Oil paint wallpaper: are these coatings compatible? Can wallpaper be glued to paint? How to stick wallpaper on a painted wall

Reading time ≈ 3 minutes

If guided by technological maps on Finishing work(documents that indicate the sequence of actions), then you can observe the following: any finishing paint coat is applied to the prepared and putty surface. But there are controversial issues, for example, is it possible to glue wallpaper on paint? - yes, this can be done under certain conventions.

The previous coating must be firmly adhered to the plaster layer, and also free from dust, various dirt and other defects. Accordingly, the first stage is surface inspection. It is enough to run your hand over the layer of old paint, as it will immediately become clear where it is lagging behind, and where it is holding firmly, and then carefully clean these places with a spatula or scraper.

There are many compositions of paints, but is it possible to glue wallpaper on water-based paint? - Yes, this is possible, provided that she holds on tightly. But there is a nuance: when the adhesive is applied to such a surface, it grasps with lightning speed, so it is worth pre-treating it with an acrylic dispersion primer, which will remove excessive water absorption. During priming, it can swell in places of poor adhesion - it's okay, you just need to take a spatula and clean them.

As for other surfaces based on oil paint, yes, it is also possible. However, you will have to resort to continuous mechanical processing, in addition to identifying and eliminating crumbling areas. The fact is that the oil formulations form a waterproof coating on the surface that is not able to absorb the adhesive composition. In order to ensure adhesion, the entire surface is treated with coarse sandpaper, thus many small scratches appear - pores into which the glue flows.

You can add 10% PVA glue to the starch glue composition, this will improve the tenacity, but it is best to buy ready-made polymer glue for such a case, with which you can also glue the wallpaper on the enamel paint after the above treatment. Sometimes you can observe the implementation of a sandless coating on an oil surface or enamel, after which a new topcoat is produced.

It is highly undesirable, but you can still glue wallpaper on water-based paint. These paints include old casein glue rolls, as well as whitewash. In the first version, the surface should be checked, as always, and then carefully primed. If there is whitewash on the surface, then it will be impossible to glue the wallpaper on it, you will have to carefully wash it down to the ground (a primer will not help).

There are no special nuances about how to glue wallpaper to paint, it is important to beat off the vertical marking lines of the first canvas on each wall, taking into account the unevenness of the corners. As always when performing wallpaper work, drafts must not be allowed during the day from the moment of gluing; if the surface was painted with oil paint or enamel, the drying time of the glue may increase by 2-3 times.

On a curved surface (oil or enamel), the wallpaper is very difficult to glue, the seams can lag and diverge, and to avoid this, you need to pull the sandless surface. In addition, if the wallpaper is for painting, then everything is even worse: they can peel off in places and the joints disperse during the painting itself.

The decision to use wallpaper as a wall decoration or flow has been considered justified for many years. This option was resorted to many centuries ago, and it is resorted to now, since the modern building materials market offers a huge range of them. But there are certain requirements for the glue process itself. Since the wallpaper is set on glue, it is necessary that the surface on which it is glued has good adhesion characteristics.

Therefore, the question of whether it is possible to glue wallpaper on oil paint is still relevant today. To begin with, when applied, oil paint is well absorbed into the surface to be treated, even if it was applied in several layers. The surface of such a painted surface is glossy, so the wallpaper does not stick to it. Experts advise to get rid of the surface painted with oil paint by any means. The most ideal option is to remove it with sandpaper or a special brush attachment that is put on the drill chuck. Of course, after such an operation, the wall will have to be leveled and prepared before wallpapering it.

But imagine that it is decided to glue wallpaper on a large area. This means that you will have to clean the same area of oil paint. It takes a long time, it is not easy, it is dirty and dusty. Are there any other options? Yes, and there are two of them. True, even in their case, you will have to prepare the surface, and then glue the wallpaper on it.

Option number one

This is the easiest option. To do this, it is necessary to sand the surface of the wall painted with oil paint with coarse sandpaper. Then it is treated with a mixture that includes PVA glue (50%) and a primer (50%). The primer is absorbed into the exposed sections of the wall, forming a bond with the mixture. PVA glue clings to painted areas. At the same time, a thin layer of adhesive composition covers the entire wall, turning its plane into a site with a good adhesion rate. Such a finishing layer dries for at least a day. Then you can start the main process.

Option number two

This is a more complex technology, because you have to strictly adhere to a certain distance between the areas that open between the paints. This requires a spatula, which needs to remove vertical sections of paint in the form of stripes 5-6 cm wide.The distance between stripes can vary in the range of 20-25 cm.

