Exist various options ceiling finishes. Today, the stores offer a huge range of materials for this. One of the most popular and relatively inexpensive is water-based acrylic paint. For the ceiling, this is quite an acceptable option. Many believe that this finish is the least laborious of all. existing options. In the article, we will see if this is so.
Material advantages: consumer opinion
Why do many owners choose water-based paint? As consumers themselves say, this material has many undeniable advantages. First of all, home craftsmen note that this coating dries very quickly. In some cases, just a couple of hours is enough for this. Many people choose coloring compositions of this type because of their safety not only for humans, but also for pets. The composition does not contain caustic or bad smell. So after application, there is no need to urgently leave the room. The composition can be given a different color. For this, special water-based colors are used. Subject to the recommendations, the staining process does not cause many problems. One of the undoubted advantages of the compositions, consumers consider that the tools can be easily cleaned after application.
Possible difficulties
Ceiling whitewashing water-based paint should be of very high quality. Otherwise, glare and streaks will be visible on the surface. I must say that painting the ceiling with water-based paint the first time may not work. It is especially difficult to achieve a perfect surface for those who have never done this until now. At the same time, re-painting the ceiling with water-based paint will not hide, but, on the contrary, will increase the visibility of defects. There are several nuances that are usually not taken into account.
Why do spots appear on the surface?
The occurrence of defects can be due to several reasons. First of all, before whitewashing the ceiling with water-based paint, you should take into account the features of the lighting in the room. Stains can also appear when using a low-quality composition. The choice of tool with which the ceiling will be painted with water-based paint should be approached with all care. An incorrectly selected or poor-quality roller can cause uneven distribution of the composition. How to purchase suitable tool? Experts do not recommend choosing a velor or foam roller. As the owners of the premises themselves say, in which the ceilings were whitewashed with water-based paint, the best is a tool with a long pile or threads. It should also be remembered that after drying, the composition forms a smooth and fairly durable film. It can give glare in daylight. If the technology of painting the ceiling with water-based paint is not followed, the work is done in a hurry, and optical effects are not taken into account, then the surface will be simply terrible.
Lighting
Before whitewashing the ceiling with water-based paint, it is necessary to evaluate the distribution of light in the room. As a rule, it is necessary to take into account the type of flooring. If it is shiny and smooth (for example, parquet, ceramic tile or laminate), then the lighting on the ceiling will be much brighter than with a pile coating. Given the optical effect that is obtained when light is reflected from the floor, the surface is covered with the first layer in the direction from the window to the opposite wall. The next one, on the contrary, is parallel to the source of penetration of natural light into the room. With a chaotic distribution of strokes, a rather unpredictable "reflection" effect can result.
Coating composition
Both layers require the same brand of paint. The ideal is the option in which the mixtures will be from the same batch. If the composition has frozen to such a state that ice has formed in it, then you should not use it. In any case, as the masters note, in such a noticeable area as the ceiling. Separation of the pigment components could occur in the mixture. Before that, it must be thoroughly mixed. There should not be a single lump in the mixture.
Tool
The roller is the most optimal device for applying water-based ceiling paint. Reviews of the owners of residential premises indicate that applying the mixture with a brush is a very time-consuming task. In addition, in the latter case, the formation of stains and glare is more likely. Suitable for work roller bright yellow.
Surface preparation
This stage, according to experienced craftsmen, is decisive in the process of painting the ceiling. The surface must be dry and perfectly clean. To soak the old coating, you can use bast brushes or a water spray in a vacuum cleaner. Next, the whitewash must be cleaned with a spatula until concrete base. After that, the surface is washed again. The ceiling must be allowed to dry. If the surface has been pasted over with wallpaper, all residues should be removed adhesive composition. As the experts point out, old layer coatings are usually removed in whole layers. The surface must be thoroughly cleaned, otherwise the new coating will lie unevenly, with defects, and will not set well.
Painting the ceiling with water-based paint: the nuances
In the process of work, as experienced craftsmen assure, there is not a single moment that would not affect the result. At the very beginning, before stirring the paint, you need to read the information on the package. Some manufacturers do not recommend further diluting the composition with water. Such paint should be thoroughly mixed directly in the factory container. Otherwise, there is a risk of leaving the pigment components in the jar. Experienced homeowners self-repair, adapted to mix the composition with a drill and a special nozzle - a mixer. If the mixture needs to be further diluted, this should be done by adding small portions of water. In this case, you need to continuously mix the composition. When adding water, the main thing is not to pour too much of it, since it will not work to “thicken” the paint back.
