Is it possible to glue wallpaper over old paint? How to glue wallpaper onto paint: determining the type of coating, working with water-based and oil-based paints. Determining the type of coating

The most popular finishing material for walls is wallpaper. They have, compared to others, more low price. Working with them is easy and simple. And of course, they benefit from a wide selection of colors, designs and the material from which they are made.

Wallpaper material is not always purchased in order to fulfill major renovation with new design. Very often, consumers just want to freshen up a room without spending a lot of effort. In many apartments, especially in kitchens, the walls were previously covered with paint. And now the question arises: is it possible to put wallpaper on it? Of course, according to the technology, they should be glued to a base lined with plaster or to drywall. But as practice shows, gluing wallpaper onto a painted surface is quite successful. The only challenge is how to make them last longer.

What to pay attention to

To get a positive result when gluing wallpaper on painted walls, you should first consider several points:

Features of different types of paint

Treatment of surfaces with different types of paint differs in its technology, and, consequently, in the result of the work. Therefore, it is very important to determine which one was applied to the wall earlier. It happens:

A prerequisite for preparing the surface is determining the type of paint. To do this, we begin to clear the walls of it. If it is removed in small layers, then paint was applied to oil based. Acrylic is very difficult to remove, so during this process only small shavings will form under the spatula. After determination, we proceed to preparing the surface for pasting.

Wall with acrylic paint

A plane with acrylic paint prepared as follows. A thorough primer is carried out with a solution, which is a solvent with the addition of a primer. This mixture, with the help of a solvent, forms small depressions on the surface. This will help improve the adhesion of the wallpaper material.

After the applied layer has dried well, the process is repeated. The second is applied only with a primer. The finishing layer is the application of well-diluted wallpaper glue to the walls.

Oil-based paint surface

Preparing bases with oil paint can be prepared in two ways:

Wallpaper and water-based paint

When deciding to wallpaper a wall with water-based paint applied to it, you should first perform several studies. First of all, you should check the strength of its coupling. To do this, apply it to the walls using paint brush plain water. If, after getting wet, the painted layer does not swell, then, in principle, wallpaper can be glued to such a plane.

Otherwise, it will have to be washed off. When deciding to apply wallpaper to a painted wall, we first carry out work to prepare it. Water-based paint attracts dust and grease particles. Therefore on initial stage You should wash the walls well with clean water. Then we examine the base on the unevenness. If there are any, then we putty them. And the final moment is priming the walls. There is no way to skip this process, even for the sake of saving money. Only through priming can the quality of wallpapering painted walls be ensured.

Wallpapering concrete walls

Since we're talking about wallpapering non-standard surfaces, let's figure out whether it's possible to wallpaper unplastered surfaces. concrete walls. After all, concrete surfaces have such a feature as the presence of potholes and tubercles.

You can try, but first we carry out certain preparations. First, let's treat the concrete walls with bricks to remove all possible bulges. Then we carefully polish sandpaper and clean the walls from the dusty layer. We prime the concrete and then cover it with wallpaper. But it’s still better to plaster it at least once to level the base.

After completing all preparatory work, you can begin the process of gluing the walls. To achieve a positive result, you should adhere to the following recommendations:

By following these simple rules, you can hang wallpaper and quickly update the design of your room.

Is it possible to glue photo wallpaper onto water-based paint? They will tell you in the following video:

Wallpaper remains one of the most popular finishing materials. To ensure good adhesive properties of the surface, it must be prepared before gluing the rolls. However, often the walls are covered with a layer of old paint, which is not always easy to remove. We will tell you how to glue wallpaper onto paint in this article.

Coverage type

In order to apply high-quality wallpaper, it is important to decide on the type of paint coating at the very beginning.

There are two most common types of paint:

1. Oily. It has a strong odor and has a good water-repellent effect. After setting, a protective layer, protecting the surface from negative impacts external environment.
2. Acrylic (water-based). Acrylic paints and varnishes are odorless, water-repellent and have good adhesion. After application, acrylic penetrates deeply into the surface structure.

To answer the question of whether it is possible to glue wallpaper over paint, you need to have an idea of ​​the hardness of the coating. All paint that can be easily removed must be removed, otherwise there is a risk that the painted layer will later fall off along with the wallpaper.

To check the strength of the paint, just poke around with a spatula in the old paintwork. Oil paint peels off in whole layers, but acrylic paint sticks much stronger and is removed in small pieces.

