After the plaster dries, sandpaper roughness cleaned in several stages – first rough, then all the more subtle, until a smooth surface. The next step is painting, which is conducted in 3-4 layers. At the same time causing each subsequent layer of paint is performed only after complete drying of the previous one. Thus, the significantly greater time work performance, and prior to the completion of finishing the ceiling can not proceed to any registration of the walls, nor to the laying of floor coverings. Like all of the surface, the ceiling needs periodic cleaning, and use waterproof paint makes opportunity to "walk" on it with a damp sponge.
However, such a "luxury" can afford to power once in six months, otherwise it can start peeling the coating. A few years later the surface will be painted again, and this means that once again will have to make furniture, and then wash the paint stains from windows, walls and floors. Even the use of plastic film does not protect the surface from paint or putty dust. Despite the fact that zapotolochnoe the space between the original ceiling and sheets of drywall can accommodate ducts climate systems or electrical wiring, it should be remembered that access to all of these communications will be hampered. And when need to replace their separate elements of the ceiling drywall have to redo that is re-pass all the stages: installation sheet, seam gluing, putty, scraping, priming, painting surface, plus the removal of old plasterboard. And finally, a very real situation that may occur as a residential home and in public buildings – flooding due to pipe breaks or leakage from the roof. Water rather quickly soaked plaster and out the front side of the ceiling, and predict, in this case the warp the surface, no one will be taken.
