Preparing papered walls
- If your walls are already papered, it’s advisable to strip the existing paper even if the old paper is holding well, because moisture in the new paste may cause the foundation layer to soften. (However, if there’s just one layer of old paper in place, you can experiment by applying a single panel and waiting a day to check results.)
- Many wallpapers are “strippable,” which means they can be removed with very little trouble. To see if the paper you want to remove is strippable, start at the top and pry up a seam edge with a utility knife.
- Tug gently and slowly on the lifted corner, pulling down at an angle, keeping both hands close to the lifting edge.
- If it comes off easily, peels in a long sheet and leaves no adhesive residue, then removing the old paper will be a simple one-step operation.
- Older papers, and the newer ones applied with standard wallpaper adhesive, will probably have to be soaked to soften the paste. Protect the floor with drop cloths before you start.