Instructions for performing work

Sometimes there are difficulties in determining the type of paint and varnish material, but there is a need to glue wallpaper onto the paint without priming the surface.

To complete the work you will need following materials and tools:

• wallpaper rolls;
• adhesive composition;
• foam roller;
• capacity;
• hot water;
• primer;
• scotch;
• putty knife;
• putty;
• sandpaper.

Preparatory work

The highest quality results can only be achieved by applying primer to paintwork. After treating the surface with a primer, apply a layer of putty to level out all unevenness.

Over many years, the old coating absorbs all kinds of unpleasant odors. This especially applies to the kitchen and to rooms where there is a lot of smoking. Walls in damp rooms are often affected by fungus or mold. It is not recommended to glue rolls onto such surfaces without preparation.

First of all, we treat the surface with a special agent (for example, an antiseptic composition). Before you apply wallpaper to paint, you can do the following:

1. We cover the wall with a roll of thermal insulation.
2. Glue a plastic mesh on top.
3. Apply a layer of plaster.
4. We install and fix the sheet of drywall.

Wallpapering

Regardless of the type of coating, when gluing wallpaper, it is recommended to adhere to the following general principles:

1. If there is a pattern on the sheets, then when gluing different rolls, the fragments of the images should fit together smoothly.
2. We purchase wallpaper with a small supply (usually 1 roll is enough).
3. Not every adhesive is suitable for some types of wallpaper. Before applying glue, carefully read the instructions from the manufacturer and follow its recommendations when performing the work.
4. The work will go easier and faster if you have an assistant.
5. We cut a strip from the roll and place it on the floor with the pattern down. Next, apply a layer of adhesive evenly over the wallpaper.

1. We lift the glue-treated strip by the corners and stick it on the wall. We glue wallpaper from the window and above. Carefully press the sheet to the surface. At the same time, we distribute the gluing efforts from the middle of the sheet to the edges and down. Using a cloth or roller, remove excess glue from the surface.
2. We initially seal the switches and sockets found on the wall, and then release them using neat slits.

Features of acrylic surfaces

Before gluing the wallpaper onto the paint, prepare the surface. To do this, apply a mixture of primer and solvent to the wall with the old paint layer. This composition will allow you to change the structure of the painted surface, forming small defects on it. Such depressions will improve the adhesive properties of the coating, so that the wallpaper will stick better to the wall.

When the wall is dry, we treat the surface again, but this time only with a primer. A layer of highly diluted adhesive can be applied. We start gluing the rolls only after the surface has completely dried.

Check out more detailed instructions for wallpapering with water-based paint.

Pasting on oil paint

Despite the fact that, as mentioned above, oil paint can chip off in layers, it is a very tenacious material. Besides oil coatings very smooth, which seriously impairs their adhesive qualities and complicates the gluing of rolls.

We glue wallpaper onto oil paint only after preparatory activities. There are two methods of gluing wallpaper onto surfaces treated with oil paint:

1. First, we treat the surface with coarse sandpaper, and then apply primer and PVA glue to the sanded coating in a 1:1 ratio.
2. Using a spatula, we make grooves in the paint layer: a 5 cm channel every 20 cm of the surface. Place putty into the resulting grooves flush with the painted coating. Thus, we obtain areas with good adhesion, which will facilitate high-quality wallpaper gluing. It is believed that gluing wallpaper on oil-based paint in this way is less effective than on a sanded surface. However, this method is applicable if for some reason it is difficult to sand the entire surface.

Note! In the case of oil paints, it is recommended to use twice as much wallpaper glue as PVA glue.

So, it’s quite possible to glue wallpaper onto a layer of old paint. However, it is impossible to do without preparatory measures, since otherwise it will not be possible to properly glue the wallpaper to the wall.

Determining the type of old finish

Finding out what paint was used to decorate the wall is not difficult. So, even if you don’t know what the previous owners or builders covered the surface with, it’s not a big deal.

• If you run your hand over the surface and a white mark remains on it, then you have chalk whitewash.
• Acrylic (water-based) paint is visually similar to lime whitewash. To understand what is in front of you, do a test: wet small area water. Lime whitewash will darken, but water-based paint will not.
• Water-based emulsion, like whitewash, can be washed away with water.
• A durable, smooth, shiny or glossy coating is enamel (PF or NC).

