The technique of painting the ceiling with water-based paint over old paint. Options for painting walls with water-based paint
Painting requires care, attention and the right choice of a suitable suspension. To date most widespread received a water-based paint, which compares favorably with its counterparts in many advantages.
But how versatile is it and what surfaces is it suitable for? This is what we will try to understand in this article.
General provisions
To begin with, let's define what water-dispersion paint is.
Structure
The water emulsion consists of ordinary water in which binders and color pigments are dispersed. After being applied to the surface, H 2 O molecules evaporate, leaving a durable polymer layer of the desired shade. It is also possible the presence of various modifying additives that endow the solution with additional properties.
Advantages
After getting acquainted with strengths water emulsion, it will become much easier to determine the types of materials that go well with it.
- Full environmental friendliness. As can be seen from its structure, at the moment of solidification, only absolutely safe water is released. That allows the use of this solution even in the children's room.
- Low price. The absence of expensive solvents in the composition makes water-based paint cheaper than most similar suspensions.
- Variety of possible colors. It is also possible to mix available colors to obtain rare original shades.
- Ease of manual operation. Does not form streaks, creates a uniform even layer.
- High resistance to high humidity, abrasion, temperature extremes, alkaline attack, physical damage and ultraviolet radiation .
Tip: with increased aggression environment it is recommended to use a variety of acrylic water-dispersion paint for finishing work.
Although it is more expensive, the acrylates acting as binders in its structure significantly increase all technical characteristics, making the coating even more reliable and durable.
- Ease of maintenance. The instruction manual allows the use of household chemicals during cleaning, making it easy to get rid of any dirt stains.
- High vapor permeability. Which is important for many types of materials that need to "breathe".
- Elasticity. Does not crack even if cracks appear in the base material. It is successfully used for processing small and moving parts of furniture or interior.
- Easily rinses off hands and tools with ordinary soap.
- Long service life. With proper care reaches ten years.
Types of matching surfaces
Based on the structural features of the water emulsion and its characteristic advantages, we can conclude that it is suitable for almost all types of surfaces.
But let's look at individual cases in more detail:
- Wood. Is it possible to paint a tree water-based paint? Quite, the water emulsion will perfectly protect the wood from the harmful effects of excessive moisture, which will favorably affect the increase in its service life.
- Oil suspension. Is it possible to paint with water-based paint over oil? The fact is that such a surface is covered with the thinnest layer of acids and oils, which prevent the water-based emulsion from moistening the base with high quality. As a result, the adhesion is very weak, and the result is very far from high-quality.
So before painting with water-based paint, it is necessary to completely clean the area to be treated from traces of the old paintwork material.
Tip: When removing old oil slurry, it is recommended to use an industrial hair dryer.
Under the influence of hot air, the paint layer will swell and peel off, which will greatly simplify its elimination.
- Lime. Is it possible to paint with water-based paint on lime? Yes, since it has a sufficient level of steam transmission, which is necessary condition for the successful exploitation of lime and plastered surfaces. But at the same time, it is advisable to start painting no earlier than a month after finishing the finishing work. This will make it possible to have time to ripen the facing material as much as possible.
- Iron. Is it possible to paint metal with water-based paint? As we already know, the basis of the solution in question is water. And iron is susceptible to corrosion. That is, such painting can cause the occurrence and spread of rust under the finishing layer.
To prevent this from happening, it is necessary to make a preliminary deep penetration, which will create a polymer layer that reliably protects steel from contact with water particles of the emulsion.
- Brick and concrete. How to paint with water-based paint brick or concrete surface? It can be done. It goes well with these materials, both on the inside and outside of the building.
Conclusion
Water-based paint outperforms its competitors due to the peculiarities of its structure.
The presence of a water base guarantees it:
- environmental cleanliness;
- high moisture resistance;
- fire safety;
- affordable cost;
- many other undeniable and very important advantages.
