Which putty is best for walls to be painted? The preparation of the walls affects the quality of their finishing. After plastering, quite large particles remain on the surface of the wall, which must be thoroughly wiped off before painting or wallpapering. For final leveling of surfaces, putty is used.

The article will tell you how to do it yourself correctly.

It doesn’t really matter how much it costs to putty walls for painting; all compositions for leveling surfaces are conditionally intended for:

• Work indoors.
• External works.

In addition, both types of putty are divided into three main groups according to their physical and mechanical properties and method of application:

• Starting putty. It has a rough structure consisting of large elements of mineral filler. The material is designed to smooth out large defects on walls and correct existing geometric deviations of surfaces. The layer of starting putty can reach 20 millimeters. The solution has a thicker consistency and is rougher.
• Finishing putty. It has a fine-grained structure. After the material has dried, you can get a perfectly flat and very smooth surface. It is applied with starting putty directly onto a previously untreated wall, and is a good base for covering walls with any paint and varnish coatings.
• Universal putty. It goes on sale in a ready-to-use form; it has the consistency of a thick, finely dispersed composition on a polymer base, used as a starting and finishing leveling solution.

Advice: When answering the question: what putty to choose for walls for painting, for beginners, preference should be given to a universal mixture that does not require independent preparation, and dries to form a smooth and fairly even surface of good quality.

Depending on the degree of readiness, the types of wall putty for painting are:

• Dry. These are special formulations that are prepared immediately before application. Such products are produced in bags and packages.

In order to mix it correctly, the instructions must be strictly followed (see How to dilute putty when doing your own repairs). Advantages of this product:

1. low price;
2. good quality of the composition, when used correctly.

Advice: The prepared mixture should be used for a limited time so that it does not have time to lose its properties.

• Ready to use. This putty for walls for painting is more convenient to use. It is packaged in a special container; it does not require time for preparation or strict adherence to technology.

The components have the required proportions and are ready for work. The finished solution remains usable for a long time, without changing its characteristics. During breaks in work, close the container tightly with a lid.

Depending on the type of main ingredient taken in their manufacture, the materials can be:

• Plaster(see Gypsum putty: its advantages and problems of use). Their advantages:

1. align well;
2. do not shrink.

Flaw:

1. poor resistance to moisture, which limits their use.

Such materials are used in dry rooms, and their use outside the house is not recommended. After drying, the surface becomes white, which is especially important for the bedroom and living room.

• Cement. The peculiarity of the material is its high resistance to moisture. But:

1. the mixtures shrink;
2. When dry, the walls become gray in color, which will be noticeable through white paint or thin wallpaper.

• Polymer. Such solutions allow you to finish walls of the highest quality. This is due to the presence of high-tech modern components in the composition. Its cost is significantly higher than other types of material. They are recommended for finishing walls.

How to putty before painting a wall

You can do the putty yourself or hire specialists. It is necessary to take into account that the cost of puttying walls for painting depends on many factors.

These include:

• Dimensions of processed surfaces.
• Preliminary preparation of walls.
• Number of corners in the room.
• The thickness of the irregularities.
• Type and complexity of putty.
• The number of layers of solution applied.

The cost of putty will be higher for further painting of the room than finishing the walls with wallpaper.

The technology for performing putty in the bathroom before decorative finishing is as follows:

• Before plastering walls for painting, it is necessary to inspect them for the presence of fungus and mold and eliminate defects.
• Remove old coating. This can be done:

1. using special solutions;
2. using sandpaper;
3. scraper;
4. grinder with a flexible disk.

Tip: The best way to remove old coating is to use a special diamond grinding system. In this case, the old paint is removed quickly enough, and the wall surface remains undamaged.

• If various defects are detected: cracks, irregularities, they are removed. Large protrusions are removed with a sharp, durable spatula or plane. To get rid of cracks, they must first be widened and then cleaned to a solid layer of material.

• The prepared depressions are rubbed using a medium or wide spatula. Application of the solution is carried out with sweeping, crosswise movements, with medium pressure on the tool.
• Mandatory conditions for using the solution in the bathroom:

1. its moisture resistance;
2. the composition must be intended for carrying out internal work.

