How to paint the walls in a room: from choosing paint and color to working with a roller. Easy Ways to Paint Walls
To know how To to paint walls with water-based paint, you need to familiarize yourself not only with the technology of its application, but also with the procedure for preparing the surfaces to be decorated for it. If you strictly follow all the rules, then you can make sure by your own example that there is nothing super complicated in this process.
Despite to appear on market of numerous innovative finishing materials, wall painting has been and remains the most relevant for modern office premises, and for living rooms in apartments and private houses.
Water-based paint is attractive because it is water-based and does not emit an unpleasant odor when painted. At the same time, it is distinguished by excellent decorative effect - as a result of staining, a pleasant soft matte surface texture is obtained. In addition, using this type of paint, you can create various patterns on the walls that imitate relief, or you can come up with a special texture using auxiliary elements. Typically, this method is used in cases where the wall has irregularities, and there is no way to fix them. An ideal even painting is obtained if the wall is well cleaned and leveled, so all work begins with the preparation of the walls.
Before proceeding with any work related to painting, it is necessary to prepare a working area, as well as tools and accessories, including protective equipment.
To carry out the work, you need to prepare the following tools:
- Construction mixer, but in this case it may well be enough conventional drill with mixing attachment. This will be enough to mix the paint.
- Paint tray - for the convenience of dipping the roller in paint and in order to maximize material savings.
- Roller with a pile of medium length and a long handle - for the convenience of painting walls under the ceiling without the use of additional ladders or goats.
The main tools of the painter - rollers, brushes
- Brushes of different widths - for applying paint in places inaccessible to the roller.
Grater - a tool for leveling the surface of the wall
- Grater for cleaning the walls from the old coating and polishing them.
- Spatulas, brushes or a hard sponge - for cleaning surfaces.
- Wide spatula for leveling walls with putty.
- If the paint will be applied either with a relief pattern or its imitation, then you will need additional tools or homemade elements that will help create the desired texture.
Wall painting materials
It is necessary to prepare in advance and materials, without which it is impossible to do when painting:
The main material is high-quality water-based paint
- Water based paint. It can immediately have a certain color or be white. IN last case you will need a dye that will allow you to choose the desired shade for the paint. It is recommended to mix it yourself, as it becomes possible to paint the walls a little different tone. For example, walls in which window blocks, are illuminated less than other surfaces in the room, so you can prepare a paint tone lighter for them.
- Dye of the selected color.
- Wall primer that will prevent mold stains on the walls and create conditions for good adhesion of paint to surfaces.
- Sandpaper for cleaning and polishing the surface.
- Putty, rough - for repairs and finishing - for the final alignment of the walls.
- Polyethylene film - to protect surfaces that will not be painted from accidental splashes of paint.
- Masking tape-adhesive tape, for fixing protective film on walls and floors, to protect painting areas - if necessary.
- In addition, you need to prepare working clothes and means of protecting the skin and respiratory organs - this is a suitable suit, a respirator or mask, rubber and fabric gloves.
On the choice of paint, or rather, on the criteria that predetermine it when buying, one should dwell in more detail.
Paint selection options
Water emulsion is not at all the same - you need to be able to choose it
Water-based and water-dispersion paints are, perhaps, the best option for decorative painting of surfaces of walls and ceilings in residential premises. This is due to a number of positive qualities of such compositions:
- Such paint is an environmentally friendly product that does not harm human health.
- When working with these paints, there is no sharp unpleasant smell in the room, so work can be carried out even with the windows closed.
- Water-based compositions give a smooth matte surface - a wide scope opens up for the implementation of a wide variety of design projects.
- Sufficiently high moisture permeability of the paint allows it to be used for decorating walls in rooms with high humidity, if the surface is properly prepared.
The most in demand are aqueous emulsions, which are made using acrylic resins. They provide the paint with maximum elasticity and strength, but such compounds have a rather significant cost. Therefore, you can choose compositions that are affordable, but also include acrylic components - these are vinyl acrylic and styrene-acrylic paints.
If the paint contains latex, then after drying the surface acquires water-repellent properties. Such a coating can withstand about a thousand wash cycles.
The water-dispersion version of the paint is somewhat different from the water emulsion. This primarily concerns the main components, which include styrene copolymers, polyacrylates, as well as polyvinyl acetates. These components do not dissolve in water. When applying paint to a surface as it drying out water evaporates, and polymerization of insoluble components occurs on the wall with the formation of a coloring film.
Pigments are included in both aqueous paint compositions - titanium dioxide or zinc oxide are most often used in this capacity - they are introduced to obtain a perfectly white color. In inexpensive paint formulations, instead of these coloring pigments, a chalk component is added, which, in addition, acts as a filler.
