No matter how fashionable the repair may be, the ability to update the interior in a matter of hours attracts many. And the first thing that the owners of such apartments recall is about wallpapers that can be repainted several times. Let's decide which paint for wallpaper is suitable for each type of wallpaper and how to choose it correctly?

Types of paints for wallpaper

What to choose paint for wallpaper

When painting new plaster, new small plaster cracks may appear. If this happens, you should fill them with a suitable dressing after the first painting, and then finely grind them before applying the next coat of paint. White, powdery and fluffy surfaces are sometimes created on the surface. After removing it, you must remove it dry so that it no longer appears.

If the area has been painted in the past, some peeling may occur. Before painting, remove all falling and exfoliating colors. If the previous layer shines under a new layer of color, this is usually caused by uneven coloring or excessive sanding. In this case you should apply a new color layer.

Before we begin to understand the question of which paint to choose for wallpaper, let's first recall what paints are used to paint the interior walls of rooms? These are water-dispersion paints (the latter are also called latex). Both the first and second types of paints have excellent characteristics, with the only difference being that water-based paints are washed off by water, and water-dispersed paints are not.

If the surface is too wet to be painted, you must leave it to dry before painting. If mold is on the surface, the surface must be treated with a sterilization solution and the mold removed. Holes may occur as a result of the movement of the plates. In this case, you must apply the gypsum, allow it to dry, and then fill the internal filler.

The remaining powder may remain on the surface of the plaster. Before you paint it, you must remove it with a dry rag or cloth. Do not remove it with sandpaper. Porosity affects the absorption of paint. If the surface is porous, you should dilute the first coat or use a suitable base coat.

Wallpaper painted with water-dispersion paint has a high resistance to moisture; by its characteristics, such a wall covering can be equated to washable wallpaper. The characteristics of water-based dispersion paints are largely dependent on binding polymers. For example, PVA-based paints have low moisture resistance, therefore they are used mainly in dry rooms. Paints based on acrylic resins have increased water resistance and wear resistance. Acrylic paints are not afraid of not only moisture, but also ultraviolet radiation (the surface covered with acrylic paint does not fade), in addition, they quickly dry out and allow the walls to "breathe". Agree, is this the best paint for wallpaper?

This phenomenon may occur due to the lack of an adhesive surface or poor preparation before painting. Remove the blister by carefully cutting and applying glue to the back of the paper and to the wall. Allow the glue to soak and then taper the paper. This may be due to insufficient adhesion of the old wallpaper, which you must return to the new paint.

Soft vinyl glitter or blown wine vinyl silk can sometimes cause stickiness. You will not be able to use a vinyl mat as an initial coating. When drawing blown or embossed wallpapers, the paint may sometimes appear stained or the relief is incorrectly filled. This can be avoided by using appropriate rollers that match the terrain.

Water-dispersion paints, as well as water-based paints, are environmentally friendly, they do not contain volatile diluents, therefore, such coloring compounds are allowed to be used even in children's rooms.

Unfortunately, simple operations can be complicated by poor-quality glue, improper surface preparation or improper surface treatment, since fiberglass wallpaper belongs to the so-called wallpaper group. Paint. Traditional paper wallpaper adhesives - those that have been sold for decades in cardboard packaging - are a mixture of cellulosic compounds with additives to prevent mold growth. Their preparation was to dissolve in water, with the usual advice of manufacturers talking about the preparation of a 10% solution of glue.

But the list of advantages of these paints does not end there. Both water-based and water-based dispersion paints are quite economical and easy to use, they have virtually no smell. You can paint the walls with a brush, roller or using a spray, here anyone like it more.

Coloring paint for wallpaper

Pure glue is poured into water for continuous mixing until all the pieces have dissolved. This prepared glue can be stored for 4 days. Fiberglass adhesives are water-soluble liquid suspensions consisting of a binder, which is most often a dispersion of polyvinyl acetate, fillers, sometimes pigments and excipients. The latter are substances that prevent glue formation, ventilation, stabilization, etc. such glue is usually ready for use after manual or mechanical mixing.

Wallpaper paint colors

Now let's see what are the colors of wallpaper paint? Water-based dispersion paint is mainly available in white, and water-based dispersion paint can have a different color. You ask, why do we need paint for white wallpaper, if we want to give the walls a color tint? We answer - water-dispersion and water-based paints need to be tinted, then they will take the color that is needed. Even if you need to give the wallpaper a color of gold, silver or bronze - this task is feasible!