By the way, it is not necessary to remove the paint layer with a spatula. As practice shows, if the paint is attached to the wall tightly and tightly, then it will be very difficult to tear it off without damaging the wall itself. Therefore, you can use a drill with an attachment. The metal brush will only remove the layer of paint and go a little deeper into the body of the wall. After that, these strips are filled with a putty solution to the level of the plane of the painted surface. And then, as usual: putty is sanded, treated with a primer. You don't need to skin if thick wallpaper is glued.

Attention! If non-woven or vinyl wallpaper (thick and dense) is chosen for the decoration of the walls or ceiling, then there is no need to repair and level the walls. They themselves will close all minor defects and drops.

Other options

Home craftsmen experiment all the time, finding sufficiently original and simple solutions... So it is with how to glue wallpaper on a wall with oil paint. For example:

The second option is usually used if the old paint is not in a very reliable condition. Weak unreliable areas will have to be beaten off or removed with a spatula. After that, a material such as "Betokontakt" is applied to the entire surface to be trimmed. This is, in fact, liquid primer, which includes quartz sand. After drying, a layer with a high adhesion rate will appear on the surface. At the same time, the primer applied to the surface to be treated does not absorb moisture from the wall, which makes it possible to dry it evenly, without cracking or flaking.

In the event that liquid wallpaper will be applied to the wall, then the surface must be well washed or cleaned, applied "Betokontakt" (you can use a primer for liquid wallpaper), and only then boldly apply the finishing material. Of course, the condition must be met that the paint itself lies securely on the wall surface. In this case, before starting work, it is necessary to pull out all the nails and screws from the wall, and it is better to paint over the metal mortgages, on the contrary. The goal is to prevent rust from appearing, which will certainly appear on the surface of the liquid cladding.

Wallpaper is considered the most popular and practical among the finishing material, due to its aesthetics and universal availability. of this product... But despite all these positive traits, wallpaper, require a well-prepared surface and adherence to technology during the production process. During cosmetic repairs, many apartment owners are faced with the problem of pasting wallpaper on a painted wall and ask a natural question - how to glue the wallpaper onto the paint. And this is correct and timely, otherwise you can spoil the material and waste a lot of time.

Surfaces are known to absorb odors strongly, especially in the kitchen and in places where people smoke. And in rooms with poor ventilation, mold and mildew can often be found. In this case, it is necessary to carry out cleaning work, if the painted surface is strong and without signs of mold, then it will be enough to wash off the soot and fat detergent... But in case of deep infection with a fungus, it is recommended to clean the entire affected surface, treat with a septic tank, prime and putty.

What types of paints are there

To carry out the correct set of preparatory work before pasting wallpaper, you must first analyze the paint material on the wall. Therefore, you should find out what paints are and how to work with them:

Oil and enamel paint looks similar to each other, as a rule, they have a durable and smooth coating, each has a shine or gloss. To determine it is necessary, chop off a piece with an iron spatula and grind, the oil paint has the smell of drying oil.
Whitewashing is determined quite simply you need to hold it with your hand, after which white traces remain on the palm of your hand.
Acrylic water-based paint, visually, can be confused with whitewash. But upon contact, it leaves no traces. For a more accurate analysis, water can be applied to the surface, while the whitewash will become dark, the acrylic paint will not change its tone.
Water-based paint is easily washed out if you wet a cloth and run it over the surface. In addition, it, like whitewash, darkens in contact with water.

Preparing the walls

After a deep study of the walls, you can start action. The surface should be flat without pits and bumps, if there is one, then all the shortcomings should be removed. The pits and depressions are putty, all the 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 which surface gluing wallpaper is not recommended:

It is necessary to exclude lime or chalk whitewashing, since when wet, the whitewash easily moves away from the surface. Some workers, of course, experiment with gluing to whitewash, but first saturate the chalk surface with a deeply permeable primer. But even such measures do not give a 100% guarantee. If for some reason the primed whitewash picks up moisture, then immediately, it will go away along with the wallpaper.
Old and flaky paint under the weight, can slip along with the trellises or partially blown off.
Plaster or putty is cracked in places and comes off the walls.
It is not recommended to apply thin and light wallpaper on a dark base, especially if the wall is spotty. Otherwise, all this will show up under the wallpaper.

