If you decide to glue the ceiling with wallpaper, you need to carefully prepare the surface. First, you need to remove the old ceiling finish. The whitewash is easily washed off with water, and the paint layer is removed with a spatula. Then the ceiling needs to be leveled. To do this, you need to purchase a starting and finish putty in a construction store, as well as a primer. Only after the ceiling becomes perfectly even can you start pasting it with wallpaper.