Convenience fixture
After the paint is mixed, it must be poured into a container with a wide bottom. For these purposes, a plastic cuvette is perfect. Usually it is used when developing photographs. If there is no such device in the house, then it is quite possible to replace it. wooden box for fruits. First you will need to cover the bottom with polyethylene.
How to paint the ceiling with water-based paint?
The paint roller should be dipped into a container (special paint bath) with the composition and rolled over the surface on it until it is completely and evenly distributed. For convenience, a long handle is attached to the tool. The application of the layer can be called the most crucial moment. As professionals say, movements should be straightforward, fast and confident. At the same time, one should not forget about the direction. The first layer is applied from the window to the wall. As soon as there is not enough paint, the roller is again dipped into the container.
Subtleties
Painting the ceiling with water-based paint is not an easy job. It is necessary to take into account one nuance when applying a layer. The area covered with the composition should not be looked directly from the bottom up, but at an angle (approximately 30-40 degrees). In this case, all defects and errors of the layer will be visible. It is better, of course, if there is an assistant who will tell you where there are unpainted places. As long as the paint layer has not dried up, errors can be eliminated. But after drying, this can only worsen the situation. As experienced craftsmen say, it is highly not recommended to be distracted from the process. Painting the ceiling with water-based paint is done without lunch breaks and smoke breaks. Applying a second layer can both correct errors and aggravate them. It should be remembered that re-staining is carried out after the surface has dried. If it was not possible to correct the defects with the second layer, it is not advisable to apply the composition for the third time. In this case, only removing the entire coating and repeating the process from the very beginning will help.
We reduce the time of work
Any painting work using a brush or roller is considered quite laborious. The process often takes a long time. Painting the ceiling with water-based paint with an airbrush will significantly speed up the process. This version of the application of the composition has a number of features. Let's consider them further.
Preparation
The paint, as well as when applying it with a roller, is thoroughly mixed beforehand. In this case, it is necessary to absolutely exclude the presence of lumps in the mixture. If they remain, they can clog the spray gun, and the mixture will lie unevenly. If it is supposed to give the composition any shade, color is added with stirring. You need to pour it in small portions. It is unacceptable to leave stains of pigment in the paint. The composition must be homogeneous. Experienced craftsmen it is advised to prepare the paint with a margin, because if it runs out and the surface is not completely covered, then it may not be possible to pick up a perfectly accurate tone.
Important Details
It should be remembered that when applying the mixture with an airbrush, a sufficiently large volume of the sprayed composition hangs in the air. It will settle not only on the surface being treated, but also on all the others that are in the room, not excluding furniture. In addition, it is necessary to protect the face and especially the eyes from sprayed paint. Therefore, work must be carried out in a respirator and glasses. Remove all furniture from the room. If this is not possible, then the items must be carefully closed with polyethylene, fixing it with tape.
Progress
Using an airbrush allows you to get a perfect surface without defects. When applying it is very important that the layer is thin and even. Immediately before application, you should take the spray gun nozzle a little to the side and press it briefly several times. As soon as the spray is uniform, you can start applying to the surface. The spray gun should be kept at a distance of about 30-50 cm from the ceiling. The jet of paint is directed directly perpendicular to the surface.
How to make the process easier
Mentally, you should divide the surface into squares. The width of each should be approximately equal to the length of the arm. Staining areas should be done in turn. Layers are applied first transversely and then longitudinally. When using the spray gun, in no case should you stop or linger in one place. In this case, the layer will be too thick or the paint may leak. Work should be carried out at the same pace.
How to apply the composition
The recommended number of layers is three. Each new one is applied only after the previous one has dried. Do not paint over a fresh layer of coloring compound or primer. Otherwise, the mixture will lie poorly and may exfoliate quickly enough. This will lead to a complete overhaul. To create the first and third layers, the morning and evening hours are considered the best time, when there is good daylight in the room and the direct rays of the sun do not blind. Although this recommendation is not necessarily followed exactly. The most important thing here is that all the errors in applying the composition are visible, and the angle at which the light falls is as close as possible to a constant for the repaired room.
Painting walls with water-based paint remains one of the easiest and most available species finishes. The variety of colors and excellent results allow it to maintain its popularity. The application technology is very simple, you can handle it yourself without the involvement of specialists. At the same time, the finished surface fits perfectly into any design, creating a modern interior.
Comparing water-based paint with other types of finishes, the following advantages can be distinguished:
- it will take about 2 hours to dry;
- contains only safe, non-toxic components;
- does not have an unpleasant odor;
- you can get any color or shade.
