Is it possible to glue wallpaper on old wallpaper or water-based paint. Gluing wallpaper on water-based paint: step-by-step work How to glue wallpaper on water-based paint

As you know, before pasting wallpaper, it is required to prepare the surface in order to ensure the necessary adhesion and avoid peeling of the coating. After all, it is the violation of the working process and insufficient quality preparation that most often serve as the reason that the wallpaper peels off after a short time.

In this review, we will consider whether it is possible to glue wallpaper on water-based paint, and what needs to be done for this.

Surface preparation methods

Let's note right away that just leaving the paint is a rather risky undertaking. Many masters answer in the affirmative the question of whether it is possible to glue wallpaper on water-based paint, citing the fact that such a base is much better than a coating of oil or alkyd compositions.

And this is correct, but it is impossible to guarantee that the layer will behave stably - the finish can last ten years, or it can come off in a year along with the paint. It is better to insure yourself against any unforeseen situations and spend necessary work according to the technology. It will take some time, but the result will be guaranteed reliable and durable.

Removal of non-waterproof paints

Of course, it is best if your walls are covered with ordinary paint that is not resistant to moisture, the work is quite simple and should be carried out in the following sequence:

• The surface is moistened with water using a foam roller or sponge; this must be done neatly and evenly.
• After that, you need to wait 10-15 minutes and you can start removing the coating. You can do this with a spatula, but it is best to use a special scraper to remove paint, with its help the work will go much faster.

The photo shows different types of scrapers, and the choice of a particular option depends on your preferences and the amount of work

• If there are still areas with coating, the moistening should be repeated and walked again with a scraper.
• After that, you should carefully inspect the surface, if there is damage on it, they should be repaired with putty, after which the walls are sanded.
• The last stage is priming the surface with deep penetration compounds, you can choose any option, the main thing is that it is of high quality.

Removing the waterproof coating

If your walls are covered with waterproof or washable compounds, then the process will be somewhat more complicated.

But anyway, any person can prepare the foundation with the right approach:

• The surface must be brushed with a metal brush. It is necessary that there is not a single untreated area, so work especially carefully.
• After that, the walls are moistened, and a draft is created in the room, as a rule, the base is soaked, and after half an hour the paint begins to lag behind, after which it can be removed with a spatula or scraper. If poorly removable areas remain, the whole process is repeated.

• Then everything is done, as in the above chapter - if necessary, the surface is putty and the last layer is applied.

Cleaning walls with a wash

This method appeared relatively recently, but has become very popular among those who carry out repairs due to the simplicity of the process:

• The surfaces are cleaned of dirt, after which a layer of cleaning composition of 1-2 millimeters is applied to it and left for a period of 10 minutes to half an hour, depending on the layer and characteristics of the paint composition. The instruction will tell you what time frame will be optimal.
• After that, the remover is removed along with the paint, and the surface is wiped with a rag. If necessary, the treatment can be repeated, the composition is safe for the bases and does not spoil them.
• Dried base if necessary.

Other ways to prepare walls

There are other methods that are used when preparing the surface with your own hands:

• Processing with a grinder or an electric drill and a wire cup. So the paint can be removed quickly enough, but in the process of work a lot of dust is formed, and even without experience in carrying out such work, not only the paint, but also the layer of plaster or putty can be severely damaged. And in this case, you will have to carry out puttying work on the entire surface, and the cost of materials is quite significant.

• Another option for carrying out work is to use a construction hair dryer. It heats up a small area of \u200b\u200bthe surface, and the paint layer can be easily removed with a scraper or.

So, we figured out whether it is possible to stick wallpaper on water-based paint. As you can see, it is undesirable to leave the coating, therefore, you still have to carry out certain work, otherwise after a few months the layer may begin to peel off in whole sheets.

Advice!
Whichever method you choose, remember that before gluing the wallpaper, the walls must be primed, this significantly reduces the absorbency of the base and improves the adhesion of the wallpaper glue.

A rational solution - in parallel with the repair of the walls. If there is high humidity in the room, then Zinga conductive paint is perfect, and in other rooms you can use Fireproof paints for metal Polistil - they not only perfectly protect the metal, but are also completely fireproof.