The best choice for this are putties made on the basis of latex or acrylic (see Acrylic putty - types, features, application).

• The material is applied to the wall with an overlap. To obtain an even layer with a thickness of 2 to 4 millimeters, it is necessary to properly maintain the pressure of the tool. Apply the solution in several layers until the surface base is brought into one plane.
• When drying walls, it is necessary to exclude the presence of drafts in the room, and if there is a window in the bathroom, direct rays of the sun should not fall on the finished surfaces. Do not direct heat from a fan onto them. The drying period for the compositions is indicated on the instructions supplied with them. On average, 12 hours is enough, but work should be continued no earlier than after 24 hours.
• An abrasive jointer is used to remove the deposits formed after the solution has hardened. The flatness of the surface is controlled. To do this, use a flashlight and a rule.

Putty for painting has some features:

• After bringing the surface to zero, and then rubbing it with an abrasive, a finishing layer is applied, which is rubbed with 150 sandpaper, as shown in the photo.

• To obtain a surface for mirror painting, it should be additionally polished with a plaster trowel with suede.

Tip: You cannot use felt or felt for polishing, and if suede has been used previously, it must be replaced with a new one.

• When painting walls with water-based paint, it is necessary to prime the surface, most often according to the instructions in three layers. At the same time, it is desirable that the composition contains antibacterial additives, which will protect the walls from the appearance of mold and mildew on them.
• For the application of glossy water-based paints, the requirements for surface preparation are more stringent than for matte paints.

How to putty gypsum boards before painting, if desired, can be seen in the video in this article. When performing putty on walls for painting, the main condition is to adhere to all instructions and recommendations of specialists attached to the materials.

Painting has always been considered the simplest and most affordable option for finishing rooms. It was valued for its speed and simplicity. However, it is important to keep a few things in mind before you get started. Paintwork material is not able to hide surface imperfections. This means that the wall must be perfectly flat.

One way to achieve this is to putty the walls before painting. The process is not complicated, but it requires certain knowledge and sequence of work. The good news is that there is a large selection of products for puttying, and the tools are affordable and simple. Let's look at how to do everything correctly and quickly.

Choice of putty

The construction market can provide many varieties of mixtures. According to the scope of use, they are divided into two categories: facade (for external work) and internal. According to functionality and purpose, putty can be starting and finishing.

The starting one, also called the base one, allows you to eliminate all surface imperfections and is used for rough work. However, painting the room is allowed only when the final puttying of the walls has been carried out. The layer is applied on top of the start; it is thinner, more even and beautiful. The finished result will depend on the quality of the finishing coating.

If we consider the composition of the putty, it is divided into 3 main types:

1. Cement-based composition.
2. Gypsum-based putty.
3. Polymer based.

Each of the materials has its own advantages and materials, as well as scope of use. This must be taken into account before choosing wall material for painting. For example, cement compositions are not afraid of moisture, they are strong and reliable. They can be used in the bathroom, kitchen and outside. However, they are not suitable for painting, only for laying tiles.

As for children's rooms, safety and environmental friendliness are important here. Gypsum mixtures are afraid of moisture, so they are not suitable for rooms with high humidity. The best option is to use acrylic putty. It is protected from moisture and is suitable for painting. This is a universal composition.

If you need to putty the gypsum board walls, then special attention is paid to the joints and screw caps. They are treated with gypsum mixtures or special grout. Additionally, the joint is treated with a serpyanka mesh.

The most famous brands are:

• Knauff;
• Ceresit;
• Rotband;
• Fugenfuller.

Polymer materials are those made on the basis of polymer additives: acrylic, latex. Their advantage is that they are sold ready-made; they do not need to be kneaded, which speeds up the work process. The cost of production is higher than gypsum and cement.

Gypsum putty is a good choice for painting. It is inexpensive and has good characteristics. But if the room is damp, then you need to choose polymer compounds. You will have to pay extra, however, the puttying of the walls will not be done in vain.

Important! Gypsum putty is hygroscopic and absorbs moisture. Therefore, after purchase, before you putty the walls for painting, you need to store it in a dry place.