It is combined with almost any material, although some require pre-treatment other special compounds.
The video in this article can provide you Additional information related to the material under consideration. A water-based emulsion is the best choice for carrying out at the moment from the available paints and varnishes.
There are many different ways to decorate a room. One of the most common is the painting of walls and ceilings with water-based compositions. The popularity of this coating is due to its distinctive features: this paint does not have a strong chemical odor, dries quickly, is non-toxic, and is not afraid of washing and cleaning. In addition, thanks to tinting, you can get almost any shade.
However, water-based paint, like any other material, has its own characteristics and special application requirements.
Application features
Water emulsion is the definition large group dyes, which are based on an aqueous emulsion. All of them have different characteristics and their application features. However, there are a number of features that unite all types of dyes: so the coatings do not fade, do not crack, are easy to apply and dry quickly, are quite wear-resistant, odorless and environmentally friendly.
Almost any surface can be painted, however, due to the high water content, water emulsion is not used for painting metal and ceramics, since it is from these materials that it simply drains.
It is also important to note that this kind of paint has a very low price. In addition, in large retail outlets, you can tint the base for free or at a low cost, which will help you get almost any desired color.
With all the advantages, there is also a significant disadvantage. Using a water emulsion in a very wet rooms with a low temperature or its frequent changes, for example in the bathroom, as well as making mistakes in dilution, application or other application technologies, you can encounter a rather unpleasant consequence - a fungus.
Adding special antifungal compounds to the paint will help to avoid this. Many modern manufacturers initially add antifungal agents to water-based paint.
What options for water-based dyes are offered on the market today.
- Acrylic water-based paint. This option is by far the most common option used for painting almost any surface. Distinctive feature of such paint is its increased moisture resistance. Surfaces painted with such compositions can be washed with any cleaning agents. Painting can be done even on metal surfaces which must first be well primed. Acrylic paint is perfect option for inexperienced users, because it does not flow and lays down without gaps, and can also be applied in any convenient way: with a roller or brush.
- The cheapest option, which is used exclusively in dry rooms, is polyvinyl acetate aqueous emulsion. Such a coating can quickly crack and wear off even with a slight mechanical impact.
- As opposed to polyvinyl acetate, there is the most expensive representative of the line - latex dye. This option has the maximum level of moisture resistance, so it is suitable for painting the entire room.
Most often, however, it is used for coloring streams. When using such a coating, you can get both matte and glossy finish. You can find out about the type of coating by special markings on the packaging.
Polyvinyl acetate
Latex
- Least susceptible to pollution silicone coating. It can be applied to plaster, over wallpaper, drywall, plywood, fiberboard and other surfaces. In addition, both paper and any kind of vinyl wallpaper can be painted.
- A variant of glass fiber can be obtained by painting the surface silicate water emulsion. On a primed drywall or wood surface, a silicate coating can last up to 25 years.
When stained with any type of water emulsion it is necessary first of all to calculate the required amount of paint. This is especially true if the paint is pre-tinted. Mixture consumption per 1 sq. the meter of the room can be found in the annotation to the product. In addition to the required amount, it is worth laying 10-15% of the total mass plus - just in case.
Since the layer of paint is usually extremely thin, it is necessary to carefully level the surface to be painted, having previously removed old coatings, unless painting is to be done over.
How to dilute the paint?
One of the most important conditions comfortable and economical application of water-based paint is to bring it to the required viscosity. Too liquid paint will drain, will not be able to qualitatively paint over the surface and fill in the existing small irregularities or roughness, and too thick will have a very large consumption of material per square meter. surface meter. Besides, too thick a layer of paint may cause the material to peel off.
So how to dilute the paint, if its consistency requires it? The easiest breeding method is by far the most plain water. There are also special dilution solutions, but water is the most accessible and simplest material.
In order to dilute the paint, you need to take a clean container, the size of which will depend on the parameters of the surface and the amount of paint that will be needed for painting. With a large consumption of paint, it can be diluted directly in the factory container.
