Necessary preparation of drywall for wallpapering
In some repair manuals you can find the statement that you only need to seal the joints after installing the GCR, and the gypsum board can be covered with wallpaper. Do not argue - this is so. And we will tell more - it is possible to not even ground a drywall, finishing material and without additional impregnation will lay down, that is called - tightly. However, in the future some troubles loom. Firstly, if you use light wallpapers, there is a high probability that the drywall will shine through. Secondly, if you want to change the design in the future( and sooner or later such a desire will appear), then the old wallpaper can only be torn off the wall together with the top layer of the GK-sheet - cardboard and thus you will destroy the wall. Therefore, we do not recommend going on about the immediate advantage, but doing everything according to the rules.
1. After completing the installation of the GCR, the whole area of the walls should be primed with a common brush or antifungal primer( if there is a high humidity in the room) with a wide brush.
2. For all joints, including in the corners, apply a sickle. It is such mesh material in rolls, similar to a bandage. The material is self-adhesive, but it is better to put it on PVA.
3. Joints, and at the same time the entire surface of the sheets of HA, must be carefully ground with a thin layer of starting putty, and after drying - with a finishing coat.
4. Possible irregularities should be gently ground with a special mesh or emery paper with a fine abrasive - grade 80 or 100. But do not be too zealous to prevent the gypsum card from radiating through. If this happens, you need to put it back together again.
5. After the puttying, before the drywall is covered with wallpaper, to remove all the dust from the walls and ensure a good adhesion, it is necessary to treat everything again with a primer. Instead, you can use wallpaper paste, the instructions for the use of which it is necessary to specify in what proportion to dilute for the primer. If, for some reason, this stage is impossible to perform, you need at least wipe all the walls with a damp cloth or sponge, "tying" dust particles.

Because GKL have a perfectly flat surface, and it is enough to glue the first strip correctly, and then - only to combine the joints and, naturally, the drawing, if it exists.
