The plaster is most often one of the required types of finishing work during the construction of various buildings. Is it possible to glue wallpaper for plaster? It is possible, because it is the optimal basis for a durable clutch with her paper base wallpaper. However, there is plaster, which is an independent element of the interior design, for example, decorative plaster. It is not at all suitable for sticking wallpaper.

In any case, the surface of the walls has to be pre-prepared. From how qualitatively it is done, the strength and beauty of the room decor with wallpaper depends.
For work is necessary:
- plumb and level;
- measuring tape;
- knife and scissors;
- roller, brushes, paintopult;
- Water pulverizer;
- sandpaper;
- Sponges, pieces of fabric;
- Bucket for glue.
Pre-processing of walls
If you intend to replace the old wallpaper old, first need to be removed. Sometimes new stripes stick to the old ones. It is impossible to do it - sooner or later they will start flaking from the walls!
Conventional paper wallpapers are removed very simple: you should first moisten them with water (most convenient with the help of the pulverizer), and then, when they get married, consider the spatula. The remains of old wallpaper, irregularities are well removed by coarse sandpaper.
Required tools for shook wallpaper.
The walls liberated from old wallpapers need to rinse with water and give them to dry. Then they should conduct an "revision" of surfaces on the subject of roughness and cracks. They will have to eliminate. If the walls are attacked neatly, you can only shine light cracks with putty. Nails, screws should be pulled out or deeply drown their caps, and the pits formed also smeared with putty.
If the walls are uneven, then one shouting cracks could not do - they will have to align their starting putty. Especially if it is necessary to stick not ordinary paper, but natural or tissue wallpapers that require a perfectly smooth surface.

It happens, the walls are lined with dry plaster in the form of plasterboard sheets. It is necessary for a solution of gypsum to sharpen all the joints that are always between them. When its first layer is dry, pieces of gauze are glued to the joints and put off again. Then align the processed places with shallow sandpaper, seeking that the whole wall looks like a single whole. Before glue on a plaster plaster, a waterproofing coating should be applied to it.
It is extremely desirable to prophylact the walls from mold fungi, processing them with one of the effective antiseptics. This, for example, "xyolate", "Natura Antimar", "Titan Fungicide", "C-hydroex-p", "Mugel". A thin film formed after applying a solution securely protects the wallpaper from mold microorganisms.
Is it necessary to primer walls?
Is it possible to glue the wallpaper for plaster without primer? You can, but not need.
After all, this is a very important technological stage, since the primer enhances the adhesive property of plaster.
Wall primer scheme.
It is necessary to rejuvenate the surfaces twice: before applying putty and before glue wallpaper. It is not worth saving on it, because it is actually saving on the quality of repair.
On the projected surface, the glue is distributed to a more uniform layer, and the flow rate is less. The primer is especially needed if the walls are old, loose, and the plaster crepts. It is not required only on painted surfaces or coated with finish putty.
The primer should be chosen, given the conditions of the room: its humidity, average temperature, surface texture. Is it possible to glue wallpaper on the walls, primedly diluted with wobble glue, how often do it? It is possible, but it is still better to use the composition, especially for this purpose.
One of the best options is a white primer under the PUFAS wallpaper. It can be applied even on plasterboard and painted walls. It dries about 6-8 hours, but it is better to stick wallpaper after a day. The primers "moment", "Concentrate 1: 7 Strengthening", Knauf Tiefengrund, Ceresit Art 17 have proven well.

Because they are abandoned with great difficulty, it is necessary to wear appropriate workwear. Especially it is necessary to protect your hands and eyes - the primer splashes can cause skin irritation and mucous membranes.
The process of applying the primer is simple: a wide brush, a roller or a paintopult is evenly applied to the prepared plaster. I don't need to be afraid to be afraid - they should simply gently smear over the entire surface of the wall, starting with her top and moving down. Then let the primer dry well.
Quality of wallpaper glue
From the right choice largely depends the durability of your work. The glue brand must accurately match the type of wallpaper glued. If, for example, it is necessary to glue the wallpaper light, paper, then any composition based on methylcellulose is quite consistent. But heavy, volume wallpaper This composition will not keep - more durable glue based on PVA is needed.
It is possible to glue the wallpaper with special glue. It is characterized in that it provides a particularly strong clutch of wallpaper with plaster, and it is impossible to remove it, except for the solvent. Useful information from the manufacturer, as a rule, always contains an indication of which brand of glue should be used to glue its products.
Modern adhesives are produced in dry and after proper dilution of their water guarantee a solid adhesion of wallpaper with treated surfaces. So, after applying the primer, wait until the walls are dry completely, and you can safely begin to glue the wallpaper on the plaster, which is now prepared for all the rules (see video).
