preparing the solution;
• poppet, for applying primer;
• construction mixer or hammer drill/drill with a whisk attachment;
• 3 metal spatulas: it is better to choose a wide one for applying the solution to the surface, a narrow one for supplying the solution, and a corner one for correct formation angle;
• reinforcing tape;
• grout block with mesh;
• cotton or rubber gloves;
• lamp for lighting.

How to prepare a surface for putty?

The technological process of puttingtying a wall for painting is no different from preparing it for wallpaper. But there is one important point: the wall or ceiling must be puttied very well, because even the slightest defects on the surface can be seen under the paint. The final result depends on how well the surface is puttied. painting works. Puttying the walls before painting hides all the unevenness, roughness and seams. It is necessary to putty before painting as regular ceiling, and suspended from plasterboard.

Do-it-yourself putty work must begin with dismantling the old coating. To do this, the surface is cleaned of whitewash, paint and possible irregularities on it. Old stains from dampness, fungus and rust are carefully treated. After removing old wallpaper, peeling putty may remain. It must be removed to avoid destroying the new putty.

Cracks in the ceiling and walls are repaired, primed and puttied. You can widen the crack using a spatula, making it wider.

After puttying, a special reinforcing tape is glued onto it to prevent the crack from appearing again in the future. The tape is puttied.

After the surfaces have completely dried, they are sanded using a trowel block with a mesh.

If the ceiling or walls have very large visible irregularities, they must be covered with sheets of plasterboard and also puttied.

How to apply finishing putty correctly?

After the surface has been leveled with the starting putty and it has dried, it is time to apply the finishing putty. It is diluted according to the instructions, mixed and applied in a thin layer of 1-2 mm to the wall using a wide spatula. Since all wall defects have already been removed with the starting mixture, applying the finishing mixture is much easier and faster.

In order to mix the solution, you need to dial Not a large number of water into a bucket, pour the dry mixture into it according to the instructions and use a mixer to stir the solution. Its consistency should be similar to medium thick sour cream.

The spatula should be held at an angle of 80°. This way the putty will lay down evenly, thinly and without streaks. After this, remove the remaining mass from the spatula and apply it again. A small putty knife can be useful for putting putty into corners or hard-to-reach places, such as behind pipes. To make the surface smoother, you can apply 2 layers of finishing putty.

When making repairs yourself, keep in mind that drywall is much easier to putty. It is enough to fill the seams and dowel holes with starting putty, wait for it to dry and the surface is ready for applying a base for painting.

Once everything is completely dry, you can start sanding the surface using a fine-grit grout block. Do not press too hard on the block to avoid scratching the putty. Stock up on a respirator or gauze bandage, special plastic goggles and put on a hat. When grouting, a large amount of dust is formed, which gets into the eyes and respiratory tract of a person.

After the walls and ceiling have been sanded, you need to take a high-power lamp and carefully examine the entire surface for possible missed irregularities. If there are any, clean them. Then you should take a duster or soft cloth and wipe off the dust from the surface. If you do not do this, when priming, visible drips from the primer and pellets may form. After priming the walls and ceiling, let them dry for 2-3 hours and you can start painting.

A little about finishing putty

All putties for painting contain modifying components. They make the mass pliable and more plastic.

If you are making repairs with your own hands and you are faced with the question of which putty to choose, familiarize yourself with the qualities that a good dry mixture should have:

• it should be easily applied to the starting base, not reach for the spatula and lie down without the formation of lumps;
• when applied in a layer of no more than 3 mm, no defects in the starting putty should be visible;
• the putty should not flow down the wall;
• after drying, cracks and cavities should not form;
• The color of the putty wall should be an even shade of white.

When choosing a dry mixture, you should also take into account the hygroscopicity of the mixture. If you plan to apply the mixture on non- flat surface, it should be primed. Please note that gypsum does not tolerate moisture.

For an inexperienced person, the whole process may seem complicated, but as soon as you get started, you will immediately realize that you can easily do the repair yourself.

In the kitchen, interior renovation is required more often than in other rooms. Usually it is enough to re-paste the wallpaper yourself or paint the walls. This article covers the subtleties of finishing technology in the kitchen. A video to help a beginner will tell you how to properly putty walls for wallpaper or painting.

Wall putty - is it possible to do without it?

Are the walls in your kitchen worn out and cracked? Is your wallpaper covered in oil stains? No wonder! The kitchen is a room where the interior often needs to be updated. In order to carry out repair work correctly, you must follow some rules.