When purchasing coloring compounds, you need to pay attention to their characteristics, such as drying time, emulsion viscosity, its consumption, shelf life, storage conditions, specific gravity and others.
- The drying time of the applied paint is from 2.5 to 24 hours, and this parameter depends on the humidity and temperature in the room. Ideal conditions for painting works: temperature of surfaces to be painted +18÷20 degrees, relative air humidity -60-65%.
- The viscosity of the composition is an indicator of the degree of dilution with water. A similar parameter is measured with a viscometer. The simplest viscometer is a funnel of a strictly defined volume with a calibrated drain hole. And the viscosity index is measured in seconds - how long does it take for all the paint to completely flow out. Such a device is often available professional painters Fortunately, it's inexpensive. But data on the viscosity of the composition must be indicated on the packaging. Usually, for applying paint with a roller or brush, a viscosity of 45-50 s is required, and when using a spray gun, not more than 20-25 s.
- Paint consumption per square meter area covered in one layer is 170 ÷ 200 ml. This parameter depends on the surface on which the paint is applied - its friability and absorbency.
- The shelf life of water-based paint is almost always two years from the date of issue, subject to proper storage conditions. These conditions include the temperature of the room, which should not be negative, but the overheating of paintwork materials should not be allowed - the paint should be stored in a cool room with an even temperature
- The specific gravity of one liter of paint is approximately 1.3 kg.
Main specifications water emulsions, established by GOST, are shown in the following table.
| Name of indicator | VD-VA-224 | VD-AK-111 | VD-AK-111r | VD-KCh-183 |
|---|---|---|---|---|
| paint pH | 6,8 - 8,2 | 8,0 - 9,0 | 7,5 - 9,5 | from 8.0 |
| Residual mass of non-volatile substances, % | 53 - 59 | 52 - 57 | 47 - 52 | 52 - 57 |
| Covering ability of the dried film, g/m 2 | 120 | 100 | 80 | 120 |
| Frost resistance of the composition, number of cycles | 5 | 5 | 5 | 5 |

Water-based compositions are easily applied to the prepared surface, but they cannot be used to paint previously coated walls. oil paint, or glossy surface. On the walls, previously covered with an aqueous emulsion, paint made on any basis will fall.
Water-based paint can, in principle, be applied to any surface other than metal, as it can provoke corrosion processes.
Surface preparation
Since the surface of the walls is almost never perfectly flat, and besides, most often some kind of old coating is already present on it, it must first be brought into the proper condition, suitable for painting.
Before starting work on floors and other surfaces that will not be cleaned and painted, a polyethylene film is laid. It must be fixed to the skirting boards with masking tape. By applying this method of protection, you can subsequently save yourself from T intensive cleaning and keep in original condition decorative coating gender.
Wall cleaning
- First you need to remove the old decorative coating from the walls. This process can be carried out with a stiff brush or sponge if the wall, for example, has been covered with whitewash.
The surface is moistened with water, the remains of whitewash are cleaned with spatulas, brushes, and if it gets wet easily, then it is simply washed off using a sponge and a soft cloth.
- If the surface is painted with oil paint, then it can be cleaned with a building hair dryer - this is a long and laborious process, especially If the wall is thinly painted. You can go in other ways, for example, in such a situation there are two ways out - sheathe the walls with drywall, or make notches on them and re-plaster them, creating a smooth surface.
If there are many layers of paint on the wall, and in some places it began to move away, then you will have to clean it off by heating it with a hairdryer and picking it up with a spatula or scraper.
Crack sealing
- After cleaning the walls, it is necessary to conduct the most thorough inspection of them to detect cracks or unstable areas. If they are not repaired before puttying and painting, then they will definitely appear on an already updated wall.
- The detected cracks need to be expanded so that the repair compound penetrates as deep as possible into the thickness of the wall.
- Cracks are expanded with a spatula or grinder with a circle over the stone. Then they are thoroughly cleaned, covered with a deep penetration primer and left to dry for the time specified in the instructions (usually from 4 to 6 hours).
- After drying, the cracks are sealed with putty or one of the polymeric materials, for example, silicone sealant or "liquid nails".
- Closing the cracks, you need to try to remove from the surface of the wall all excess material so that the “patch” is flush with wall surface.
- After complete drying of the repair composition, all walls primed and dry out. If the wall is not smooth enough, then it is leveled with putty, which can be purchased in a pasty state or in a dry mix.
Wall puttying
Whatever putty is used to level the walls, it must be well prepared and brought to the desired consistency. A drill with a mixer nozzle will help with this. The resulting mass must be completely homogeneous, otherwise it will not make the surface smooth.
