Stains Bleeding Through Wallpaper and Primer / Stain Blocker – Continuation to March 9 Post

Re my post from two days ago … I do think my fears were correct, and the mottled look was not part of the pattern , but was from discoloration from some substance in or under the wallpaper . Even after applying the BIN stain blocker , and my wallpaper primer Roman Pro 977 Ultra Prime , today I found a couple of specks like this, which had worked their way through . Some of them I spot-primed with KILZ , and some I just took a razor blade and cut out of the wall. If not treated or removed , stains like this can work their way through the surface of both paint and wallpaper . The paper I’m hanging today is black with a busy pattern, so you’ll never notice a 1/8″ speck of brown . But I still like to give my clients a pristine job . So was happy to apply the additional coat of stain blocker .