The main components of the paint include latex, filler, thickener and antiseptic. It can be applied with a roller, brush or spray gun. For do-it-yourself work, the viscosity of the composition should be no more than 45 s, and when using an airbrush - 25 s. Material consumption is on average up to 200 ml per m2. When choosing it in the store, you also need to pay attention to the expiration date, storage conditions. If the paint is frozen, then the structure is broken, it cannot be used.
Types of water-based paint
Despite the name “water-based paint” traditionally used by everyone, there are several types of this material. The main component by which the paint is divided into separate types is a polymer - acrylic, silicone, silicate, mineral. It affects the convenience of working with the composition, its performance characteristics.
Acrylic paint is made from acrylic resin. The latex included in it improves the hiding power of the composition, smoothes out the slightest cracks. Acrylic paint is recommended for painting surfaces exposed to water. It fits perfectly on plaster, wood, brick, glass, suitable for painting walls and ceilings. double layer acrylic paint major damage can be repaired.
Using silicone resins, a silicone compound is obtained. Its purchase will be expensive, but the result will make up for the costs a hundredfold. Even one layer of it is able to eliminate cracks up to 2 mm wide. The coating has vapor permeability, does not become infected with a fungus. It can be washed without fear of spoiling.
From a mixture of water, pigments and liquid glass receive silicate paint.
It creates a vapor and breathable layer, evenly applied to the base. It is distinguished by increased resistance to weathering, durability. But in damp rooms it is better not to use it.
Mineral paint is recommended for work on concrete or cement surfaces. It contains cement or slaked lime which significantly improve its water resistance. The material is suitable for painting ceilings and walls. The disadvantages of the composition include its fragility.
Color selection
An interesting fact: when talking about a water emulsion, they always emphasize its ability to transform a room, fit into any design. The base color of the composition is white. By adding a pigment of one or more shades, the composition is given the desired shade. You can do it yourself or use a computer selection.
For tinting, you need to use a color designed for water-based emulsion. It is produced from acrylic dispersion in three formats: powder, emulsion, paste. Liquid color is considered the most convenient to use. It mixes well with the base composition, creates a homogeneous mass. The finished paint fits well on any surface - plaster, brick, wood. Advantages of ready-made colors:
- allow you to get shades that are not on sale;
- have high resistance to fading;
- easy to use by hand.
The variety of possible shades is amazing. But it should be noted that it is almost impossible to repeat the desired color combination on your own. Therefore, when doing repairs with your own hands, it is better to immediately dilute the right amount of paint. When wet and dry, the shade is slightly different. The coating will look different in different lighting, applied to a different base. Therefore, before painting the entire wall, it is better to try on an inconspicuous area. Of course, a slight variation in shade will not spoil the design of the room, but in large areas it can be noticeable.
How to mix color with paint?
When painting with your own hands, you need to properly dilute the color scheme. This should be done shortly before use. The maximum amount of color should not exceed 30 ml per 1 liter, that is, no more than 3%. A large amount of pigment can affect the quality of the paint. In order not to make a mistake with the shade, you can use this method:
- prepare 3-4 clean small containers of a known volume;
- pour paint into each and add a different number of drops of color;
- apply a strip of each type to the surface;
- choose the result you like.
Then you need to recalculate the amount of paint and drops for the desired volume. After that, you can proceed to breeding. You will need a clean container, into which no more than 20% of paint is poured. The calculated volume of color is added to it and mixed thoroughly. The finished mixture is gradually poured into the main container with paint.
Surface preparation
The base must be free of layers before painting. old finish- paints, wallpaper, whitewashing. The easiest way to remove the whitewash, it is simply washed off with water. The wallpaper can be pre-wetted slightly, and then gently pry with a spatula and remove. Harder to remove old paint. It is not soaked with water, it will have to be scraped off or a special wash should be used. The surface should then be inspected for damage, mold or rust. If necessary, stains should be treated with copper sulphate.
The next step is alignment. Even small bumps or cracks under a layer of paint will take on an ugly look, spoiling the most expensive design. Therefore, they need to get rid of. Putty works great with this. Depending on the condition of the surface, only finishing or starting and finishing putties are used.
First, the surface is primed and left to dry. The starting putty contains a coarse-grained filler, so it effectively eliminates fairly large cracks and pits. The dried layer of putty is treated with a coarse-grained sandpaper. As a result, traces of a spatula and irregularities are eliminated. The coating is again covered with soil.
The finish putty is very fine in structure. It is applied in a thin layer, allowed to dry and rubbed with a fine sandpaper. To check the quality of work, use the light from the lamp. It is directed at an angle to the wall, revealing the slightest deviations. The result of the performed manipulations is an ideal surface on which the paint will lie in an even layer.