- Prepared composition is taken from the bucket with a medium-sized spatula or trowel and spread on the edge of a wide spatula. With its help, the leveling mass is applied to the wall with smooth movements. The material can be applied to the surface from the ceiling, floor or corner, the main thing is that the mixture should be distributed in an even layer. All stripes and other flaws remaining from the corners of the tool are immediately smoothed out.
- After the walls are plastered, they are left to dry. This process etc it will go away quickly enough, since the layer of material should be very small, only 2 ÷ 3 mm.
- If the putty lay down successfully, the next step will be to grout it with a grater. If necessary, a second, finishing layer can be applied on top of the first layer, and after drying, proceed to the final grout.
- Grouting is done with light circular movements counterclockwise until the surface is perfectly even.
- After completing these works and achieving the desired result, it would be nice to vacuum the walls thoroughly from putty dust, but so as not to leave accidental scratches with the brush of the vacuum cleaner.
- Next, a primer is applied to all prepared surfaces, which must be given 5 ÷ 6 hours for complete absorption into the walls and drying. The primer may have White color Or be transparent. It is best to apply it with a roller, but it can also be applied with a wide brush, especially in hard-to-reach areas (at corners or in places where pipes pass, etc.)
Then you can proceed to the preparation of the paint.
Paint preparation and color selection
One of the difficult moments correct selection colors
When you open a can of paint, you can see that its consistency is usually quite thick. The composition of this viscosity is well suited for creating embossed wall paintings, but for painting it is still thick. Therefore, after intensive mixing of the emulsion, it can be slightly diluted with water to the desired state.
- Water is added in very small amounts to prevent over-dilution to a condition unsuitable for painting vertical surfaces.
- Using different colors and shades of water emulsion, you can create amazing room interiors. However, in order to realize what was conceived, you will have to “conjure” over white paint by adding the selected color to it, and the more it is added, the brighter the paint will turn out.
Color is added gradually, and after each addition, the paint is thoroughly mixed.
- In order to get the same color for all surfaces of the room, you need to immediately determine how much color is added to each can or to a bucket of paint of a strictly defined volume. And even better - prepare at once such an amount of paint of the desired color, which is enough for all surfaces of the room.
The only retreat that is recommended is to cover the wall on which the window is located with a coloring composition one or two tones lighter than the other three walls. This combination will visually expand the space of the room.
- It would be nice to leave some of the made paint in reserve, so that if the walls are worn in some places, they can be brought back to their proper form. Preparing exactly the same color later is a very difficult task.
- If, according to the project, several colors of paint will be used in the room, then masking tape is indispensable. She stands out separate part wall that is painted in one color. After the final drying of this area, the tape is glued on the other side of the border, and the second selected color is applied next to it, and so on. In this way, even quite complex mosaic patterns are performed.

wall painting
- Water-based paint is applied in two to three layers, depending on the degree of absorption of the surface. To reduce this absorption capacity, the walls need to be very well prime, as already mentioned above.
- The prepared paint is poured in a small amount into a clean tray, from which it is convenient to pick it up both with a brush and a roller. In addition, the ribbed surface of this paint bath helps to save material, as it is perfectly squeezed out of excess paint taken on a roller or brush.
- The roller is dipped in paint and scrolled in it so that its entire “fur coat” is saturated with the composition evenly. The first stroke with a roller is best done on a sheet of cardboard. If it will be seen that the roller is well impregnated, then you can install a long handle into it and start painting over the wall, starting from the top. The smudges formed in this case, which fell on the unpainted bottom of the wall, in the process of work will be compared and rolled out with a roller.
Large areas are covered with a roller, and corners or places inaccessible to its penetration are painted with a brush.
- Wall painting should be carried out in two or three layers, always after each of them has dried - only then will a uniform paint coating be obtained.
- During the drying of the coating, it is necessary to protect the room from the occurrence of drafts, as they can spoil the evenness of the color of the walls, due to the fact that the areas will dry out unevenly under such conditions.
- On a flat and dry surface of painted walls, often through a stencil or with a special nozzle on a roller, drawings of a different color of paint can be applied. With this decor, you can revive a boring plain wall.
An interesting surface texture can also be given with the help of the simplest devices - sponges, home-made rollers, crumpled polyethylene, etc.
- Another option for creating a visual texture it can be applied to a dried surface of paint of a different tone with a sponge compressed polyethylene film or other homemade devices.
- First coat textured surface produced by the base color. Such a layer should paint over the entire plane perfectly evenly. In this case, you can use a spray gun to cover the main layer - it will help the paint penetrate into all the deepest places in the relief.
- Further, paint is taken two or three tones lighter than the base color, and preferably a much thicker consistency. It is typed on a clean roller, which, without pressure, is carried out only on the top layer of the textured pattern. This must be done very carefully, as you can spoil the first base layer and will have to make some difficult adjustments.