Wall repair includes three stages of preparatory and repair work:

1. Preparation of wall surfaces - at this stage it is necessary to thoroughly clean the walls of old wallpaper, glue, layers of paint and crumbling plaster.
2. Rough finishing of walls - careful alignment kitchen walls, sealing irregularities with plaster, as well as reinforcement (if necessary).
3. Finishing the walls is the final stage of wall finishing, which includes puttying, painting or.

When performing repair work on your own, the rough preparation of the walls is often not carried out or is carried out in places. Neglect of leveling and plastering the walls will affect the overall quality of the completed repair: the paint lays unevenly on an unprepared surface, burrs are visible on the surface, and “bubbles” may form under the wallpaper.

Applying a layer of plaster to the walls reduces the number of cracks and scratches, and reliably smoothes out plaster sagging. And leveling the surface of the walls with putty helps to get perfect surface, fine finishing which poses absolutely no difficulties.

Wall putty technology: preparing the base

The technology for applying putty to walls for painting and wallpapering has significant differences. The process of applying the working composition to the walls has its own techniques and methods. Preparation of putty also has its own characteristics.

To prepare putty, it is best to use ready-made dry mixtures, which are offered in abundance by modern manufacturers. Before purchasing a dry mixture, you must carefully familiarize yourself with the recipe for preparing the mixture and the consumption rates per 1 m2.

Advice! It is very important to strictly follow the putty preparation recipe in accordance with the manufacturer’s recommendations. A properly prepared mixture will ensure a more even smoothing of the layer and better adhesion to the wall surface.

It is important to remember that the layer of putty applied to the wall under the wallpaper should not exceed 2 mm in thickness. Preliminary preparation walls should be done especially carefully. Small cracks and scratches must be repaired; deep potholes must first be cleared and then carefully filled with plaster. Sometimes there are deposits of old on the walls plaster mortar, such places must be thoroughly cleaned, knocking down protruding parts.

Special Requirement for Removal old whitewash– the walls should be cleaned completely. Ideally, wash it and then let it dry.

Important! Putty applied over old lime is not durable. Wallpaper that is heavy, especially vinyl and non-woven wallpaper, will not hold up on poorly treated walls.

Applying primer

After removing the old coating from the kitchen walls, you need to treat the surface with a stiff metal brush - this operation will remove the maximum amount of dirt. After cleaning the walls with a brush, you can begin applying the primer. This is done only if the wall is relatively flat. If there are significant curvatures, you should first correct the curvature of the walls with plaster.

It is convenient to use a roller to apply the primer, thus easily achieving uniform distribution of the primer over the wall. The primer composition can be purchased ready-made; you can always find the primer on sale in the required packaging.

Advice! It is difficult to use a roller in the corners of a room. For better application of primer in corners, use a narrow brush with long, stiff bristles.

After applying the primer, dry the walls thoroughly. Do not apply putty to a wet surface. When applying putty on plasterboard walls that have a smooth and even surface, it is enough to apply one layer of putty, which will be the finishing layer. Old, plastered surfaces are smoothed with plaster until absolutely smooth.

You can find out how to putty the surface under wallpaper in the video for this article.

How to properly putty walls before painting

Special actions for applying putty for subsequent painting of walls should be considered multilayer (it will not be possible to get by with just one layer). Sometimes on particularly problematic walls it may be necessary to glue a layer of painting mesh, which is alternately covered with several layers plaster mixture followed by grinding. and only then putty is applied.

Attention! It is important to purchase only high-quality tools for the job. The spatula must have an absolutely smooth blade without nicks or scratches.

Manufacturers produce a variety of mixtures for wall putty. The consumption of raw materials per 1 m2 can vary significantly:

• Oil-adhesive putty – consumption 3.0 kg/m2.
• Adhesive compositions – consumption 0.47 kg/m2.
• Gypsum plaster - consumption 0.85 kg/m2.
• Finishing putty - composition consumption 0.44 kg/m2.

Here are the average rates of material consumption, provided perfect condition walls

From the possible types of putty, choose the one that suits you

As when preparing walls for wallpapering, walls to be painted before applying plaster must be carefully prepared: remove old paint or wallpaper, repulse the plaster composition, clean deep cracks.

Important! All wooden plugs, nails, screws and other fasteners should be removed from the walls. Holes in the wall must be sealed with cement mortar. The same composition is used to fill old holes for wiring, deep cracks and potholes.