To protect parts of the walls or ceiling that will not be painted, stick a strip of masking tape on them. The same strip can be glued along the floor. At the end of the work, it is easily removed, and the surface under it remains clean. If you need to close a large area, then you can use a strip of polyethylene, securing it with tape.
Foundation Stage
For work you will need:
- regular brush for painting corners and joints;
- narrow brush for correcting hard-to-reach places;
- roller with a long pile;
- special bath with a ribbed surface area.
In order for the result to please with its beauty and accuracy, it is necessary to take into account several nuances. Painting should start from the corner located on the opposite side from the entrance to the room. First, take a wide brush, moisten it in paint, wring it out slightly. A strip of 3-5 cm is made around the perimeter of the room. This will help make the joints and corners neat.
For further work, use a roller. Staining is carried out in three stages:
- apply the first strip parallel to the rays of light falling from the window, continue staining in the same direction;
- then make movements in a perpendicular direction;
- the third strip is always directed to the window, and so the staining is completed.
Each stage is performed after the previous one has dried. On average, it takes up to 12 hours. In order for the paint to be evenly distributed over the roller, they are carried out several times along the corrugated part of the bath. Roller movements on the surface can be straight or zigzag. The next strip is applied with a slight overlap on the previous one. Having finished painting, it is necessary to protect the room from drafts, direct rays of the sun. Drying should not be artificially accelerated.
How to make Venetian plaster with regular paint?
To the most expensive species finishes include Venetian plaster. It is distinguished by a complex execution technology, but the result is incomparable with anything. This design looks elegant, unusual and expensive. Using ordinary water-based paint, acrylic lacquer, roller, sponge, brush and sandpaper can imitate the "Venetian" at an affordable price.
First, a strip by strip is covered with a layer of water-based emulsion on a pre-leveled base - fiberboard, drywall, plastered brick or any other smooth surface. When the water emulsion dries, proceed to the creation of a "marble" pattern. It is preliminary recommended to work out strokes on a piece of cardboard.
To give the acrylic mixture the desired shade, color is added to it. Its color must match color scheme marble. For application, use a sponge, making light stamping movements. On a fresh acrylic base, you can make "cracks" with a solid rod. After the varnish has dried, the pattern is passed over with a soft brush, slightly shading the borders. Then they change the color of the varnish and apply it again to the base.
The finished coating must be given time to dry, then it is sanded with light movements. The resulting dust is not brushed off, but covered with a colorless varnish. Such actions are performed twice. This creates the inherent depth and brilliance of marble.
The demand and popularity of high-quality water-based paints are due to several undeniable advantages and ease of application.
IN last years the category of water-based paints is most often used, which has a very affordable cost.
5 advantages and 1 disadvantage of water-based paint
The demand and popularity of high-quality water-based paints are due to several undeniable advantages at once:
Pay attention to these points when choosing a paint
A significant number of different water-based paints can confuse any consumer. For painting walls and ceilings use only high quality paint and when choosing, pay close attention to the following features:
- paint composition;
- standard consumption;
- degree of viscosity;
- index specific gravity;
- expiration date and storage rules.
Optimal indicators characterizing the quality paint material, look like this:
- the composition should be represented by latex, filler, thickener and antiseptic additives;
- standard paint consumption for one paint layer is from 150 to 200 ml per square meter surfaces;
- the optimal viscosity index when applying paint with a brush is 40-45 s. and no more than 20-25 - when using a paint sprayer;
- a good indicator of specific gravity is within 1.35.
Drying time depends to a large extent on temperature regime and humidity levels, the basic indicators of which are + 20 ° C and 65%. Any shifts from this level make it possible to obtain a drying time range from two hours to a day.
In addition, it is possible to choose the material depending on the polymer included in its composition. Water-based paints can be acrylic, silicone, silicate and mineral.

4 ways to remove old paint
The most moisture-resistant paints belong to the category of water-based paints for walls and ceiling coverings based on the use of polyvinyl acetate. Removing such paints is not difficult and it is enough to use a sponge, as well as any detergent.
Removing such paints is not difficult and it is enough to use a sponge, as well as any detergent.
To remove acrylic paints after wetting the surface, use a spatula or remove wet paint with an angle grinder.
One of the most effective means to remove old paint is pasting the surface to be cleaned with newspapers using standard wallpaper paste. After complete drying, newspapers with paint are removed quite easily. It is allowed to remove old paint with a chisel or gradually anneal all painted fragments with a building hair dryer.