Ease of use is a commercial form that does not require any operations other than mixing, as required by a powder adhesive. Like any product on the construction market, wallpaper adhesives must meet certain quality standards so that they can be sold. Certified adhesives are then issued with a certificate that gives the manufacturer the right to issue a declaration of conformity.

The first parameter, which is taken into account when gluing wallpapers, is the possibility of application. As a rule, this type of glue is applied by brush or roller and therefore must be designed so that they do not withstand during application, but also do not splash and drip from vertical surfaces. Fast movements are, for example, mixing glue, coloring and slow glue behavior during storage, leaving a wall during application, where gravitational effects cause bleeding. A requirement was established that determines the viscosity of adhesives with high quality parameters.

There are two ways to make color paint. The first way is on your own at home. To do this, a pigment of a suitable color is bought and by mixing it with paint the desired shade is achieved. It would seem that everything is simple: take and mix the paint until the desired color is obtained. But there are drawbacks.

Firstly, the color of the paint in the bucket will probably differ from the color of the walls after drying, and how it turns out is hard to guess. Secondly, when the first bucket finishes, you will have to mix the colors in the second, but can you give the paint the same shade with an accuracy of 100%?

The gluing time of fiberglass glue should be set enough to cover the wall covering for wallpaper, wallpaper bonding, smooth and proper alignment. A good glue should dry for at least 1 hour, but not more than 3 hours. These times are lab tests that are strictly standardized. Actual conditions may differ from normalized conditions, so the requirement was set quite sharply, setting the lower limit of the minimum drying time. If the painting of the wallpaper takes place in a room with a higher temperature, the glue will dry faster.

Paint for painting wallpaper

Surely not. Therefore, it is better to resort to the second method of tinting.

The second way is computer tinting. With the help of tinting machines, the necessary amount of paint will be tinted for you to paint the wallpaper in any color, and all the containers will have the same shade. The advantage of this method of tinting is also that if the purchased paint is not enough to paint the room, then it will not be difficult to tint the next bucket in the desired shade, and the color will match 100%.

Quick-drying adhesives are impractical because you won’t be able to glue wallpapers or smooth them because the glue is already dry. The application of adhesive coating should be done along the width of the wallpaper for wallpaper, which is usually equal to the width of the wallpaper for wallpaper. A feature that determines the adhesion of the adhesion of wallpaper attached to the substrate. If we paste drywall, then after 3 days of gluing, the wallpaper that needs to be cleaned should come with a cardboard cover plate. The study also shows the quality of wallpaper that can weaken the weave.

The test is carried out on a sample of drying glue in the laboratory and is subjected to hygrothermal changes, as follows. Tensile strength after steam test. . After removal of the sample, a tensile strength test is performed. The glue meets the requirements when the strength is not worse than before being placed in the chamber.

Choose a paint for the wallpaper

We have already talked about the main types of paints, and now we will go directly to the choice of paint, depending on the type of wallpaper.

Paint for non-woven wallpaper is any water-based. An unusual way to change the color can be considered their staining from the inside. For this, acrylic paint is used, which is applied to the wallpaper sheet before gluing. The result is a uniform background against which the wallpaper structure beaten off at the factory stands out.

This test shows the suitability of the adhesive for use in the so-called Wet, for example, kitchens, bathrooms, saunas. Tear resistance after thermal aging. . The sample, as described above, was placed for 4 days at 50 ° C, then removed, cooled to ambient temperature and subjected to a tensile strength test. The test result is required, as indicated above, and the test itself indicates changes that occur over time, since each increase in the temperature of the exposure of the sample accelerates changes in the sample.

The ubiquitous myth about this study says that you can paint it on the walls. Of course, this study is mainly for internal emulsion paints, but it does not say whether it is possible to clean the wall, rinse, etc. it is a sign of resistance to coating, which is checked by cleaning a standardized washable liquid brush with a 1% solution of Gray Soap. Glue for gluing is also checked for scratch resistance, but not to say whether it can be washed, but to determine the mechanical strength.

Paint for vinyl wallpaper is taken acrylic on a latex basis, but if, then you can take a water-based emulsion. As in the case of non-woven, vinyl wallpapers can be painted both on the inside and the outside.

For paper wallpapers, any paints are suitable, you can use both water-based and acrylic. The principle of painting does not differ from the technology of painting other wallpapers: an even layer of paint is applied on a dry and even surface with a roller or spray.

The adhesive coating must be well permeable to water vapor, so that the adhesive cannot be an obstacle to transportation. Depending on what the basis for the wallpaper is, the procedure is different. Drywall base must be free of dust and dust. Cement and cement-lime substrates must be primed to the desired seasoning season, preferably flaxseed, with gasoline on varnishes. This soaking allows you to bind free aggregates and incomparably surpass the primers of a water-based primer.

