Wallpapers are used to cover the wall or ceilings of rooms and hallways. They are durable, and cost effective. When wallpaper has been hung properly it can last three times longer than paint. If you have imperfect walls, high quality wallpaper can hide surface imperfections. Wallpapers can also be, if desired, easily removed, and then, on the same surface, you can paste other wallpaper or paint it.