However, the most modern and convenient way is to use a special chemical-based remover, which, after application, contributes to the destruction of all layers of paint. They can easily wash off the paint from the walls.
How do painters paint walls?
Right before the start painting work the paint should be thoroughly mixed until smooth. If, according to the instructions, the paint used is supposed to be diluted with water, then this condition must be met, since such manipulations contribute to a more uniform distribution of the composition over the surface. In addition, if the desired shade does not match the tone of the purchased paint, then you should purchase a color scheme intended for use with water-based paints.
The surface to be painted should be as flat as possible. Regardless of whether the wall or ceiling is to be painted, all surfaces are puttied if necessary, and then treated with a high-quality primer.
To obtain the desired shade, a small amount of paint should be diluted, which should be applied to cardboard and dried. Only after these steps it will be possible to determine the correctness of the resulting color.
The surface to be painted should be as even as possible to paint the walls without streaks. Regardless of whether the wall or ceiling is to be painted, all surfaces are puttied if necessary, and then treated with a high-quality primer.
The best solution for wall painting
The room before painting should be as free as possible. The surface of the walls should be puttied and washed very thoroughly. All work is recommended to be carried out using a respirator, goggles and work gloves.
When painting already putty walls, it is advisable to apply paint in three layers, of which the first will be represented by primer. Wall painting on wallpaper can be done in only two layers. The process of phased painting occurs by applying parallel stripes in the direction from window opening. The most effective way to paint the surface of the walls with the help of special equipment. The best option -using a spray gun. This equipment is different high performance and has the ability to cover a large area for painting during operation.
If used manual way painting walls, then preference should be given to a wide brush with a size of at least ten centimeters. The bristles of such a brush are immersed in the paint by one third. All excess paint is removed by pressing the brush against the side of the container. Works are performed with short movements of vertical and horizontal direction and from top to bottom.
It is allowed to paint the walls with a roller, which allows you to perform the work most quickly and efficiently. Using a roller requires more coats of paint. In addition to the roller, a special tray is always used, which helps to evenly distribute the paint over the entire surface of the roller.
How to paint the ceiling as evenly as possible?
The most crucial moment when painting the ceiling surface is the most even application of paint. For this purpose, a high-quality wide roller is used, which must be completely covered with a layer of paint. Only after rolling the roller with paint on the construction tray you can apply paint on the ceiling surface.
A high-quality wide roller is used, which must be completely covered with a layer of paint. Only after rolling the paint roller over the construction tray can paint be applied to the ceiling surface.
The dominant principle of painting the ceiling surface is to apply water-based paint in extremely even parallel stripes. Characteristic difference consists in overlapping each subsequent strip of paint of the previous one by two or three centimeters.
It should be borne in mind that a high-quality painted ceiling can be obtained by applying at least three layers of paint, and the thinner each layer is, the more uniform and even the ceiling surface will be.
After the main area of \u200b\u200bthe ceiling surface is painted with a roller, it is necessary to paint over everything with a thin brush hard-to-reach places- joints and corners.
The most important thing when painting the ceiling with any type of water-based paint is to observe the direction of application of the material. The basic rule when applying the final coat of paint is the direction of all movements towards the main light source in the room. This painting principle helps to perfectly mask all minor defects and qualitatively level out any inhomogeneities characteristic of the coating structure, and most importantly, you can do it yourself with your own hands.
After the main area of \u200b\u200bthe ceiling surface is painted with a roller, it is necessary to paint over with a thin brush all hard-to-reach places - joints and corners. It is possible to evaluate the quality of the completed painting only after the complete drying of the applied water-based paint.

Video instruction
Currently, the construction market has many new finishing materials for walls. Nevertheless, painting walls with water-based paint is still quite popular. Using water-based paint, they give the surface of the walls both the desired color and the required texture. All this depends on the method of applying water-based paint, as well as on the use of various tools (in particular, textured rollers). If you follow the necessary rules and technological methods, the use of water-based paint will allow you to get a stunning effect.
Wall painting tools
- the topic of a separate conversation, here, too, there are subtleties. We will assume that the walls are leveled and plastered or they have already been coated for painting (wallpaper, tiles, cork, etc.).
Wall preparation for painting
Clean the entire surface to be painted, and also the space around it at a distance of 1 - 1.5 meters. In order not to accidentally stain the ceiling with paint, glue masking tape on the border with the surface to be painted, the same is done at the joints with adjacent walls. The floor is covered with cellophane, paper or just old newspapers at a distance of about 1 meter from the surface to be painted.