Leveling and preparing walls

To get perfectly smooth walls with high-quality painting, you need to carefully prepare the base. The whole process consists of the following steps:

1. Removing old finishing material from the surface.
2. Cleaning walls from dust and dirt, eliminating cracks.
3. Wall putty with starting and finishing composition.
4. Painting the prepared surface.

Let's start by removing the old layer. It must be completely removed, be it old tiles, wallpaper, plaster or paint. Everything is cleaned off with a spatula. Wallpaper can be moistened with water.

Cracks, depressions and other defects are also eliminated. The cracks are widened and filled with starting putty.

There may be electrical wiring running through the wall. Therefore, when removing the finishing, you need to be careful not to short-circuit the system and get injured.

Preparing walls before puttying includes priming. To do this, you need to clean the walls from dust and dirt, cover the surface of the wall with a primer without leaving any gaps. After treating the surface, you need to wait until it dries.

Why prime the walls? A layer of primer creates a film on the surface, which not only improves adhesion to the surface, but also reduces the consumption of the composition. And if the composition has antiseptic additives, it can prevent the formation of mold and mildew.

Puttying work

You need to understand the difference between plaster and putty. The plaster is coarse-grained and is used to level walls for painting if the differences are quite large. But putty allows you to create an optimal surface for painting. It will be smooth due to the small particles used in the composition. The technology of wall puttying involves applying several layers with a break for each to dry.

When the layer has dried, it needs to be sanded. This allows you to smooth the surface, remove protrusions and tool marks. The work is performed with a grinder or a special grater. The whole process lasts approximately several days.

The main task is to make a perfectly flat surface, without flaws, cracks and protrusions. The quality of the clutch also plays a big role. Usually 3 layers are created: a starting layer and two finishing layers. However, professionals can create more - up to 6 layers.

If the layer is thick, it may crack. To avoid this, you need to use a reinforcing mesh. It is embedded in the putty and does not allow it to crack.

Selecting tools for work

Without the right tools, you won’t be able to finish your walls with plaster yourself. The good news is that they are simple and accessible, low in cost, and even a beginner can work with them. They are as follows:

• roller and brushes for work;
• construction mixer for mixing mortar;
• a set of spatulas (wide, medium and narrow), a fine-grained grater;
• rule for controlling the evenness of the base;
• mixing container.

The wide one is from 30 to 60 cm wide, it is used to carry out basic work, the medium one is 20–25 cm wide, it is used to process corners, and the narrow one (from 5 to 10 cm) is used to collect the mixture. To fill the corners and make them smooth, use an angle spatula.

Applying starting putty

We will work with starting gypsum putty with additives. The technology for puttingtying walls for painting is as follows:

1. Using a wide spatula, you need to transfer the mixture to the wall. The thickness of the layer depends on the quality of the surface. All irregularities are hidden, most often 3 to 12 mm is enough. The wider the spatula, the more mixture will be applied and the faster the work will be completed. But, it is difficult for beginners to work with a tool that is too wide.
2. To save effort and time, further work does not have to be done after the first layer has completely dried. Enough for it to dry and set. In this case, there is no need to apply a primer either.
3. The surface will dry for about 8 hours, it all depends on the type. After this, you can start sanding using a sanding machine. Alternatively, use coarse sandpaper.

Finishing layer

Finishing the wall requires a lot of effort, as any defects will be obvious. In addition, the thickness of the putty layer is small, only 2 mm. Therefore, the application technology has some differences:

1. The mortar applied to the wall must be stretched so that a thin layer remains, filling cracks and depressions.
2. The number of layers depends on the quality of the base layer. Usually 1-2 is enough. If a newbie works, the number increases. You can check the evenness using a flashlight or lamp.
3. After drying, you need to sand it. Only this time you will need a fine-grained grater. You need to thoroughly wipe down all the walls, leaving no gaps. All that remains is to clean off the dust from the surface of the wall and cover it with a primer.

Now everything is ready to paint the surface. We learned how to properly putty walls for painting. And although at first glance the work may seem simple, it is followed by more than one day of technological process. It begins with the selection of a suitable mixture, the preparatory stage, which includes cleaning and priming the walls, as well as directly with putty. You need to apply a starting and finishing coat. And only when you have achieved a smooth surface, you can proceed to the simplest type of decorative finishing - painting.

