It’s even scary to remember all the subtleties of wallpapering that our parents had to deal with - as a rule, at that time the walls were decorated without prior preparation. The maximum that was done to improve the quality of wallpaper stickers was the preliminary “leveling” of the walls with newspapers, in this way the roughness of the plastered surfaces was reduced and premature peeling of the wallpaper was prevented. Today, the preparation of walls for wallpapering is almost of paramount importance - and no wonder, because a lot depends on this process, and first of all, how long such a wall covering will last. In this article, together with the site stroisovety.org, we will study in detail the technology of preparing walls for pasting them with wallpaper and learn how to do it with our own hands.

Preparing walls for wallpapering: four reasons why you need to do it

There are a lot of reasons not to ignore the process of preparing walls for wallpaper - listing them all is simply unrealistic. The main ones are the following.

Firstly, this is the most important thing - the quality of gluing the canvases. It has already been said above that the porous surface is simply not able to hold the wallpaper on itself for a long time. The reason for this is simple - where there is time, the base of the wallpaper is not glued to the wall. As a result, only 50 percent of the canvases are glued - this is easy to verify when faced with the dismantling of wallpaper glued to an unprepared wall. They come off as if by magic. By the way, for the same reason, already during the first month, the seams between the individual strips of wallpaper begin to open. It should be remembered that earlier almost all wallpapers were glued with an overlap - it turned out that one strip held the other, but now they are glued joint to joint.

Secondly, it is the unevenness of the walls. If one of you thinks that they will hide under the wallpaper, I hasten to assure you of the opposite - even the most dense and thick wallpaper is not able to hide bumps and pits. It's all about lighting - even if such flaws are not visible when the chandelier is on, they will definitely appear in daylight. Or vice versa, here how the card will fall.

Fourthly, adhesion (the ability of materials to combine with foreign substances), simply put, this property of materials is fully responsible for the duration of the wallpaper on the walls.

These reasons are quite enough so that the preparation of walls for wallpaper is not ignored. Many, of course, can argue with these arguments and oppose them with their arguments, they say, all the same, the wallpaper is re-pasted every 3-5 years. I will answer simply - that's why they are re-glued, because the preparation of the walls for wallpapering has not been completed. In addition, the wallpaper itself does not differ in quality and quickly falls into decay. Expensive wallpapers with proper gluing can last at least ten years or until they get bored.

How to prepare walls for wallpaper: work sequence

We will not beat around the bush, but consider how the walls are prepared before wallpapering, as they say, point by point.

1. Wall primer. This operation is necessary for three reasons.

Firstly, a deep penetration primer penetrates the wall and holds its surface layer together, thereby preventing small particles of plaster or concrete from peeling off.

Secondly, the primer composition deprives the wall of the ability to intensively absorb moisture, thereby increasing the drying time of subsequently applied putties, which affects the quality of the coating. It should be understood that the rapid drying of all mortars does not lead to anything good - at least the surface will crack.

Thirdly, the primer simply removes dust - and, as you know, nothing sticks to it. The primer is applied with a large brush or brush - it must be rubbed into the surface until a white foam is obtained. Before moving on to the next step, which involves preparing the walls for wallpapering, you need to wait for the walls to dry completely.

Why prime the walls

1. Sealing of cracks and potholes. You should not hope that the subsequent puttying of the walls will solve the problem with cracks and potholes - it will hide them superficially, and these defects will certainly return in the very near future. The crack should be enlarged to about a centimeter width, after which they should be opened with a primer and sealed with cement mortar, and preferably with glue for tiles.

It should be understood that cracks in the plaster do not just appear - this is a sure sign that in this place the plaster has lagged behind the base of the wall. You may have to work hard with a hammer and remove the falling plaster. This is where problems can arise - old plaster can crumble in large pieces, and then preparing the walls for wallpapering will result in a major overhaul, which involves leveling the walls with plaster again.

But let's get back to our wallpaper, or rather, to preparing the base for gluing it - we wait for the repaired areas to dry completely, prime them again with high quality and proceed to the next stage of work.

1. Wall putty. You can’t do without it - you will have to apply at least a thin layer of putty on the walls. And the point here is not at all the leveling of the surface, although this factor is also important. Puttying is necessary mainly in order to reduce the surface roughness and increase its bonding area.

Ideally, of course, it is necessary to level the walls, but in most cases this is practically unattainable for non-professionals, so the task is set as follows - with the help of putty, you just need to smooth out all the bumps. It should be understood that the finishing putty is applied only in thin layers, since large ones will crack as they dry.

Irregularities are eliminated in several passes - to make the wall even, professional plasterers sometimes have to putty the wall three, four, or even five times. After the putty has completely dried, all flaws in the form of tubercles and sagging are mechanically removed from the surface of the walls - an abrasive mesh is used for this purpose. In principle, it is possible to remove small protruding putty deposits with a spatula.

1. Well, the last stage of work, which involves the preparation of concrete walls for wallpaper, is again their primer. I want to note that in order to achieve high quality of any work related to gluing, puttying, plastering and other similar works, a primer is almost always performed. To exaggerate, it looks like this - took a step, primed, took the second step, primed again, etc.

Each layer of the cake applied to the wall must be primed without fail. The same applies to painted surfaces, which are quite common in old apartments - only in this case you need to use a primer called "betonokontakt" or the like.

That seems to be all - after priming the putty walls, which reduces their ability to quickly absorb glue and removes dust residues, you can proceed to the direct wallpapering, but first, of course, you must wait for the primer to dry completely. Preparing the walls for wallpapering ensures that the new coating will not only have an attractive appearance, but will also serve you for a long time.

Wallpaper is still the most popular finishing material among many alternatives. It would seem that every adult at least once had to take part in wallpapering, and therefore what questions can there be regarding this process?