Output

We examined how wallpaper can be glued to water-based paint, and why the coating should not be left on the wall. If you still have any questions, the video in this article will help you understand some of the features of surface preparation better.

No one would argue that painting walls along with wallpapering are the most common options. But if you decide to replace the paintwork with sheet finishing for walls of any type - on a paper, non-woven or other basis, then it is important to correctly carry out preparatory activities... In this article, we will look at how to stick wallpaper on water-based paint so that the result is reliable and durable.

Basic base processing options

Features of the preparatory phase directly depend on how firmly the paint adheres, what is the general condition of the walls, and what kind of surface.

Sticking wallpaper directly onto the paint

Pasting wallpaper on water-based paint is not always possible, for a number of reasons.

This option is used quite infrequently; in order not to carry out any work and leave the walls as they are, they must meet the following requirements:

• Excellent adhesion of the composition to the surface, that is, when you try to remove a layer of paint, scrape off its coating, it is removed only together with a layer of putty. Most often, premium products are distinguished by their high strength, it is they who adhere to the bases best of all, and it is much more expedient to leave them than to remove them.
• The walls should not get dirty, dust should not fall off them, even if the layer is strong, but by sliding your finger you can see particles of paint, you will have to remove it, otherwise an unpleasant surprise in the form of peeling wallpaper may appear at any time.

Advice!
Often, when preparing the surface, a layer of firmly adhering paint is sandpapered to make the surface rougher, which improves adhesion, and also allows the primer to penetrate much deeper into the substrate.

Removing the coating with water

If the layer does not hold very well, the coating is damaged in many places and when using not very much force is removed, then it is necessary to remove the composition from the walls. There are several options for the development of events, depending on what paint was used for the work.

If the coating is not waterproof, then the process is carried out as follows:

• The surface is wetted with warm water twice with an interval of 10-15 minutes... The easiest way to do this is with a foam rubber or any other roller.
• After 30 minutes the layer is removed quite well, this should be done carefully, trying not to damage the putty layer.
• If there are areas where paint is poorly removed, the water treatment should be repeated.
• Further continuation of work is allowed after complete drying of the surfaces.

If the walls are painted with a moisture-resistant composition, then the work is somewhat complicated, but still they should be done before gluing the wallpaper.

The technology for removing coating from walls is as follows:

• At first, the entire surface is brushed for metal, do not be too zealous, otherwise you will damage not only, which is fraught with a large amount of unnecessary work and an increase in repair costs.

• Then, again, processing is carried out with warm water, which penetrates through scratches into the lower layer of paint and softens it.
• The next step is to remove the coating with a scraper or spatula, if there are strong areas, the treatment is repeated.

Using other surface preparation methods

You can use other options, consider some of them:

• If you have a hair dryer, then work can be done with it. Everything is quite simple: a small area of \u200b\u200bthe surface is heated, and with the help of a scraper the paint is removed quite easily.

• Can be applied special formulationsbut they are too caustic. In addition, the paint is also removed with the help of water, so it is still not worth using chemistry.
• Finally, mechanical method - with a grinder and wire attachment. This option has a very big drawback - not only the paint is damaged, but also the base.

Preparing the walls

Before gluing the wallpaper, the base, regardless of whether there is paint on it or has already been removed, should be prepared:

• First of all, the plane is cleaned of dust and stains, after which the surface is carefully checked for cracks and irregularities, if any, it is necessary to level it with a putty. If there are a lot of irregularities, then it is easier to putty the surface completely.

In the photo - all irregularities are carefully repaired

• After leveling, treatment with a primer should be carried out, its price is low, but the benefits are enormous - it strengthens the base and does not allow the color of the paint to appear on the wallpaper. The instructions on the packaging will tell you the main features of the application of a particular primer option.
• Another event that can be attributed to preparation is the acquisition of high-quality adhesive composition. It depends on him how firmly the coating will hold, and when doing work with your own hands, reliability is the most important factor.

Important!
If you decide to apply liquid wallpaper, then the preparation of the base will be no different.
The only difference will be in the application of the final coat.

Output

If you do not check the base and stick the wallpaper on an unstable coating, then after a short time the repair will have to be redone, so carefully examine the base and test its strength. The video in this article will help you even better understand some of the issues under consideration.

