I have bought wallpaper from a garage sale. It doesn't have any glue on the back of it. I am planning on putting it up in the hallway. The hallway has paint on it already. What do I have to do with the walls? ( if anything other than wash them.) What do I use for the back of the paper? Its from Japan, this paper is not easy to rip. My husband says if I put it up now, later if I take it down it will pull the paint and wall board down with it. I have already used wallpaper so many times before (that had glue on the back.) that I never had a problem taking it down.
