The walls are painted with paint like wallpaper. Can wallpaper be glued to painted walls and how? Is it possible to glue liquid wallpaper on paint

Wallpaper is the most popular material for wall decoration and the most versatile solution for interior design. Their diversity is impressive. They differ in structure, properties, appearance.

Traditionally, wallpaper is glued to the cleaned surface of the walls, leveled with putty and plaster. Whether wallpaper is glued to paint, whether it needs to be cleaned off the walls before gluing, and what kind of wallpaper is glued, we will consider in this article.

Often, owners of apartments in old Soviet houses have walls covered with paint, and cleaning the entire surface for wallpapering is a very difficult and time-consuming process. Therefore, you need to determine what paint you can glue the wallpaper on, without fear for the quality of the result. There are such types of paints:

Acrylic is a water-based paint that adheres perfectly to any surface, while absorbing and strengthening in the structure of the wall. It is odorless and water-repellent.
Oil - a finishing material with water-repellent properties, odorless. After the paint dries, a protective layer forms on the surface.

To determine what kind of paint your walls are covered with, you need to glue a piece of tape to the wall and tear it off sharply, or pry off a layer of paint with a spatula. If it will be removed in pieces, it is oil paint, and if it is difficult to remove it, it is water-based paint.

If the walls in the apartment are painted with oil paint, wallpaper can be glued to them. But before proceeding with gluing, it is necessary to clean the surface with sandpaper, and wipe the walls with a sponge, ridding them of dust, or completely remove the paint plates, prime the surface.

Oil paints can hold tightly for years. The only thing is that before gluing the wallpaper to the oil-based paint, you need to perform preliminary work, thanks to which the smooth surface will turn into a rough one.
Glue wallpaper on water-based paint not desirable. You can wash it off with warm water, and then use a putty for leveling. The walls must dry completely, then prime the surface and proceed with wallpapering.

Thus, when the walls are painted with acrylic paint, it is necessary to perform the same steps as when gluing wallpaper to plastered surfaces.

Important! It is forbidden to glue wallpaper on damp walls or surfaces infected with fungus. It will not be enough if you dry out the damaged areas or treat the walls with special means to remove mold.

An effective solution in such a situation can only be the fastening of the heat insulator. It is glued to a special mesh, and then a large layer of plaster is applied or covered with plasterboard sheets.

Determine the type of coverage with which the walls were previously painted.
Remove old coating. Using a metal spatula, remove the paint from the wall surface or clean the walls with a damp cloth from water-based paint. If the paint cannot be removed, the painted surface must be carefully prepared.
Align the walls carefully. Oil paint does not pass the adhesive solution deep into the wall. Therefore, the surface must be treated with an emery cloth. Then the grip of the wallpaper will be strong and durable.
Treat the walls with a primer. Choose only impregnating and deeply penetrating finishing materials. For a better effect, you can dilute the primer with PVA glue.
Choose the right wallpaper. Choose dense wallpaper that absorbs moisture well. It is not recommended to glue vinyl canvases and heavy wallpaper on the paint.
Use adhesive solution for pasting. It is not necessary to grease the canvases very abundantly when gluing. If the walls are processed correctly, then the solution can only be applied to the surface of the walls. If the wallpaper is thin and light, it is advisable to stick it on the lining paper. It is forbidden to glue light wallpaper on dark paint. This finish will change the color of the wallpaper itself.

When choosing and gluing wallpaper that will be glued to a painted surface, you must be guided by the following rules:

Buy the required number of rolls, while taking 1 more roll with a margin.
Dock the canvases according to a drawing or ornament.
Start gluing wallpaper from the window.
To carry out work on pasting the walls together: one person glues the lower part, the other - the upper one.
Having cut off the strips of the canvas of the required length, spread them on the wrong side.
Apply glue with a brush, evenly distributing the solution over the entire surface.
After applying the adhesive solution to the wall and wallpaper strip, start gluing from the ceiling.
Smooth the wallpaper to the edges with a roller or rag.
Remove excess glue.
Glue the following strips end-to-end, not overlap.
Cut the wallpaper sections for switches, vents and sockets with a construction knife.
Carry out the gluing process indoors without drafts.

