You definitely need to say more about the wall(s), the paper, and the situation. (Do you want to save the wallpaper? Do you want to repair the wall w/o haveing to rip it out? And so on.) The bad news is I can't help you directly. BUT, if you don't get any help here, go to The Ornamental Plasterer WEB site and post the details there. (Tell Brian Ewing that Jay J sent ya!) The more you can say about the situation, the better.
