The backsplash of a kitchen can be matched and extended to the entire kitchen wall with a wall skin. Some wall skins are three dimensionally textured to help give the kitchen a natural rock look, but those must be painted and plastered to complete the look. Wall skin can also refer to the vinyl stickers used to decorate a wall with images. Underneath the wall skin in most kitchens will still be a type of dry wall or rock board to meet all the appropriate fire safety standards.