Cleaning the walls continues with a wire brush, after which you can begin applying primer. Application of putty is allowed no earlier than 24 hours after the primer layer has dried.

It is convenient to start applying the composition from the right corner of the wall. It is worth monitoring the thickness of the applied layer - it should not exceed 2 mm.

Do not be upset if the first layer of putty is not ideal; re-application of the composition will correct the situation. It is important not to start applying the second layer of putty until the first layer has set. This will take about 12 hours.

Ideally even corners are made using a special tool - an angle spatula. It is worth ensuring that the thickness of the applied layer in the corners does not exceed 5 mm.

The most optimal and inexpensive way to finish walls is painting. However, paint must be applied to a prepared surface. And this needs to be done efficiently, since after painting all the flaws and irregularities will be visible. We will try to analyze the question of how to putty walls for painting in this article.

Putty comes in two main types:

• For interior works,
• For external works.

It is unacceptable to use putty for external work inside a building, as it releases toxins that are dangerous to human health. Putty for interior work is also not suitable for exterior work, as it is easily destroyed under the influence of moisture and temperature changes.

The components are divided into:

1. Cement putty– used when puttingtying facades or in rooms with high moisture.

2. Gypsum putty - has a beautiful White color, used as the final stage of wall finishing. Not suitable for rooms with high humidity.

3. Polymer putty, which has subtypes:

• acrylic putty – is versatile. Scope of use: internal, external finishing, as both starting and finishing putty,
• latex putty – used for interior decoration. It is flexible and easy to work with.

According to the stages of work when finishing walls, putty is divided into:

• starting putty, which is used to level out all the unevenness of the walls. Has a rough base due to the sand content,
• finishing putty, which is used at the final stage of finishing. It has a granular structure that provides a perfectly smooth surface,
• universal putty - suitable for both the initial and final stages of work.

Tools for puttying walls for painting:

• spatula 60*80, 20*25,
• nylon mesh, mesh size 0.2 cm,
• sandpaper or sanding block,
• abrasive mesh 60,80, 120,
• bubble level,
• container for diluting putty,
• metal beacons,
• construction mixer,
• roller, brush.

Materials for preparing walls for painting:

• finishing putty,
• starting putty,
• primer,
• water,
• cement mortar.

Work on leveling the walls

The first stage of work is leveling the walls. To do this, we remove all existing coverings from the walls. By using sandpaper or a sanding block we grind the surface. We check the evenness with a level. The maximum difference should be 0.5 cm. After this, we prime the wall and wait for it to dry completely.

If sanding fails to remove wall unevenness, there are two options:

• finishing walls with plasterboard,
• complete plastering of walls.

If the difference is more than 5 mm, we install beacons and level the wall using isogypsum or cement mortar. To hide gross surface defects, sometimes a layer of about 3-5 cm is applied. Before this, the starting putty is mixed with well-sifted sand. Ratio 1:1.

When the work of leveling the walls is completed, use a roller or brush to apply a layer of primer to the walls. This will help get rid of fungi and microorganisms, and the putty will attach more securely to the wall. Primer drying time is 4-5 hours.

How to prepare the putty mixture:

1. Prepare a bucket of water and putty.

2. Read the instructions; the proportions of water and dry mixture are indicated there.

3. Dilute a small amount of putty mixture, as the putty hardens very quickly and will make it more difficult to work. Optimal time use putty for 30-40 minutes.

4. Be sure to pour the putty into a bucket and then fill it with water.

5. Stir the mixture with a mixer and leave for 5-10 minutes for swelling.

6. Mix again for 3-4 minutes.

7. We do this three or four times.

8. The mass should be free of lumps and have an elastic structure.

Starting putty is always sold dry, but finishing putty does not need to be diluted with water. Since there are many types of long-lasting finishing putty, which are sold ready-made. This putty is more convenient and does not harden during work.

Applying starting putty to the walls

To apply the starting putty we use two spatulas. With the large one we apply the putty on the walls, and with the small one we distribute the putty over the surface of the large spatula. Distribute the putty evenly for easier application.

When applying putty from left to right, top part the spatula is located to the right than the bottom one. Hold the spatula at an angle of 45-6°.

It is better to apply the starting putty in several layers, waiting until the previous layer has completely dried. The optimal layer for applying starting putty is 3-4 mm.