Nevertheless, it is still rare to meet a wall perfectly pasted over with wallpaper. Many sin on the manufacturers of the material, they say, for the sake of economy, they produce wallpaper from low-quality raw materials, or they suggest paying attention to where the hands of the master who carried out the repair work grow from. All these comments have the right to life, but according to the observations of professionals, most of the problems and shortcomings are related to the preparation stage, and not at all to the wall finishing process. Therefore, in today's article we will tell you how to prepare the walls for wallpapering with your own hands and give step-by-step instructions for this process.

Many people ask why prepare and process the walls before wallpapering at all. We will answer with a story about what awaits you and your repair, if you decide to ignore this stage:

• The wallpaper simply does not adhere well, because there are pores on the unprepared wall, the presence of which leads to voids between the wall and the wallpaper, and therefore the material will sag and hold loosely. When you start preparing the wall and begin to peel off the previous layer of wallpaper - pay attention to this, the coating glued to the unprepared wall will be removed very easily;
• By hanging wallpaper without preparations on concrete walls, you run the risk of being very surprised at the completion of the repair by how uneven your walls are, and the wallpaper is completely unable to hide this. In order not to get into such a situation, the walls must first be leveled;
• Harmful microflora in the form of fungus and mold does not always form on the walls of abandoned premises, it is enough just to leave microcracks and not prime the walls and these unpleasant companions will settle in you for a long time.

Preparing the tool for work

To prepare the walls for wallpapering, we need the following materials and fixtures:

1. Starting and finishing putty, with which we will level the walls and make the last layer before the wallpaper.
2. Primer, optimally - deep penetration.
3. Serpyanka, we will repair cracks and close the seams with her.
4. To apply putty, you will need to use spatulas, you may need tools of different sizes.
5. The primer and the container in which it will be located during work.
6. Brushes and rollers, for applying a primer, respectively.
7. Various rags

Work sequence

Cleaning surfaces from old materials

As mentioned above, first you need to remove the old finishing material, otherwise it will not be easy when gluing and subsequent operation of the wallpaper. If you have to rip off the old layer of wallpaper, then proceed as follows:

If you have to remove water-repellent wallpaper - before carrying out the procedure described above, first make cuts on the wallpaper, otherwise they will not absorb moisture. If you have to shoot the so-called liquid wallpaper, then you should arm yourself with an industrial hair dryer and preheat them.

If the wall is to be cleaned of old paint, then depending on the type of paint, we will need different tools. Since it is likely that you do not know what kind of paint was applied by the previous owner of the apartment, you will have to try different methods and look at the effect. In general, there are three main methods:

1. Mechanical, that is, a banal physical impact on the coating with a scraper or puncher with a special nozzle;
2. Heating, here you need a heat source like an industrial hair dryer;
3. Chemical - the use of special means to remove paint.

Primary primer

Regardless of the type of wallpaper that you plan to apply, you must first treat the walls with a primer - this will facilitate the gluing procedure, as well as help the walls absorb less moisture and protect against mold. It is applied with a brush or roller, the main thing is to do it carefully and conscientiously, without missing hard-to-reach areas. If you see that the composition is absorbed into the wall almost instantly - apply another layer.

After that, the walls should dry thoroughly, the time required for this depends on the type of primer, but it is better not to rush and not start plastering earlier than in a day.

Plaster

Unfortunately, the walls in a standard Russian apartment leave much to be desired, and therefore we cannot achieve it without plastering and leveling the surfaces. The choice of plaster mixture depends on the type of walls - brick should be covered with cement-sand, and concrete walls should preferably be equalized with gypsum mixture. If you are going to glue dense, for example, vinyl wallpaper, and the unevenness of the walls is insignificant, you can do without plaster, but you will not be able to mask serious curvature with wallpaper. The plastering process is as follows:

1. We prepare a solution from the purchased mixture according to the instructions, it is most convenient to do this with a drill with a special nozzle;
2. We apply the resulting mass to the wall and tear it with a thin layer using a profil or a large spatula until all cracks and irregularities are eliminated;
3. Let the plaster dry, after which you can proceed to the stage of puttying.

putty

This stage is extremely important, because putty will reduce the roughness of the walls, which will have a positive effect on gluing wallpaper. Before starting work, it is worth protecting the floor from the inevitable dirt, and therefore we lay oilcloth or other unnecessary material, now you can proceed:

1. We carefully grind the wall, after which we apply a putty layer starting from the bottom, which helps us with a spatula, and then we level it.
2. We are waiting for drying, after which we re-grind the wall, making it as even and smooth as possible;
3. We shake off the dust formed on the walls or remove it with a vacuum cleaner. Wall putty finished.

Re-priming walls

In the end, it is worth repeating the priming process described above. Now it will be easier to do this and less primer will be needed, because the walls have already been prepared. Often, glue well dissolved in water is used as a finishing primer, which will later be used to fix the wallpaper. Having carefully smeared our surface, we will complete the preparation of concrete walls for wallpapering. As you have seen, the wall preparation technology does not require unique skills at all, and therefore everyone can prepare the walls for wallpapering with their own hands.

Above, the stages of preparing the walls for wallpapering in an apartment belonging to the secondary housing stock were described. Many people think that, having entered a new building, such difficulties will not arise - this is both true and not true. Yes, you don’t have to rip off the old finishing materials, but no one guaranteed smooth walls, therefore we inform you how to properly prepare the walls for wallpapering in a new building:

1. Throw a layer of plaster of a creamy consistency up to 1 centimeter thick on the wall;
2. After the first layer is sprayed, dried up, apply and carefully level the second layer up to 0.5 cm thick;
3. The last layer - covering, should have a thickness of 0.2 to 0.4 cm, after drying it must be carefully rubbed and at the end we will get smooth walls.