Pasting wallpaper on oil paint

After all the inspections, another test can be carried out; for this, adhesive tape or masking tape is glued to the oil paint and peeled 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 the enamel or oil paint must be roughened by rubbing it with sandpaper;
all potholes, chips are putty with oil putty;
dust is removed from walls and floors;
impregnate with a primer with the addition of a solvent in a 1: 1 ratio;
for a greater adhesion effect, PVA glue 1: 4 can be added to the adhesive solution.

Some masters first pass the walls with liquid glue before pasting. When the surface dries, the 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 it with a wide spatula. Of course, this is a laborious process, but also guaranteed work. After cleaning work, the surface must be primed with a deep-permeable compound. After the primer is dry, you can safely glue the wallpaper.

If the owner of the apartment wondered how to glue the wallpaper directly onto the whitewash, then, in principle, this is not a problem. To do this, you need to saturate the walls well with a deep penetration primer. To prevent the chalk from coming off during pasting, it is recommended to apply the glue only to the wallpaper sheets. This option will allow only one touch to the wall, if you need to remove and re-glue, then be sure that all the whitewash will remain on the sheet. This type of surface is unreliable, and therefore only lightweight paper wallpapers with good permeability need to be applied.

Pasting wallpaper on acrylic paint

Before pasting the surface treated acrylic paint, it is necessary to clean it from problem areas in the form of fat, and then soak it with a primer mixed with a solvent. This will reliably strengthen all layers that are applied to the wall. After complete drying, it is recommended to additionally go through with a primer.

For this purpose, a special concrete primer is also well suited - an acrylic-based contact, sold in any building materials store.

How to glue wallpaper on water-based paint

To paste over the wallpaper on water-based paint, you must perform the following steps:

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

If you adhere to the technological recommendations, then it is necessary to paste on cleaned walls, this is better than gluing wallpaper to paint, because it is impossible to analyze the strength and stability of paint for 100% over the entire working area. But if you still decide not to peel off the paint, then when examining the quality of the old paint, pay special attention to the upper, central and lower parts 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 on such a base, with a close examination you will see poor-quality work. Therefore, the walls must be covered with a primer and putty. It often happens that during the pasting of wallpaper in the area of \ u200b \ u200bthe corners folds are obtained, this indicates that corner joints uneven. To avoid such a turn, it is necessary to remove them with plaster mortar. To do this, a ready-made mixture is thrown into the corners and, using a plastering rule, is first diverted to one side, then to the other. If you use plaster with a fine-grained fraction, then you can do without the subsequent filling. When the solution is completely dry, you can start the main process.

How to glue wallpaper

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

You can start from a window or corner if it is perfectly flat. Some craftsmen also apply glue to the wall for fidelity, but if the wall is primed and the sheet is well impregnated, then you can do without unnecessary manipulations. First of all, the edge of the sheet is attached to the corner, and then it is smoothed up and down from the middle with a special wallpaper trowel to remove all the bubbles. It is important to remember that it is not advisable to rip off the glued sheet, especially if there is old paint under it.

The second sheet is joined to the first, all joints are wiped with a damp cloth to remove the 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 battery.

Tools that may be required for work:

Iron spatula.
Plastic spatula (for wallpaper).
Roller and brush.
A sponge or cloth.
Container for glue.
Masking tape.
Scissors and a construction knife (clerical can be used).
Sandpaper.
Drill and paint stripper (if you decide to clean the paint).
Plastering rule (align corners).

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

You cannot open windows and make drafts during pasting, otherwise all the work will go down the drain, when the glue dries, a stable temperature should be in the room.

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

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

Now you know how to stick wallpaper on paint, following all the recommendations, you can implement it with high quality this work from start to finish.

How to glue wallpaper on oil paint? This question is especially important for owners of apartments from the old stock, where the walls are often painted with oil or enamel paints. Despite the strong and high-quality coating, over time, renovation of the room becomes inevitable, which raises a natural question - is it possible to glue wallpaper on oil paint without cleaning it to the very foundation? This article offers the answer to this question.

Features of oil paint

Such material is made on the basis of ordinary drying oil, which can be:

Natural.
Artificial.

First, the pigment that is available in the color scheme is the most mixed, and then the rest of the compositions are added. The paint is thinned to the required thickness.

The benefits of these coatings include:

High strength.
Durability.

If you want to stick wallpaper on the paint with your own hands, you need to determine its category:

If the wall surface is not shiny, it cannot be wiped off with a wet cloth, most likely, water-based paint was used for coating. It will not work to soak it, but it is possible to remove it with a spatula and not too difficult.
The situation is easier with whitewashing... To determine it, you just need to rub it with your hand, on which a white coating should remain. You should not glue the whitewashed wall with chalk or lime, the coating on such a surface will not hold. But if you remove all unnecessary with a wet sponge or brush, the panels will be held securely enough.
Enamel and oil paints do not react at all to water, they have a smooth, shiny surface.