The dilution process itself is extremely simple: it is necessary to gradually add additional water to the paint, while the mixture must be thoroughly mixed. It is best to mix the components with the most suitable device for this - a wooden stick. The proportions of water emulsion dilution with water will be determined by the initial density of the paint.
A special recipe exists for diluting heavily thickened paint, which has already acquired the consistency of a paste. Here, the same water with which it needs to be diluted will help to make it again suitable for work. Only under these circumstances should it be heated.
Sometimes, to obtain a colored water emulsion of the required consistency, there is no need to dilute it with water - it is enough to carry out the tinting process. The procedure will be similar to the one described earlier.
- In clean dishes, you need to add the amount of paint necessary to color the entire selected area, otherwise it can be extremely difficult to get into color with additional tinting.
- Then all this paint must be mixed until smooth with a clean stick or with a construction mixer.
- Without ceasing to interfere, drop by drop, you need to start introducing the dye. Continue such actions should be until the paint has acquired the desired shade.
In addition, during the tinting process, you can add a special pigment that will help make the selected pearlescent paint. This action will help to achieve a very interesting end result.
Preparatory work
Irregularities, streaks, stains or other blotches can spoil the whole impression of fresh coloring. To prevent this from happening, it is important proper preparation surfaces for coating.
First of all you need to completely clean the surface of old coatings, be it wallpaper or paint. If the wallpaper does not peel off well, you can help yourself by wetting it with water from a spray bottle. After the water is absorbed, the wallpaper will easily move away from the walls or ceiling.
If the prepared plane has various irregularities, the surface should be puttied / plastered and primed. Do not forget that before painting you need to let the putty dry completely.
It must be remembered that, depending on the type of plaster and its manufacturer, the period of complete drying of the applied layer can be up to 30 days, so it is necessary to carefully study the properties of the mixtures before plastering or puttying the surface with them.
The prepared surface should be free from dust, stains and possible dirt particles, if necessary, the walls can be washed with a solution of water with the addition of a mild cleaning agent. After cleaning, it is important to wait until the surface is completely dry.
When the surface is as clean and dry as possible, you can proceed to the next final stage before painting - primer. Most often, universal polymer compositions are used for this stage. various manufacturers. It is these types of primers that are suitable for processing most types of materials, be it brick, concrete, cement, drywall.
It is better to primer from the upper left corner, gradually moving to the lower right. Proper and high-quality priming of the surface will help ensure a more reliable adhesion to the coating, as well as remove dust residues if necessary. When applying the primer, you can use any convenient tool: a roller, a brush, even a cloth.
After so careful preparation you can safely apply paint without fear of detachments, bumps and other unpleasant defects. Application is best done in two stages: first, apply a thin base color, and then fix it with another thin layer on top of the first. Dry the layers thoroughly between applications.
Subtleties of application
Applying paint, like any other stage of the staining process, has its own subtleties and rules.
So, regardless of the tool with which the staining will be done, you will additionally need a flat brush. With its help, it will be necessary to paint the least accessible places in the room: corners, joints with windows and doors, as well as very small decor details.
With the painting of corners and joints, the entire responsible painting process should begin.. Moreover, the upper corner furthest from the doorway is decorated first. At this stage, there is nothing difficult: you need to take a flat brush, dip it halfway into the paint (it is more convenient if the paint from the general container is poured into a separate paint container), wring it out and start painting with light movements.
Along the entire perimeter, it is necessary to lay a strip of paint 30-40 centimeters wide. Such preparatory work will help to more evenly apply the coating with a roller, spray gun or airbrush in the future.
The main staining will be carried out in three stages: Stage 1 - 1 layer. There are some nuances here: each of the three layers should have its own coloring direction - this will help to avoid unpainted places, bumps, spots, too thin coating.