First you need to prime the surface. This is necessary for several reasons. Firstly, primer significantly improves adhesion, that is, the adhesion of paint to the surface; Secondly, the absorption capacity becomes the same over the entire area of the wall, in connection with which the paint itself lays down more evenly, spots do not form. The primer dries well after about 4 - 6 hours with the formation protective film. Drying time is indicated in the instructions for the primer. In addition, the drying of the primer is determined tactilely.
Cooking paint
Since the emulsion is sold concentrated, thick in its consistency, it needs to be diluted with water so that it can be applied evenly over the entire surface.
After adding water, water-based paint must be mixed with a mixer or drill with a mixing nozzle. But if you plan to create a rough surface using water-based paint, it is, of course, not diluted.
It is possible to prepare water-based paint before starting work, but when starting work, it will still need to be mixed again, since it tends to settle. So, we have reached the necessary thickness of the paint, it is now necessary to give it the desired shade. To do this, there is a wide range of colors, mixing which in certain proportions get one or another color of paint. It is better to do this when buying paint and color. Most hardware stores offer a computer-controlled automatic color matching service. Thus it is possible to obtain required amount water-based paint of the desired color for painting all the walls of the room. In this case, the color of one wall will not differ from the color of the other. If you mix by hand, then this effect will be almost impossible to achieve. In this case, it is desirable to prepare the paint based on the entire wall, then the difference in the shade of one wall from another can be explained by lighting or a special flight of fancy. But I don't think this is an option. After all, you will know what the reason is.
How to apply water-based paint
To paint the walls, you need a certain tool - a set of rollers, brushes and sponges. It all depends on what effect you want to get. If uniform paint application is required, this is done using a roller. Typically, rollers are used that have a soft pile, not very long. However, to create a surface with a texture, rollers are used different and with different piles. Brushes paint small areas and places of contact with other surfaces. Paint of different thicknesses is applied with a sponge, the wall becomes textured, voluminous.
- Paint tray (sold in construction stores, not expensive) is filled with paint by one third of the volume. A strip is drawn along the perimeter of the wall with a brush in order to prevent accidental contamination of the adjacent wall with a roller.
- Next, it is necessary that the roller is completely saturated with paint. To do this, it is dipped into a tray of paint and carried out on any foreign surface (for example, on a sheet of thick cardboard). When the pile on the roller is completely saturated with paint, you can start painting the walls.
- It is better to start painting from the top of the wall. This is done so that drops or drips of paint do not fall on the already painted surface.
How many coats of paint do you need
Paint should be applied in two or even three layers. This is necessary so that the painted surface is even and uniform. And the point here is not the amount of paint, but the fact that all subsequent layers, except for the first, will not be absorbed into the applied putty and primer. Therefore, you should not use a lot of paint for applying the first layer, anyway, the excess paint will drain. It is necessary to apply a small but sufficient amount of paint and rub it.
Each subsequent layer of paint is applied after the previous one is completely dry. During the drying of the paint, in no case should drafts be allowed, and it is also necessary to ensure that the surface to be painted is not contaminated.
Wall painting methods
Often when applying water-based paint on textured surfaces (for example, on decorative plaster) the foundation with the base color is applied first. This is done with a roller having medium, relatively stiff bristles to fill all the recesses, or with a spray gun. Then, with a roller without bristles or a sponge, cover those areas of the texture that protrude with paint that has a slightly different shade. With this technique, volume, depth and the desired visual effect are achieved.
In addition, the necessary texture can be given to the wall with the help of the paint itself. For this purpose, water is not added to the paint, the paint remains thick. If you apply the simplest technique - use a smooth roller, then the surface of the wall will turn out to be somewhat uneven, as if in pimples. However, if you still add a little water, the pattern will be somewhat blurry. But the most amazing effect is achieved when using textured rollers or rollers with glued pieces of material (leather, for example). In addition, you can use special rollers designed to apply applications. In this case, a complex and beautiful pattern is formed on the surface of the wall. It is only necessary to remember that with this method of painting, material consumption increases sharply.
How to paint the walls in the kitchen
Kitchen- a special room and the painting of the walls here has its own characteristics. First, not all walls should be painted completely. On sections of the walls near the gas or electric stove, next to the cutting tables, sinks, it is more expedient to glue tiles. Secondly, the surfaces in the kitchen need periodic wet treatment (preferably with the use of disinfectants), so the paint must be selected as resistant to moisture as possible, in addition, it is advisable to apply a special varnish after painting, but it must have water base(these are sold in hardware stores).
Painting the walls in the bathroom
But in the bathroom with water-based paint, you can paint the walls only if there is a sufficiently effective supply and exhaust ventilation, since this paint does not withstand temperature and humidity fluctuations well. Therefore, it is better to use other materials for decorating the walls in the bathroom. For example, tiles.
