The reason for the appearance of yellow spots on the ceiling may be a “flood”, arranged by neighbors from above in an apartment building, or the flow of a roof in the off -season in private buildings. Regardless of the reasons for their appearance, they spoil the appearance of the room as a whole and require measures to eliminate them.
Local elimination of yellow spots is not appropriate, since this will only spoil the ceiling surface. Therefore, the most optimal solution is the cosmetic repairs of the ceiling. For this, all things are taken out of the room. The remaining “unbearable” pieces of furniture are closed with plastic wrap. The old plaster is completely removed from the surface of the ceiling. The opened whitewash layer is moistened with a roller, and then cleaned with a metal brush. The next stage is started only after the surface dries.
If there are cracks on the ceiling, they are closed by means of acrylic plaster. To ensure better adhesion to finish, the ceiling is treated with a soil solution. As soon as the primer completely captures, the ceiling grinds. Repeated another layer of primer and the ceiling is covered with matte paint. After drying the paint, you can proceed to the final decoration of the ceiling – staining with acrylic or other paint.