So, it is correct to apply mixtures in layers, focusing on the location of the window: 1 layer should follow in parallel sunbeams, 2nd layer will be applied perpendicular to the first, but it is necessary to complete the work with a layer whose direction will move exactly towards the window.
Painting is most conveniently done using a simple roller.. This, of course, is not as fast and smooth as when using an airbrush, but this method is the most budgetary. In addition, the roller can be easily bought at any store, and after finishing repair work just throw it away without littering the house with unnecessary items.
Between the application of layers, it is important to leave the necessary amount of time for the complete drying of the layer. Only after complete drying of one of them, you can start applying the second and third.
Applying paint to a wet layer is fraught with peeling and spreading of the material.
For information on how to properly paint a wall with water-based paint, see the following video.
How long does it dry?
Water-based dyes are considered the fastest drying among other coloring emulsions, however, the time for complete drying may vary depending on the type of paint, the material to which it will be applied, and even the manufacturer.
In order to determine the drying time of one or another option, it is necessary to study the annotation to the product. It is there that the manufacturer places more accurate information about the drying time of the dye. This indicator can vary from 2 hours to a day.
What happens to the paint during the drying process and why does this process happen so quickly? This pattern is possible due to the special composition of the mixture. So, any water emulsion contains water and a special binder. The applied paint, under the influence of oxygen, gives up all the water, which simply evaporates from the surface, leaving only the binder, which remains on the surface in the form of a colored film.
IN modern construction there are many new materials for interior decoration. And yet, painting the walls in the apartment is not inferior to its position. The use of water-based paint allows you to choose for the room perfect color and even texture. Various ways application, as well as textured rollers will help to display incomparable design variations. The main thing is to adhere to the basic rules and technology that requires painting walls with water-based paint.
That is already a separate topic and has whole line its features and nuances of performance. We will assume that the walls are already ready, and represent either flat surface with, or lined with one of the materials that is designed for further painting, for example, wallpaper, ceramic tiles, cork boards, etc.
Preparatory work
The entire surface to be painted is released. A space of at least 1.5 meters near it is also cleared. It is best to glue the strip on the ceiling and on adjacent walls at the junction with the surface to be painted and cover the floor. In this case, it is desirable to close the floor a whole meter from the wall.
The first layer to be applied will be the primer. It is necessary to ensure reliable adhesion of the paint and the surface. In addition, the absorbency of the entire surface is leveled, and due to this, the paint lays down more evenly without staining. The primer must dry sufficiently to form protective film. It's about 4-6 hours. You can check the drying time by checking the instructions for using the primer, as well as by touch.
Paint preparation
Water-based paint is sold quite thick in consistency. To obtain a uniform matte finish over the entire wall, dilute it with water and mix thoroughly.
for mixing better fit low speed drill with a special mixer attachment. If it is supposed to depict textured drawings based on water-based paints on the walls, naturally, you can not dilute the paint with water and use it in a thick form.
Paint preparation can be done in advance before work, but it should be re-mixed immediately before painting the walls with your own hands. Once the desired consistency is reached, the desired color can be given to the paint. For this, various colors are used, by combining which and adding certain portions to the paint, you can choose the desired shade. It is best to entrust this to the masters. Most water-based paint shops have a special machine for computerized paint selection and production. The main thing is that the automatic selection takes into account that the color will change during the drying process of the paint. Moreover, it is especially important to prepare a sufficient amount of paint with one shade for painting walls in one room, otherwise it will not work to get an identical shade manually. In extreme cases, enough paint is diluted to paint an entire wall, then the difference in shade on other walls can be attributed to lighting or to give a special effect. However, these are already too high decorative materials.
Paint application
Of the tools, wall painting technology involves the use of the following: rollers, brushes, sponges. Select the appropriate one to create the desired effect. You can evenly distribute the paint using a roller. The brush is best for painting small areas and the edges of the walls at the joints with other surfaces. You can decorate the wall with a sponge using a thick paint solution and creating a slight texture. The use of rollers with different pile lengths and stiffness also makes it possible to achieve different ink distribution effects. The best option is a roller with a soft pile of medium length.
