You can repair torn wallpaper yourself. Some tips:
Whenever you add wallpaper, keep a few extra pieces for touch-ups. Too often, manufacturers stop making your pattern, so you may not be able to buy what you need if yours rips later.
Let’s assume you have a two-inch tear in your wallpaper, and the edges fray and peel back so it looks like you have a moon crater in the middle of your wall. Using a wallpaper hanger’s razor-blade knife, cut an area twice the size of the tear. The reason: Cutting very small pieces of wallpaper is difficult and tedious, and forces you to use the blade too close to your fingers. Cutting out a bigger area gives you a more reasonable space to work in.
Next, carefully wet the area to loosen the dried wallpaper paste.Then, lift the square you cut out at one corner and peel it off. Continue to moisten it as needed to remove the wallpaper and paste.
Now, using your leftover wallpaper, cut a six-by-six-inch square, lining up the pattern so it matches the area of wallpaper you are repairing.
Place your patch on the wall, centered over the tear, and match the edges to the pattern on the wall as closely as possible.
Before you adhere it to the wall, clean the exposed sheetrock with a damp sponge. Don’t get too much water on the wall, though, as it can start to loosen the paste in the area surrounding the repair.
Once the drywall is clean and dry, apply your newly cut patch to the wall, matching patterns as closely as possible. Wipe excess moisture and paste off the wall and use apaper hanger’s roller to squeeze the paper joints together.###