Tip: Do not glue the wallpaper onto an existing layer of oil paint. But subject to certain surface preparation technologies, this can be done.

How to prepare a surface for wallpapering with oil paint

Before gluing the wallpaper on oil paint, all surfaces must be carefully inspected.

Wherein:

The places of the presence of cracks, peeling layers, which are often removed together with the putty (see How to remove the putty from the walls and how much it is needed) or plaster, are determined. Such defects cannot be left behind.
Be sure to remove all nails, protruding elements, dismantle the baseboards.

Tip: If half or more of the existing coating has been removed after rough preparation, the surface should be cleaned completely. If the main part of the walls inspires confidence, you can use special preparatory techniques.

Before you stick the wallpaper on the oil paint, the wall needs to be sanded, as shown in the photo. It is known that the adhesion of oil paint to other coatings is very poor.

To enhance adhesion, the smooth surface must be roughened.

For this:

Coarse-grained emery cloth you should walk along all the walls.
The walls are treated with a deep penetration primer (see Types of construction primers and their area of application).
The solution is left to dry for 24 hours.
The cleaned areas are compared with a gypsum-based putty (see Gypsum putty: its advantages and problems of use).
The surfaces are washed with warm soapy water. This solution will wash away the grease and allow the paper to adhere better.
To enhance the properties of the composition, a small part of PVA glue must be added to the wallpaper glue.

Tip: Before pasting the wallpaper, the wall should be coated with a small layer of PVA glue diluted with water, give it time to "grab" a little, but, without waiting for complete drying, start pasting.

How to choose the right glue

Before gluing the wallpaper, the correct glue is selected.

It is better to purchase it for wallpapers with a large mass:

Even for thin, single-layer material, a mixture intended for vinyl wallpaper... It can be:

Bustilat;
Moment;
Methylane.

If you are satisfied with the price, it is better to purchase PVA glue. The composition is applied:

in its pure form;
diluted with water, in a ratio of 1: 1.

How to prime surfaces

The main actions in surface preparation should be aimed at improving the adhesion of paper wallpaper on the wall, which consists in eliminating the properties of oil paint to absorb substances poorly.

Work instructions:

Soil "Concrete contact" or quartzite is purchased.
The walls are washed and dried.
The composition is applied, with a layer thickness of about 4 millimeters.
After drying, the surfaces are putty with ordinary putty.
The dried layer is covered with a primer again.
The selected wallpaper is glued to the dried walls.
The primer can be made independently from affordable and inexpensive materials, which can be: PVA glue and
alabaster.

For this:

water is poured into the container;
little by little alabaster is added there, with constant stirring of the mixture;
after the composition reaches the consistency of sour cream, PVA glue is added, while the ratio of the compositions is taken: for one part of the glue - three water.
Well-washed walls are coated with a homemade emulsion and left to dry.

To increase the strength of wallpaper gluing, you need to cover canvases and walls with glue.
Drafts must not be allowed during the work, and after its completion. Windows and doors are tightly closed until the walls are completely dry.
Do not stick wallpaper in hot or cold weather, in the presence of high humidity.

After surface preparation, purchase or preparation of glue, the walls are glued.

For this:

The height of the surface is measured from floor to ceiling.
The length of the wall is measured and the number of strips required is calculated.
The required number of strips is cut, the length of each is taken more by one centimeter.
According to the instructions, glue is applied to the wallpaper. Different glue application methods are used for different wallpapers.
The first sheet is glued correctly. Before gluing it, draw a line with a pencil using a level, stepping back from the near corner the distance along the width of the wallpaper. This line will allow you to correctly and evenly position the wallpaper on the wall.
You need to paste over the room from the corner.
The sheet should be glued from the ceiling, the upper joint is leveled and the sheet is pressed tightly against the wall with a rubber roller or plastic spatula.
The web is smoothed from the center of the sheet to its edges.
The existing folds are smoothed out and air bubbles under the sheet are removed.

Professionals do not recommend gluing wallpaper on painted walls without removing the paint. But if such a decision is made, then it is necessary to properly prepare the surfaces.

After watching the video, you can find answers to many questions.

Preparatory work

Wallpaper is one of the most popular and practical types finishing materials... But for gluing them you need to prepare the surface. Sometimes you may find that the walls are covered old paint... How to glue wallpaper on paint? There is a way out of this situation.