TO Everyone who makes repairs is faced with the need to putty the walls before. This task is not difficult to complete, and it is quite possible to carry it out without the help of a specialist, but before that it is worth understanding the nuances. We will talk about the different compositions and purposes of solutions, methods of their preparation, necessary tools and materials, as well as the application technology itself. Do-it-yourself finishing putty for painting will seem like an elementary task after reading the article.

An even and smooth base will make the paint application process simple and the result excellent. If you apply paint to an unprepared wall, then all the bumps, irregularities, and cracks will be clearly visible after the repair is completed.

In addition to its aesthetic function, putty is also responsible for strength. It strengthens the walls and the coating becomes more durable.

Each composition has its own purpose

Before applying the finishing putty for painting with your own hands, you should select the desired composition of the solution.

• Oil-glue. This is the cheapest option, but not entirely safe. Drying oil can negatively affect modern wall finishes and appear as stains during subsequent repairs. However, it is advisable to use it in storage rooms, basements, and bathrooms.
• Gypsum cement. Sold in the form of dry mixtures that need to be mixed with water. Not so cheap, but suitable for residential buildings and rooms with high humidity.
• Water-dispersed. It is mixed with a polymer emulsion at the production stage, so it is sold in buckets. It does not require additional preparation and is perfect for beginners.
• Acrylic. It has many advantages, but is completely unsuitable for cheap paint that does not stick to it.

Finishing putty for painting, carried out in compliance with technology, will make the wall perfectly smooth.

How to prepare for puttying?

First of all, tidy up the walls. There should be no protrusions, wallpaper, paint or stains left on them. All deep cracks and furrows need to be sealed. If there are nails or fittings sticking out in the wall, they must also be removed.

An integral preparatory stage is priming. The primer is selected depending on the type of base. The prepared mixtures are applied to the wall using a paint roller. After the primer has completely dried, puttying can be done.

Finishing high-quality putty for painting cannot be done without the right tools.

• Sandpaper P80 or P120.

• Special container for mixing.

Before starting work, all tools are wiped free of dust.

Calculate in advance how much material you will need. Consumption per 1m2 is written on the packaging, but this is an average value. If the walls are uneven and you have to lay the putty in a thick layer, then the consumption may increase.

Stages of work

The application of finishing putty for painting occurs in 2 stages: applying a starting layer with a coarse-grained base and a finishing layer. The first will correct the imperfections of the wall, making its surface perfectly smooth. The second one forms a dense, uniform layer on which the paint adheres well.

• Mix the mixture

To mix the putty, you need a container that is filled with water a third or a quarter. Pour the mixture in a stream until the top appears above the liquid. The mixture should sag in 5-20 seconds, after which it is kneaded for no longer than 2 minutes, paused for one minute and kneaded again.

• Apply putty

The finished mixture is applied with a wide spatula at an angle of 20 - 30 degrees in overlapping strips. You can also use nylon mesh. Then you will achieve the correct layer thickness - up to 4mm. Next, you should wait until the putty dries and check for evenness. The lumps are removed with a jointer, and the holes are covered; The wall is sanded with sandpaper.

The second layer is applied with large and small spatulas, its optimal thickness is 1.5 - 2 mm.

• Apply putty to the corners

Painting is a universal finishing method with a wide range of decorative techniques: from plain walls painted in any of many shades, to designer painting using stencils and templates. However, any design idea can come to nothing if there are cracks, differences and other defects on the surface of the walls to be painted. The problem is that all the unevenness of the base is very noticeable when light from a window or other source falls on them at an angle. Puttying before painting corrects the slightest irregularities in the walls and gives them perfect smoothness. Thus, puttying is a very important process, but painstaking and takes a lot of effort and time. However, anyone can cope with it by showing persistence in following all the rules and technologies.

In this article we will tell you how to get a perfectly flat and smooth surface for painting, and we will give tips that will help even an inexperienced craftsman do everything efficiently and beautifully.

It should be noted that not all surfaces are suitable for puttying. These can be plastered and plasterboard bases, walls and ceilings in monolithic and panel houses, provided that they are installed level and do not require leveling. But it will not work to putty on bare brickwork, since the putty is applied in a layer of up to 15 mm, and leveling such a wall may require a much larger layer.

