Re-sticking wallpaper is an important task because it prevents the wallpaper from continuing to peel. If you do not take the time to re-stick the wallpaper it can lead to ripping or tearing.

Dip your pasting brush into the overlap paste and brush in onto the section of the wallpaper that is peeling. This will wet the paper and make it sticky. Do not dampen it yourself; the glue will do that.