In the process of drying water-based paint in any room, drafts, changes in temperature and humidity should be prevented.
Do-it-yourself wall painting with water-based paint
Wall painting is the main step cosmetic repairs. The procedure is quite simple and does not require the involvement of specialists. In order for the painting of the walls with water-based paint to be successful, you need to know how to choose the right everything you need and do the work yourself.
The main rule is not to buy anything on the market. In addition to the risk of purchasing low-quality counterfeit products, materials in such places are stored incorrectly. Water-based compositions freeze at low temperatures, and after defrosting they lose their qualities.
To choose the right water emulsion, you need to pay attention to the following:
Also required Consumables:
- Primer. Provides high level paint adhesion to the wall. In addition, thanks to the use of a primer, smudges will not appear on the walls. It must be made on the same basis as the paint. That is, for acrylic paint, you need an acrylic primer, for silicate - silicate.
- Sandpaper. It will be required for grinding the surface before work.
- Putty. If there are a large number of defects, start and finish putty will be required. If there are few defects, then only the finishing one is enough.
- Polyethylene film. She can cover the floor and bulky furniture, which is difficult to remove from the room, to protect against the ingress of the composition.
- Masking tape. Serves to limit the areas for painting and fixing the film.
Some consumables, such as polyethylene or masking tape, are not mandatory attributes of staining, but it will be difficult to work without them Required Tools
Most often, the compositions are applied to the wall with a roller. There are several types of this tool that are used to paint walls with water-based paint without streaks:
- Foam. The simplest and cheapest type, but due to the fact that the foam rubber absorbs a large number of composition, microscopic bubbles may form on the surface. It is better to opt for a high density roller.
- Velor. Such products are difficult to find in non-specialized stores. Velor is a dense material, so it absorbs a relatively small amount of paint. Thanks to this feature, the tool practically does not spray the composition, but it needs to be dipped into the paint quite often.
- Fur. In this case, we are talking about rollers made of natural or artificial fur. There is practically no difference between them, only natural ones last longer. This option is considered traditional for painting walls.
With the help of a simple tool, you can equip different texture coatings It is also important to determine the size of the tool. In most cases, it is better to choose the longest rollers so that the staining process goes faster. But before buying, it is better to weigh the tool in your hand and take into account that LMB will make it even heavier.
In addition, painting with water-based paint requires brushes for processing hard-to-reach places, a paint tray with a corrugated surface, and a mixer for stirring the material. You also need to prepare a stepladder in advance if the ceilings are high, and work clothes.
Preparatory work
Before painting the walls with water-based paint, it is necessary to prepare the surfaces. The fact is that such paint is not suitable for finishing walls treated with whitewash or oil paint.
Removing old whitewash and paint
If the layer of whitewash is thick, then it will be necessary to make many shallow cuts over the entire area of the wall, moisten the surface with plenty of water and leave for half an hour. After that, wet the coating again and wait until it gets wet. Then simply remove the whitewash with a spatula, and at the end wash the walls with a sponge. If the layer is small, then you can do without notches.
Whitewash after wetting is easily removed with a metal spatula If the walls were previously painted with water-based paint, then the process of its removal is the same as in the case of whitewashing. But if oil paint was used, then removing the coating is more difficult. In most cases, a building hair dryer helps: with its help, the surface is heated, after which the material is scraped off with a spatula.
If the paint is too old, then a hair dryer may not help. Then the technology of removal with the help of chemical washes is used. You need to open all the windows and doors in the apartment to create a draft, put on work clothes, rubber gloves and a respirator. Moisten a rag in the solvent, treat the surface with it, wait the specified time and wash the material off the wall. Repeat this process until a clean base remains.
The safest way to remove oil paint in all respects is to use a building hair dryer. Also, before painting the walls with water-based paint, it is permissible to use mechanical methods paint removal. The easiest is grinding the surface by hand or with a grinder. If you have on hand necessary tools, then you can use a drill with a nozzle in the form of chains or a crown for drilling socket boxes.
Puttying and priming
If the walls are perfectly even and there are not a single crack on them, then this item can be skipped. But, as practice shows, such situations rarely happen, more often preparation is required. It is necessary to tap the wall with a hammer to identify weaknesses, then inspect the surface and open the cracks with a spatula to remove small fragments from them. If large potholes have formed, they are closed cement-sand mortar. Then, the starting putty is applied to the entire area with a spatula, after drying of which the surface must be primed and a thin layer of finishing putty is applied. At the end, the walls are processed sandpaper or grinder.
