When performing cosmetic repairs in some homes, especially old ones, there are certain problems when pasting walls with wallpaper. The main disadvantage is that the walls in such houses are whitewashed, and the removal of whitewash can be delayed for a sufficiently long period.
How to paste wallpaper on whitewashed walls
However, in most cases, you can do without additional manipulation - with the proper preparation of the whitened surface, the wallpaper will lie flat and will serve for a long time to the delight of residents.
In fact, the process of gluing wallpaper on whitewashing is not anything complicated. It is enough just to memorize a few simple rules and clearly adhere to the technology.
First you need to prepare the walls. First, remove the old wallpaper( if any) and conduct a thorough inspection of all surfaces that are supposed to be pasted. The point is that whitewash, which includes lime, has the property of cracking and crumbling over time. To protect yourself and your repair from undesirable consequences, you should clean the damaged areas and ground them. This will ensure the most dense adherence of wallpaper material to the surface of the wall and will prevent internal rubbing whitewash.

Next, you need to thoroughly polish all the working surfaces from the lumps and other irregularities in order to subsequently all these "nuances" do not appear on the wallpaper. However, if the coating is thick enough and textured, you can not carry out this operation so carefully.
Wall primer
After grinding the walls and ceiling, it is necessary to primer. Primer composition is better to choose high quality, since cheap solutions do not penetrate deep enough into the surface and do not provide a reliable strengthening of the base for wallpaper. After the entire drying of the soil layer on the walls, the procedure must be repeated. And as the third layer should be used diluted with water wallpaper paste. The above actions will allow to strengthen and, as it were, "tie" the old whitewash in order to avoid its detachment and in the future - the disappearance of wallpaper.

Of course, this option of gluing walls is accompanied by a certain risk. If the walls were whitewashed more than once, then it is almost impossible to determine the state of all the layers that exist in the eyes and touch. To check the "endurance" whitewash, you need to process and wallpaper a small area on the wall or ceiling. After a while it will be possible to understand how the surface coating behaves. If the result suits, you can continue to work, if not, it is better to remove the whitewash and re-process the walls - so the result will be better.
In case of a positive "reaction" of a test piece of wallpaper, it is necessary to proceed directly to the process of pasting walls and ceiling. A very important stage is the choice of glue. Currently, there is a huge selection of different wallpapers - from simple paper to fabric. In the first case, the requirements for glue are not so high - it should be qualitative. But when gluing the "heavy" wallpaper, on a non-woven and fabric basis, the glue must be chosen necessarily specialized, since it contains special substances that allow better coupling of bulky material to the wall surface. In the case of whitewashed walls, this moment is extremely important.
The technology of wallpaper gluing is quite simple. To start, the canvas should be cut into pieces, taking into account the height of the wall with the allowances on the baseboard, and the drawing. When gluing the whitewashed walls, it is necessary to glue both surfaces for better bonding of the material. The wallpaper is glued to the back, in the direction from the window opening to the door, and in the corners - overlap. Each glued panel should be ironed with a roller or a sponge to remove air bubbles and excess glue.
These are the basic subtleties you need to know when pastes whitewashed walls with wallpaper. In general, the process practically does not differ from the standard procedure and requires only certain skills.