Oil paint, like enamel, also forms a durable, smooth layer. It is extremely difficult to distinguish them. If the repair was carried out not very long ago, then oil paint can retain an odor: if you chop off a piece with a spatula and rub it, you can hear a faint smell of drying oil. If we talk about gluing on a painted surface, then this difference is insignificant, since the technology of work will be the same.

Latex paint is also difficult to identify. It has a slightly different structure than a regular water-based emulsion, although it is a variety of it. But there is a way - if you walk over the surface with sandpaper, the oil paint and enamel will fall off in small flakes. The latex coating, like a simple water-based emulsion, will be smeared on sandpaper. Thus, if the coating is not washed off with water, but remains on the sandpaper, it is latex paint.

Is it always possible to glue wallpaper onto old flooring?

In some cases delete old paint necessary, since the wallpaper will either not stick or will subsequently come off the wall. There are four options when a complete cleanup is necessary:

1. chalk or lime whitewash was used for finishing;
2. the paint was applied a long time ago, it has lost its structure and is peeling;
3. plaster or putty is coming away from the wall in many places;
4. if the wallpaper is light and loose, and the old finish is darker.

In the first case, if chalk or lime holds well, has a uniform structure and a small layer, then you can take a chance and glue thin paper wallpaper. To do this, you need to first apply a primer to the wall. deep penetration, and after drying, glue the canvases. However, the reliability of such a coating will be questionable, so it is still better to remove the whitewash.

Chalk or lime can be removed using a special solution; it is commercially available in concentrated form. It is diluted before use hot water and applied to the surface. After this, when the whitewash layer swells, it can be easily removed with a spatula and the residue can be washed off with plain water. Oil and enamel paint can be removed using special solvents and construction hair dryer. If the plaster comes off, remove it only decorative covering not enough. In this case, you will have to remove the entire plaster layer and prepare the wall from scratch.

How to glue wallpaper over water-based paint?

It is not difficult to prepare a wall painted with water-based emulsion. Before gluing wallpaper on painted walls, you need to perform the following steps:

• clean and putty problem areas;
• degrease the surface using any household detergent;
• apply acrylic primer and wait for it to dry;
• use glue solution, which is suitable for the selected wallpaper.

For gluing onto water-based paint, paper or non-woven wallpaper is best suited. When they dry, more moisture is released into the air than into the wall. But canvases with a dense top, on the contrary, transfer moisture more into the wall, which can lead to the destruction of the paint layer, and the glued wallpaper will come off.

Preparing walls with latex paint

By latex paint Wallpaper can be hung if you first degrease the walls and prime them. Any Fairy type detergent is suitable for degreasing. But the primer must be chosen carefully. Adhesive concrete-contact primer is well suited for acrylic base. We have to wait completely dry primer and then start gluing.

How to hang wallpaper on oil paint and enamel?

The success of wallpapering over enamel and oil paint depends on the adhesive, primer and surface preparation. If you choose the right glue and primer, and the enamel layer has not lost its structure, the wallpaper will stick securely. To determine the condition of the old coating, you need to conduct a small experiment - attach a strip of ordinary tape. Once removed, this strip should remain clean. If there are pieces of enamel left on it, you will have to completely clean the surface. If the paint holds well, you need to do the following:

• sand the entire surface to make it rough;
• putty problem areas(cracks, depressions, potholes);
• clean from dust;
• treat with a mixture of deep penetration primer and solvent (ratio 1:1);
• add PVA to wallpaper glue (ratio 1:4). If glue is used for vinyl wallpaper, then there is no need to add PVA.

Instead of a ready-made primer, you can use your own prepared mixture. To do this, alabaster is mixed with water to form a thick kefir, and PVA is added to this mixture, approximately 1/3 of the resulting volume.

If you want to do good repair, which is designed to last for decades, it is better to prepare the wall “according to all the rules of art.” That is, remove the old paint and be sure that it will not cause unwanted surprises. If you prefer to frequently update the interior of your home, then, following the above recommendations, you can paste wallpaper on the old decorative covering.

The decision to carry out repairs does not come immediately.
but even then we try this process delay until the last moment, when the finish of all surfaces slowly begins to fade, and in some places even fall off. Therefore, in order to refresh your apartment or house, it is often enough to carry out repairs “on quick hand" And here a serious question arises: how to decorate the rooms in your house. Increasingly popular in this moment use wallpaper as the cheapest and most effective method finishing of ceilings and walls. But what to do if there is old paint left on the walls, applied a long time ago, and how to hang wallpaper over the paint. This is possible subject to certain mandatory conditions.

