It takes industrial strength scratching to break the seal to allow water in through the 9 layers of paint. Then if you are lucky the odd strip of the top layer might come off. The little bastard bits of wood come off next (and go anywhere they bloody well like) and then finally the last lovely bit of paper actually absorbs some water and gives up hanging on for dear life. Our children will never experience this because we don't put the god awful stuff up and more.
Aibu to say that stripping wood chip wallpaper is the worst DIY decorating job?
Excellent job avoidance by me though, starting a MN thread