Inhabitants of the old "Khrushchev" houses must have come across walls covered with paint, on which they so want to glue wallpaper. Preparing a wall for wallpapering is a very long-term task that expends a lot of nerves and forces, so you always want to do without preliminary processing. Can wallpaper be pasted on painted walls? We will learn about this from this article.

Determining the type of surface coating

Before proceeding with pasting painted surfaces, it is necessary to determine the type of material that covers the walls in the room. There are several types of paints used for interior decoration:

In order to make it clear what kind of substance was used, you need to try to pry off part of the coating with a spatula. The oil will go away in a layer, and the acrylic will be very difficult to remove, only small pieces will fall off.

If, nevertheless, it was not possible to determine the coverage, you can use those methods that will help when pasting wallpaper on any coating.

The first option is just taking ordinary wallpaper of any model, except for vinyl and high-quality glue. The surface must be clean, no need to process it. Thus, you can quickly glue the wallpaper, but, of course, no one guarantees the quality with this method.

The second way is priming the painted surface with a quality material. If the surface is primed correctly and with high quality, then you can easily glue the wallpaper onto the painted surface and even lay the tiles on the tiles.

Important! After the surface is primed, you need to putty the unevenness.

Risks of pasting wallpaper on paint

You can glue wallpaper on paint, but you must take into account all the risks that exist with this design:

If it nevertheless becomes clear that the coating is unstable, it must be removed. Here are some tips for doing this:

The paint must be thoroughly soaked with water and constantly moistening, remove the paint layer with a spatula.
Moisten the walls with water and paste with old newspapers on wallpaper glue. After the wall is completely dry, you need to remove the newspapers along with the paint, if possible.
Use special solutions that are sold in hardware stores. They tend to erode the paint structure in a short period of time, and stripping is not a problem.
Removing paint with a sander or sandpaper. This method requires a huge amount of expended physical strength and time.

Algorithm of work

Before gluing the canvases, it is imperative to prepare the painted wall. But there is one universal method that is suitable for surfaces in "Khrushchev". There, as a rule, the walls were half painted, so you need to clean off a 5 cm wide layer of paint with a distance between the cleaned sides of 15-20 cm. The cleaned strips are putty and level with the surface. These stripes must necessarily coincide with the edges of the canvases, since the cuts will better adhere to such a coating.

If this method is not suitable, then we perform the following actions.

Wall preparation

At the stage of preparing a painted wall for wallpapering, you need to perform several actions at once:

Washing the wall. Quite often the walls are painted in the kitchen or hallway, so it is necessary to keep them clean. All dirt must be removed: grease, soot, dirty and dusty deposits. This usually requires only a solution of water and dishwashing detergent. In order to remove the stains that have arisen after washing, the surface must be washed with clean water. If there are no visible dirt and sticky deposits on the walls, then you don't need to wash.

Wall alignment... As a rule, walls are not completely perfect. It is necessary to remove the bumps and putty depressions and cracks. It is very difficult and risky to glue even thick wallpaper onto uneven walls on an uneven wall, let alone thin and paper ones.

Sanding. This stage of preparation applies to those surfaces that are treated with oil paint. On the advice of professionals, you need to walk along the wall with a sander or sandpaper. This process is long, consuming a large amount of effort, but this increases the roughness and adhesion of the wallpaper to the wall. Professionals advise not to skip this step before gluing the wallpaper.

Primer. If it was decided not to do the previous point, then it is easier to prime the wall. This procedure will also help improve grip. It is best to choose a neutral white or gray concrete contact primer. It is designed for such work, and the color will help to hide the real color of the painted wall and prevent the wallpaper from showing through.

If you do not want to spend money on a primer, you can do it yourself according to the following recipe:

Dilution to the state of liquid kefir alabaster or stucco with warm water
Adding 1/3 of the resulting volume of PVA glue to the solution.

You can also mix busylate and PVA glue in a 1: 1 ratio and use this solution as a primer mixture.

Important! The walls treated in this way have excellent adhesion to the wallpaper, so it will be very difficult to remove the covering if necessary.