4. Pasting concrete walls

Determining the type of paint

To properly wallpaper, you need to first determine the type of paint that was used to paint the walls. There are several types of paints. Acrylic water-based paint does not have specific smell, has water-repellent properties, fits well on walls and is absorbed into them, being firmly fixed in the structure.

Oil paint has a certain smell, perfectly repels moisture and forms a “protective layer” on the surface after drying. To understand whether you can stick wallpaper onto paint and how to do it correctly, try removing some of the paint from the wall with a spatula: oil paint will fall off in pieces, while acrylic paint, on the contrary, holds tightly and is removed only in small parts.

Before painting

Old paint on the walls gives owners a lot of not very pleasant moments, such as bald spots and cracks that appear when the paint material partially peels off along with the plaster, and all sorts of unevenness from the sagging that remains from old random brush strokes, or just color oil paint, which is pretty boring. And if the walls of the kitchen are painted, then to these troubles it is worth adding the old rancid smell that has ingrained into them.

Wallpaper should not be glued to moldy or damp walls. It is absolutely not enough to treat these areas with an antifungal drug and simply dry them. It is recommended to eliminate the cause that causes mold and dampness. The most simple means It is considered to be attaching a piece of rolled heat insulation to the wall, and then sticking a plastic mesh on it, plastering it with a layer of dry mixture, or simply covering it with a sheet of drywall.

When choosing wallpaper, you should take into account that if there is a drawing or pattern on it, then the owners will have to join it in such a way as not to disrupt the integrity of the pattern. Always buy one more roll. Before gluing wallpaper onto paint, it is recommended to carefully read the instructions for making the adhesive and follow its instructions strictly. You cannot use glue that is not intended for the selected type of wallpaper, for example, bone glue.

It is customary to glue wallpaper starting from the window. It is better to carry out such work together: in this case, one person will glue the upper part, and the second will glue the lower part. Having cut a strip of the required length from the roll, you need to lay it with the wrong side up on the floor. Use a brush to apply the glue, spreading it evenly over the entire surface of the wallpaper, and then lift it off the floor, folding the ends of the strip together.

Paste wallpaper onto paint, drywall or old wallpaper from the top. The strip should be aligned with the ceiling and placed tightly against the wall. Using movements that resemble the shape of a Christmas tree, you should press the wallpaper tightly against the wall from the middle of the strip - to the edges and down. It is better to do this with a rag or roller. You can also use a rag to remove excess glue that has come out around the edges.

The next strip needs to be glued in the same way, but taking into account the wallpaper image. The strips should be placed end to end, but not overlapping. You need to go over the joints again with a rag to fix them well. Switches and sockets must be covered with wallpaper, and immediately cut with a construction knife or blade crosswise in two lines. Then the excess part should be carefully trimmed around the perimeter of the switch or socket.

Under window openings and above the door the wallpaper is glued after all the solid strips have been glued. Is it necessary to glue wallpaper on the walls where it will stand? furniture set? You should do so at your own discretion. If you plan to rearrange the furniture in the future, then, of course, it’s worth hanging wallpaper. It is strictly forbidden to use hot glue, because its consistency becomes liquid, which is the reason that the adhesive composition begins to protrude beyond the edges of the canvas, staining the front side of the wallpaper.

We glue wallpaper with water-based paint

To hang wallpaper on water-based paint, you must first prepare the walls, otherwise the canvas may quickly fall away from the surface. First of all, you need to neutralize old layer paint substance. To do this, it is customary to prepare a mixture of primer and solvent in a 1:1 ratio and apply this composition to the surface to be treated. The solvent included in the mixture partially corrodes the old coating, allowing the primer to penetrate the wall structure and provide a reliable connection to the new finish.

After this, the wall should dry, and only then can a layer of clean primer be applied on top. This method allows you to obtain a rough surface, which is necessary for good adhesion of the wallpaper to the surface. After drying, the wallpaper is directly applied to the paint. For these purposes it is necessary to prepare special composition, which consists of equal parts wallpaper glue and PVA. It should be applied to wallpaper and to a primed wall.

Wallpaper sticker with oil paint

Oil paint is a very tenacious substance that can stick to walls for years. But in in this case the whole difficulty lies in the fact that the layers of paint have very smooth surface, which prevents the wallpaper from achieving good adhesion to the wall. Based on this, when planning to stick wallpaper on oil paint, you also need to do preparatory work. There are two methods for preparing walls covered with oil paint.

