We do the right thing: how to apply shpaklevku to drywall
Work often begins( or reduces to this) with sealing joints. To do this you will need two spatulas - wide( 35 cm) and medium( 15 cm).It is often used grater and trowel, but with them you need to be prepared for the fact that the work will be delayed and not the fact that the result will be ideal.
All process technology is as follows:
- Type a thin putty putty, gently transfer it to the seam;
- Then take a wide spatula, and stretch the material as widely as possible;
- After several joints have been processed, it is possible to arm with only a wide spatula, this will save time, but you need a skill.

Main surfaces: how to putty plasterboard
Only after the starting layer has completely dried in the corners and joints, it is necessary to putty the main part of the plasterboard. First, the outer corners are strengthened by aluminum profiles. They are installed using a construction stapler and putty.
The material is applied to the wall and is spread out with a wide spatula. Move from top to bottom. If the room has arches or other complex structures, be sure to use a plastic corner. It is fixed with braces, and then shpaklyuetsya.
Work as fast as possible in order to be able to trim the adjacent trim strips in the process. After the putty is applied, allow the material to freeze.
It is worth saying that shpaklyuyut drywall sometimes and roller. This is done when you need to "whiten" a surface that has already been leveled to give it an even color for the subsequent work. But more often it is necessary to work as a platen.
Putty: finishing work
When the puttying is completed, do not rush with the subsequent finishing. The surface must dry thoroughly. Then all irregularities must be treated with small sandpaper. Be sure to do this in goggles and a respirator.
Then proceed as follows:
- Process the surface already with zero emery;
- Then apply a smooth primer layer;
- For the finishing use a special mixture, or the starting mixture dilute to the state of sour cream;
- Apply and stretch the material with a wide spatula - the putty layer must be thin and even;
- After the drying of this layer, it is necessary to again make the treatment with a primer, and only then you can glue the wallpaper or paint the wall.
With a surface treated in this way, you will easily remove the wallpaper on the next repair. Gypsum cardboard in this case, nothing is threatened. Ready to remodel is not worth it, even if there are small defects. Perhaps, it will be enough to grind or smooth out the finishing composition of a small area.
