You need to start whitewing with preliminary preparation. After all, the finish should be applied only to a clean, leveled ceiling. Otherwise, you will have to redo everything in a year, or even less. The whitewash will just fall off. Preparation begins with erosion of the ceiling. This process occurs using ordinary water from a crane, roller and rags. In order to avoid damage to property, all the furniture in the room should be covered with cellophane bags. After the ceiling is blurred, they start the next stage. The ceiling is examined and covered with mastic or putty all existing cracks and bumps. It will not be superfluous to learn more about the construction of a turnkey bath after repair.
After that, you need to wait until the putty or mastic dries, and start the primer primer. For this purpose, special compositions are sold in construction stores designed for ceilings. Further, so that the new layer of whitewashing is smooth, you should wait until the primer dries and start the main job. Whitewashing is applied with a special spray or using a spray gun. Do not rush – you need to apply a layer by a layer with a flat composition. After that, let the ceiling dry for several days. At this time, it is by no means allowed to touch him.