Another non-standard situation is the use of liquid wallpaper. You can prepare the walls for sticking such wallpapers with your own hands not only by leveling, puttying and bending the walls, but also by painting them. We advise you to give preference to white tones, otherwise the paint may subsequently shine through the wallpaper. After such preparation, liquid wallpaper will lie down easier and will hold on to the wall more firmly.

With all the variety of modern finishing materials, wallpapering the walls remains the easiest and most inexpensive way to update the interior. Vinyl and paintable, photo wallpaper, glass wallpaper and liquid - the choice is yours. Preparing the walls for wallpaper is the most important step. Resist the temptation to stick new wallpaper on the current, or on a painted wall: the old coating will inevitably crack, swell, spoil the look of the room. In the old housing stock, the walls are not perfectly even, and the corners are far from straight. Invest a little money and effort into surface preparation and you won't see the new wallpaper warp with the old, or follow the curvature of uneven walls. Preparation is divided into several stages.

Dismantling of old material

If you are going to update the interior, where the wallpaper was previously pasted, then they need to be removed. De-energize the room so as not to get an electric shock: when removing wallpaper, you will use sharp tools and wet the walls. Lay newspapers on the floor, take out furniture, or cover it with a film. Removing the old coating is a messy and time consuming process, but it can be made easier by knowing a few tricks.

• Find a section of the wall from which the wallpaper separates well. Pry the canvas with a spatula or knife and gently pull. It is not necessary to pull sharply, the old coating has become brittle. It's fine if you can strip off entire strips of trim, but you're more likely to come across areas of the surface where the wallpaper is very secure.
• Firmly glued wallpapers can be removed after soaking them. Treat the surface with warm water from a spray bottle or roll with a roller dipped in hot water. Remove the soaked coating with a wide spatula.
• Before soaking washable or vinyl wallpaper, roll it with a roller with metal spikes, this will break the moisture-resistant film. If there is no such tool, cut the surface with a sharp knife.
• If the old coating was glued to the PVA, you can remove it with laundry soap. Grate a bar, pour three liters of water and bring to a boil. Treat the walls with a roller or sponge, after 20 minutes you can remove the wallpaper.
• Vinegar, dissolved in hot water, will cope with both PVA and construction adhesive. Dilute a crushed piece of laundry soap and 400 ml of vinegar in a bucket of boiling water. Process 1.5-2 m 2 of the wall, after 20 minutes start work. If some areas do not lend themselves, they will have to be cleaned with a metal brush or moisture-resistant sandpaper.
• After removing the wallpaper, wipe the wall with a sponge dipped in clean water, this will wash off small particles of paper, glue and detergent residue.
• If the old glue turned out to be of very high quality, steam the surface. Attach a wet cloth to the wall, iron it with an iron at maximum power. An iron with a steam generator or a household steamer will do this task even better. After removing the coating, dry the walls to prevent mold.
• In hardware stores you can buy a special wash. Apply it on the walls, leave for 2-3 hours, then remove the wallpaper with a spatula or a wide knife.

Removing old paint

Oil paint forms a smooth surface with poor adhesion, and water-based paint under the influence of wallpaper glue will begin to bubble. Oil paint can be removed with a blow dryer and a spatula, or washed off with a special old paint thinner. The water emulsion can be soaked with soapy water and cleaned with a spatula.

Surface priming

After removing the old coating, the walls need further processing. Regardless of what the next stage of work will be, you need to prime the surface, which will allow:

• Reduce the consumption of wallpaper glue;
• Increase the service life of the finish coating;
• Give the surface uniformity;
• Improve adhesion.

Choose a primer suitable for the surface of the walls. Acrylic is intended for puttied and plastered walls, alkyd for wooden ones. The primer is applied using a construction roller, in the corners you should use a brush. After the first layer is completely dry, apply the second. The primed walls are smooth and slightly sticky.

Surface plastering

It is necessary to carry out in cases where there are significant irregularities in the walls. Inexpensive plaster mixes are produced on the basis of cement or gypsum. It is easier to work with gypsum compositions, they are more plastic, have a fine grain size, but are not intended for rooms with high humidity. Acrylic and latex compounds can be used in any room, but they are quite expensive, so they are used as putty to level small irregularities.

Operating procedure

On a pre-primed wall, install construction beacons according to the level. Follow the manufacturer's instructions - the package indicates the minimum and maximum layer thickness and the time for complete drying.

• Between adjacent beacons with a trowel, throw a plaster mix.
• With smooth movements from bottom to top, and from left to right, using the rule, stretch the plaster.
• Add the mixture to the resulting voids, and remove the excess with a spatula.
• After the walls have dried, remove the beacons and plaster their installation sites. It is impossible to leave lighthouses in the thickness of the plaster, over time they will rust, and stains will appear on the wallpaper.

If smoothing and glossing was not carried out during the plastering process, the surface will be grainy and uneven, it is impossible to glue wallpaper on such walls.

Surface putty

After the plaster has dried, prime the walls and proceed to putty. This procedure is carried out in one or several stages, depending on which wallpaper is chosen for pasting the walls. Thick vinyl wallpapers with a pronounced texture do not require a perfectly smooth surface. For pasting walls with thin and smooth wallpaper, you will have to carry out both basic and finishing putty. The finely dispersed structure of the putty mixture evens out the graininess of the plaster layer.

To work, you will need a long and standard spatula.

Scoop the mixture with a short spatula, evenly distribute it over a long one, and apply the putty with force on the wall with smoothing movements. After the solution has completely dried, sand the surface with sandpaper with a grit of 240 or 320. During grinding, dust is formed that must be removed with a vacuum cleaner, and in case of heavy dust, wipe the wall with a damp cloth. Be sure to prime the walls after sanding. Wallpaper can be glued onto a dry surface.

