Initially, a starting layer is applied, the thickness of which is 6 millimeters. If the base is in poor condition, crumbling and covered with cracks, then the first layer should be reinforced with a special mesh, it is best that it be plastic. After the first layer dries, which will take about a day, you can start applying the second. Often about 3 layers are required for walls or ceilings. Puttying with a finishing layer should be carried out in such a way that the thickness is 2 millimeters.