1. Types of putties

There is a huge selection of putties on the building materials market, which differ in different parameters.

By degree of readiness differentiate dry and ready mixtures. Dry mixesattractive low price, andreadythe compositions have an ideal homogeneous consistency, do not take time to mix, and do not require additional tools and containers.

By method of application isolate compoundsfor manual And machine application. Putty for mechanized application has a smaller fraction and a longer shelf life of the finished solution. It is used on large sites to reduce labor costs and speed up the process.

In addition, putties differ in manufacturer, type of container and packaging.

All these parameters rather determine the ease of use of the putty in each specific case, and the main thing when choosing a material remains the scope of its application. This could be a kitchen, a bathroom, or even a wall in an open gazebo, that is, a surface in conditions of high humidity and temperature changes. Or you need to paint the walls in a children's room, where the harmlessness and hypoallergenicity of finishing materials is especially important.

The scope of application of the mixture determinesbinder in its composition (cement, gypsum or polymer). Let's take a closer look at each of them.

Thanks to the main componentcementThe putties are moisture-resistant, which allows them to be used in rooms with high levels of humidity, for example, in bathrooms and kitchens. They have no analogues in terms of strength. As a rule, cement putties are frost-resistant, so they are excellent for finishing facades, open balconies and window slopes. The relatively low price is another plus. Disadvantages of this material: difficulty of application, long drying period and ability to shrink.

Plasterputties have a number of advantages: low cost, huge range, vapor permeability, hypoallergenic, good adhesion to paints, wallpaper and other finishing materials, ease of application, no shrinkage. This putty sets quickly, so it requires some skill in application. Despite all its advantages, the scope of application of gypsum putty is limited to heated rooms with normal humidity levels. So, it is ideal for bedrooms, children's rooms and living rooms.

IN polymer With kneading astringent thingsThe materials used are acrylic resins or latex. Only this type of putty is sold both dry and ready-made. The range includes models that can be used in both dry and wet areas. For example, dry polymer puttiesProspectors Finish Plus And Founded Ekonsilk PP38W for rooms with any level of humidity, and ready-made polymer puttyDanogips SuperFinish only for dry rooms. Polymer putties fit well on plasterboard bases and can be applied in an ultra-thin layer, reducing material consumption. The mixtures are supplied in sealed plastic buckets, which can be stored for a long time even in a humid environment, unlike plaster and cement ones, the paper packaging of which easily gets wet. The price of polymer putties is much higher than gypsum and cement putties. But the wide range of choice, ease of use and guaranteed high quality of the putty surface will justify the investment.

So, we figured out the scope of application. We found out that only cement putties are used in exterior work. For wet rooms you need to choose from cement and polymer compositions. And for dry rooms, any putty is suitable, but gypsum or polymer are considered the best option.

Remains deal with the wallsin these very premises, namely -how smooth are they?. There are divisions of putties by purpose: for starting(basic), finishing And universal.

1.1. Starting putty

Starting (or base) putty is used to smooth out significant surface defects. Its features are large particle size (coarse grinding), crack resistance, and the ability to apply it in a thick layer (up to 12-15 mm). This is an inexpensive dry composition, usually cement-based (for example,Prospectors Basic gray, 20 kg with layer thickness up to 8 mm) with a long period of complete drying (usually 24 hours). Using rules and beacons, you can use it to correct gross defects in plaster. The base layer is not ideal and is not suitable for further painting, because, firstly, it is gray in color (since the base of the mixture is cement), and secondly, it is too rough. Therefore, after complete drying, a layer of finishing putty is applied to the starting layer.

1.2. Finishing putty

The finishing putty has a fine-grained structure, which allows it to be applied in an ultra-thin layer. It is not allowed to apply this putty in thick layers - the maximum layer thickness is 3-4 mm. Working with this material is easy, thanks to its good ductility and softness.

The finishing putty for painting can be ready-made polymer (such asProspectors Superfinish Paste, 15 kg with application thickness from 0 to 2 mm), dry cement (Weber.Vetonit VH, 20 kg with a layer thickness of 1 to 3 mm) or dry polymer (Knauf Polymer Finish, 20 kg with layer thickness from 0.2 to 4 mm).