The surface of the drywall is not primed, but if possible, the plaster with gypsum plaster should be primed with a good primer. After a water-based primer, wallpaper can be done after 2-4 hours and after 3 days. If the substrate, especially cement plaster, cannot be welded for any reason, for example, the smell of varnish and gasoline, irritates the person, and then the application of glue should be applied to a damp substrate. Soak water in a bucket of clean tap water. This will help extend the drying time of the glue.

Paint for paper wallpaper

If you are looking for paint for, then know that in most cases they can not be painted, their color is achieved due to the color components included in the mixture. When it comes to paint for liquid wallpaper, then, most likely, they do not talk about painting the wallpaper itself, but about painting the walls, on which a decorative mixture will subsequently be applied. The layer of paint that is applied to the base prevents all kinds of stains, for example, rusty, from appearing through the wallpaper. For the most part, oil paint or nitro enamel is used for this purpose, or water-based dispersion paint with the addition of quartz sand (Ceresit ST-16 primer is a good example).

Glue and wallpaper bonding

Hydrophilic dispersion products are always preferred for wetting the substrate. This rule does not apply to gypsum and putty surfaces and plasterboard surfaces. Glue is best applied with a brush to the bench. You can also have a medium length roller roller. The glue is applied to a previously prepared wall with a strip width corresponding to the width of the roll. Glue should be avoided by covering the wall and overlapping so that the adhesive layer is between 0, 5 and 1, 5 mm, depending on the wallpaper pattern.

Wallpaper for painting has changed the approach to the problem of constant design of the room. With their help, annoying shades can be easily changed. The main thing is to correctly approach the painting process itself. It should be noted that painting wallpaper is a serious matter. It would seem that here are the wallpapers that need to be painted (see photo below), here is the paint for them. But this is not ordinary wallpaper, there are several types of them, so the painting process itself will depend a little on what material is chosen for wall decoration.

Apply the wallpaper to the ceiling, stroking a strip of wallpaper with a plastic spatula, pressing evenly to distribute the adhesive under both. The porous texture of the wallpaper allows him to drown almost in glue, although he cannot rely on excessive bonding. The glue should be enough on the wall so that it does not shrink between the fibers of the wallpaper. The bonding of the waist also begins, of course, with the message, i.e. the continuity of the wallpaper pattern. The best way to start gluing is from the corner and move towards windows and doors.

During gluing, the drying time mentioned above is important, which should allow all operations and give time for possible corrections. If after gluing the wallpaper we observe a flow of wallpaper, this means that the glue is too thin, i.e. It has low viscosity and cannot hold wallpaper on the wall. Often the reason is to dilute the adhesive before use, but it happens that low-quality adhesives immediately after purchase.

Types of wallpaper for painting

There are three types of wallpaper for painting. All of them have high moisture resistance, they have a relief coating, the absence of a color pattern, plus they hold paint well. Moreover, all three categories differ from each other in the raw material from which they are made. What unites them is that they can be painted and repainted several times. Almost all wallpapers of this type go on sale unpainted. Some manufacturers offer pastel colors: beige, gray, pink or cream, as shown in the photo above. But they are easily painted over.

Sticky wallpapers are not seasoned with any means, but immediately begin to draw. Two types of paints should be used for painting. These paints are typical emulsion paints. We respect the purchase of so-called paint. Due to the national nomenclature of latex, such paints do not exist, and manufacturers who produce and call in this way do not know that they are very low-quality products, despite the high content of the binder. These types of paints are water vapor insulation, so they perfectly seal the room or the whole apartment, which leads to the formation of mushrooms and mold on the walls.

Paint for painting wallpaper

An important question that excites consumers is what paint to paint the wallpaper. It is clear that any paint material is not suitable here. As with the wallpaper itself, there are three varieties.

Water based paint.
Water dispersion.
Based on latex.

The first two positions are water-based paints. It’s just that the former has a smaller filler fraction, the latter has a larger one. That is, in the first type of paints, the filler particles are smaller than the second. In this case, the emulsion can be easily removed with a sponge and a small amount of water. Dispersion paints on the treated surface form a dense, durable film that cannot be removed with water. Only a solvent can be used for this. In addition, they dry quickly, because they include polymer - acrylic.

