Internal construction work takes a large amount of time. After the ceiling has been painted, you can immediately start painting walls. Initially, it is necessary to completely clean all the walls. Cleaning, as a rule, occurs after the ceiling painting. These are peculiar sprayes that fell on top to the floor. Such splashes are not always easy to remove. They are removed with a knife or scraper. If a layer of primer should be put on the surface of the wall, then the walls can be painted only after the walls are completely dry.