When choosing a textured type of staining, you need to take into account that almost twice as much paint will be required, since the top textured or top layers will be applied with a thick, undiluted paint composition.
The work of painting the walls can be called creative, since with the help of water-based compositions you can create works of art - you just have to turn on your imagination and imagine the room in the final version.
If there are no ideas, then you just need to choose a color that will suit all the residents of the house, and get to work. It is not difficult to paint a finished flat surface, the main thing is to make the walls smooth, but this — enough labour intensive process . The creative part of decorating the room will be easy, as things will go to completion and receive an updated, self-created interior.
Video: how to paint walls with water-based paint
Do you have a renovation in your apartment, work with plaster requires a special skill, and there is no desire to glue wallpaper? In this case, the walls can simply be painted with special paint. It is not difficult, and the end result will exceed all expectations, the main thing is not to rush and follow our instructions.
The choice of paint for the apartment and house
The choice of paint should be guided by its safety, durability and ease of application. Therefore, compositions for internal works differ from paints for external use and are represented by the following varieties.
Water-based paints received wide use due to its harmlessness to others, the absence of an unpleasant odor and fast drying. Usually these are compositions based on polyvinyl acetate (known as PVA).
Such paint is well applied by roller or through a sprayer, has excellent hiding power - 1-2 layers are enough to obtain a stable color.
After drying, a polymer film is formed, which has a vapor-permeable property, that is, the wall “breathes”. It is very easy to tint, the number of shades depends only on your imagination.
Water-based paint is the cheapest paint on the market, which makes it the leader in use, despite serious drawbacks. Firstly, it is not resistant to mechanical stress and quickly scuffs out in places of frequent contact with the wall (corridor, hallway, storage room). Secondly, the applied layer of paint is very thin and is not able to hide defects on the walls, for which you have to specially prepare the surface. Thirdly, he is afraid of water. You can wipe the wall several times with a damp cloth, if you do this more often, ugly stains will remain on the walls.
Silicone water-dispersed. Such dyes can be called ideal for walls. After drying, a durable film remains on the surface of the walls, which is not afraid of moisture and damage. You can wash it as much as you like, and most importantly, it has the ability to tighten cracks of 2-3 mm, making the surface very even and smooth, even without pre-treatment.
The surface is dust-repellent, with good vapor permeability, is not afraid of ultraviolet radiation, which determines its use in rooms with high humidity. Flaw silicone paint- high price, this explains its low prevalence.
Acrylic water-dispersed. Excellent balanced paint in the middle price range, has virtually no flaws. It has good hiding power, is easily tinted, paints over small cracks, does not fade and is sufficiently resistant to abrasion. A wall painted with acrylic composition can even be washed, vapor permeability is slightly worse than water-based paint. In terms of price / quality ratio, this is best paint for ceiling and walls today.
Alkyd paint
Alkyd compounds. These are paints based on polyester alkyd resins and organic solvents. The consistency is similar to oil, but differ in characteristics.
They need prepared Smooth surface, wooden and metal surfaces are painted very well - doors, windows, heating radiators, pipes.
Alkyd enamels are not afraid of moisture, high temperatures, sun rays. These paints are among the cheapest, and the most famous enamel on our market is PF-115.
Their disadvantage is serious and is associated with the content of organic solvents in the base - it can be acetone, thinner, white spirit, gasoline, turpentine. When drying and painting, care must be taken and work in a well-ventilated area. Light tones fade over time and acquire a touch of yellowness.
Silicate dyes or liquid glass. Wall painting in the kitchen, hallway, bathroom can be done using this technology. The advantages are obvious: the coating is very durable, mold and fungus do not start on it, the painted wall looks very impressive.
There are also disadvantages. Firstly, the composition before drying is very harmful and work with it must be carried out in a respirator and protective equipment. Secondly, tinting is done with special mineral pigments, which narrows the color gamut. Thirdly, this type of paint does not lie on top of another paint, only on a specially prepared wall, silicate paint also cannot be painted with another type of paint.
Textured decorative paint
Textured decorative paints. Appeared not so long ago, but managed to become quite popular. When applied to the wall, this paint forms a chaotic decorative and embossed pattern. The secret lies in the water-dispersed acrylic composition with various additives - sand, cellulose and mineral fibers.
The application technology may differ depending on the density of the solution - from a spatula to an airbrush. On sale you can find paints with the effect of fabric, suede, mother-of-pearl, artificial aging.
Decorative painting of the walls in the apartment
On the network you can find a lot of color options for any residential area. Special tinting tables, which are used by professional designers, will help you choose the right colors for the room.