Latex paint is the most expensive option from this category of paint products. But applied to the wallpaper, it creates the conditions for their long-term operation. They have the highest water-repellent characteristic, it does not fade under the influence of sunlight, has excellent strength. Typically, this paint is used in rooms with high air pollution, for example, in kitchens. In addition, wallpapers coated with latex paint are easy to wash, and the paint itself does not leave the wallpaper surface.

Attention! If latex paint is used to decorate paper wallpaper for painting, then their surface becomes glossy. But it is important to pay attention to the fact that each such paint has its own degree of gloss, which is indicated on the package.

And a few more tips.

Non-woven wallpaper for painting is best painted with acrylic paint or latex-based.
In humid rooms, painting the wallpaper with PVA-based paint is not worth it.
Before buying a paintwork material, it is necessary to calculate its consumption so as not to buy excess. The packaging usually indicates the consumption per square meter. It is multiplied by the area of the walls on which the wallpaper will be glued. This will be an expense. But experts recommend adding another 10% to it.

There are several points regarding paint consumption. Typically, for painting wallpaper in one layer, its consumption is 150-180 g / m². If the application is made in two layers, then the expense indicator increases to 250 g / m². It should be noted that painting wallpaper with a rough surface is more economical, especially with regard to cullet.

Painting technology

Before you start painting already pasted wallpapers, you need to prepare several tools and devices. These are several rollers: one with an average pile length (photo below), the second round, with which you can easily paint over the corners of the room. A brush to help paint over the edges of pasted wallpapers. A bath where paint will be poured.

Now we are preparing the paint itself. This is a ready-to-use material, but the first applied layer will play the role of a primer. Therefore, part of the paint must be diluted with water in proportion: one part of water, ten parts of the material itself.

First of all, the edges of the wallpaper and the corners of the room are painted with a brush or a round roller. To do this, a wide spatula is installed on the upper edge of the laid finish. It will create a barrier that closes the ceiling surface so that the paint does not get on it. Paint should be 8-10 cm down from the spatula.

Then, using a conventional roller, diluted paint is applied to the wallpaper. Lay the material vertically, as in the photo above, no side or horizontal stripes. After the walls are completely coated with a primer, it is necessary to allow time for them to dry. This is usually given at least one hour. Then, in exactly the same order, the main coating is made with undiluted paint.

Choose the right shade

Currently, manufacturers offer both pure white paint for painting wallpapers, and with a fairly wide shade model range. But, as practice shows, many consumers choose the white option, then to independently adjust it to the desired shade, doing it yourself, just adding color (pigment).

The easiest option is to pour color in the paint and mix the mixture thoroughly, as shown in the photo. But this simple option for obtaining the necessary shade has a negative side. Firstly, after drying the paint on the wallpaper may not get the shade that you expected. By the way, this happens quite often. Secondly, this method is better to use, so to speak, in total. That is, all banks are merged into one large capacity, into which pigment is then added. If mixing is done separately with each jar, then the probability of a miss of color in each case with other banks is very high.

Therefore, it is recommended to use another more advanced option. To do this, you will have to use special computer equipment for mixing paints. It is important to remember the code of paint and color scheme. Next, the computer itself will determine in what quantity, what kind of paint and color should be mixed. Such installations are usually used in colorful automotive workshops.

Room Wallpaper Shades

Sometimes it is difficult for an ordinary person to choose one or another shade of paint for wallpaper. Therefore, here are some recommendations from designers.

Light pastel colors visually expand the space of the room. The same can be said about glossy surfaces. Therefore, the color of such paints are usually used in small spaces.
Dark blue or black color makes the room dull and gloomy. Therefore in living rooms it is better to refuse them. Although there are many creative designers who often use such paints, but they are applied to areas, and not to all walls.
Bright tones (red, orange) are often used to focus on a specific area. True, a person quickly gets tired of such paints.
Warm colors (pink, yellow) create comfort in the house.
Brown, blue (photo above), green - these are natural colors that will fit in any room.

In general, wallpaper for painting make it possible to repeatedly change their colors. Therefore, you can safely experiment. For example, paint the bedroom like this, as shown in the photo above, in red. Let's face it, a bold decision. But if such an interior gets bored, and it gets bored quickly, then you can easily repaint the walls into another more calm tone. True, it is necessary to paint over the red color in two layers.

Conclusion

But what is most interesting when it comes to staining. Say what you like, and this is quite a serious process with the cost of purchasing paints and varnishes. It may therefore be worth not to rush into painting. It may be worth buying wallpaper of the required color, since the construction materials market today allows it. This is a good money saving. In addition, there is always the possibility to change the coloring of the laid wallpaper, simply by repainting them in another selected color.
