Repair is almost complete - it remains to paste a few strips of wallpaper and you can go to rest. But the next day we "meet" surprises - in some places, the wallpaper covered with bubbles, and at the junctures and did not want to get stuck. What could be the cause of the wallpaper peeling off?

non-woven wallpaper is peeled off Well, when the wallpaper is peeled off only at the joints and in some places. But it happens that the whole strip leaves the wall or the ceiling and has to be re-glued.
Why this happens
Wallpaper gluing is a process consisting of several operations that need to be performed sequentially. If you break even one requirement, it can lead to sad consequences.
When the wallpaper moves away from the wall, this may mean that the surface was poorly prepared. It is especially difficult to glue the wallpaper on a wall covered with calcareous whitewash. Such walls in "Stalinist" and "Khrushchev" - not uncommon. Prepare the surface for wallpapering the wallpaper with special care. Experts recommend completely remove lime from the wall and clean it well. In addition, if you do not primetovat wall or ceiling, then you should not expect a high-quality adhesion wallpaper.
In addition to surface preparation, surprises can be expected from glue. It can also be substandard. Therefore, before you buy glue, pay attention to the expiration date. If you decide to glue the wallpaper for the first time, it's better not to trust the ads, but to buy a proven tool.
And a few words about the glue - often the advice of neighbors can spoil all the work. In the 50's and 60's, it was popular to make glue from water and flour. Such glue was widely used for gluing wallpapers. Now the quality of the material has changed and such a "paste" does not cope with its task. Therefore, you should not listen to such advice - it is better to purchase high-quality glue that will be suitable for your type of wallpaper.
The main reasons for wallpaper peeling:
- Wall defect. In their own house or apartment in the course of time, the walls begin to deform. Even in a new building, this phenomenon can not be ruled out. Therefore, always check the walls for strength before starting work. How to do it: take a hammer or other tool and gently knock on the wall, you can use a screwdriver and "pick off" part of the plaster. If it lends itself to falling down, then your wall is considered problematic and it is necessary to strengthen it. If you find a crack, it can not be ignored - do not stop immediately, the wallpaper may fall off together with a part of the plaster. It is better to clean the wall, and deep cracks and chips be covered with cement mortar.
- The ground is prepared badly. This is the most common cause of wallpaper peeling off. Perhaps you are too lazy to remove completely old wallpaper or on the walls and the ceiling there are traces of the old whitewash, plaster or paint. Even when you are advised not to take an old whitewash and glue the wallpaper directly on it - you do not need to trust the words, all the same in some places there will be air bubbles or wallpaper will disappear altogether. And it also happens that wanting to finish repairs sooner - one important stage is skipped - work with a primer mix. She simply forgot to apply. Naturally, expect that the wallpaper is well adhered to the untreated surface, do not.
- Non-compliance with recommendations. It would seem that everything is done correctly, but the wallpaper will still fall off. The reason can be that between each stage of the technology of preparation of walls there must pass the time, so that after the plastering, puttying and priming each layer is well dried. If you paste the canvas on a damp surface, then the corners of wallpaper can go away. Also, do not ignore the recommendations on the packaging. Even if there is experience of repair work, you still need to thoroughly study the instructions on the packaging of glue and wallpaper. Rules of operation may vary.
- The adhesive is applied unevenly. This is a frequent violation when, according to the instructions, the glue must be applied to a wall or ceiling, and it is spread over the canvas. Or when there is no roller, the glue is applied with a brush and passes are obtained. It also happens that the adhesive was not allowed to soak up properly or was applied very little.
- The wallpaper dries very slowly or too fast. To prevent the wallpaper from peeling off, watch for moisture evaporation. It should not evaporate quickly. When experts say that you can not open windows and doors to prevent drafts, these tips need to be listened to. If the repair is carried out in the heat, then the windows facing the sunny side should be closed. Low temperature and high humidity in the room lead to the fact that the wallpaper will dry slowly and subsequently they will blister.
- Use of poor-quality materials. You did everything according to the rules, but the wallpaper is still peeled off? Perhaps the reason lies in the use of poor-quality materials? It is worth paying attention to the storage conditions and the shelf life of the building material. In order to avoid the purchase of poor-quality materials, it is better to buy them in building stores.