To prevent cracks from appearing in the wall, use a nylon net with a mesh size of 0.2-0.5 cm. Apply a layer of putty to the wall and attach the mesh to it, then apply a second layer to the mesh and spread the putty over the surface. The thickness of the layers is 1-2 mm.

Experienced painters replace the mesh with fiberglass or glass wallpaper, which are sold complete with special glue. After finishing with glass wallpaper, painting is possible, but in this case you will need 2-3 times more paint than after finishing with finishing putty.

Use coarse sandpaper to sand the surface. Fine grains on the surface after applying the starting putty are the norm, because such putty is coarser than the finishing putty.

Finishing putty - application features

The next stage of finishing is applying finishing putty to the walls. The layer of finishing putty is much thinner than the starting putty. Before applying, read the instructions, it should indicate the maximum layer of finishing putty.

The final putty of walls for painting is applied in several stages, and after the surface has completely dried, it is sanded with an abrasive mesh, 60 or 80 grit. When sanding, do not overdo it, so as not to scratch off the entire layer of putty. Use a level to check the evenness of the walls.

How to check walls for unevenness

After completing the putty work, you need to make sure that the walls are completely ready for painting. Since when painting, all small irregularities and roughness will be visible.

Take table lamp or a spotlight, tilt it towards the wall at an oblique angle; if small defects are visible, you should get rid of them using grinder or a hand block.

Primer is the final stage of preparing walls for painting.

At the end of the putty work, after the last layer of putty has dried, you need to get rid of small particles of putty and dust. To do this, use a dry cloth or vacuum cleaner. Before painting, the walls are treated with a primer.

Technology for preparing plasterboard walls for painting

The process of applying putty to a plasterboard wall is much simpler. To do this you need to perform a number of actions:

1. Apply primer over the entire surface plasterboard walls. Under no circumstances should alkyd primers be used, as plasterboard will be deformed. The thickness of the primer layer is 0.02 mm.

2. Prepare the wall. Inspect the joints of the drywall and how the screws are screwed on.

3. Glue a special fiberglass mesh over the joints plasterboard sheets so that the seam is in the middle of the tape.

4. We putty the joints. To do this, prepare two spatulas 12-15 and 30-35 cm.

6. Alignment of corners. Putty one side of the corner, and after drying, the other.

7. After all joints and corners have dried, attach metal corners on window or door openings.

8. Putty the entire surface. By using small spatula press the putty into the profile holes. A wide spatula will help level the putty on the surface.

9. To apply putty to the arch, use a special plastic corner. Secure the corner with a stapler.

10. Since this corner is thicker than ordinary aluminum, the putty is applied twice.

11. After drying, sand down any uneven surfaces.

12. The next stage is applying the finishing putty. The putty should be applied in a very thin layer using a wide spatula.

13. After the finishing putty has dried, prime the wall.

Tips for puttingtying walls before painting:

• never apply the finishing layer of putty until the starting layer is completely dry,
• The approximate calculation of putty is as follows: for 1 m² about 1200 g of dry putty,
• when choosing a primer, focus on deeply penetrating types that are resistant to temperature changes,
• primer consumption per 1 m² is about 80-100 g,
• the maximum layer thickness should not exceed 4 mm,
• for applying putty on internal corners use a rule and a wide spatula,
• the durability and strength of the walls depends on the quality of the putty,
• When preparing the putty mixture, focus on the consistency of thick sour cream. Since a very liquid mixture will slide off the spatula, and a too thick mixture is difficult to work with,
• The putties are of excellent quality: Ceresit, Triora, Polimin, Saten, Knauf,
• when diluting dry putty, use a respirator,
• apply putty in different directions: horizontally, vertically and diagonally,
• Never try to dilute thickened putty with water. Thus, the quality of the putty surface deteriorates,
• For large surfaces use a large spatula, and for corners or hard to reach places A smaller spatula will do,
• It is best to choose a spatula made of stainless steel,
• It is possible to use an expander gun to apply the putty mixture. In this case, use a rubber spatula to smooth out the putty.
• When finishing work, wash the tool immediately, as it will be difficult to do this later,
• For the first three days after completion of work, protect the room from moisture, hypothermia or too high temperatures.

If the process of applying putty seems very difficult, it is better to trust the professionals. After all, if you do not properly prepare the walls for painting, you will have to redo everything all over again, which means a double waste of materials, money and time. For puttying walls for painting, prices vary, it all depends on the area and quality of the walls. One square meter putty for painting on a concrete wall costs about $8, on a plasterboard wall – $6.