Sticking wallpaper

After all the work done, you can start pasting. It is imperative to select the glue that is recommended for the selected type of wallpaper. You can read about this in the instructions for wallpaper and glue. A process such as covering the wall with liquid glue and drying it completely will help. After that, you can safely glue the wallpaper.

Another nuance is gluing paper tape on the wall in the place where the joint of the canvases falls. It is necessary to glue it so that after drying, when the canvas dries, no paint is visible in the gap.

Conclusion

Any problem always has a solution. You can paste over painted walls with wallpaper, but you need to prepare them a little. But this preparation will be easier and less time-consuming than removing the old paint coat. Even on a painted wall, the wallpaper will hold up well if the technology is followed.

Very often, when deciding to glue new wallpaper on the walls, a problem arises in preparing the walls for repair. The main problem is the previous paint on the walls. In this case, a serious question arises about the possibility of gluing wallpaper on painted walls. You don't have to peel off old paint. Although this option is fraught with many fears and difficulties. Unforeseen consequences can be expected. But a successful resolution of the issue is possible if the instructions are followed correctly.

It is possible and quite successful to glue wallpaper on painted walls, but this is possible only with the correct and scrupulous approach to business. The first task will be to determine the type of paint with which the walls are painted.

There are several types of paints:

Water-based or acrylic paint. It does not have the ability to repel water, does not have a pronounced odor, interacts well with the surface, absorbs deeply into it, holds firmly, fixing itself in the structure of the material.
Oil paint. It has a peculiar smell, forms a special layer on the surface, and repels moisture well.

Preparing the wall before painting

Before gluing the wallpaper on a painted wall, you need to carefully prepare it for this. The entire success of the operation depends on this. If there are any flaws on the wall, this will affect the quality of wallpaper gluing, as well as the likelihood of their complete falling off the walls.

Stages of preparing a painted wall:

Wall washing. The wall should be washed with soapy water or a little detergent. Then rinse thoroughly with clean water.
Priming the painted wall. It is this procedure that carefully prepares the wall for wallpapering without problems. The primer can be purchased at a hardware store. It is best to take a concrete primer. It is she who best lies on the wall and will bring the expected effect. It is better to choose a light color so that it does not shine through the wallpaper.

How to glue wallpaper on painted walls

There are several different ways to apply wallpaper to painted walls. Each method is quite simple, and the choice depends on the characteristics of the wall itself.

Wallpaper gluing on acrylic or water-based paint

For this type of gluing, it is necessary to update the finish of the old wall. It is necessary to neutralize the previous layer of the substance that was used for finishing. It is necessary to prepare a solution of solvent and primer in a one-to-one ratio. The solvent will be corrosive to the coating and will allow the primer to penetrate deep into the walls. This ensures a strong connection of the new finish to the wall.

It is important to let the wall dry completely. Then the last coat of primer should be applied. This method makes it possible to obtain a special surface with roughness, which will be an excellent basis for gluing wallpaper. When this procedure is done, the wall is dry, you can glue the wallpaper onto the painted surface.

To do this, prepare a special solution: mix PVA glue and wallpaper glue in equal parts. The resulting composition must be applied to the wall and to the very surface of the wallpaper.

Sticking wallpaper on walls with oil paint

This method depends on what the expected end result will be. You can work with oil paints in different ways.

There are two main methods for preparing walls:

Use a spatula to separate the paint from the wall. Then the surface of the wall should be primed.
Sand the surface of the painted wall. This will create special irregularities for the adhesion of the wallpaper, after which the surface should be primed.

The glue should only be chosen if you are confident in the manufacturer. When preparing it, you must strictly follow the instructions so that the glue fully manifests its bonding properties.

It is necessary to take a very responsible attitude to all stages of wallpapering: from carefully gluing the wallpaper joints using paper tape to cutting the corners. You should beware of drafts, a sharp drop in temperature.

Wallpaper application without preliminary preparation

In order to make sure that the walls will withstand this method of gluing, the following check must be carried out. Take the tape, stick it to the wall and tear it off sharply. If no paint peeling occurs, the wall is ready for wallpapering. It is important to pay attention to the tape. If paint remains on its surface, you should not glue wallpaper on such a wall. It will be a waste of time and effort. In this case, the paint must be removed with special tools.