Repair is inevitable if housing is purchased on the secondary market. The walls in new buildings are clean and there is no thought about how to work with the old finishing material. In an apartment where people have already lived, the walls can be whitewashed, painted, covered with wallpaper. Perfect optionwhen old coatings are removed before plastering. This is especially true if it is wallpaper or oil paint. The whitewash is washed off with water.

Coating with water-based paint raises a number of questions that are best studied before starting repairs: is it possible to glue wallpaper on water-based paint; how the type of CM is recognized, which is already covered by the wall.

The principle of determining the type of dye

Visually distinguish the coating oil paint from water emulsion difficult. The gloss of the coating is the first sign that an oil composition is applied to the wall. Difficulties arise if the coating is matte. Then it is tested.

The sharp end of the staple pushes a layer of finishing material.

• the coating with oil CM can be removed easily, in large pieces;
• the water-based dye is removed together with the putty and poured into a fine powder.

The test suggests that wallpaper can be glued to the water-based paint. It is not necessary to remove and scrape off the dye completely, but the surface of the walls is prepared for gluing the panels.

The test confirmed that the water-based emulsion has good adhesion to plaster or putty, but it may peel off from time to time. You can find out about this more often after gluing the wallpaper. They dry out and pull back the bottom layer of paint. The quality of the new finish is lost.

Checking paint coating for durability

Specialist tips for working with an old layer of water emulsion:

1. It is recommended to completely rinse off a cheap, easy-to-remove water-based coating. It can be removed with water as much as possible. This layer is not strengthened by the composition of the glue.
2. If the quality of the paint is high, then it is better to create a solid base and stick wallpaper on it. Another small test for the adhesion of the KM coating is carried out. A newspaper is glued to the water-based paint, after it dries, you need to try to remove it. Where it is difficult to do this, you can glue the wallpaper without fear. If there are many problem areas, then the old finishing paint layer is removed with hot water.
3. As a rule, it is not the strength of the paint itself that is checked, but the layer of plaster and the finishing putty under it. It is not difficult to wash off the paint. The reliability of the plaster and putty layer is important. Preparatory work add, if, when removing KM with water, the putty begins to peel off. There is a simultaneous check of the old layer of water-based emulsion and the plaster under it.

Preparatory work on the walls covered with water-based emulsion before wallpapering

After testing the strength of the old coating, the method of preparing the walls for gluing is selected:

• paint is completely washed off from the base;
• without removing the CM, the walls are being prepared.

Complete removal of CM

In order to completely wash off the water emulsion you will need: warm water and soft old terry towels. They absorb water well. Towels are abundantly moistened with water. They wash the walls. The more often the walls are rinsed and wiped, the faster the paint will be washed off. If the cloth remains clean after wiping, then the work can be completed. CM is washed off the wall.

Places where the putty and plaster layer has peeled off must be repaired. Shallow recesses are putty, large ones are processed with tile glue.

Preparing the wall without removing CM

The existing CM layer is processed with fine-grain sandpaper. Two tasks are achieved: the wall is leveled and roughness appears. They improve the grip of the wallpaper and the surface. Defects are pre-sealed, dust is removed with a vacuum cleaner, it is better to wipe everything with a damp cloth. After drying, a deep penetration primer is applied to the wall using a wide brush or roller. After 4 hours, additional processing is carried out: a mixture of primer with wallpaper glue is applied (proportion of components 1: 1). Finishing drying takes 24 hours.

The wet base is not covered with wallpaper. In a simple way the degree of its dryness is checked. Small cellophane is fixed on it with adhesive tape for the whole night. There should be no drops of moisture under it in the morning. If, nevertheless, the situation is the opposite, then you need to wait another 24 hours.

The dry walls are ready for wallpapering.

Conditions for choosing wallpaper on walls with a water emulsion

Masters do not recommend gluing heavy wallpaper - vinyl panels. They are thick and even special glue will not be able to hold them on a wall previously painted with water-based paint. Non-woven, liquid wallpaper is recommended. The price of paper for a roll of 10 m with a width of 0.53 m starts from 345.00 rubles and reaches 1000.00 rubles. The base under them is leveled, stains and uneven coloring are removed. It is better not to purchase wallpaper of different thickness. The glue underneath dries for different times, which adversely affects the water-based coating. It is recommended to prepare special bases for this type of panels. They come in two types in rolls: paper base and modified cellulose non-woven fabric. The second type of base is more durable. The adhesive base dries quickly under paper and non-woven wallpaper. A non-woven roll of 10 m with a width of 0.53 m costs an average of 1300-1600 rubles.

