For reinforcementjoints, a sickle mesh or a special paper perforated tape is used. And, of course, the putty composition itself is needed, which can be purchased both ready-made and dry. It is recommended to purchase starting and finishing putty. It is best if they are released by the same manufacturer, as in this case maximum compatibility is achieved.
Select primer
Currently, a huge selection of primers is presented in construction stores, which greatly complicates the selection process. According to experts, water-based primers are considered the most optimal for drywall surfaces.
It is strictly forbidden to use an alkyd-based material for drywall primer, as it provokes deformation of the cardboard, which subsequently begins to bubble and delaminate.

Work in progress
Before sticking wallpaper on drywall, you need to properly arrange all the joints. First, they must be treated with a moisture-resistant deep penetration primer, and the areas are then thoroughly dried.
If it is not planned to reinforce the joints, then they can be treated with a high-strength composition and adhesion. Many experts in this field recommend using the Uniflot composition from Knauf.
In this case, it is necessary to putty the joints in several layers. The mixture must be applied carefully and evenly. After drying, polishing is carried out. In order to obtain a high-quality result, it is necessary to carry out all work with the exclusion of drafts. The most optimal temperature is considered to be above 15 degrees Celsius. If these recommendations are followed, the composition will dry quickly and will lie down perfectly.
With correctly and neatly puttied seams, on plasterboard surfaces, numerous problems will be avoided in the future.
Corners
Do I need to putty drywall under the wallpaper? Of course. Such work will help ensure the perfect end result. During the preparatory work, specialists for leveling parts of the wallsalso recommend using a corner for drywall. It has received huge demand due to its convenience and ease of use. With its help, without much difficulty, you can not only build perfectly even corners, but also ensure the protective function of parts of the walls.
Drywall corner can be purchased both straight and arched. During installation, it is not glued, but simply attached to the structure and fixed with putty or gypsum plaster. When used correctly, it will greatly facilitate the finishing of external and internal corners in the room.
As you can see, puttying plasterboard walls is a very important process that must be performed before wallpapering. The latter need to be glued only on a previously prepared surface.