You can avoid puttingtying the walls during repairs only if you decide to cover them with decorative materials. wall panels or tiles. Other types of finishing require preliminary finishing leveling, even if the base is made of plasterboard, glass magnesium sheets and others sheet materials.
It is prepared especially carefully for painting, since this type decorative finishing able to reveal all the flaws made during alignment. Therefore, the question of how to putty walls for painting is far from idle.

If this job were as simple as mopping floors, for example, then no one would even think about searching good specialists by finishing. But both the process itself and preparation for it involve significant physical effort and require certain knowledge.
Therefore, even if the main repairs are done with your own hands, craftsmen are usually invited for “wet” work.

This is the most correct option, if you do not have enough experience. Putty is not the cheapest material, you need quite a lot of it, and it would be a shame if the price you paid for it was lost due to your incompetence and “crookedness.”
But don’t give up if you have no other choice but to putty the walls yourself. We will try to describe this process in as much detail as possible so that you do not have any difficulties when choosing materials and determining the sequence of work. And the video in this article will help you better understand the technology of applying putty.

Preparing the walls for putty

Algorithm preparatory work depends on the condition of your walls.
Carefully examine their surface:

• If the base is uneven, it should be leveled with plaster before puttying;
• If there is some old coating on it that does not hold firmly and is crumbling (plaster, paint, varnish, etc.), it will have to be removed;
• If there are cracks on the surface, they need to be puttied separately before treating the entire area.

A separate story is walls lined with plasterboard or other sheet materials. Make sure that no self-tapping screw protrudes beyond the plane of the surface by running a clean spatula over the heads. Screw the protruding hardware deeper using a screwdriver or screwdriver.
The next mandatory step, which is required by the instructions, is priming the surface (see Primer for drywall - why is it needed). It is produced in any case, regardless of the material and strength of the base, but the primer is selected in accordance with these factors.
The purpose of the primer is to strengthen crumbling surfaces, protect them from moisture absorption, remove dust, and improve adhesion with the applied putty solution.

Advice. From the right choice The quality of subsequent work depends on the primer. Carefully read the information on the purpose of the compositions on the packaging, take into account not only the material of the walls, but also the climatic conditions in which they will be used.

The primer is applied with a brush or roller; it is also possible to use a spray bottle.
If plastered or concrete walls are primed entirely at once, then plasterboard walls are treated differently. First, only the joints between the sheets are processed, and after they are sealed, the entire surface is treated. But more on that later.
You can start puttingty directly after the primer layer has completely dried.

Choosing putty

Conventionally, putties are divided into two types:

• Starter – coarse-grained, intended for initial leveling of surfaces with minor defects– cracks, depressions, etc.
• Finishing – fine-grained, intended for final leveling and making the walls smooth.

When deciding how to putty the walls for painting, keep in mind that this is done in at least two layers. Therefore, the first layer can be the starting layer, the second – the finishing layer. The exception, again, is plasterboard walls: after sealing the seams, it is enough to putty them once with the finishing compound.

Note. Each layer is primed again after drying.

There are two types of putty on sale: ready-to-use and a dry mixture that requires dilution with water:

• Ready-made formulations are supplied in plastic buckets of various sizes. They have an optimal consistency, do not require time to prepare, are easy to apply, but are more expensive than dry mixtures.
• Dry putties are sold in paper bags. To prepare the working solution, you need a special tool - a construction mixer or a drill with a special attachment. It is very difficult to manually mix the putty until it is homogeneous.

Take this information into account when choosing a leveling mixture. As for the tools, their set is small: you only need a few spatulas different widths and a construction float with sanding mesh or fine-grained sandpaper.

We level the walls

If you use a dry mixture, you need to apply it immediately after preparation, since the shelf life of the working solution is no more than an hour. Therefore, you need to knead it as much as you have time to use during this time.
The technology for puttingtying walls for painting is simple, but requires great care and attention. Let's start, however, with a description of the sealing of joints (for gypsum plasterboard or LSU).
So:

• After the primer has dried (see Types of construction primers and their area of ​​application), applied to the contact points of adjacent sheets, the seams are coated with putty using a wide spatula;

• While the solution is fresh, sickle tape is glued to it along the entire seam. It is pressed into the putty with a narrow spatula and smoothed so that the solution protrudes through the mesh cells;
• After this, another layer of putty is applied to the seam, which should completely hide the sickle and level the recess between the sheets created by the factory edges.