Liquid wallpaper is stronger than others. The average price per package is from 300 to 1000 rubles, depending on the brand. Consumption of packaging for 1 m 2 - an average of 3.5-5 m 2. In addition, they easily adhere to the paint and hide surface defects.

But the best option non-woven fabrics remain for covering walls painted with water-based paint. it finishing material high quality, light weight, high performance.

Priming the water-based layer

A water-based emulsion with a weak water-repellent property will flake off if it is too wet with glue. The dye will get wet and will slide off the wall with the new finish.

The base is strengthened with a primer. In addition, the adhesion of paintwork materials and adhesive mixture is improved. Fine quartz is introduced into the primer. The binding components of the primer fix it to the emulsion-painted base. The glue already clings to the grainy primer surface. In the primer, the adhesive elements glue microcracks on the treated wall, thereby strengthening the weak surface areas. Only after such processing will it withstand the weight of the glued canvases.

The surface is cleaned of dust and dirt before applying the strengthening primer composition. The coating is done in 2 layers. Each subsequent one is applied to the dried previous one. Manufacturers indicate on the container the time of complete drying of the coating layer. The duration is also influenced by the temperature of the air, its humidity. A primer is selected that interacts with concrete base... It is recommended to dwell on a white primer, then it will not show through the glued panels.

Many apartment owners prefer to paint the walls with water-based paint - this is quick and relatively cheap way finishes. However, with the next repair and the desire to change something, you have to decide what to do with the previous finish. This is especially true if you are going to change the color of the wallpaper. Let's see if it is possible to glue wallpaper on water-based paint and how best to do it. Let's say right away that such an option is acceptable, but with strict adherence to the gluing technology.

Determination of the type of old coloring composition

In order to properly stick the wallpaper on the water-based paint, it is recommended to make sure that you have correctly identified the type of old paint on the wall before starting work. This is especially true if you purchased an apartment on the secondary market and the previous owners did the repairs. If you stick wallpaper on incorrectly prepared painted walls, over time this will lead to flaking of the material, the formation of air voids and irregularities.

The composition of the paints can vary significantly, so it is not so easy to determine what the walls are painted with. For internal works most often two types of paints are used - water and oil.

If the walls were painted with oil-based paint, it is characterized by a noticeable chemical odor, high water resistance and the formation of a dense solid layer.

If the walls are painted with water-based paint, such a coating is odorless, highly penetrating, and forms a thin film layer when applied.

To determine the type of paint composition on the wall, it is necessary to remove a small area of \u200b\u200bthe coating with a spatula. If the paint peels off in layers, it is oily, if the composition holds well or is removed in small pieces, it is water-based.

Additional testing can be done if the paint adheres firmly to the surface. It will allow you to determine how the painted walls will behave after gluing.

To do this, a small section of the wall is pasted over with newspapers or old wallpaper. After drying, the material is dismantled. If it can be easily removed along with the paint, then it is not recommended to stick to such a coating. If only the paper base is removed and the paint remains on the surface, then it is a water-based paint and wallpapering is allowed.

Choosing the right wallpaper

An important step when deciding to stick wallpaper on a water emulsion is right choice material.

Wallpapers differ in type and thickness, which in turn requires the application of different amounts of glue. If a lot of glue is required and the adhesive dries for a long time, this can lead to swelling and soaking of the water-based paint under the wallpaper.

• Single-layer paper wallpaper can be used for gluing. They are lightweight and allow the adhesive to dry quickly.
• Non-woven wallpaper on paper or vinyl can be glued only after preliminary surface preparation.
• Washable and dense vinyl wallpapers not recommended to choose for painted surfaces. They are heavy and take a long time to dry. With poor adhesion to the surface, they may fall off over time.
• Liquid wallpaper will adhere well to the water-based paint composition. They are highly durable, moreover, they are able to hide existing irregularities or wall defects.

How to prepare the surface before gluing?

Surface preparation is an important and crucial stage that will allow you to get a decent result.

Important! You can work only with those surfaces on which the paint layer adheres firmly and does not flake off.