Groups combine shades that make a combination different colors harmonious. The main options for painting walls:
Classic way
Classic way - horizontal division into two, rarely three zones. The bottom is stained dark paint, top and ceiling - light.
This combination allows you to visually increase the height of the ceiling and gives a clear division into the working area and the free space area.
The junction of two colors can be decorated with a molding, a plinth (country or ethno style), or simply make a perfectly even line using masking tape (hi-tech or minimalism). There is a combined painting of the walls, when the lower part is glued textured wallpaper, and the upper half is painted with plain paint.
Accent method
Emphasizing a separate section of the wall or the entire wall. Now it's fashion trend. There may be two options: highlighting the wall with the same color, but more intense, or another color is taken from possibly compatible ones.
This method is good for its simplicity, but at the same time grace. Sharp contrasts are good in hallways, living rooms, children's rooms. For the bedroom, it is better to choose less intense shades. Using this method, you can easily highlight any area in the room, for example, a place for a TV, a workplace, a dressing room, etc.
Wide vertical or horizontal stripe
It is used on a monochromatic coating at eye level. This technique is resorted to if you need to focus on other elements - paintings, medals, exhibits. The color of the stripe should be combined with the main color and not cause irritation. A transition from one color to another within the same band is allowed.
striped walls
Striped walls are another interesting design technique requiring careful study. It is worth using it for one or two walls and with the obligatory repetition colors stripes in other interior details.
Stripes can be vertical and horizontal, each has its own visual effect. It is interesting to get a combination of glossy and matte stripes of the same shade.
Highlight interior details
This technique is used to designate various recesses, niches, shelves, frames. You can also select individual areas near working area in the kitchen, washing in the bathroom, hallway.
You can emphasize by highlighting bright color all corners and edges of walls. This technique visually increases the volume of the room.
Wall preparation and painting
So, the project is selected, the paint is bought, you can get to work. We start with the fact that we free up access to the surfaces to be painted as much as possible. We take out the furniture or move it to the center, covering it with polyethylene. We calculate the area of all sections of the wall where the paint will be applied and its amount according to the consumption rates on the label. Now you can work directly with the walls.
- We remove old paint, wallpaper, plaster. If the ceiling has already been painted, then smudges from the ceiling. This work is best done in a respirator so as not to swallow the smallest dust.
- Then, using a spatula, you need to level the surface of the wall and repair all cracks and depressions with putty. Putty must be selected for the intended type of paint.
- After the final drying of the putty, the wall must be sanded. We need a wooden block or special grater, around which the skin or grinding mesh is wrapped. Everything superfluous is removed from the walls with smooth circular movements. After this operation, be sure to remove all dust from the surface with a vacuum cleaner or a dry cloth.
- The primer of the entire surface of the wall is needed to better set the paint to the surface and reduce the consumption of the coloring solution. It is advisable to purchase a primer under concrete type paints.
- Wall painting. You can paint with a roller or spray gun in 2-3 layers. Each subsequent layer must be perpendicular to the previous one. The first layer is up - down, the second from the right - to the left. This technique allows you to achieve uniform application and avoid smudges.
- To avoid smudges, do not take too much paint at a time. So the brush is dipped to half the bristles, the roller is slightly less than half and squeezed out in a cuvette. First, 3-4 stripes are applied, which are then shaded over the entire surface.
- The paint should not be very liquid (spots will form and it will turn out to be unpainted) or very thick - it is very difficult to work with it, and the consumption can be unpleasantly surprising.
- We apply oil paints based on drying oil with soft hair brushes. Alkyd enamels allow the use of bristles.
- Always use masking tape to get clear boundaries and coloring complex contours. Volumetric decorative elements are painted in stages, starting with internal elements and moving to the outside. Each previous layer is protected masking tape from accidental staining.
- We paint large areas in stages, using natural boundaries - skirting boards, corners, wall joints.
- The combination of several shades occurs as follows. We mark the borders of the stripes with a pencil and glue masking tape along them. To get a clear line, you can apply a colorless varnish on the edge of the adhesive tape. We remove the adhesive tape after the wall has completely dried.
Features of painting the walls in the bathroom and in the kitchen
These rooms have one thing in common - high humidity and the need for regular wet cleaning of surfaces. It is preferable to use acrylic paints with fungicidal additives or alkyd enamels. Glossy is preferable to rough and matte, provided that the surfaces are well prepared.
Puttying is carried out with cement-sand-based mixtures that are not afraid of moisture, they are inexpensive and allow significant differences to be brought to zero. After drying, after 2-3 days, the entire surface is sanded with sandpaper with varying degrees grit until a smooth uniform surface is obtained. Now you can apply a primer with an antibacterial property. The preliminary primer will fill in all micropores and give the wall additional smoothness.