Perfect alignment walls with putty is a difficult task, so it is better to hire professionals On a note! The primer is applied with a roller mainly in two layers, and the second layer should be applied only after the first has completely dried. In addition to increasing adhesion, this material helps to reduce paint consumption.
Coloring
After the end of all preparatory work and the purchase of materials and tools, you can proceed to the main stage. The following will describe how to properly paint the walls with water-based paint.
Composition preparation
Immediately before starting work, it is necessary to open the paint container and add some water to it so that the paint is not so thick. Next, you need to add color. To carry out this operation with your own hands, you need to have experience, so it is better to tint the composition even in the store. It is better to stir the material with an electric drill and a mixer attachment, but if there is no tool at hand, you can get by with any thin long object. You need to prepare such an amount of paint that is enough to finish one wall, so the difference in shades will be almost imperceptible.
On small volumes, white water-based paint can be tinted manually, but for large areas it is better to use automation, otherwise there will be discrepancies in shades Applying paint with a hand tool
Painting with water-based paints is as follows: the prepared material must be poured into the paint tray, dip the brush into it and paint hard-to-reach places near the ceiling. Then you should wet the roller in the paint and squeeze it on the corrugated surface of the tray. It is better to start painting from above, for this the roller is pressed against the surface and the wall is rolled with it. Thus, the entire surface is painted, and after it dries, a second layer is applied.
A paint cuvette with a corrugated wringing field will significantly save paint Spray gun application
If it was decided to use the apparatus for finishing, then it is recommended to cover the floor with a film so that LKM does not get on it. The technology of work is as follows:
- The paint is poured into a container and the equipment is connected.
- A nozzle is directed to an unnecessary sheet of plywood or cardboard and a button is pressed. This must be done in order for the flow of paint to become uniform.
- Then, directing the nozzle perpendicular to the surface and placing it 30-50 cm from it, you need to press the button and move the device from top to bottom. You should work at a speed of 1 meter in 5 seconds.
- So you need to paint the entire wall, and after drying, apply a second layer perpendicular to the first.
The speed of painting with an airbrush is several times higher manual option but this job requires some skill. On this painting water-based composition finished by hand. If spots appear on the walls after the material dries, another layer must be applied. If this does not help, you will have to remove the coating and carry out the whole procedure again.
Number of coats of paint
According to the technology of work, it is necessary to apply at least two layers of paint. This is primarily due to the fact that part of the paint is absorbed into the surface, which will cause the base to shine through. Therefore, you should not spend a large amount of material on the first layer. It is also important to consider that the next layer is applied only after the previous one has completely dried.
With multi-layer staining, each subsequent layer is superimposed perpendicular to the previous one, but the last layer should be parallel to the light from the window On a note! The number of layers also depends on the color of the base and paint. If the material is lighter than the wall, then at least three layers will be required.
Create a textured surface
Very often, water-based emulsions are used to create a textured painted coating. For these purposes, a viscous material is required that cannot be diluted with water. You will also need a roller with medium-length stiff bristles, a lint-free roller and a sponge. At the first stage, a roller with a hard coat is used, with its help paint is applied to the wall and fills all the pores. Then the protruding parts of the texture are finished with a lint-free roller or sponge. Often, a different color of paint is used.
Simple fleecy rollers can give quite an interesting texture. Creating a texture with a coloring composition
To create a textured surface, you can use paint without first plastering the wall. If only a regular roller is at hand, you need to dip it in a viscous material and quickly roll it over the surface. After drying, you will get a pattern with pores and textured stains. If you first dilute the composition a little, you get a more blurry pattern. Together with the paint, you can use special rollers with flaps or cutouts.
Important! When creating a textured surface, a large amount of material is consumed.
The water-based texture can be applied both manually and with a special roller Features of painting wet rooms
Water-based formulations are easily soluble in water, therefore, during repair work the question arises: how to paint the walls in wet rooms? The main condition for staining with this material is the presence of high-quality forced ventilation. If we are talking about the kitchen, then you can paint only those walls that are located away from the countertop for cooking, gas stove and shells. This area should be covered tiles. After the material has dried, it is recommended to varnish the walls.
For wet rooms, washable water-dispersion compositions based on latex or acrylate are used. As for the bathroom, it is better to use a water-based emulsion only if a shower cabin is installed. The fact is that even with good ventilation in the bathroom, a large amount of steam will form, which negatively affects the coating.
Painting walls with water-based paint with your own hands is a fairly simple procedure. In order for the result to meet expectations, it is enough to follow the above recommendations and carefully read the label on the package. We also recommend watching the video.
