If the wallpaper has a texture you don’t want to detect through the paint, the whole wall should be sanded until smooth, using either a palm or orbital sander. Some experts recommend using a thin layer of wallpaper seam adhesive to reattach these loose fragments.Īnother recommendation is to lift those areas with a thin putty knife, cutting the loose bits away and filling in with spackle to create a level surface, then sanding lightly when completely dry. Look for peeling edges or seams, as these are the weakest areas in terms of adhesion. Step 2: Repair any damages to the wallpaper Leave plenty of time for the walls to dry. Don’t soak the walls with the water or solution because that could soften the adhesive below the wallpaper and cause it to loosen or bubble.