Coloring is done in 2 layers from the corners to the middle with the complete drying of the previous one. The second layer can be applied with a conventional roller.
We must inspect the hardened paint under a strong light source, unpainted areas are polished and painted over.
Methods for painting a brick wall
Although the brick itself is very beautiful and aesthetic, sometimes it may be necessary to paint the brick wall. The main difficulty lies in the heterogeneity brickwork- seams crack over time and do not hold paint well. To do this, all joints are pre-sealed with cement and plaster. Lime stains and other contaminants are removed, the surface is washed, degreased with a solvent and dried.
The primer is required, it will fill all the pores and bind the solution in the cracks, improve the adhesion of the paint. It is necessary to apply a layer of 1-2 mm evenly over the entire surface. We take ordinary water-based acrylic paint, but the roller and brush should be as rigid as possible - due to irregularities, they will wear out more. Staining with silicate and latex formulations. In some cases, clear varnish may be used to emphasize the texture of the brickwork.
Today, wall painting is again popular with us. For a long time we managed with wallpaper, but now it has become clear that coloring has many advantages: firstly, with the help of colors you can choose the perfect suitable shade paint, which is not available if the choice is made in favor of colored wallpaper. Secondly, surface painting is much simpler and affordable way finishing as opposed to wallpapering. Anyone can handle wall painting.
What paint to paint the walls in the room?
Best suited for painting walls in rooms and kitchens water dispersion (water emulsion) paint. Water dispersion paints consist of water and very fine polymer particles. When the paint applied to the surface dries, all the moisture leaves and only the film remains. Moreover, the film is reliable, withstanding even increased loads, not afraid of moisture and sunlight. Walls painted with such paint can be washed even with the use of detergents.
Water-dispersion paint is applied to concrete and plasterboard walls, as well as to partitions made of plywood and wood-like materials. For coloring metal surfaces This paint doesn't work!
Water dispersion paint is different depending on the base. Paint base can be acrylate, latex, polyvinyl acetate . The characteristics of the paint after it dries also depend on the base. So, for example, acrylate paints are generally not afraid of anything - neither moisture, nor temperature changes, nor mechanical influences. Polyvinyl acetate fits perfectly even on not the most ideal surfaces, which can subsequently not only be washed, but even cleaned. Thus, water-dispersion paints are suitable for painting walls not only in rooms and kitchens, but also in bathrooms.
Water-dispersion paints almost do not smell, and this has great importance when renovations are underway in an already occupied apartment. Water-dispersion paints can be diluted with water - they are liquid, and therefore easy to apply. There are no unpainted areas. The paint dries quickly - just a few hours until it dries completely.
wall paint color
Water-dispersion paints are already sold in color or white. IN white paint you can add color and achieve not only the desired color, but also the desired hue, depth and saturation.
It is important to immediately mix with the color scheme the amount of paint that is needed to paint all the walls of the room, otherwise it is unlikely that the shade will be exactly repeated, and the walls will be different in shades.
After complete drying, the paint changes color slightly. Therefore, it is worth testing small area walls or on a piece of wallpaper for painting, which are pasted over the walls. You should wait until it dries completely, and then evaluate the result (it is advisable to attach the painted wallpaper sheet to the wall or even fix it on it). It is worth waiting for twilight and darkness and look at the color in light twilight and under electric light. So you can be sure that this shade suits you. If you want a lighter shade, add a little white paint to the already diluted one. Well, if you need a richer shade, enter a little more color.
Preparing walls for painting
The easiest option is to pre-paste the walls with wallpaper for painting. Ideal for thick non-woven wallpaper or glass wallpaper for painting, which has the effect of leveling the walls. By choosing the option of painting the walls according to the wallpaper, you can avoid a lot of complex work to bring the walls into a perfectly even and smooth state.
It must be remembered that the paint does not hide the defects of the walls, but rather emphasizes them! Therefore, before painting the wall must be brought to an excellent or close to that condition.
If the walls have already been leveled and painted with water-based paint, it will be enough to simply wash them with a fat-dissolving detergent, wait until it dries completely, then prime the surface 2-3 times. For the last time, you can add a little paint to the primer, which will paint the walls. Such preparation will be enough: the walls are clean and primed, which means that the paint will lie evenly and stick well (the primer improves adhesiveness).
Preparing walls for painting from scratch
If you decide to paint the walls without wallpapering and Not over old paint, start preparing the walls by removing the old finish: remove old wallpaper or remove paint. Special solvents are sold to remove old paint from walls.
