Start by blurring the ceiling.

Start by blurring the ceiling. If you got a ceiling with whitewashing, moisten it with a sponge or a rag, then remove the old whitewash with a spatula, and again pass by a sponge. And so — as many times as it will be needed in order to completely destroy the entire old layer of whitewashing. The work is exhausting, heavy, but otherwise a new ceiling coating will lie poorly or will be bubble subsequently. And beauty, as you know, requires victims, even if it is the beauty of the ceiling. After cleaning the ceiling, tearing off old wallpapers will seem to you a light vacation. The technology is the same — abundant wetting with water, and work with a spatula.