Wall preparation in a new building

Apartments in a new building can be rented out with plastered walls, or “in concrete”. In the first case, check the quality of the plaster. Tap the walls. Poor-quality mortar applied in violation of technology may crumble or crack. You need to get rid of such a finish - it will continue to collapse. When the strength of the plaster is beyond doubt, check the walls with a spirit level. If the walls are “littered”, they will have to be leveled with a plaster composition.

If the surface has passed the level test, take a two-meter rail, attach it to the wall in different directions. An error of 1-3 mm does not need alignment. Depressions and bulges within 5-7 mm will have to be puttied. Larger differences require plastering. If your apartment has concrete walls, then you can use it for additional insulation. The sequence of work remains the same: plastering, puttying, grinding. Priming is done after each stage.

Preparing walls before applying liquid wallpaper

Liquid wallpaper is a dry mixture of cellulose and silk fibers, decorative inclusions, pigment and glue. Before applying to the wall, dry components are diluted with water and applied to the wall with a spatula. Liquid wallpaper has a three-dimensional structure that will hide minor wall errors, but this is a rather expensive material, so pre-preparation of the walls will save money and allow you to get a high-quality coating.

Surface preparation is carried out by analogy with the preparation of walls for pasting with ordinary wallpaper, but has several features:

• Make sure that there are no nails, screws or other metal inclusions in the wall that can rust over time. Rust spots will show through the decorative layer, spoiling its appearance.
• Cover the leveled surface of the wall with 2-3 layers of light water-dispersion paint to avoid spotting the decorative layer.
• The concrete wall needs to be puttied with gypsum putty, it will give the wall an even white color and hide all the bumps. After the putty has dried, a primer is applied in two layers, then a water-dispersion paint in three layers.

Preparing walls for wallpapering is within the power of even inexperienced craftsmen.

Follow the instructions for the selected materials, follow the sequence of work and remember: an attempt to save time or money at the preparatory stage will result in the need for a complete redo of the repair.

Preparing the wall for wallpapering step by step instructions

Almost every person is sure that gluing wallpaper is quite simple and there is nothing complicated in this process. At first glance, wallpapering is really simple, but at the same time, the procedure has many important nuances and takes a lot of time and patience.

An incredibly important step during wallpapering is the proper preparation of the walls for the future procedure. This moment is generally considered to be the most important, because if it is done incorrectly, then soon enough you will need to think about a new repair and another wallpapering.

Before you prepare the walls for wallpapering, you need to know the main steps, because, otherwise, you will have to spend not only your money, but also a lot of time and your own strength one or more times. It is worth noting that, in fact, step-by-step instructions for preparing the walls and directly wallpapering the wallpaper are a simple process and anyone can handle it on their own. You just need to understand the technology and study it in detail, and the added video materials on our website will help you prepare the walls for wallpapering with your own hands in the shortest possible time.

Getting rid of old wallpaper

Before you prepare the walls for wallpapering, it is imperative to remove the previous finish from the walls, which can ruin all your work quite badly. In some situations, this step can be very difficult to complete, but you need to make every effort to remove the old finish. If you skip this stage of work, then there is no point in continuing it. In order to be able to remove the old wallpaper, you first need to make it as soft as possible.

If earlier there were ordinary paper wallpapers on the walls, then they must first be wetted with a special soapy solution. You can add a small amount of wallpaper glue to its composition so that the solution itself stays on the walls longer and can make the old wallpaper softer.

If you need to eliminate thick wallpaper or a washable type, then make cuts or at least scratches before applying the solution. This will allow the soap and water to get inside the wallpaper and do its job. When the wallpaper becomes soft, you can begin to remove it. To do this, use a regular metal spatula. If the first time it was not possible to completely eliminate the wallpaper, then repeat the procedure again. There will definitely be those places where the wallpaper will remain in place. To remove them, wet a cloth well and iron the wallpaper through this cloth.

Two-layer vinyl type wallpaper is quite difficult to remove. First, make horizontal cuts along the wallpaper, and then begin to gradually remove them, starting from the wallpaper layer that is at the top. You can not remove the paper layer and leave it as a basis for future new wallpapers, but with one condition: this layer must hold very well.

We clean the walls from old paint

Sometimes it becomes necessary to remove not a layer of wallpaper, but paint. If the layer is sufficiently dense, then a spatula can be used to remove it. If the layer is thin, then it is easier to remove it - you can simply wash it off. To do this, make a soap solution and wet the walls very well. If you do not complete this stage of work and leave the paint in place, then expect that after a short period of time, the new wallpaper will lag behind the walls along with the old layer of paint and the whole job will be done in vain.

If the walls were painted with enamel paint, then a special wash must be used to remove it. Apply this liquid to the walls with a brush and leave for a while so that it can completely soak into the old paint. Then you can start removing the paint, you can do this with a spatula. If the paint cannot be removed the first time, then you need to apply another layer of wash and wait a while. It should be noted that during this work you need to use rubber gloves, because the chemicals from the wash can damage the skin of the hands quite badly.

Do walls need to be primed before wallpapering?

Imagine that you have already finished making repairs, pasted beautiful and expensive wallpapers, finished finishing work. After a while, the brand new wallpaper begins to flake off. This will be the very first and fairly clear answer to whether the walls need to be primed before starting work.

Of course, you need to remember that even if you learn the main steps of the step-by-step instructions for preparing the walls for wallpapering and do everything right, this still does not give a full guarantee that the wallpaper will not peel off. In this matter, you must also take into account the quality of the glue, and how the wallpaper was pasted and a large number of other nuances.

