The following methods are used to align the corners, walls:
-plastering angles
– preliminary grinding and plastering
-plastering walls with a perforated corner.
In the first method, a wide spatula is used. They evenly, along the entire surface of the corners, distribute the plaster, while taking 5-7 cm walls from each side. The spatula is brought to the corner, fill it with plaster and taken aside. When working with outer corners, 2-3 such procedures should be done.
The second method is used when leveling angles, the walls of which have an uneven tuberous surface.
For polishing, you can use sandpaper or grinding machine, depending on the condition of the walls. Remove all irregularities and tuberous surfaces from the corners, and then apply putty on the treated surface. Putty is applied in the same method as with the method of plastering angles.
When using the third method, before starting work on the wall, it is necessary to apply a layer of black putty. After the putty put in the corner, the perforated corner is pressed until the end. Then its position should be leveled.
Remove excess and equal the surface. After the angle dries, treat it with the starting and then finish putty.