The first of them is as follows. To obtain a surface suitable for pasting, you should treat the walls with coarse sandpaper and apply a mixture of primer and PVA glue in a 1 to 1 ratio to the sanded surface.

The second method is this. Using a spatula, it is customary to remove every twenty centimeters horizontal stripes a layer of paint that is 5 centimeters wide, and then apply putty to the treated areas to level them with the rest of the surface. These strips are designed to ensure good adhesion of the panel to the walls. This method of gluing wallpaper with oil paint is considered less effective, but it also has a right to exist.

There is no need to repeat how to glue wallpaper onto paint - the sequence of actions is similar. The only difference is the composition of the adhesive solution - when gluing wallpaper on oil-based paints, you should use 2 times more wallpaper glue than PVA glue. By following these steps you will receive good result. The wallpaper will hold tightly, delighting the owners with its appearance.

Wallpaper sticker on whitewash and enamel

You already understand that water-based paint can be washed off. warm water using a rag. But there are other finishing materials. For example, the situation is more complicated with whitewashing, because this material is not able to withstand any loads. If you plan to put wallpaper on whitewashed walls, remember that the whitewash will have to be removed completely. To do this, soak it a little with soapy water and then remove it with a spatula. Wash off any remaining residue with warm water using a sponge. You cannot leave even the slightest area that has been whitewashed.

It is very easy to check the opposite. It is enough to run your palm along the wall with your palm and analyze the result. If there is even a little chalk left on your hand, you will have to wash the wall again and remove the last traces of whitewash. Without doing this, you don’t have to take on wallpapering - all your efforts will be in vain. Eventually, the wallpaper will come off in the places where the paint remains, and bubbles will appear if moisture appears there.

Second preparation option whitewashed walls Before applying wallpaper, treat the surface twice with a primer, which has deep penetration, and dry each layer well. After this, you should prepare glue diluted with water. The water content should be 20%. It is customary to treat the walls with this composition, then you need to wait for the substance to dry completely and you can glue the wallpaper.

But if the surface was painted with enamel, then in this case it will be possible to glue the wallpaper directly to the walls. But you must first make sure how firmly the paint adheres to the wall. You need to remove the enamel in those places where the substance falls off on its own. Be sure to go over the entire surface with coarse sandpaper and remove dust from the wall. For greater strength, it is recommended to pre-glue the surface with a special impregnation for walls.

Pasting concrete walls

Since we are talking about how to glue wallpaper onto paint, and we are talking about non-standard surfaces, we should definitely mention an ordinary concrete wall, which can serve as a basis for wallpaper. Many developers are interested in how to glue wallpaper to concrete. Of course, it seems unnecessary to carry out preparatory activities.

However, it should be noted that wallpaper, especially expensive natural and fabric wallpaper, are very demanding on the evenness of the walls, and concrete walls are a surface that is completely covered with tubercles and potholes. Therefore, in this case there can be no talk about the quality of work.

For the preparation of concrete surface Before pasting, it is customary to level it with bricks in order to smooth out the main irregularities. After this, it’s time to clean the base with sandpaper and remove dirt and dust. After drying, the walls must be plastered and primed. high-quality composition, which meets the necessary technical parameters.

The primer must have good properties moisture resistance, provide protection against fungus and mold and, of course, firmly bond the wallpaper to the surface. Wallpaper glue performs approximately the same functions. Wallpapering concrete walls can only be done in rooms with low humidity and a complete absence of drafts.

Pasting wallpaper onto paint without preparing walls

To find out whether it is possible to hang wallpaper over paint without preparing the walls, first check the walls for strength. To do this, you will need a simple construction tape; you need to attach it to a wall that is painted, after which it should be torn off with a sharp movement from the wall. If the paint material remains in place and no changes have occurred, then we can assume that the paint has passed the test.

But when inside If there are any paint particles remaining on the tape, this coating will have to be completely cleaned off. This will take a long time, so you need to be patient. In this case, clean the paint with a special metal brush, which is mounted on a drill, or with a spatula. Solvents are very rarely used due to the harmful odor emitted by the chemical.

On a wall that has passed the tape test, wallpaper can be glued without pre-treatment surface, because the paint created a durable, smooth and sufficiently flat surface. Sometimes to achieve rough surface, craftsmen process the paint using sandpaper. Finally, remember that you should not stick light thin wallpaper over dark paint, because dark color will be visible through new finishing, ruining it completely appearance rooms.