1.3. Universal putty

Using two types of putty can be a difficult task for a novice craftsman: you need to choose the right materials to combine, correctly calculate the required amount, spend twice the time drying each layer, and also financial costs. To simplify the task, universal putties are designed, which have a medium grind and have absorbed the best properties of starting and finishing mixtures. With their help, it is easy to make the surface for painting smooth (though you have to sand more), and a layer can be applied, if necessary, up to 1 cm.

Universal putty is suitable for both types of work, but more often itused for closing joints of sheet materials (gypsum plasterboard, gypsum fiber board, PGP, chipboard and others) or sealing cracks and holes.

Gypsum compositions are universal (for example,Knauf Fugen, 25 kg with a layer thickness from 1 to 5 mm) and polymer (Prospectors PolyArt super white, 20 kg with layer thickness from 0.2 to 5 mm).

2. What you need to know about preparation

So, we figured out the types of putties and chose the appropriate material. All that remains is to prepare the tools necessary for the work and prime the walls.

2.1. Working tools and materials

A properly selected tool plays an important role in obtaining a quality result. To prime and putty the walls you will need the following: tools :

• Wide roller for applying primer to walls;
• Brush for priming corners and joints;
• Construction mixer, electric drill or hammer drill with a mixer attachment for mixing the solution;
• A bucket for stirring and a brush for cleaning it after each batch;
• Rigid large spatula (30-35 cm wide) for quick and even filling of large surfaces;
• A flexible small spatula (about 10 cm wide) for finishing hard-to-reach places and for applying the mixture to a large spatula;
• Corner spatulas for surface treatment in the outer and outer corners of the room;
• The rule is 1 to 3 meters long depending on the area;
• Bubble level, plumb line and construction pencil for marking;
• A sanding machine, fine-grained sandpaper or a construction float for final sanding of walls for painting.

Necessary materials :

• Selected putty;
• Primer;
• Perforated corner profiles for strengthening internal and external corners and arches;
• Beacon profiles with a height from the base to the ridge of 6 mm or 10 mm for applying the starting layer, as well as dowels, screws and fastenings for their installation;
• Serpyanka fiberglass mesh for puttying joints of plasterboard sheets and cracks in plaster.

2.2. Preparing walls before puttying

Before puttying, first of all, we clean the plastered walls with a hard spatula from deposits of plaster and particles of debris, after which we brush off the dust from the walls with a brush or broom. This will provide better soil adhesion to the surface.

To strengthen the corners, we install metal or plastic perforated corner profiles (corners) on them. We attach them to the same putty, screws or a construction stapler.

In plasterboard structures, cover with fiberglass mesh and cover with special putty (Knauf Fugen ) joints between sheets, screw heads, cracks and dents.

After the first layer has dried, a second one is made, which aligns the seams in the same plane with the drywall, after which the walls are cleaned.

After the primer has completely dried, it is recommended to apply it with a second layer. In this case, the walls will draw less moisture from the putty. This way the putty will harden more slowly, which will leave more time for its distribution and leveling on the surface.

3. Technology of puttying walls for painting

The walls have been prepared. We begin to putty. The putty is applied in several stages: basic leveling, finishing and final sanding. This process takes a long time, since you will have to apply at least three layers and let each of them dry completely.

3.1. Starting layer of putty

The initial stage of putty levels out surface defects up to 12-15 mm deep, so the starting composition is applied in a thick layer.

For deep point surface defects (for example, joints of drywall sheets, places where self-tapping screws are screwed into drywall, cracks and dents), putty is applied, over whichlay fiberglass mesh or paper reinforcing tape. Press it down a little, but so that folds and bubbles do not form. Leave to dry.

If there are deep unevenness throughout the entire area, then you will have to level it using beacons. Beacons can be installed in several ways. The fastest and easiest way is to attach them to special clips (galvanizedKnauf Kremmer Clips or plasticMounts for beacons AriaStroy ). For this, in addition to beacons and clips, you need a hammer drill, dowels and screws, as well as marking tools. First of all, drill several holes on the applied markings with an equal space between them. Place the dowels in them and tighten the screws so that their heads are in the same plane as the marking threads. Place the clips on the screws and secure the beacon itself in them.

