Before preparing the walls, you need to prepare the room itself. To do this, take out all the furniture so that it does not interfere during repair work or cover with newspapers and fix it with a masking tape. Cover the floor with newspapers.
It is best to soak the old wallpapers using a sponge so that they can easily lag behind the walls, using a spatula and remember that even small pieces cannot be left so that there are no problems when laying new wallpaper.