Why prime the walls before wallpapering

There are several reasons why it is imperative to carry out the priming of the walls. The main reasons include the following:

How to prime the walls before wallpapering

This question is quite simple and the answer is the same. For priming, you need to use a special priming adhesive. To date, this material is considered to be quite primitive and is rarely used. Most often, the material for the primer is chosen depending on the type of surface on which you are going to glue the wallpaper.

Before starting the priming process, you need to carefully read the step-by-step instructions for preparing walls for wallpapering in order to understand how the material can be used. Experts often recommend using a special acrylic composition. This primer is made of latex and acrylic, which allows you to get the maximum level of adhesion. The material is applied in several stages, as a base and then, if necessary. This material is perfect as a basis for a wide variety of wallpapers.

If the walls are wooden, then you can use an alkyd primer. This material was created specifically in order to be able to glue wallpaper on a tree. One layer of this type of impregnation can dry for 15 hours.

Modern glyptal primers have also proven themselves well. This material is used both for processing wooden walls and metal ones. At the same time, one important point must be remembered: such a primer can only be applied in those rooms where the level of humidity is low.

How to prime the walls with your own hands video

In order to properly prepare the walls for wallpapering, do not skimp on the materials. Specialists can perform their work very efficiently, but poor-quality and inappropriate building and consumable materials can spoil the entire final result of the construction and repair work performed, including wallpapering.

How to putty the walls under the wallpaper

There are a few important rules to follow when priming walls before wallpapering. The material must be applied without fail only with a thin layer and the wall, and then smeared with a fairly wide spatula.

When the primer is completely dry, it is necessary to sand the walls. To do this, use a fine skin. As practice shows, in order to be able to glue the wallpaper - just one layer of putty is enough.

Preparing walls for wallpapering with your own hands step by step video

In some cases, when there are, for example, irregularities on the wall or other defects, several layers of primer must be applied. Sometimes it is enough to additionally apply a small amount of material in only one place.

What to do if the walls are completely crooked

Quite often you can find situations where the room has uneven walls. Then almost all finishing materials will not fit perfectly, which will lead to noticeable defects. Curved walls need to be prepared for wallpapering in exactly the same way as smooth ones. That's just to perform each stage of preparation must be more carefully.

Preparation of uneven walls: how to properly putty and primer walls video

When the preparatory work is completed, carefully inspect the room, you may have missed some section of the wall and did not remove the defect. This will make already crooked walls even more crooked and ugly. Accordingly, the result of the work may not be exactly what you expect to see.

Particular attention in this situation should be paid precisely to the choice of wallpaper. If the walls are very crooked, then it is better to buy vinyl wallpaper or non-woven. Due to their density, layering and embossing, they may well hide at least partially some defects. For these wallpapers, buy only special glue, this will allow you to do the job efficiently, and then the wallpaper will not move away from the walls. At the same time, experts recommend applying glue both to the walls and to the wallpaper in order to get the maximum positive result.

Due to the fact that the wallpaper must be glued end-to-end, use a level to glue the wallpaper of the first canvas. If the ceiling is uneven in the room, then do not panic. With the help of a ceiling plinth, it will be possible to some extent to hide these irregularities and other defects.

If uneven walls annoy you very much, then you can completely align them. There are several ways to do this, but each of them will reduce the size of the room to some extent.

Before you prepare the walls for wallpapering, carefully study all the steps before starting work, because this process is simple only at first glance.

If you do not follow the simple rules and the procedure for preparing the wall for wallpapering according to step-by-step instructions, then all your work will not bring any result and after a while you will need to repeat everything again. You will have to glue the wallpaper until you have done all the preparatory work correctly.

Preparing walls for wallpapering: do it yourself

Wall preparation for wallpaper

Preparing the walls for wallpapering is a job that determines the quality and duration of the coating. This stage of work can, if desired, be performed by any person without special training. The main thing is patience and the desire to get a good result. And how to do it yourself, the article will help.

Features of preparing surfaces for wallpaper

Tip: Despite the fact that many consider it right to re-paste wallpaper after 3 - 5 years, due to a change in their appearance, this is not entirely true. Expensive materials, when properly glued, last at least ten years or until they get bored.

The main requirements for walls when applying wallpaper are:

Tip: If the walls are not processed before wallpapering, in unprepared uneven places, over time, any materials begin to tear, deteriorate or wear out. This requires a smooth and clean wall. This rule should be observed on concrete bases in the hallway or plasterboard walls in a small children's room.

• Most wallpaper sheets are unable to hide even very small defects.
• A mandatory requirement for the surface is dryness, good cleanliness and impregnation of the wall with a primer.

The abbreviated instruction for preparing the walls looks like this:

How to remove old wallpaper

Cleaning walls from old wallpaper

Before preparing the walls for wallpapering, the old coating is removed.

To do this, you will need to purchase:

• Putty knife.
• Good quality roller.
• Liquid dispenser.
• Water and other aids that will ensure the quick removal of old canvases.
• A stepladder or a special construction bar for convenient and quick work in hard-to-reach places.

Advice: Before starting work, precautions should be taken: turn off the voltage in the power supply of the working room, put on overalls.

• In the areas where panels join, the quality of their adhesion to the wall is the lowest. It is from these places that you need to start tearing off the canvases, without the use of auxiliary means.
• Not removed parts of old wallpaper are abundantly wetted with a roller or sprayer with hot water.
• The surface is carefully cleaned with a spatula, everything that is easy to remove is removed from it.

Tip: To speed up the process of removing wallpaper, add vinegar or another adhesive solvent to the water. You can use special chemical compounds that are designed to remove previously pasted wallpaper from the walls. But their price is quite high and such a purchase is not always justified.

Before preparing the wall for wallpapering, the old canvases must be completely removed.

Removing the paint yourself from the wall is quite simple.