We prepare the solution only after installing the beacons. Use a construction mixer or a drill with a special attachment for this. Remember that gypsum putty has a short pot life of the solution, so you should not dilute a large volume. In addition, if the puttying process is new to you, then regardless of the type of mixture, it should be diluted in small portions to get used to it. It is necessary to have time to use up the entire solution before it hardens in the bucket.

Important! After each batch, you need to thoroughly wash the bucket and clean it with a brush from hardened particles of the solution so that they do not get into the next batch of fresh solution and damage the coating.

When using beacons, simply add the first layer of putty between the beacons and smooth it out from the bottom up. As a result, air bubbles form on the surface. Break them apart with a spatula, sprinkle some putty on them and run the rule over the beacons again.

Let's reveal the secret of an ideal result: 30-40 minutes after leveling one span, apply the rule from top to bottom. This action will straighten the beacons that sag a little during puttying.

In putty work without beacons, apply putty with a large spatula. Scoop the mixture from the bucket with a spatula and apply the mixture from it onto the large one. The optimal tilt of the tool is 45 degrees. It will not be possible to remove the putty the first time.After applying a thick layer, wait about a minute and remove excess with a clean spatula. In this case, there will be fewer grooves and the mixture will not slip (as usually happens on gypsum board).

After leveling, leave the surface to dry for several hours.

3.2. Finishing putty

Wash the tool thoroughly after applying the base putty. We will continue to work with them. The technique of finishing putty does not differ from the starting one, it is simply laid in a layer of no more than 3 mm.Hold the putty knife at a 90-degree angle to the wall and apply firm pressure while applying the mortar. The result is an ultra-thin layer that will fill the smallest grooves.

We continue to putty until we get the most even surface for painting, after which we leave it to dry.

3.3. Grout

After waiting for the putty to dry completely, we begin to sand it. There is a manual and mechanized method.

Mechanized methodgrinding significantly speeds up the process, but the quality suffers (a line from the sandpaper remains). Before painting, you will still have to go through the surface manually. In addition, the cost of the equipment is quite high. Therefore, this method is suitable for professional craftsmen who regularly carry out repair work.

Advantages of the manual method - this is the ease of work and the availability of equipment. In this case, sanding is done with sandpaper of P180 grit (for example,Yoko P180 sandpaper on a fabric basis, 230×280 mm ) or an abrasive mesh. In addition to them, you will need a sanding block (for example,Grinder with handle 230x105mm, STAYER ).

Important! To protect yourself from dust, be sure to wear a respirator, goggles, as well as protective gloves and a hat.

Carry out the work carefully in a circular motion. You need to rub thoroughly, there should be no protrusions or roughness left..

Advice: You can check the evenness of the walls using directional light from a flashlight or lamp.

At the end of the work, all that remains is to remove dust from the surfaces to be painted using a vacuum cleaner and apply primer. And the walls are ready to be painted.

How to putty walls for painting

/articles/kak-shpaklevat-steny-pod-pokrasku/

Many novice repairmen or simply people who have decided to carry out high-quality home renovations with their own hands are wondering - how to putty walls for painting? And the question is quite fair.

Immediately before painting the walls of the room, it is necessary to carry out putty work. Today, there are various types of putties, with the help of which the most seemingly uneven wall can be made smooth and its surface given an ideal appearance, while the paint on such a plastered wall will lie very, very well.

To carry out puttying work you will need a set of special tools. And if you are also a beginner, then in addition to them, patience will also be useful to you! It is worth being aware that the first experience of puttying walls will be very, very slow. But the main thing is the result, isn’t it?

What will you need?

To putty the walls with your own hands before painting, you need to purchase an ordinary construction folding ladder, or rather a ladder, since we don’t need big ones. Of course, in a pinch, a regular old chair will do.
You will also need:

• an old bucket or basin of sufficient volume;
• what we will use to mix the putty (a drill with a special attachment, for example);
• spatulas of various sizes;
• brush and roller;
• a tool that allows you to grind a surface.

It is worth remembering that puttying work is quite dirty, so if there is parquet, laminate or other material on the floor in the room that you do not plan to change after working on the walls, then you need to cover it with something. Film or paper will do. This way we will preserve the floor and protect it from work debris.

