In order to get the expected result from gluing wallpaper, you must conscientiously treat the preparation of walls to this process. First of all, you need to remove the old wallpaper, dry wallpaper usually depart well from the walls, but if the pieces do not lag behind them can be moistened and then removed with a spatula; it is not easy to scrap paint from the walls, but exfoliating areas are necessarily removed. All hillocks and protrusions on the pasted surface need to be eliminated if the surface crumbles better in 1-3 layers so that later the wallpaper does not lag behind the walls.