How to paint wallpaper

If special wallpaper for painting has been pasted on the painted walls, the procedure for painting new wallpaper is to be done. Painting doesn't take much time and effort. It is enough to strictly follow the tips and instructions to achieve the desired result.

Wallpaper painting technology is as follows:

It is necessary to prepare materials for painting: paint roller, brushes.
Prepare your work surface. Cover the floor, hide sockets and switches.
Prepare paint for staining.
It is necessary to apply a new strip of paint, mixing it with the old paint.
The walls need to be painted one by one, moving from one wall to the next.
To prevent the paint from drying out quickly, you can use the air humidification technique.

After applying one layer, wait for it to dry and apply further layers as necessary.

If it is necessary to make a quick repair and there is no time for a long and thorough preparation of the working surface, the option of gluing wallpaper on the painted walls is possible. This will save time and effort. However, it should be remembered that this option for gluing wallpaper will not be durable and there is a high probability of swelling and peeling of the wallpaper. In order to avoid trouble, you can follow strict instructions for gluing wallpaper on painted walls: determine the type of paint on the wall, check the quality of its attachment to the wall, thoroughly wash and sand the wall, and prime the surface.

How to properly glue the wallpaper on a painted wall?

Every person dreams of living in a cozy and beautiful apartment. In this case, the interior decoration of the room plays an important role. Usually different wallpapers are used for this. If the renovation is not carried out in a new apartment, then it is important to properly prepare the painted walls before starting the pasting process.

Can wallpaper be glued to painted walls?

Depending on the paint that covers the walls, a further sequence of actions will be selected. Wallpaper can be easily glued to some types. These include:

water-based;
water dispersive;
glue.

If there are areas with paint on the wall that are peeling or peeling, then before proceeding with the gluing process, they must be properly putty with a primer.

Canvases cannot be glued to walls that have previously been treated with paints that create a smooth surface or a moisture-proof film. Among them are such types of paints as:

latex;
moisture resistant;
oil;
alkyd and pentaphthalic enamels.

To ensure a secure bond between the material and the wall, these types of paints must be completely removed. If this process is too laborious, and also takes a lot of time, then you can try sanding the surface, and then apply a primer to it.

Conditions for gluing

Before you start wallpapering walls, several factors must be considered. The reliability and durability of the new coating depends on them.

When the walls were being painted If this happened a very long time ago, then there is a high probability that the canvases will lag behind the wall along with the paint.
Does the plaster hold well? If it is old, then there is also a risk of collapse.
The cleanliness of the walls. Before you start gluing the walls, you need to wash them well from dirt and dust.

To achieve maximum adhesion between wallpaper and paint, it is necessary to sand it with sandpaper. After which it is washed and dried thoroughly. Only then can you start wallpapering. In this case, you do not need to use a lot of adhesive. This can cause yellow spots to appear on the wallpaper.

How to stick wallpaper on a painted wall?

When the wall is not sufficiently prepared or there are flaws on it, then all this will then appear on the canvases. In some cases, they can even move away from the wall.

The main stages of preparation include:

Washing the wall. To do this, it is better to use soapy water or simply add dish detergent to the water. After all the dirt has been removed, the wall can be washed off with clean water.
Padding. Thanks to this procedure, a reliable adhesion of paint and wallpaper is guaranteed.

For interior work, it is better to buy a concrete primer. In this case, the color should be light tones. It can be found in any hardware store.

What wallpaper can be glued?

Today the stores offer a huge number of different wallpapers. But not all types are suitable for painted walls. It is recommended to immediately exclude simple paper and vinyl canvases. It is better to pay attention to wallpapers such as:

Non-woven. They absorb glue well, so the risk of paint getting wet is almost completely eliminated, as a result of which it can simply fall behind the wall.
Cloth or vinyl. It is desirable that they be on a non-woven base. They will not only look luxurious in any interior, but also have all the positive properties of conventional non-woven fabrics.
Liquid. A distinctive feature of the coating is its fast drying. Therefore, the composition does not have time to penetrate deep into the paint and dissolve it. These canvases can be applied even to uneven surfaces.

All types of finishes are presented in a wide range. Each person will be able to choose the ideal option for their apartment.