In some cases, the paint requires immediate removal:

• the composition has low adhesion to the surface;
• the paint is covered with cracks, chips, has severe damage;
• the painted surface is moldy.

To carry out the work, it is required to prepare working materials and tools:

• Primer. It is better to choose acrylic primers for deep penetration. For dark substrates, it is recommended to add a lightening pigment or 25% water emulsion.
• Putty. The mixture allows you to repair minor surface damage.
• Adhesive composition. When choosing wallpaper glue, it is worth considering the type of wallpaper and the volume of the room.
• Finishing material.

The working algorithm includes:

1. cleaning surfaces;
2. checking the flatness of the planes in the horizontal and vertical directions;
3. putty;
4. leveling the putty;
5. padding.

Take a closer look at each step.

Cleaning surfaces

The working space is freed from furniture and interior items for free access to the walls. The surface is cleaned with a stiff brush, dust is removed with a vacuum cleaner. The stains on the walls are removed with special solvents.

An inspection of the grounds is carried out to detect damaged areas, which are carefully cleaned.

Checking planes

The cleaned surface is checked with a building level in the horizontal and vertical direction. This will allow you to identify differences in planes that need to be eliminated by filling.

Putting and leveling

All defects and irregularities on the surface are carefully treated with a putty mixture. The putty is applied with a rubber tipped trowel.

After the filler has set, the surface is leveled. A medium grit sandpaper or a fine abrasive mesh is suitable for this job. Thorough sanding of the walls will allow you to get a smooth surface with high adhesive characteristics.

After finishing sanding, the base is cleaned of construction dust with a vacuum cleaner.

Padding

Finally, the prepared surface is carefully primed. Apply the primer with a soft roller or brush, evenly spreading over the entire substrate. Re-processing is performed only after the previous layer has dried.

Step-by-step process of wallpapering

After surface preparation, you can prepare for gluing.

For work, you will need the following tools:

• building level;
• soft roller and brush;
• construction pencil;
• scissors or knife;
• rubber roller to remove air voids;
• container for glue.

First of all, you need to prepare a comfortable workplacewhere you can lay out rolls, cut strips and prepare glue. Before gluing, the corresponding markings are made on the walls using a building level and a pencil. The markings are vertical lines across the width of the finished canvases.

Important! If the wallpaper contains a decorative pattern, print or pattern, the cutting of the canvases is performed taking into account the joining.

The glue is prepared in accordance with the instructions attached to it in a special container.

1. The prepared strips are laid face down in the appropriate order.
2. The adhesive is applied with a roller over the entire web, the end parts are brushed. There should not be too much glue, but it is also important to avoid dry areas. The processed canvases are neatly folded in half. If the manufacturer provides for additional processing of the walls, do not neglect such recommendations.
3. All work is best done with an assistant. The first canvas is glued strictly in level from top to bottom, observing the wall markings.
4. Next, the glued sheet is leveled over the entire surface, excess glue and air voids are removed. For these purposes better fit elastic rubber roller or spatula. All movements are performed from top to bottom and from the middle to the sides to the joints. It is good to remove the remnants of glue with a clean cloth.
5. The next canvas is glued in a similar pattern - end-to-end, observing the alignment of the pattern (if any).
6. Excess canvases from above and below are cut off with a sharp knife along the joint under a spatula.

To avoid falling off the wallpaper, during the gluing process and after its completion, you must not open windows and create drafts.

Brief conclusion: wallpaper can be glued to water-based paint, subject to preliminary preparation of the walls. The gluing technology itself is accessible and understandable even for novice craftsmen, so all work can be done independently or with the assistance of an assistant.

If we talk about whether it is possible to glue wallpaper on water-based paint, then it is worth noting that much will depend on the condition of the paintwork and on how long ago it was applied. Pasting a painted surface with wallpaper can indeed be performed, but only on condition high-quality painting, lack of flaws and any shortcomings.

Important! It is not recommended to glue the wallpaper onto an old painted surface, even if it is in satisfactory condition. Chances are good that the old coating will not last as long as the new glued canvases.

Not all types of paint can be pasted on wallpaper.

For example, if the coating is made using oil compounds, then you should immediately get rid of them, because they are not different durability.