At the same time as the joints, the screw heads recessed into the plasterboard are also puttied. This is done literally with one movement of the spatula.

Wait for the seams to dry and sand them with a float. Then prime the entire surface of the walls. Again, wait 3-4 hours (or whatever the primer manufacturer recommends) before starting the main job.
In general, this is a long process precisely because of the need to withstand a technological break between all stages: primer, layers of putty (see Decorative putty as a finishing wall finish). But you cannot neglect it - the quality will suffer.
Puttying itself is done as follows:

• Using a small spatula, take a small amount of solution from the container and transfer it with a sliding movement onto a wide working spatula, distributing it evenly over it;
• It is brought to the wall at an angle of 20-30 degrees and moved along the surface with uniform pressure diagonally;

• The next movement is made in a cross direction;
• Having used up the entire portion of putty from the spatula, pick up the next one and continue working so that the solution overlaps the already applied area. To do this, move the spatula towards this area, and not away from it;
• Try to make the layer not thick, no more than 2-4 mm, and do not leave grooves on the surface from the edges of the spatula - immediately level them;
• Pay special attention to the corners. To make them smooth and straight, use a special corner spatula or secure corner plaster profiles in them before starting work;

• Wait for this layer to dry and remove visible blemishes by sanding;
• Prime the surface again and apply a final leveling layer of putty, the thickness of which should not exceed 1-2 mm. To do this, make the solution a little more liquid than the first time;

Note. Smooth walls from sheet materials, it is enough to putty once after sealing the joints - immediately clean.

• The final stage is polishing with backlight. Sand the walls, directing a beam of light at a slight angle to the area being treated. It will help to identify the slightest defects that may not be noticeable on the putty, but will appear after painting.

Before painting, it is advisable to prime the surface again so that the paint does not absorb into the base and adheres well to it.

Conclusion

Now you know how to putty walls for painting with your own hands, but in theory. To do this work efficiently, without defects, it would be a good idea to watch the work of specialists and practice on an inconspicuous section of the wall. We are sure that everything will work out for you, good luck with your repair!

Despite the diversity finishing materials, painting walls is still relevant. Some are attracted by the simplicity of such finishing, availability of materials and low price, while others are attracted by the opportunity to do everything themselves, without specific construction knowledge. To bring the bases into proper shape, you can use putty on the walls yourself, and this method is suitable for both painting and wallpaper.

When can you get by with putty only?

The question is quite reasonable, especially for owners of old apartments, where the evenness of corners and walls sometimes causes fits of laughter. Putty is relevant in several cases:

• High quality old plaster or minimal voids.
• A slight difference in level.

If both conditions are met, wall putty will bring its positive results. When Bad quality old plaster coating (when tapping you find many voids), this option is eliminated. The same applies to large differences in level (over two centimeters).

Puttying the walls for painting is the final stage of leveling the base with your own hands. It cannot perform the functions of full-fledged plaster, since it is intended only for final leveling.

What types of putties are there?

Type binder putties can be divided into several groups:

• Gypsum cement.

They are sold in the form of dry mixtures. Dissolve them in water. The kneading technology must be strictly followed. The mixture is poured into water, but not vice versa. They are further divided into three groups, designated by the following markings: KR, LR are used in residential areas, VH in wet areas.

• Water-dispersed.

The base is gypsum and cement, but the mixing is done in a factory. For mixing, not water is used, but a water-polymer emulsion. Sold in buckets and ready to use immediately. They have excellent, uniform viscosity, are easy to rub in with your own hands, are durable, and give a high-quality smooth surface. They are more expensive than dry mixtures. Using these finishing putties on walls will perfectly prepare them for painting.

• Acrylic.

Such putties provide a perfectly smooth surface, but cheap paint does not adhere well to them. For getting good result Buy only high quality products.

• Oil-glue.

An old-fashioned option that is not suitable for modern foundations - brick, concrete, plastered. The drying oil on which it is made is perfectly absorbed, and then easily shows through any paint (the only exception is oil paint), whitewash, and wallpaper.

On a note. Puttying cannot be done concrete walls with this composition if you plan to use them for painting in the future.

Oil-adhesive putty, however, can be successfully used in bathrooms and kitchens, under tiles. Wooden walls It is recommended to treat only with this type of putty ( wooden shingles), it protects any base from rotting and has waterproofing properties.