Which glue to choose?

The quality and strength of the bond will depend on the quality of the glue. If the wallpaper will be glued to a painted wall, then it is better to choose a polyvinyl acetate emulsion for this.

How is pasting done?

The way in which the walls are pasted depends on what paint is covering them. Each of them has its own characteristics, but does not represent anything complicated or time consuming.

Acrylic or water-based paint. The top layer of the surface is removed with a solution of solvent and primer in a 1: 1 ratio. After which it is necessary to allow time for drying. Next, a primer is applied so that a roughness appears on the wall. This will provide a secure grip on the wall and wallpaper. They begin to glue the canvases only after the building material dries well.
Oil paint. Before you start gluing wallpaper, you need to remove the old layer of paint. This is done with a spatula. When the paint is removed, the wall must be carefully primed. After all the composition has dried, the surface of the wall is treated with sandpaper. Then again a layer of primer.

If the paint applied to the walls is distinguished by bright and catchy colors, then even the densest wallpaper will not be able to cover it. Therefore, in this case, the only correct solution would be to completely remove the old coating.

When in doubt that the paint on the wall will withstand the new finish, a little experiment is recommended. To do this, take an adhesive tape, attach it to the wall with the adhesive side, and then tear it off sharply. If at the same time the paint does not begin to peel or crack, then new wallpaper is glued on top of it.

How long does it dry?

Depending on the type of wallpaper and the quality of the glue, the drying time of the surface varies.

vinyl canvases with a flesilin base dry from 24 to 48 hours;
the rest dry out within 18-24 hours.

The first 1-2 days, only moisture is returned. Only after this time, further polymerization of the adhesive begins.

Care of the glued surfaces will directly depend on the type of wallpaper.

Vinyl canvases. They differ in quality, which determines the density, wear resistance, moisture resistance. You can keep it clean by wet cleaning. The wallpaper does not need to be rubbed hard or use additional hardware to avoid damaging the wall. Cleaning is recommended from time to time.
Paper wallpaper. Do not use water and soap solutions in leaving. Cleaning takes place with a vacuum cleaner and dry rags.

If the wallpaper was glued in rooms with high humidity, then mold or mildew should not be allowed on them. In this case, you will have to remove the finish and process the contaminated surface.

The most popular and practical type of wall decoration today is wallpaper, but often gluing them causes difficulties, especially when the surface has previously been painted or whitewashed. Removing the old coating is sometimes laborious and time-consuming, and few people are attracted by the prospect of spending so much of their energy on a rough finish if only a simple cosmetic repair was planned. In this article we will talk about whether it is possible to glue wallpaper on paint and how to do it correctly without much effort.

Determine the type of paint

In order to correctly determine how to prepare the surface for gluing, it is necessary to find out the type of finish applied to it. There are 2 types of them:

Acrylic water-based paint is odorless, absorbed into walls and firmly fixed in the structure.
Oil paint - has a specific odor, repels moisture and forms a “protective layer”.

In order to understand whether it is possible to glue wallpaper on oil paint or acrylic, you need to find out what type of coating you are faced with. There are several ways to do this.

Method 1

Using a spatula, try to remove some of the covering from the wall. In case it is an oily coating, the material falls off in large pieces. It is easily removed and does not crumble. The acrylic coating, unlike the first option, adheres tightly, crumbles and falls off in small parts.

Method 2

Dampen the surface with lukewarm water for 15 minutes. If the surface easily absorbed moisture and washes off with a sponge, then this is an acrylic water emulsion. If the water just drips off, and the coating itself has a glossy surface - most likely, you have an oil coating in front of you.

Now that we have determined what type, let's talk about how to glue wallpaper on paint, because the gluing technology depends on what we glue on.

Preparatory work

Before starting the main work, you need to carefully prepare for it. To do this, prepare:

Wallpaper;
Glue;
Foam roller;
Scraper or spatula;
Hot water;
Putty knife;
Priming;
Capacity;
Putty mixture;
Sandpaper.

Important! Before starting work, assess the condition of the walls. If they are damp, dirty, covered with mold, then it is impossible to work in such conditions. Before you start gluing, you need to dry them, get rid of unpleasant odors. The mold is removed using special means, and its source is removed.