Now you have figured out how to apply wallpaper to paint, and are ready to put your knowledge into practice. Each room in your home should have its own personality and unique view, therefore, you should wisely approach the choice of wallpaper and its subsequent sticking. Proper preparation of walls for subsequent wallpapering is a troublesome and rather expensive procedure, but extremely desirable. You need to approach the work with all responsibility, and then the residents of your home will be able to enjoy the results. The updated design will last a long time.

What types of paints exist

In order to carry out the correct set of preparatory work before wallpapering, you must first analyze the paint material on the wall. Therefore, you should find out what types of paints are available and how to work with them:

1. Oil and enamel paint They look similar to each other, they usually have a durable and smooth coating, each has a shine or gloss. To determine it is necessary to chop off a piece with an iron spatula and grind it; oil paint has the smell of drying oil.
2. Whitewashing is determined by simply swiping your hand, after which white marks remain on the palm.
3. Acrylic water-based paint, visually, can be confused with whitewash. But upon contact it leaves no traces. For a more accurate analysis, you can apply water to the surface; the whitewash will become dark; acrylic paint will not change tone.
4. Water-based paint is easily washed out if you wet a rag and rub it over the surface. In addition, like whitewash, it darkens when it comes into contact with water.

Preparing the walls

After a thorough examination of the walls, you can begin to take action. The surface should be smooth without holes and bumps; if there are any, then all defects should be removed. The pits and depressions are filled with putty, all bulges are sanded with sandpaper or a metal attachment for a drill or grinder. Well, first things first.

First of all, you need to understand on what surface gluing wallpaper is not recommended:

1. It is necessary to exclude lime or chalk whitewash, since when wet the whitewash easily comes off the surface. Some workers, of course, experiment with gluing onto whitewash, but first saturate the chalk surface with a deeply permeable primer. But such measures do not provide a 100% guarantee. If for some reason the primed whitewash picks up moisture, it will immediately come off along with the wallpaper.
2. Old and peeling paint under the weight may slide off along with the trellises or partially blow away.
3. The plaster or putty is cracked in places and is coming away from the walls.
4. It is not recommended to apply thin and light wallpaper to a dark base, especially if the wall is stained. Otherwise, all this will appear under the wallpaper.

Wallpapering with oil paint

After all the inspections, you can conduct another test; to do this, stick adhesive tape or masking tape onto the oil-based paint and peel it off with a sharp movement. If there are no traces of paint on the adhesive tape, then we perform the following manipulations:

• the surface of enamel or oil paint must be made rough by rubbing it with sandpaper;
• all potholes and chips are filled with oil putty;
• dust is removed from walls and floors;
• impregnate with a primer with the addition of solvent in a ratio of 1:1;
• For a greater adhesive effect, you can add 1:4 PVA glue to the adhesive solution.

Some craftsmen first coat the walls with liquid glue before gluing. When the surface dries, wallpaper is glued.

Working with a whitewashed surface

In order for the work to be of high quality, it is necessary to wet the walls with water or a special solution and clean them off using a wide spatula. Of course, this is a labor-intensive process, but it is also guaranteed to work. After cleaning work, the surface must be primed with a deep-permeable compound. After the primer has dried, you can safely glue the wallpaper.

If the apartment owner wondered how to glue wallpaper directly onto whitewash, then in principle this is not a problem. To do this, you need to thoroughly saturate the walls with a deep penetration primer. To prevent the chalk from coming off during pasting, it is recommended to apply glue only to sheets of wallpaper. This option will allow only one touch to the wall; if you need to remove and re-glue, then rest assured that all the whitewash will remain on the sheet. This type surfaces are unreliable, and therefore it is necessary to stick only light paper wallpaper with good throughput.

Wallpapering with acrylic paint

Before covering a surface treated with acrylic paint, it is necessary to clean it from problem areas in the form of grease, and then saturate it with a primer mixed with a solvent. This will reliably strengthen all the layers that are applied to the wall. After complete drying, it is recommended to apply an additional primer.

A special acrylic-based concrete-contact primer, sold at any building materials store, is also well suited for this purpose.

How to glue wallpaper on water-based paint

To apply wallpaper using water-based paint, you must perform the following steps:

• sand uneven areas with sandpaper, then putty all problem areas;
• degrease detergent contaminated places;
• saturate the surface with acrylic primer and wait until the walls are completely dry;
• use paper or non-woven wallpaper, as they promote rapid drying of moisture;
• Apply glue to the intended wallpaper.