Rules for pasting a room with wallpaper.

First, figure out what paint the walls are painted with.

The option of pasting walls with wallpaper for painting.

There are several types of them. So, for example, oil has a characteristic odor and is water-repellent.

Acrylic water-based paint has no odor, it also repels water well and is absorbed into the surface structure.

If you try to remove the paint with a spatula, the oil paint will fall off easily, and the acrylic paint will only fall off in small pieces. Therefore, the gluing technology in different cases will be different.

Folding wallpaper for better glue impregnation.

Tools and materials:

wallpaper;
glue;
foam roller;
capacity;
hot water;
scraper or spatula;
priming;
construction tape;
putty mixture;
sandpaper.

Preparatory work

Often, in addition to a cracked surface, stains and irregularities, the paint material on the walls also absorbs foreign unpleasant odors (especially in the kitchen). Please note that you cannot glue the wallpaper onto a damp or fungus-infected surface. Process them special means will not be enough. Be sure to find out and eliminate the cause of their occurrence. You can do the following: fix a piece of rolled thermal insulation on the wall surface, then glue on a plastic mesh, plaster or cover with drywall.

Wallpaper gluing on acrylic paint

Be sure to tidy up the surface first. Otherwise, the wallpaper sheet will come off soon. It is necessary to neutralize the old coating. To do this, you can make a solution from a solvent and a primer, mixed in equal proportions, and treat the walls with it. These manipulations will ensure good adhesion of future wallpaper to the wall surface. Wait for everything to dry well and then cover the walls with a primer.

Leave the wall to dry and only then proceed to wallpapering. To do this, mix PVA glue and wallpaper in a 1: 1 ratio. Apply the resulting composition to the sheet and the prepared wall surface.

How to paste wallpaper on oil paint

Self-pasting walls with wallpaper - stage 1.

You can glue wallpaper on oil paint. It has good grip and a very smooth finish. This is what creates difficulties for the necessary adhesion of the canvas to the wall. Therefore, before gluing wallpaper on oil paint, thoroughly treat the surface. In this case, you can resort to one of two possible options. The first is that the wall needs to be treated with coarse-grained emery, then a primer and PVA glue mixed in equal parts should be applied to it.

The second way is as follows. With a spatula, remove the paint in horizontal stripes 5 cm wide every 20 cm, and then apply putty on these places to align them with the entire surface. The stripes are necessary for better adhesion of the wallpaper to the walls. This method is less effective, but sometimes used.

Sticking on paint without surface treatment

Wallpapering the walls yourself - stage 2.

In this case, you first need to check the strength of the walls. To do this, take construction tape, glue it to the painted surface, then tear it off sharply from the wall. If you see that the paint has remained unchanged on the wall, then it has passed the strength test. But if you find particles of the coating on the scotch tape, then it will need to be cleaned off.

This takes time, so please be patient. To clean the surface, you will need a spatula; you can use a special metal brush attached to a drill. It is undesirable to use solvents because of the toxic effect on the body.

In the first case, the wallpaper can be glued without surface preparation, since the coating has formed an even and durable surface... To roughen the surface, it is recommended to sand the wall with sandpaper. Please note: Thin wallpaper of light shades cannot be glued to a dark coating, as it will show through the new finish, which looks very ugly.

Self-pasting the walls with wallpaper - stage 3.

General wallpapering technique

When choosing wallpaper, keep in mind that if there is a pattern on the rolls, it will be necessary to dock it. Buy with 1 roll stock. Before gluing wallpaper to paint, study the manufacturer's instructions for diluting the glue well and strictly adhere to them. Do not use glue that is not suitable for your particular wallpaper.
Wallpaper must be glued from the window. It is advisable to work with an assistant. After cutting off the strip, lay it on the floor with the wrong side up. Spread the glue evenly over the strip, then lift by folding the edges of the sheet together. Wallpaper is glued on top. Align the canvas in relation to the ceiling and attach to the surface. Press the sheet well from the middle to the edges and down. It is advisable to use a rag or roller. With a rag, you can remove the remnants of the glue.
Switches and sockets are glued on top, but immediately cut through.

Wallpaper is glued under the windows and above the door after the solid sheets are glued. Never use hot glue. It takes on a liquid consistency and goes over the edges, staining the front side of the canvas.

If you have a good understanding of how to glue wallpaper on paint, you can safely apply your knowledge in practice. Having done all the work with the utmost responsibility and accuracy, you can get a result that will delight you and your family members for many years.
