What you need to do before wallpapering? Than to process walls before поклейкой? Preparing walls for gluing

Many people pay great attention to the process of choosing wallpaper, while not paying attention to the correct preparation of the surface before gluing them. And completely in vain. Preparing walls for pasting is an extremely important procedure, on which the success of an undertaking depends wholly and completely. And if it is illiterate or completely skipped this stage, then the new decorative coating, even if paid for it with a lot of money, will have a very unsightly appearance. Or do not hang on the wall at all, which, in principle, is even worse. Be that as it may, the preparation procedure must be carried out very carefully. About what, in fact, we want to tell those who do not know what to do before wallpapering, than to process the walls and why do it at all.

What should be the surface for wallpaper

So, what kind of preparatory work should be done before wallpapering, than to process the walls, so that the updated decor of the room not only pleased with the appearance, but also stayed high on the wall for a long time? In order to properly understand the essence of the matter and correctly determine the scope and type of finishing works, it is necessary to build on the opposite. That is, to know what the ideal surface should be for the wallpaper.

And it should be dry first. The wet surface will poorly absorb the water contained in the glue, and therefore the composition will not grasp on the wall properly and will not provide the required quality of adhesion of the surface with the decorative coating.

The substrate must be strong. That is, the presence of flaking surfaces on the wall, plastering areas literally breathing at hand, hanging old wallpaper and other unnecessary elements, is a direct contraindication to pasting. First, the base coat should, as they say, bring to mind, and only then proceed to the procedure of pasting.

The surface must be clean. If there are black stains from mold and fungus on it, the question of whether it is necessary to treat the walls before wallpapering, to ask at all meaningless. Here we are not even talking about how a new coating will look on such a wall, but how you will feel in the near future, because the dampness in the room and the fungus on the walls adversely affect not only the condition of the wallpaper, but also On your health.

The wall should be smooth and have a uniform color. Only then, on the new decorative coating, all possible and impossible defects will not appear, which will not cause joy from the work done, but bewilderment and vexation.

What is the preparation of walls in an ideal

Not always home-based craftsmen do thorough preparation. And quite often not because they do not know how to process the walls before wallpapering, but for the reason that this procedure itself is quite long and expensive. After all, ideally, the walls need to get rid of the old coating, then carry out antiseptic treatment of the substrate, then carefully level it with plaster, and then putty, peel and prime. There are a lot of works, and it will take a lot of expensive materials. Here are the craftsmen for all sorts of tricks, trying to skip this or that stage of preparation. Sometimes this can be done when there are appropriate prerequisites (we will give some cunning advice on this at the end of the article), but most often it is unwise to do so. In principle, of course, everyone decides for himself what he needs. One thing is also satisfied by the fact that a month after the repair the wallpaper hangs in the corners of the room and angrily cower with the seams that have parted, and the other starts almost a nervous attack at the sight of a small bump, protruding from under the wallpaper in a far from the most prominent place of the room.

We, in turn, still allow ourselves to give several recommendations and try to describe in as much detail and step by step how to properly work the walls before wallpapering.

Stage one: general preparation

This is a total cleaning of the wall covering from old wallpaper, paint, whitewash and other coatings that are on it. And also all sorts of "decorative" additions in the form of slender rows of hammered nails, various dowels, hooks and other unnecessary "jewelry." In general, in the end, you must have an absolutely clean, if it can be called so, wall.

Advice from professionals

If the old wallpaper is kept very firmly, do not try to tear them off with a layer of plaster. So you only damage an already fragile basis. Armed with a bucket of hot water and a brush. And moisten every ten minutes the area to be treated. Wallpaper soaked in water and begin to bubble and well behind the wall. If you want to remove vinyl wallpaper, first tear off the top layer from the coating, under which remains the paper base. Also remove it, before wetting with water.

As for oil paint, then it should be disposed of with a drill with a special nozzle. The whitewash is removed with a spatula, carefully carefully moistened the wall with water.