If you adhere to technological recommendations, then it is necessary to paste onto cleaned walls; this is better than gluing wallpaper onto paint, because it is impossible to analyze 100% the strength and stability of paint over the entire working area. But if you still decide not to remove the paint, then when inspecting the quality of the old paint, pay attention Special attention the top, center and bottom of the wall.

How to glue wallpaper on a concrete base

Concrete walls have pores in the form of small bowls and pits; it is not advisable to glue wallpaper onto such a base; a careful inspection will reveal poor-quality work. Therefore, the walls need to be primed and puttied. It often happens that when wallpapering, folds appear in the area of ​​the corners, this indicates that corner connections uneven. To avoid such a turn, it is necessary to remove them plaster mortar. To do this, throw it into the corners ready mix and according to the plastering rule it is retracted first in one direction, then in the other. If you use plaster with a fine-grained fraction, you can do without subsequent puttying. When the solution is completely dry, you can begin the main process.

How to glue wallpaper correctly

When the surface is completely ready, you can start wallpapering. First of all, you need to cut the sheets to length. After that, the front side of the canvas is laid on a clean floor and glue is applied with a roller. The edges must be generously saturated with adhesive, otherwise when the glue dries, the wallpaper in these places will bulge.

You can start from a window or corner, if it is perfectly level. Some craftsmen also apply glue to the wall just to be sure, but if the wall is primed and the sheet is well soaked, then you can do without unnecessary manipulations. First of all, the edge of the sheet is placed against the corner, and then with a special wallpaper trowel it is smoothed from the middle up and down to remove all the bubbles. It is important to remember that it is not advisable to tear off the glued sheet, especially if there is old paint underneath.

The second sheet is joined to the first, all joints are wiped with a damp cloth to remove squeezed out glue. The main thing is that the first sheet must be laid vertically without the slightest deviation, otherwise the last sheet will lie crooked. When all the whole sheets are glued, you can move on to the pieces above the door, window and behind the radiator.

Tools that may be required for work:

1. Iron spatula.
2. Plastic spatula (for wallpaper).
3. Roller and brush.
4. Sponge or cloth.
5. Glue container.
6. Masking tape.
7. Scissors and a construction knife (a stationery knife is possible).
8. Sandpaper.
9. Drill and nozzle for removing paint (if you decide to strip the paint).
10. Plastering rule (align corners).

Before pasting, it is necessary to remove all sockets and switches, and then cut through the sheet glued to the wall with a construction knife and put the boxes in place.

You cannot open the windows or create drafts while gluing, otherwise all the work will go down the drain; when the glue dries, the room must have a stable temperature.

Some wallpapers have a pattern that will have to be selected. In this case, you need to purchase a spare roll.

The packaging with glue indicates the consumption of the finished solution, but as practice shows, you need to buy 1-2 packs of glue more. If applied to drywall or plywood, it may be enough, but if it is a porous surface, then the mass stated on the packaging will not correspond to reality.

The quality of adhesion will be low, because the adhesion of many paints to other materials is poor. How to hang wallpaper using oil paint? There are a number of techniques to avoid problems and get the job done efficiently.

Features of oil paint

Nowadays oil paints are used much less frequently than a couple of decades ago; they have been replaced by more modern ones - latex, water-based, acrylic. Oil-based paints and varnishes are made from natural or synthetic drying oil. They are quite strong, durable in terms of service life, and tinted well.

Pasting wallpaper directly onto a layer of oil paint has a dubious prospect. Any specialist will say that this is a violation of technology; many problems will arise during the work. These include the following points:

• lack of sufficient grip;
• the likelihood of rapid detachment of the canvases along with the coating;
• the appearance of stains on the finished canvas, especially if thin paper wallpaper is used.

Thus, it is better to get rid of the paint - take the time to remove all without leaving a trace. But pasting wallpaper on paint material It’s still possible; a suitable method exists. It is important to carry out proper preparation walls, and the result will please you.

Determining the type of coating

First you need to make sure exactly what type of coating is present on the wall. Here are the signs different types materials:

1. Lack of shine, dullness, silkiness of the surface means that it is covered water-based composition. It can be removed with a spatula after soaking it well.
2. Appearance on hand white plaque after running along the wall - a sure “symptom” of the presence lime whitewash. Wallpaper cannot be glued to it; it is important to completely remove the lime. Otherwise, after applying wallpaper glue, all the whitewash will fall off.
3. Smooth, shiny, cold to the touch walls are a sign of painting with oil or enamel compounds. They remain unchanged for a long time, do not crumble, and do not fade.