Choosing glue

A very important part of the work is the choice of glue, because it depends on it how strong and long they will hold. The best option is to purchase heavy wallpaper glue. Among them:

“Bustilat”;
"Moment";
"Methylane".

Important! Do not forget that there are specialized adhesives for each type of coating. Observe the manufacturer's recommendations.

Choosing wallpaper

There is often an opinion that you can choose any coating you like and glue it exactly. But everything is much more complicated. If you have to glue wallpaper on paint, then you need to adhere to some rules. For example, light and thin materials are not suitable for this type of work, especially if the surface is dark in color. If you want to glue just such, then the wall must be carefully prepared before that. To do this, you need special lining paper. With its help, you will remove all irregularities and roughness, and also hide the color of the surface so that they do not shine through.

Important! If you are covering the walls with cladding paper, it is very important that the seams of the wallpaper and paper do not match. It is recommended to glue them from the middle of the paper.

Preparing the wall for gluing

We found out that it is possible to glue wallpaper on paint, but before that you need to properly prepare the surface, depending on what was on it before the repair. Let's take a closer look at each option.

Oil paint

Such paint has its own specific features, namely, it has a very smooth surface, which does not give the material sufficient adhesion to the wall. In order to stick wallpaper on oil paint, the wall must be prepared in one of the following ways:

In order for the surface to become suitable for gluing, the walls must be treated with coarse emery, and later apply a mixture of glue and primer to it in a 1 to 1 ratio.
The second method is less expensive and less reliable, but it also has a right to exist. Namely, in order to be able to glue the wallpaper onto the paint, use a spatula to remove the coating layer from the surface with horizontal stripes. Each strip should be approximately 5 centimeters wide and spaced every 20 centimeters. Next, use the putty to level the wall and proceed to gluing.

Important! Sticking this type of finish on oil paint is practically no different from sticking on a regular wall, except for the adhesive. For its preparation, wallpaper glue needs to be taken 2 times more than PVA glue.

Water-based paint

We have already decided whether it is possible to glue wallpaper on acrylic paint. Let's talk about how to prepare the surface for gluing. For this:

Prepare a mixture with the following composition: solvent plus primer in a 1 to 1 ratio.
Apply this mixture to the wall. The solvent will corrode the top layer of the emulsion, and the soil will be absorbed into the wall.
After the wall is dry, apply the primer again to create a roughened surface that will adhere firmly to the wall.
After the wall dries, proceed to gluing.
Use a 1: 1 ratio of PVA and wallpaper glue.

Can wallpaper be glued to paint without surface preparation?

If the repair needs to be done faster and there is no time to process the walls, there is another way out. In order to determine the strength of the walls, you will need to take a strip of construction tape. Stick it to the wall and tear it off sharply. If there are no traces left on it from the surface, then the wall has passed the test, and you can glue the wallpaper onto the paint. Otherwise, the coating will need to be cleaned off.

Important! To roughen the surface, sand it with sandpaper.

Wallpaper gluing on whitewash and enamel

In addition to paints and varnishes, the wall can also be treated with enamel or whitewashed. Let's talk about what to do with the wall in such cases.

Whitewash

If the walls were whitewashed, then you have to work hard, because the whitewashing will need to be completely removed from them. For this:

Prepare a mild soap solution.
Apply it to the wall and let it soak a little.
Remove the whitewash with a spatula.
Rinse off any residue with a sponge.
Check if everything was removed. To do this, slide your palm along the wall. If at least a drop of chalk remains on your hand, then the wall must be washed again.

The second method of preparing whitewashed walls is also not easy. For this:

Treat the surface twice with a deep penetration primer.
Then prepare the glue diluted with water in a ratio of 4 to 1.

Concrete walls

Many developers and just people living in apartments often assume that the concrete wall does not require preparation before gluing. In fact, this is far from the case.

Important! Only in rare cases is it possible to perform this manipulation with low humidity and no drafts. At the same time, do not forget that not all types of wallpaper can be glued directly onto concrete. Observe the manufacturer's recommendations.

In order to completely protect yourself from unsuccessful repairs, it is better to process concrete walls in this way.
