Repair the walls. Here we act in the same way if they are painted. Warm the paint and carefully remove the spatula. If there are minor damage to the paint on the walls (cracked or moved away from the wall), they can be cleaned with a coarse -grained skin, then zero. It is important not to damage the plaster, otherwise you will have to putty and smooth. Before painting, you need to remove all the dust from the walls. So that the dust does not settle in other rooms, the doors must be curtained with a wet cloth. If there were wallpaper on the walls, they are abundantly wetted with water, and after a few minutes they will easily be removed with a spatula.