With minimal effort, this can be done in several ways:

• The paint is pre-dried using a building hair dryer, then it is easily removed with an ordinary spatula. The method is quite effective, but harmful. This requires constant circulation of fresh air in the room. Due to the heating of the paint, the release of toxic substances hazardous to health begins, they cannot be breathed for a long time.
• Walls can be cleaned with a grinder or grinder.

Tip: This method is very dusty, it should not be used by people who suffer from asthma. During work, all adjacent doors to other rooms should be tightly closed, and the windows should be left open.

• The use of a flush mixture is the most effective option. The disadvantage of this method is that when working with chemicals, you must carefully follow all precautions and carefully follow the advice of the manufacturer's instructions.

How to process the walls before wallpapering, everyone decides for themselves. After their cleaning, the suitability of the surface for gluing the material is controlled. After this stage is over, you can start priming the surface.

How to prime walls

Wall priming is performed in order to:

• To prevent the peeling of small particles of plaster or concrete, penetrating deep into the thickness of the wall and fasten its surface layer.
• The primer composition (see Types of building primers and their scope) increases the drying period of subsequent layers of putty, depriving the wall of the ability to quickly absorb moisture, which improves the quality of the coating.

Tip: With the rapid drying of any mortar, nothing good will come of it, the minimum defect is the formation of cracks on the surface.

• Applying a primer removes dust. Apply the solution with a large brush or brush. The composition should be rubbed into the surface, as it were, until a white foam is obtained.

The next step, how to prepare a wall for wallpapering, should be carried out after the final drying of the walls.

Material application procedure:

• The primer solution is applied to the entire surface with a roller, as shown in the photo, evenly. Hard-to-reach places should be treated with a brush.
• With the rapid absorption of the composition into the wall, several more layers are applied additionally.
• After the primer has dried, a rough leveling of the surface is performed.

How to repair potholes and cracks

Puttying the walls will hide cracks and potholes only superficially, and such defects can quickly appear again.

When filling cracks:

• They need to be increased to about one centimeter wide.
• Open these places with a primer.
• Seal everything with cement mortar or glue used for tiles, which is much better.

Cracks in plaster simply do not appear by themselves. This indicates that in this place the plaster began to lag behind the base of the wall. In this case, you will need to remove the falling plaster with a hammer.

Tip: When shedding old plaster in large pieces, a major overhaul will be needed, which involves leveling the walls with mortar a second time.

• After the areas have completely dried, they are primed with high quality and you can proceed to the next stage of surface preparation.

How to prepare the walls for wallpapering? The next step is to apply at least a small layer of putty. It is necessary to reduce surface roughness and increase the bonding area. Putty just smooths out all the bumps.

Tip: Finishing putty should be applied only in thin layers, otherwise large ones will crack when dry.

All irregularities are eliminated in several passes, sometimes up to five times, until the wall becomes even. After the solution dries, all defects are removed from the walls with an abrasive mesh: tubercles and sagging. Small protruding sagging after puttying can be removed with a spatula.

At the last stage of work, which involves preparing concrete walls for wallpaper, their primer is again applied.

Tip: When preparing walls for wallpapering, after each step, the surface should be primed.

Instructions for preparing walls for wallpapering

Before you start wallpapering, it is necessary to carry out preliminary preparation. Many people know that you need to pre-prepare the wall, but few people understand the real meaning of this. What should be the sequence of actions during the pre-treatment of walls for wallpaper? What are the subtleties in the preparatory process?

What qualities should a wall have so that the wallpaper sticks well and lasts a long time?

Preparing the walls for wallpapering is recognized by many as a very important point. Otherwise, after a few years, there will be a deterioration in the appearance of the finish and thoughts of a new repair will begin to come to mind. Plus, it is wrong to prepare the walls for wallpapering - this is not only additional financial resources, but also a waste of time and effort.

Grouting joints and puttying wall irregularities before wallpapering

In most cases, the wall can hardly be called an ideal surface for repairs: it has visible bumps, glue residue from past wallpapering, protruding fittings and additional flaws. What's left to do? For the result to be worthwhile, additional preparation of the wall surface should be carried out before gluing the wallpaper with your own hands. This will make it possible to make the surface perfectly flat and suitable for wallpapering.

Tools and materials

The process of preparing the walls does not require any special skills, but to bring them to an ideal state, you still cannot do without a building tool. It is not particularly varied, but is required. It includes:

• various types of spatulas necessary for removing the old coating and applying putty;
• a brush needed for applying glue and priming in places that are hard to reach for a roller;
• a sponge for wetting and smoothing, as well as a rubber roller for wallpapering;
• screwdrivers designed to dismantle all kinds of wall items, which may include wall shelves, lamps, sockets, etc.;
• a mount or nail puller necessary for removing skirting boards and other decorative elements;
• sandpaper, the purpose of which is to grind the surface;
• plastic and metal buckets, rags, rags.

Preliminary work

Preparing walls for wallpapering is much more difficult than, in itself, wall decoration: therefore, close attention is paid to wall repair. The main task is to ensure that the preparation of the wall surface is correct before you start gluing the wallpaper.

Dismantling of wall cabinets, baseboards, sockets, switches

Since the walls of a modern room are difficult to imagine completely empty: without electrical appliances, shelves, sockets, etc. then before carrying out work related to wallpapering, they must be completely freed from all unnecessary. First of all, you need to disconnect the room from the electricity supply, after which you need to check all the switches and sockets for a lack of power.

Advice: Remove protruding parts from sockets and switches, and to prevent moisture from getting into the slots, cover them, for example, with masking tape.

Removing old wallpapers

To remove the old coating, it must first be softened. Of great importance are the types of wallpaper that you plan to glue.