What to do with mold areas

So, you finally got rid of the old cover. But under it were found intricate drawings of black color and of unknown origin. It's mold. And you must definitely get rid of it. Everyone understands that it is necessary to take some special steps before gluing the wallpaper. Than to process walls in that case? Are there any special tools for this or simply clean the surface of black stains? Of course not. It is necessary or to acquire a special composition in the store, or to try to somehow manage the improvised means.

Arms against fungus

So, you've found mold under the old coating, and now you do not know what to do before wallpapering. Than to process walls that this attack again did not arise under already new decorative covering? Go to the building materials store and buy a special antibacterial primer of deep penetration. The most effective is the composition of "Ceresite". And diligently treat them with contaminated surfaces, previously washed off with a wet cloth ragged black. If the soil is not bought for some reason, you will have to use popular recipes. Dilute a glass of bleach in a liter of water . And diligently miss the areas infected with the fungus. You can do even trickier. Acquire a penny, but so beloved by many housewives solution for whitening under the name "Whiteness". In which there is so much chlorine mentioned above, that with the composition there is no comparable self-prepared remedy for mold.

How to treat concrete walls before wallpapering

The fungus seemed to be sorted out. And what if the old wallpaper suddenly revealed not a layer of plaster, but literally bare concrete? How to be in this case? To glue on such a foundation, modern wallpaper is by no means impossible. In general, this can be understood at a glance. This wall has a very unsightly appearance, it is all rough, in defects and literally causes tears with its curvature. Than to process walls before poklejkoj of wall-papers in that case? We answer - nothing! You just need to spit on the notorious savings and lost time and start plastering the surface. That, in fact, is the second stage in the process of competent preparation of the basis for wallpaper.

Plastering

As for the actual plastering process itself, there are two possible variants of the development of events. In the case of the concrete walls mentioned above (as well as brick walls or made of silicate blocks), there is no alternative. Plastering will have the entire surface, from corner to corner. And, in the case of a large curvature, certainly with the installation of beacons. By the way, you will have to perform the same procedure in the presence of plastered, but also very uneven surface. But if the wall does not cause any particular complaints, but only has small defects and the areas of curvature on it are relatively small, then it is possible to limit oneself to resuscitation measures. That is, to repair all existing defects and cracks in the plaster, as well as to straighten some areas. After that you need to wait for the drying of the solution, and then primratovat entire surface of the walls with an acrylic primer. After it has dried, you can proceed to the last step.

Puttying

The purpose of this procedure is to make the base base white and smooth. After that, you can glue any, even the most capricious wallpaper, without fear for the outcome of the case. As for the process itself, it's special for those who know how to hold a spatula, will not cause. You get a putty mixture, not necessarily very expensive, mix it up, apply a thin first layer on the walls, wait for the drying. Then clean it with sandpaper, primer, then shpaklyuete again, again clean and primer. In this case, it is not necessary that the surface is perfectly smooth, without a single scratch. Minor minor defects will disappear under the wallpaper. The main thing is to make it even and solid. But to reach the latter, and applied a primer. About it - a little more.

Which primer to treat the walls before wallpapering

Someone will not find the issue worth attention. Primer - and a primer. Bought - anointed - ready. But things are a bit more complicated. The fact is that at the moment there are quite a lot of all kinds of compositions. And not all of them fit the wallpaper, because they have a special purpose. Primer is designed to give the surface quality, such as adhesion. That is, it should maximally ensure adherence of wallpaper, their adhesion to the wall. And for these purposes is best suited acrylic primer. It is generally considered universal, compatible with all kinds of surfaces, and even dries quickly. So when buying a soil should not be tricky. Buy acrylic - just do not go wrong. The choice in the market is quite large, but the most popular brands are "Ceresite", "Snowball" and "Master".

And remember: after priming, the wall should dry well. And the best thing is not to rush and give her this day. And then you can proceed directly to the process of pasting.

It is compliance with all the above rules and carrying out the described procedures and will be the answer to the question of how to properly process the walls before wallpapering. This is the only way to get a really smooth and solid foundation. And glued to it wallpaper will be great to stay on the wall, pleasing you for many years with its excellent appearance.