- The paint is poured in a small portion into a special tray for rollers. You can get one at any hardware store and they are cheap. The perimeter of the wall is traversed with a brush so as not to risk staining adjacent surfaces with a roller.
- Further, in order to make it easier to apply paint with a roller, you should initially drag it out in it. It is best to use a sheet of thick paper or a board. It is enough to roll the roller until the pile is completely saturated with paint from all sides. After that, the painting of the wall begins.
- You can start from any position. Best on top. So streaks and drops, which will certainly jump off the roller, will not spoil the already painted places and will subsequently be rolled out by the tool.
How many coats of paint will be required?
In order for the covered finishing putty the wall the paint was evenly distributed and the color of the entire wall was correct, it is necessary that the walls of the room be painted at least twice, and preferably three.
This is due not so much to the thickness of the paint layer, but to the fact that the next layer will not be absorbed into the putty, even covered with primer, but will complement the first layer of paint. So you can grind the optimal amount of paint in each layer with high quality and get a normal result at a lower cost. Master painters know that even using a large amount of paint in the first layer will not lead to a normal result, unless smudges appear, which are then difficult to get rid of.
Subsequent layers of paint are applied after partial drying of the previous one, and best of all, complete. All the time allotted for drying the helmet, the room must be isolated from drafts. Also, contamination of previous layers of paint should not be allowed.
Different ways to paint walls
textured surfaces
Often, when painting textured types of cladding with water-based paint, such as, the base color of the base is applied first. In this case, a roller with medium, stiffer bristles is used to fill all the recesses, or a spray gun (spray gun). After that, using a bald roller or sponge, the protruding parts of the surface texture are carefully covered with paint of a different shade. This gives volume and the necessary visual effects.
Adding texture with paint
Also, the texture can be given with the paint itself. To do this, do not dilute it with water and leave it thick. IN simple version when applied with a roller, an uneven, rough surface is obtained, dotted with pimples. The more liquid paint you choose, the more blurry the picture will turn out. In addition, rollers are used textured surface or with scraps of material, like leather, with which you can combine colors and get a variety of ornaments. It is only worth considering that upon receipt texture staining material consumption increases significantly.
In addition to texture forming rollers, plain walls in your interior can perfectly diversify appliqué rollers..
We paint the kitchen
To paint the walls in the kitchen, it is very important to choose the right paint that would not wear out much in conditions of constant cooking. To improve the properties of the paint, it is better to open it with an additional special varnish, also water-based. Naturally, it is desirable not to paint the entire kitchen, because it is better to lay tiles near the working surface of the stove with a sink.
Painting the walls in the bathroom
The walls in the bathroom can be painted with water-based paint only if there is sufficient forced ventilation, because few paints can withstand an environment of high humidity without consequences. During the painting process and during the drying period, the bathroom must be closed from drafts and not filled with steam or moisture.
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 time-consuming of all the 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 applying leave in urgently room is not needed. The composition can be given different color. For this, special water-based colors are used. Subject to the recommendations, the staining process does not cause many problems. One of undoubted advantages compositions, consumers believe that the tools can be easily cleaned after application.
Possible difficulties
Whitewashing ceilings with water-based paint should be carried out 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, parallel to the source of penetration 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. Besides, in last case more likely to form streaks and glare. 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 experienced craftsmen note, the old coating layer is 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 device
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 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.
Traditionally holds its position in the design of pleasing to the eye and cozy interior water-based wall paint in the house, easy to work with and harmless to people's health. whitewashed ceiling will convey its ability to appear taller and fill with a sense of space even small room modern species floors painted with water-based paints different shades. The soft diffusion of light from the matte surface blends beautifully into almost any designer style. Skillful use of the properties of this paint and the technology of work always gives an excellent result.