If there were paper wallpapers on the walls in the room, then it is enough to soften them with a soapy solution, to which you can add a small amount of wallpaper glue. This should be done so that the liquid becomes thicker and lingers on the surface of the wall. On washable wallpaper, it is desirable to make cuts so that the solution can penetrate to the base through a dense layer of material.

Wetting the wall with a roller to soak and easily remove old wallpaper.

After soaking, they must be removed using a metal spatula. If the old coating is not completely removed, then the procedure should be repeated. In places where cleaning is difficult, you can use an ordinary iron by ironing the difficult area through a damp cloth.

In the case of vinyl wallpaper, the process is a little more complicated. They need to make cuts, after which you can begin to remove the top layer of vinyl wallpaper. The bottom paper layer of vinyl wallpaper that remains can be used as a base for future wallpaper, but only if it is firmly held.

Removing old paint

Removing old paint during the repair process should not be difficult.

With minimal cost, this can be done in several ways:

• The paint, which is the main coating of the wall, is pre-dried using a standard building hair dryer, and then it is easily removed with an ordinary spatula. The method is effective, but at the same time harmful. This requires the presence in the repaired room of permanent circulation of fresh air. Due to the heating of the paint, toxic substances dangerous to human health are released, which are not recommended to be inhaled for a long time;
• To clean the surface, you can use a grinder or grinder.

Removing oil paint from the walls with a grinder and a nozzle in the form of a round metal brush.

If oil paint or enamel is applied to the surface, then it is worth using sandpaper to remove it. The water emulsion can be easily removed with a spatula, previously moistened with soapy water.

Removing crumbling plaster and whitewash

The layer of plaster after removing the wallpaper needs a special assessment. You should make sure that there are no serious cracks on the old plaster and that it does not crumble. In order to make sure the integrity of the plaster, the wall is tapped - if there are “voiced” places, it means that the plaster has moved away from the base, which means it is crumbling. Small lagging plaster layers are beaten off and sealed with new plaster. If the damage is on a large surface, then it is better to knock down the plaster completely and re-plaster it.

Whitewash is also washed off without any problems. It is removed with a regular sponge and hot water. The only thing you need is to change the water in the bucket more often.

The procedure for preparing the surface for wallpapering

The first stage involves applying a spray to the walls, which should have a thickness of 3-9 millimeters. Such a layer is similar in consistency to thick sour cream, it can fill all the roughness and irregularities, it seamlessly lies on the surface of the wall. Depending on the composition of the spray, the plaster may normally adhere to the wall, or fall off the surface after a while.

The second stage is priming and puttying the walls. The thickness of the primer layer is usually 5-6 millimeters, in case of special need, several layers of it are gradually applied to the wall.

Applying the first coat of plaster to the wall using a long rule.

The third stage consists in applying the last layer of plaster to the wall surface, the thickness of which is 2-4 millimeters. The meaning of such actions is the formation of a thin film on the surface of the soil, which after a while is carefully rubbed off.

The fourth stage involves the alignment procedure using sandpaper.

Crack repair

After the preparatory processes of rough finishing and the removal of old wallpaper, the most even surface of the walls should be achieved.

The crack repair process includes:

• increasing their width up to 1 cm;
• opening these places with a primer;
• sealing them with cement mortar or glue used for ordinary tiles.

Wall puttying

After that, they move on to puttying. With special care, it is necessary to putty those areas where metal fittings are visible in order to avoid the appearance of rust spots on the wallpaper in the future. It is worth knowing that it will be better to apply putty in two layers - one in a vertical one. and the other in a horizontal direction, this will get away from the visible stripes formed by the spatula. You can also apply special strokes diagonally - each new one will look like an overlap overlay.

In order for the putty to be applied as conveniently as possible and the coating to become better, it is recommended to use a spatula with a width of about 30-40 cm, and the holding angle with respect to the wall should be 25-30 degrees.

For puttying corners, an angled spatula is usually used, which makes it possible to quickly and easily process corner surfaces.

wall sanding

After the putty layer has dried, it is recommended to start grinding the walls, for which sandpaper or a sanding grid is used. To start the grinding procedure, you need to use a bar, on which a grinding mesh or sandpaper is attached using special clamps.

Finishing sanding the walls with sandpaper before priming.

It must be remembered that grinding is quite a dusty job, during which you should use various personal protective equipment against dust. It is best to grind from corner to corner. Grinding should be in the direction of left-right and up-down. In the place where the wall has become smooth, there is no need to grind more. This is due to the fact that with too much zeal during grinding, all the putty can be rubbed off. After making sure that part of the surface is polished, you can move on to another area.

Applying primer under wallpaper

The last step is to apply a primer to the walls under the wallpaper. The modern market offers a wide range of various primers. Primers are selected based on the condition of the walls and their characteristics. The following types of primers can be distinguished: acrylic, alkyd, mineral, deep penetration and with coloring pigments. Acrylic primer is the most common today. You can figure out which primer suits you best, acrylic or alkyd, by looking at the label, or by consulting the seller.

Applying a primer to the walls is not a particularly difficult task - even a novice amateur can do it. To apply the primer, you need to use a wide roller, brush or special sprayer. It is also possible to use a telescopic rod to which a roller or brush is attached. In this way, you can avoid the constant movement of the stepladder, as well as gain access to the primer walls in hard-to-reach places. The primer is produced in dry or diluted form. When buying a dry primer, you need to use the instructions that come with it.

One of the important stages of the repair is the preparation of the walls for wallpapering. The main measures are to remove the old canvas and treat surfaces. The quality of the finish coating depends on how correctly this work is done. In fact, this is not at all a complicated process, and each person is able to carry it out with his own hands, the main thing is to treat it with responsibility.