You can easily determine which paint the surface was painted with.

Usually, two types of composition are used for painting walls:

• Oil. They are distinguished by increased resistance to negative influences, liquids, and a characteristic odor. During staining, the oil formulations lay down as a complete coating, so over time, such paint begins to exfoliate in pieces.

• Water-based. They do not have a characteristic paint and varnish smell, they adhere to the rough surface immediately after hardening as efficiently as possible, so it is extremely difficult to remove paint from the wall before gluing the wallpaper.

Important! You can glue wallpaper only on those painted surfaces that are free of defects and are relatively new (for example, the painting took place several years ago, and not several decades ago).

To accurately determine the type of paint and varnish composition, you can take a spatula and scrape off a small part of the coating in the most inconspicuous place.

• If the scraped material has a crust structure, i.e. it is separated from the wall in layers, then with a high degree of probability it is oil paint.
• If the material is qualitatively connected to the wall, it is poorly and with difficulty scraped off, and it also creates the feeling that the paint and varnish composition is a single whole with the concrete base, then it is a water-based paint.

Removal of the water emulsion is performed using a soap solution (water + soap). The removal process is quite lengthy, so many people decide toglue the canvases directly onto the paint.

Important! Do not glue canvases on walls painted with oil paint. Such a decision would be a big mistake, because a paint and varnish composition of this type, under the load of the adhesive mixture and the sheets, will simply peel off after a few weeks or months.

Preparatory process

Wallpaper on a water emulsion can really be glued, but this should be preceded by a full preparatory process.

Many people want to glue the canvases directly onto the paint just because it is very problematic to remove the water-based composition from the wall. The preparation process includes several main stages.

The surface, which is painted with water-based paint, is smooth and even, therefore, it is not suitable for gluing canvases. Roughing is required. This is done with sandpaper or small scrapers.

With their help, you can remove excess paint and varnish composition and create a roughness, due to which the adhesion characteristics will improve. The treated surface should be washed with soap and water and allowed to dry naturally.

Important! You need to know the approximate thickness of the previously applied paint and varnish composition. If the paint was applied in several layers and was constantly updated, then you should not glue the wallpaper on such a surface. Optimally - no more than 2-3 layers of paint and varnish composition.

Before gluing the wallpaper, you can treat the surface with primers. You need to choose a high-quality primer that will adhere well to the paint and varnish surface and provide good adhesion for gluing wallpaper.

The best option is to purchase a primer with antiseptic properties (it will provide protection against mold and fungal infections).

If the surface on which it is planned to glue the wallpaper has minor chips, cracks and other defects, then they can be removed with a putty solution. If there are serious defects on the surface, then the idea of \u200b\u200bgluing wallpaper canvases on it should be abandoned (it is better to completely remove the paint and apply a new finish on a clean rough surface).

The application of a plaster composition will allow you to qualitatively level the rough base. And the finished surface will serve as an excellent basis - textile, paper, vinyl, non-woven wallpaper can be glued to it.

Important! You do not need to apply plaster if you intend to glue liquid, textured or other types of heavy and thick wallpaper, which by themselves can hide minor irregularities of the black base.

• If you plan to glue heavy wallpaper, then you should first apply special paper.
• If you plan to glue paper or vinyl wallpaper, then you first need to prime the rough base with a high-quality primer.
• It is possible to glue wallpaper on water-based paint if the surface is in good condition.
• If there are many defects and flaws on the painted surface, then you should abandon the idea of \u200b\u200bgluing canvases on it. It is best to completely remove the paint and varnish composition.

To do this, a regular piece of newspaper is glued to the painted wall with wallpaper glue, left in the glued state for a day, and then ripped off from the surface. If the newspaper is difficult to tear off and it adheres well to the base, then there are no obstacles to gluing paper or vinyl wallpaper.

In order to be able to paste high-quality wallpaper on a wall painted with water-based paint, you will need the following inventory:

• Brushes, rollers (soft and rubberized to remove bubbles).
• Scissors.
• Pencil.
• Stationery knife.

Glue application must be done with a brush or roller (depending on the width of the canvases and ease of work).

If it was decided that the canvases can be glued to dispersion or water-based paint, then the work should be carried out in a certain sequence.

