has anyone used paintable wallpaper ... especially has anyone put up paintable wallpaper over damaged walls? it's a very old house and the room hasn't been worked on in years ... the paper is literally curling away from the wall ... if i start peeling off the paper, some plaster comes with it. i thought i'd pull it all off, scrape and spackle and then apply the paintable wallpaper that is supposedly like drywall.