Types of putties according to the order of work - universal, starting and finishing. And now a little more detail about which ones are needed for what and how to work with them.

• Universal. Produced using polymer binders, sold in buckets (opened and started). But it loses its qualities when improper storage. It can be used for both starting and finishing puttying. The surface is of very high quality.
• Starting or leveling. It can be applied up to one and a half centimeters thick. You need to select them according to the type of walls. Puttying concrete foundations made with your own hands, for example, with a mixture of Ceresit.
• Finishing putty is required if further finishing is thin wallpaper or paint. It has a fine-grained structure and rubs well. Placed thin layers until the last scratch disappears. If you are planning to decorate a room vinyl wallpaper, panels or tiles, then produce this type no work needed.

To prepare walls for painting, you can use all of the above types of putties. Ready-made universal is more expensive than the other two, but there are no problems with preparation. Just opened the bucket and put it aside required quantity and you work. Just don’t forget to close it again, otherwise the composition will begin to dry out and lose its properties.

Manufacturers of putties

The Weber company produces one of the popular putties Betonit. Not the best good option for work, as it adheres weakly to any surface. However, it can be used for painting, but only in dry rooms with stable temperature conditions.

On a note. If you apply a small layer of stronger putty on top of Betonite, you won’t get anything special. In addition, Betonite has poor adhesion to everything except itself. Therefore, it is better to buy another mixture, a little more expensive, but much better at adhering to the walls.

Putties from Knauf are not as economical as Betonit, but they can be used both for painting and for wallpaper. They differ high quality and excellent adhesion. Prominent representatives rulers - Uniflot or Fugagips.

Another manufacturer is Yunis. Its compositions are strikingly white and fit perfectly under painting.

Ceresit produces putties for concrete foundations. This is a German brand, but the products are manufactured in Russia.

Preparing the base

If you decide to do everything yourself, then let's start by preparing the walls. If you plan to hire professionals for putty work, you can also prepare the base yourself. But remember, the price of puttying by the hands of professionals is almost equal plastering work. Therefore, there is a great reason to do everything yourself.

Step 1. Strip off the wallpaper or paint.
Step 2. Tap the old plaster.
Step 3. If there are voids, we knock down the detected areas, clean the walls of dust and prime them. Then you can start working with putty.
Step 4. If there are a lot of voids or the plaster barely holds on, then remove it completely.
Step 5. Clean the walls from dust and dirt, and inspect for oil stains. If you find them, wash them off with solvents.
Step 6. Prime the surface.

On a note. The technology used to putty concrete bases with your own hands includes the mandatory use of a special primer. It should include quartz sand. After treatment, the concrete becomes rough, which increases adhesion. For smooth concrete walls this best option, allowing the use of putties with a high cement content.

Working with putty

The technology used for final leveling of walls for painting includes two stages - applying a leveling layer (starting putty) and a finishing layer (finishing putty). If you are going to work with a universal composition, then you also work in two stages.

Why will we plaster in two stages just before painting? The answer is simple, this option for decorative wall decoration is the most picky about the quality of the base. If for application decorative plaster, for paneling or tiles If its perfect evenness is not important, this moment is very important for paint. Finishing putty helps make the wall as smooth as an egg.

The technology for leveling walls with putty for painting requires the following simple rules:

• Preparation of starting putty solution.
• Puttying holes, cracks or joints (if we are dealing with drywall).
• Applying a leveling layer.
• 24 hours for the walls to dry.
• Prime and dry again for a few hours.
• Using a carrying lamp, you need to inspect the entire surface of the walls, identify scratches and small holes.
• Preparation of the finishing solution and elimination of remaining defects.
• Smoothing the surface. If no more irregularities are found, then the final layer of finishing putty is applied.
• After it dries, we treat the surface with very fine sandpaper for final sanding.

The technology for making homemade putty is quite simple. Gypsum, chalk and wood glue are combined with your own hands in the following proportions: 1/2/2. First, sift the chalk and plaster, then mix them thoroughly and add them to the container with glue. Mix everything with a construction mixer. But to achieve best result It is better to use either ready-made putty or a dry mixture purchased in a store.

Plastering walls for painting - important stage in repair and construction. It is not needed for laying tiles or decorating panels. But thin wallpaper and paint cannot do without putty work, which will make the walls perfectly smooth, without a single scratch. In the video below you can see how this happens.