If the painted surface, in general, is in good condition and suitable for gluing wallpaper on it, but there are several questionable areas, then you just need to get rid of them. If the wallpaper is glued to them, there is a possibility that the stripes will come off over time, because the paint itself will not withstand the weight of the glue and the applied cloths.

With caution, you need to look closely at the places where there are traces of swelling and chips. All defects of the rough surface must be removed in advance with a putty or paint and varnish composition.

If the painted base is clean, even and free of flaws, then any kind of lightweight wallpaper can be glued to it.

If the painted base is in an unsatisfactory condition, then it is best to get rid of it right away. This can be done using plain water and soap (you will need to prepare a soapy solution). After all the paint has been removed, the walls should be washed with clean tap water.

After removing the paint and varnish composition, the rough base should be primed. Before gluing the wallpaper, the base must dry completely naturally.

If the painted surface is in good condition, but the wall itself is uneven, then leveling work will need to be done. The leveling of painted walls can be done with a putty.

In difficult cases, a special mesh is applied, which is necessary for the adhesion of the solution and preventing the subsequent deformation of the wallpaper.

Important! If the irregularities are minor, then it is best to process them with regular coarse sandpaper. It will not only remove irregularities, but also allow you to create the necessary roughness.

When choosing a primer, it is necessary to clarify its main performance characteristics. The selected primer should work on concrete surfaces and be light-colored.

The priming composition is applied with a roller or brush, in several layers (each subsequent layer is applied after the previous one has dried).

The process of wallpapering a painted wall

You can glue the wallpaper on the painted wall after the complete preparation of the rough base: leveling, roughing, applying a primer.

The features of the gluing process will largely depend on the type of wallpaper selected. It is recommended to glue lightweight types of canvases on water-based paint: paper, vinyl, textile, non-woven, etc.

The principle of work is approximately the following:

1. At the first stage, you need to cut a strip of the required length, and then put it with the pattern down.

2. It is recommended to apply the prepared adhesive composition on the wall and on the canvas, treating the entire area of \u200b\u200bthe strip, paying special attention to the edges. Do not apply glue too abundantly - a thin layer is enough (especially if specialized adhesives are used for vinyl or non-woven wallpaper, with which you can easily glue the canvases even for those who have never done this).

3. Do not allow the adhesive composition to get on the wallpaper pattern. Before gluing the wallpaper to the painted wall, you need to wait a few minutes for the canvas to be saturated with glue.

4. You can start gluing wallpaper from the window or from the most noticeable corner of the room, gradually moving towards the least noticeable areas of the room.

Sticking wallpaper on water-based paint is performed in exactly the same way as on a rough concrete plastered surface.

In the video: Is it possible to glue wallpaper on whitewash.

The main ones are:

• If it is necessary to align crookedly glued stripes, then this can be done with a clean cloth and until the glue hardens. The canvases can be shifted slightly to the side until the adhesive has time to set.
• Before gluing the wallpaper, you can use a building level, a ruler and a pencil to mark the room. This will allow you to glue the cut strips faster and more accurately.
• If gluing of non-woven canvases is supposed, then it is strongly recommended to process with an adhesive not only the cut strips, but also the wall surface.
• If bubbles form under the glued strips during gluing, they can be driven out from under the material using a rubberized roller or a plastic spatula (you can also use a regular rag).
• During gluing and upon completion of all work, you should not open windows, turn on a fan or start an air conditioner - all this will negatively affect the quality of the work performed, or even lead to the fact that after a few days the canvases will simply come off.
• It is not recommended to cover painted walls with heavy types of wallpaper. They will need to apply a sufficiently thick layer of glue, as a result of which a large load will be created on the paint, which can lead to its destruction and flaking. Heavy wallpaper canvases glued directly onto the water-based paint and varnish composition are guaranteed not to last long (even if all the necessary preparatory work is done).

Conclusion

You can glue wallpaper on water-based paint. But professional repairmen and builders do not recommend doing this, because gluing wallpaper linens on a clean, leveled and properly prepared rough surface is a guarantee that the finish will last as long as possible.

If you glue wallpaper on a painted wall, then they can also last more than one year, but in this case, there is a possibility that under the wallpaper, the paint and varnish composition will gradually begin to lose its characteristics and collapse, which ultimately will lead to the wallpaper peeling off the wall.