Why take a water emulsion
In an apartment, office, technological room, painting walls with water-based paint with your own hands is often the best option for many reasons.
The composition, prepared on the basis of a water emulsion, does not fill the room with unpleasant fumes during painting work.
Matte soft texture is in demand in the design of children's rooms, high-tech and minimalist styles.
The technology of painting walls with water-based paint makes it easy to change the color saturation and create individual drawings and patterns without the use of dissimilar materials. An example of changing the tones of one color is visible in the photo:
Often this method of creating contrasting transitions of tones is used if the wall being decorated has some irreparable irregularities.
The high coefficient of moisture permeability of water-based paint allows it to be used for covering walls in a room with a high humidity index, with proper surface preparation.
WITH minimum cost forces and money with these compositions, you can simply whitewash the ceilings and walls of technological and utility rooms.
Differences in composition
Efforts to prepare and implement a creative idea are not in vain if you paint the walls with different water-based paints that match in their technical specifications with operating conditions.
Pay attention and bring together to your own work plans you need 1 coat drying time, expiration date, viscosity, conditions proper storage, the allowable base temperature at which walls can be painted.
The base indicator, which depends on the composition and is important for calculating the repair estimate, is the different consumption of material per 1 m², shown in the table:
The manufacturer's instructions also indicate on which surface to be painted this composition can be applied. As a base, both prepared plaster and finish coatings from various materials.
It is necessary to take into account not only the ability of the ink film to stay on the base, but also the resistance of the painted material to water. The aqueous solution does not need to be applied to paper wallpaper- they will warp and exfoliate. There are other roll coatings suitable for such an operation. An example of coloring non-woven wallpaper is visible in the photo.
The next step in learning the technology of how to properly paint the walls in your home will be to get acquainted directly with the differences in the recipe 2 large groups water-based compositions:
- The most popular paints are aqueous emulsions, which are made with the addition of acrylic resins. They give the resulting film high elasticity and mechanical strength. The cost of such brands is quite high, therefore, with a limited repair budget, they acquire cheaper varieties with acrylic components - vinyl acrylic or styrene-acrylic paint. The introduction of latex into the composition of the paint gives the surface (after it is painted) water-repellent protective properties. The film is resistant to abrasion and can withstand about 1000 wet cleaning cycles.
- Water-dispersion paints differ somewhat in their components compared to water-based emulsions. In them, the main components are polyacrylates, styrene copolymers and polyvinyl acetates. They do not dissolve in water, and after applying a layer of paint to the surface to be treated, they polymerize, forming a thin and durable coloring film. Requirements for compositions of this type are established by GOST 28196-89. “Water-dispersion paints. Specifications". This standard applies to "water-dispersion paints, which are suspensions of pigments and fillers in aqueous dispersions of synthetic polymers with the addition of various auxiliary substances (emulsifier, stabilizer, etc.)".
Both of these paint compositions include white (titanium dioxide, zinc oxide). IN inexpensive option chalk occupies a large mass fraction.
A simple technology for changing the color of the mixture allows you to choose for painting walls with water-based paint as a set of different already colored compositions, as well as one white mixture with a set of tinting pigments.
Paint preparation
Painting in white or prefabricated color requires only thorough mixing until a uniform consistency of the contents of the can is obtained before painting the walls with water-based paint.
Depending on the quantity, this is done manually with a convenient wooden / plastic bar, or with a drill with a nozzle, a construction mixer. It is not recommended to use non-anodized steel (ferrous metal) in work. When kneading the solution, metal grains can get into it, which subsequently, after contact with water, will appear as rusty spots.
In some cases, ready-to-use paint is additionally diluted with water before starting work:
- for the first layer with multi-layer painting of a wall or ceiling;
- the old mass, which has thickened after long-term storage, must be diluted, otherwise stripes and lines of different density are formed when applied with a roller;
- if the total expense includes the remnants of material from a previous repair.