Next, the surface must be cleaned: wash concrete walls with detergent, and drywall with a slightly damp cloth. Wait for it to dry. After that, the surface must be sanded using pumice stone or sandpaper. Dust the surface again and apply the first coat of primer.
Inspect the walls for cracks, dents and other defects and irregularities. All defects must be repaired with putty. This is called coarse sanding. When the putty dries, it is necessary to grind the treated areas, which is carried out using sandpaper or metal mesh.
The next stage is the final puttying, that is, leveling the entire surface of the walls and thereby creating smooth surface. After the putty dries, full sanding is necessary again. After removing the dust after grinding, you need to apply a primer.

For an ideal result, the primer should be applied 2-3 times - then the surface will be even smoother. And most importantly - the paint fits perfectly on a well-prepared and primed surface several times.
If the walls are plasterboard, Special attention given to the seams. The places of screwed screws and self-tapping screws are puttied quite easily, but the joints of the plates are more difficult to close. Putty in these places is smoothed out especially carefully. Then, after drying, it is very carefully polished.
Do not make the putty too thick - it will be difficult to work with. At the same time, too liquid putty will shrink after drying, which may cause cracks. Make the putty thicker, but so that it is most convenient for you to apply it.
As for the choice of primer, paint manufacturers often offer appropriate primers specifically for one or another of their paints. We recommend buying a primer along with paint.
How to paint the walls? Technology
1. We glue the masking tape. Use masking tape to mark the edges of the surface to be painted. This is very important: the tape will protect surfaces that should not be painted from staining. And it will be more convenient for you, because. you will not be afraid to accidentally go abroad. Stick the tape on door frames and platbands, borders window openings, sockets, switches, floor plinths, as well as on the border of the wall and ceiling.
2. We breed paint. Water-dispersion paint is applied to the walls in at least 2 layers. To apply the first layer, it is better to make the paint thinner. Water-based paint can almost always be diluted with water in the proportion: 1 part water to 9 parts paint. This will allow you to paint the walls more evenly and subtly.
Before you start painting the walls, dilute the paint with water, mix it well. Next, put on goggles and pour some of the paint into the paint tray.
3. We work with a brush. Start painting the walls with a brush in places that are hard to reach for the roller. This is also necessary to protect those surfaces that do not need to be painted (for example, ceilings, window openings, etc.). Paint with a brush the junction of the ceiling and walls, walls and floor, corners, borders with windows, doors, as well as places near switches, sockets, etc. The brush should be dipped into the paint for a third of the length of the hair, then let the paint drain a little.
4. We arm ourselves with a roller. The roller must be checked in advance for the strength of fastening hairs or villi. If they crumble and fall out, take another roller. Dip the roller in the paint tray and roll it so that the entire surface is soaked with paint. Note that you need to roll a roller dipped in paint not along the wall, but along something else: a tray or, if it is not there, a piece of linoleum, chipboard, etc.
5. Start painting the wall. Start painting the wall from top to bottom, making crosswise movements. If you paint the walls not diagonally, but even horizontal or vertical stripes, you can, firstly, leave a lot of unpainted places, and secondly, after drying, traces, stripes, prints can be noticeable.
The paint is applied to the walls with cross and W-shaped movements.
Choose a small area and paint it from top to bottom, then move on to next section. So gradually the whole wall will be painted. Do not forget to periodically dip the roller in the paint and roll it over the tray.
It is better to start painting the walls from the window, that is, in the direction of the fall of the sun's rays.
When the wall is completely painted, move with the brush to another wall to paint its junction with the ceiling and floor, corners and other hard-to-reach places. After that, arm yourself with a roller again.
6. Apply a second coat of paint. The second coat of paint can be applied after about 4 hours. But look at the exact time on the bucket of paint - the manufacturer must indicate such information. The second layer is usually applied with paint not diluted with water. The layer is applied in the same way as the first.
7. Finishing work. After complete drying, you need to remove the masking tape and, if necessary, paint over with a brush the remaining unpainted places at the joints of the walls with other surfaces.
If necessary, a third layer can be applied, but do not overdo it.
Do not be alarmed if immediately after painting you see irregularities, spots, stains, etc. on the wall. As it dries, the color will even out. Roll the roller on the wall carefully, removing excess paint with it, if any lay on the wall.
To paint the wall behind the radiator, use either a long-handled brush or a small, long-handled roller. The battery can be wrapped in plastic wrap in advance.
Another tip for newbies: start painting the wall that will be maximally covered by furniture, curtains or wall decor. You need a workout. It is better to start it where the results will be subtle. Don't worry: water-based paint is good because it lays down easily. Even beginners get good results. Good luck with your painting work!

