I've started stripping the wallpaper from our bedroom and our intention is to paint straight onto the plaster underneath. The paper is coming off easily enough using a steam stripper but there is still a patchy white residue left on the wall which I'm guessing is the dried adhesive. Am I going to have to scrape all this off as well (which will take forever) or will I get away with running a 1/3 sheet sander over the walls to smooth before I paint.
Thanks
Jim