Preparing the walls for putty

Before you start puttingtying the walls with your own hands, you will have and will need to work with the walls, clean them from cement deposits and other irregularities. Of course, old wallpaper or paint will also need to be removed.
If there are stains of grease or rust on the walls, then special products will be required to treat these stains. All cracks, holes and cracks should be sealed with primer.
The primer itself is the final stage of preparing your wall for putty. Primer compositions can be purchased at any hardware store. It is recommended to prime the walls using a roller. In places that are inaccessible to a roller, a brush is used. If the normal humidity level in a room is exceeded for one reason or another, it is recommended to use a waterproofing type of primer. You can start leveling the walls.

Types of putties and their features

There is a wide range of putties with very different sets of characteristics. Let's look at each in detail.
1. Gypsum putty. The advantages are environmental friendliness, no shrinkage, high drying speed, excellent heat and sound insulation. It is plastic and has good fire resistance. Disadvantages: not suitable for rooms with high humidity, relatively expensive, difficulties in preparing the solution (since it dries quickly, you have to mix the solution often, and in small portions).

2. Cement. Ideal for puttying concrete, stone or brick walls. Quite cheap. When choosing this type of putty, you should not think about humidity levels. Good resistance to temperature changes. Disadvantages: low elasticity and possible shrinkage.
3. Polymer putty. The advantages include ideal strength, resistance to various temperature conditions, and lack of shrinkage. It is quite elastic and has a high level of adhesion to any type of surface. The only negative is the high cost.
If you imagine yourself as a specialist for a moment, then you need to choose polymer putty. It is very easy to work with, and the adhesive properties are quite attractive.

Calculation of the amount of consumables

The packaging of any type of putty indicates the approximate consumption per square meter of working surface.

To roughly calculate how much composition is required, you need to measure the length and height of the walls that are to be puttied, multiply and add them. Subtract the area of ​​windows and doors from the resulting value.

It is recommended to take putty “with a reserve”, since not everything can turn out perfectly the first time, and besides, it is not known what layer of putty will have to be applied to the walls (irregularities, bevels, etc.).

Main point

The most important and basic stage is directly puttingtying the walls. It is worth considering that the putty is applied in several layers. The base layer is intended to level and correct the most noticeable defects. Secondary layers have the function of finishing.
To apply putty to the main working area, use a wide spatula.
Hard-to-reach places are treated with the help of a small one. After the wall is puttied and dry, we use the tool we have chosen for sanding the walls (for example, ordinary sandpaper).

It should be remembered

In order for the putty of walls to be painted with your own hands to go really well and look perfect, you need to remember a number of simple rules:

• After applying the base (the base layer we talked about), you should let it dry. Apply the next layer strictly after drying;
• During the drying process, you should prevent sunlight and especially hot air from hitting the walls. Such measures or situations can cause destruction of the putty structure;
• It is recommended that the mixture, regardless of the type of putty, be prepared in equal small portions to avoid drying out before application.

From recommendations for completely “green” beginners: before working on a large area, allocate a smaller piece for yourself and practice properly. This will allow you to learn the basics of the business you have started and acquire initial skills.
At the very end of the work, as we have already found out, we wait for all the applied layers to dry completely, then we carefully sand it with sandpaper or any other tool suitable for this, and then apply an additional layer of primer. Before the priming process, it is recommended to clean the working surface over the entire area from dust residues and various suspensions that could remain on the walls after the grinding process. For this purpose, a vacuum cleaner with a separate bag, which we will throw away later, or dry rags are suitable. Strictly dry! It is strictly forbidden to use damp or wet ones.
Now that you are literally a master of your craft, let’s allow ourselves a little rest.

The eternal dispute

Putty or putty? Interest Ask! Manufacturers write this and that on the labels of their products. So which option is the right one and why?
In fact, the essence of the word is the same. Although it is generally accepted that the word “putty” is more correct, both names are permissible and even generally accepted.
Finally, when you have finished plastering the walls for painting and are enjoying the result of the work, looking at the perfectly even and smooth surfaces of the walls, you can safely consider yourself a master of your craft and begin painting work! Good luck in all your endeavors and perfectly putty walls!