To properly dilute the water emulsion, take an amount of water that does not exceed 10% of the total volume of thickened paint. Water is poured in in small portions, gradually, with constant stirring with paint in a large container.
To obtain a homogeneous consistency, a construction mixer or a drill with a special nozzle is used. When the uniformity of the composition is achieved, you can start painting the walls and ceiling.
To create your own shade and design a combined color coating on the same basis, add the required amount of pigment to the paint and knead until the desired saturation is obtained.
Another way is to dilute (blur) the saturated factory color with white filler. If the experience in this matter is still small, you can use special tables designed for designers:
Combine different colors and shades can be made from white water-based paint or composition of any other color by mixing the palette. For confident work, you need to remember a few basic rules for tinting with your own hands:
- you need to choose what color paint will be the main one and add other pigments to it;
- the final saturation shade of the paint appears after the final stirring to a homogeneous state; there is no need to rush to add the next portion of the dye;
- when mixing the mixture with a mixer, it is necessary to wait until the air bubbles completely exit and the foam disappears from the surface;
- the preparation of a single-color paint is carried out immediately in full before painting the walls with a roller on the entire planned surface area; it will no longer be possible to accurately repeat the shade obtained earlier;
- it should be remembered that when the paint dries, the color saturation changes, if you need accuracy in obtaining a certain shade, then it is first advisable to make test strokes on a secondary section of the wall.
Independent mixing of tinted paints makes it possible to obtain in practice any desired shade. Room design creative personality can be a riot of colors, then you should use one large container with a white base and a set of bubbles with different pigments, as in the photo.
Another technique for applying different shades is used when painting walls with water-based paint is done in a room where the lighting of different areas is not the same. On slopes, in niches, doorways, arched vaults, the plane of walls with windows (daylight does not directly enter), you can choose a lighter tone for painting.
With confidence, you can get the desired result by using only proven high-quality materials from well-known manufacturers.
The subtleties of the work
A good result is obtained if all preparatory work, knowledge of techniques, how to properly paint with various tools, following the manufacturer's recommendations.
You should prepare a convenient high-quality tool for work (brushes for corners, a roller for spacious planes, a paint tray, face and hand protection equipment). Additionally, they take a plastic film (cover the working area), masking tape to denote clear boundaries painting, a tool for preparing the base (cleaning, puttying).
cleaning
A stable even layer will be obtained if the wall is well prepared - cleaned and leveled before painting. Whitewash not washed off the ceiling, an attempt to simply cover the old paint with a fresh layer, leads to a loss of appearance, a quick peeling and warping of the new coating. Even if the previous finish was made with water-based compositions, they must be carefully cleaned (photo):
Old paint may come off appearance but still firmly stick to the walls. Specialists have developed techniques specifically for such cases. practical advice on surface preparation, how to quickly remove old water-based paint from the wall, is presented in the following video:
alignment
Before painting the walls with water-based paint, defects are repaired and the surface is leveled. After applying such a topcoat, uncorrected flaws will appear in all their glory.
Depending on the purpose of the room, these works are most often carried out with gypsum or acrylic putty, obtaining an almost perfect plane. Removing corners, sealing cracks and small shells, straightening individual sections of the walls are shown in this photo:
After the finishing putty has dried, it is cleaned with a grater over the entire surface until the same roughness is obtained for painting.
Use of special equipment
The need to paint large areas in short time raises the question of how to paint the walls with water-based paint without streaks in one color scheme.
For this purpose, created painting types equipment that does not require long-term special training. The only point is that it is not advisable to purchase them for the production of one-time works, therefore, they invite professionals or rent them.
Convenient work on applying paint on a large high ceiling area is shown in the photo:
Compressor spraying of water-based paint allows you to evenly apply it in layers without changing shades. The installation of special nozzles and nozzles makes it possible to make graphic images, changing the thickness and density of the ejected jet.