Removing old wallpapers - getting started

We present a step-by-step instruction according to which the order of work will be as follows. First, the previous finish is removed from the walls. If this is a new building, where wallpapering has not yet been carried out, then this stage can be skipped. Old sheets must be softened before removal, but since they are made from different materials, an individual approach will be required. To remove paper wallpaper, they are moistened with water from a spray bottle and, after waiting until they become soft, they begin to clean off.

Another thing is canvases with a non-woven surface that are resistant to moisture, so it will be difficult to get the desired result with ordinary wetting. But in order for water to penetrate into the substrate and soften it, small cuts are made over the entire surface and only then moistened. After waiting a while and taking a regular spatula, the wallpaper is removed without problems.

Vinyl coatings are removed in two stages. First, the top layer, made of polyvinyl chloride, and only then - the paper base. They do the same with washable wallpaper, but since they are resistant to moisture, it is also necessary to make notches and moisten the surface with water. A more efficient way is to use a steam generator, a steam iron. After steaming, the paper backing will easily come off.



Liquid wallpaper can be removed with an industrial electric hair dryer or manually by softening them with warm water. To speed up the process, it is recommended to add a little primer to the solution. It is somewhat more difficult to remove canvases from drywall. Compared to GKL sheets, concrete surfaces have poorer adhesion, so there are no problems with them. To remove old coatings, they are smeared with inexpensive wallpaper paste, diluted to a liquid state, like kefir, and, after waiting for them to swell, they are pryed with an ordinary spatula.

Otherwise, they act if it is necessary to remove several layers of canvases. Since the wallpaper dries quickly and in order to prevent excessive moisture of the plaster, each layer, soaked with warm water, is removed separately.

Removal of old paint - a new stage

Sometimes you have to remove not the wallpaper, but the paint. Before starting the preparatory work, the existing plaster layer is evaluated, the surface of which should not crumble, have cracks and crevices. Even if it looks flawless, it must be tapped with a hammer over the entire area. The detected "voiced" places signal the poor quality of the coating and that the plaster has lagged behind. In the presence of large damage, it is better to remove the old material to the concrete base.



When the paint is thick enough, they try to pry it off with a spatula, if not and it is applied in a thin layer, then you can try to wash it off. To do this, you should use a soap solution prepared on your own, but it is better to remove enamel from concrete with a special wash. The chemicals it contains can damage the skin of the hands, so you must take precautions and wear rubber gloves.



The wash is applied to the walls with a brush so that it is completely absorbed into the old paint, left for a while, and the already softened one is removed with a spatula or other tool with sharp edges. If problems arise during the work, and the paintwork cannot be removed the first time, the composition is reused.

Elimination of irregularities with plaster

The next stage is the plastering of the walls, but first they are checked for cracks, crevices and irregularities. Having identified problem areas, they begin to eliminate them, having previously treated them with antifungal and primer compounds. The latter are necessary to improve the adhesion of all finishing materials, regardless of their purpose.



Small differences are eliminated with plaster, for which:

• The first forming layer is applied by spraying with a solution with a thickness of less than 1 cm. The mixture should have a creamy consistency.
• Dry and, after applying an additional layer of plaster, everything is leveled. If necessary, process with a special grater or sandpaper.
• Apply the final layer. After drying, the surface will become absolutely smooth, and wallpapering can be carried out.

In difficult cases, the walls are leveled with drywall. Since the sheets are even, the first step is to seal the seams, for which they use a sickle mesh and a plaster mixture. Further, if it is necessary to remove small irregularities, the entire surface is trimmed and, after allowing it to dry, a primer is applied.



To exclude the appearance of rust on the wallpaper, the heads of self-tapping screws or nails, with which the sheets were attached to the structure, should be painted with enamel paint.

Leveling the walls with putty

After large differences have been eliminated with plaster, you can start puttying, but before starting work, you should make sure that the applied mortar has completely dried. This is easy to check if a piece of polyethylene is glued to the surface with tape. During the hardening process, the plaster will release moisture, which will settle on the film in the form of condensate. And its absence will tell you that the solution is completely dry. After that, to increase the adhesion of the finishing layers, a primer is applied and puttying is started.



Putty is a good tool for leveling walls and eliminating small irregularities. It is sold in the form of dry mixes that require additional preparation, or is already completely ready for use. It is applied to the wall with a spatula, creating a thin layer of no more than 2 mm. But if it is necessary to glue "heavy" wallpapers, then their number is adjusted to 2-3. After soaking each of them with a primer, leave to dry for a while. Finally, the surface is sanded with sandpaper.

Preparing the base for liquid wallpaper and photo wallpaper

All work for gluing liquid wallpaper is done in several stages, which include:

• Elimination of any contamination, since the remaining dirt can appear on the finished surface in the form of stains.
• Puttying irregularities with gypsum mixture.
• Applying primer, if necessary - twice.
• Painting. It is preferable to use white paint, since the dark base will show through the wallpaper.



Wall murals place high demands on surface preparation - it must be perfectly flat. Otherwise, all errors will appear in the figure, and the image itself will be distorted. Therefore, in the process of leveling the walls, special beacons are used. The rest of the steps are unchanged.

How to act in special cases?

In rooms such as the kitchen and bathroom, mold often appears on the walls. To prevent its formation, problem areas are treated with lime mortar, it can be prepared at the rate of 200 gr. bleach per liter of water. And before sticking wallpaper - add a little to the glue.

Separately, I would like to say about the microclimate in the bathroom, which is characterized by frequent temperature changes, high humidity, lack of daylight. For this reason, tiles and plastic panels are the main finishing materials for walls. But if you choose the right wallpaper and glue, which must be resistant to moisture, the room can be made cozy and stylish. In this case, all the work is easy to do with your own hands, which is very important if there is no experience in gluing ceramics.
