Defects in Wallpaper

Problem: Wallpaper loosens at edges, becomes ripped, or creates bubbles.

Background: Even newer wall coverings, though much improved, can become damaged. Blisters in wallpaper can be fixed by lancing the wall paper with a razor blade or a craft knife to let the air out, then putting glue behind the loose paper and smoothening it with a wet sponge. Loose edges can simply be reglued with wallpaper adhesive. Rips and tears, however, require more work but can be repaired if the damaged area is not too large and you have extra wallpaper.

What to do: With ripped or torn wallpaper, you can often create an almost invisible patch. Find a section of extra wallpaper larger than the damaged area, and tape it over the damaged area, matching the pat tern. Using a razor blade, craft knife, or utility knife, cut straight lines (in the shape of a square, rectangle, tri angle) through both the new patch paper and the wallpaper on the wall. Next remove the top patch paper, as well as the paper on the wall, within the cut area. Coat the back of the patch with wallpaper adhesive, and fit it into the hole. Smoothen and wipe the patch with a damp sponge.

Special advice: If a bubble is next to an edge, you may be able to get rid of it by lifting the edge with a knife. Another way to flatten bubbles is to inject glue behind the bubbled paper with a needle-type injector which resembles a hypodermic needle. If wallpaper that isn’t washable be comes smudged, check a local wall paper store for special wallpaper dough or gum erasers to clean it with.

Helpful hint: Often extra leftover wallpaper, after a few years, will look newer and brighter than wall paper on the wall. To age patch material (so it will match), keep it exposed to similar conditions in an out-of-the-way place.