Old coating

Before starting preparatory activities, it is important to carefully inspect the walls. In some places, cracks and spots of loose putty appear on the coating. You cannot leave them, as the wallpaper will simply tear in these places and will look uneven.

In relation to the old coating, the following work must be carried out:

• remove all areas that may fall off (if a significant part of the paint has been removed, it is better to remove the entire layer);
• pull out nails, disconnect skirting boards;
• get rid of any protruding elements.

Get rid of old peeling paint and plaster using a metal spatula, knife or other convenient tool.

Preparing the walls

Before gluing the wallpaper, you will have to carefully prepare the walls. Necessary materials for work - liquid or dry mixtures for putty, primer such as "concrete-contact" or other deep penetration, wallpaper glue, spatulas, brushes, containers.

It is not recommended to buy cheap primers; they will not give the required effect. You cannot replace the ones listed above with others either.

Sanding walls Paste finishing material

possible only after surface treatment. This is required to improve the adhesion of oil paint. The process is based on turning the wall from smooth to rough. You will need to buy coarse sandpaper. It should be used to thoroughly treat the walls on which wallpaper glue is supposed to be applied. After sanding, the walls should be puttied containing gypsum. This is not done in all areas, but where the paint has been removed. Using a spatula, the walls are leveled. Next, sand the putty again and begin priming.

Choosing the Right Glue

To securely fix the wallpaper on the walls, it is important to buy high-quality wallpaper glue. It is recommended to purchase a product designed for the heaviest wallpaper. When gluing simple, lightweight paper sheets, use glue for vinyl or non-woven materials.

The products “Methylane Vinyl Premium”, “Moment Wallpaper Extra”, “Cleo Vinyl” are well suited. The brands also performed well wallpaper adhesives"Econ", "Krost", "Tehpromsnab", different types bustylates. If necessary, glue the material on water with PVA (1:1) or add the latter to any wallpaper glue.

Surface priming

Using a primer perfectly increases the adhesion of old paint and helps increase its absorbency. Many repairmen prefer to prime the walls with a homemade product. They do it like this:

• poured into a container warm water– 1-2 liters;
• add alabaster in small portions, immediately mix thoroughly until the mass becomes similar to sour cream;
• add PVA to the mixture - approximately 1 part to 3 parts of the mass that is already in the container;
• The walls are primed 1-3 times, waiting for complete drying between each stage.

Professionals usually advise difficult cases use the “Concrete Contact” primer, it has excellent penetrating ability. The walls are first washed to remove grease and stains. Then apply the primer in a layer of less than 1 mm and let it dry. Afterwards, the priming is repeated, the walls are dried, and you can begin attaching the canvases.

Wallpapering

After mixing the glue according to the instructions, you can carry out the main process. You cannot change the ratio of glue and water - this will disrupt the quality of adhesion of the materials. Apply the adhesive composition to the canvas using a brush or roller. This rule applies to paper wallpaper. For other types of canvases, apply glue to the wall and wallpaper strip. For glass wallpaper and non-woven wallpaper, the composition is applied only to the wall.

The first strip is applied from the corner located closer to the window. Align the canvas so that it lies perfectly flat. Beginners are advised to pre-line the walls - this will help complete the job without defects. Smooth the cut with a plastic spatula or rag to remove any air bubbles. Next, glue the second sheet, butt-fitting it to the first one. To form beautiful joints, you can use small rubber spatula. Then all the walls in the room are covered in the same way.

The top and bottom edges are cut to fit the baseboards stationery knife, first placing a spatula so as not to damage the walls. Cut out holes for sockets and switches.

Using a sufficient amount of the composition will help reduce the risk of the canvas coming off. If in doubt, it is better to coat both surfaces to be joined with glue, which will help strengthen adhesion. You cannot open the doors in the room, open the windows, or allow drafts to appear during the day - this will dry out faster. Work at high humidity indoors, at temperatures below +15 and above +26-27 degrees, will lead to a lower quality result.

Professionals usually completely remove paint from the walls. At home, you can carry out the work using a simplified method if you try and thoroughly prepare the walls. Then the wallpaper will last a long time and reliably.