The modern market of finishing materials offers a lot of options for final wall decoration for every taste and budget. Someone prefers to paste over the walls with wallpaper, someone prefers to decorate interior decorative tiles or wall panels from PVC. But the most popular method of finishing the walls in the apartment is to paint them.
Paint - very high quality and relatively inexpensive material. In addition, there is a fairly wide selection various colors and shades. The paint does not fade and does not fade over time, it is easy to wash, and if desired, you can always easily repaint it in a different color.
How to prepare walls for painting?
First of all, you need to understand that no wall defects can be masked by painting. Therefore, in order to obtain a beautiful and high-quality result, attention should be paid to careful preparation walls.
To begin with, the walls must be cleaned of the previous coating (if any). Plastered walls are examined for all kinds of defects and internal cavities. If there are any, the walls are freed from the old layer of plaster and puttied again.
Next, the surface of the wall is primed. To ensure good adhesion of the primer to the wall surface, a high penetration primer is recommended. To disinfect walls and remove mold spores, it is advisable to use a primer with an antibacterial composition. This is especially true for rooms with high humidity. The primed surface is left to dry for 5-6 hours.
After priming, you can start leveling the walls. For this, the walls are putty. The most commonly used gypsum-based putty. The dry mix, which is prepared immediately before use, will be cheaper. Putty is applied with a special tool - a spatula. After puttying, the walls are thoroughly dried. It is recommended to take at least a day for this in order to avoid the appearance of surface defects during its further processing.
The final stage of preparing the walls for painting includes covering the wall with a special putty called satengypsum. This is a very fine grind. It is applied with a layer of 1-2 mm, after which it is also dried. The smoothness of the wall is given with fine-grained sandpaper.
What influences the choice of paint?
Now that you have prepared the walls, you can start painting them. What paints are used to decorate the walls? It all depends on the functions that the room performs.
So, for example, rooms with high humidity are best treated with moisture-resistant paint. For kitchens, durable paints that can withstand frequent wet cleaning and have good wear resistance are more suitable. And for living quarters, especially bedrooms and children's rooms, it is important to use eco-friendly and moisture-permeable paint. If the walls are imperfectly processed, then it is better to use matte paint to hide minor defects.
For people prone to allergic and pulmonary diseases, as well as for children, it is recommended to use special paint with high environmental safety. Typically, manufacturers mark such paint with special signs.
Types of paints
Water based paint- the undisputed leader in wall coverings. It is an aqueous suspension of pigments. It is easy to apply, dries quickly and is completely non-toxic. Due to its moisture permeability, it allows the walls to "breathe". In addition, the walls covered with "water emulsion" are easy to put in order with a sponge and detergents.
acrylic paint– elastic, waterproof and has a large selection of colors. In addition, it has high abrasion resistance. It dries quickly upon application and does not leave an unpleasant odor. Walls painted with such paint acquire a beautiful matte look.
latex paint- usually used for painting wallpaper, as it has a high resistance to abrasion. Unfortunately, it is waterproof, so the walls stop "breathing", which adversely affects the ecological climate of housing. Recommended for use in special rooms where frequent washing of walls is required.
silicone paint- is considered one of the best interior coatings. This paint is very plastic, which allows you to hide minor imperfections in the walls. It has good vapor permeability, which makes it environmentally friendly. In addition, it includes antibacterial components that protect the walls from mold. It can be applied to any surface.
Oil paint - suitable only for well-ventilated rooms due to its specific smell. Depending on the consistency, it is either ready-to-use or to be diluted with drying oil.
Application rules
It should be noted that after drying, the paint may slightly change its shade, so first test the selected paint on a small section of the wall or a piece of wallpaper for painting. Wait for it to dry completely and evaluate the result. Also note how the resulting shade looks when artificial lighting and at dusk. So you can definitely understand if it is right for you.
Before treating the walls with paint, cover the surface with masking tape - to mark the boundaries of the surface to be painted. Such a tape will save those places that you do not plan to paint from accidental splashing of paint.
The surface should be painted from top to bottom, with diagonal movements. When making parallel vertical movements, the surface can be painted over unevenly, which will be visible when it dries.
It should not cover the entire surface with the tool, but do it gradually, in sections. When you finish one section, move on to the next.
Painting the walls should start from the window, that is, in the direction of the fall of the sun's rays.
Wall joints with ceiling, floor, corners, etc. hard-to-reach places should be painted over with a brush. The surfaces themselves are roller.
If you are new to the repair business, then start painting the wall that will be filled with furniture or curtains to the maximum. So you fill your hand and practice before painting the surface that is “in sight”.
Do not be upset if immediately after painting the wall looks unpresentable, stains, stains and bumps are visible on it. If you did everything correctly, then as it dries, all these “defects” will gradually disappear, and the color will even out.
