Get your tools and remove all wall switch plates, metal air vents, towel rods, toilet paper holders, etc. Take down any wall mounted light fixtures (turn power off a breaker first). To avoid losing the screws or having to keep track of them, screw them back in their respective locations after the plates and covers are removed.
Wallpaper has a difficult time sticking to dirty or greasy walls,so wipe down yours
with a damp cloth. Patch any holes in the walls, and give time for both your patches and water on the
walls to dry.
• If you are wallpapering over pre-painted walls,add a coat of primer first.
• If your walls have wallpaper already on them, take the time to remove it before adding your new layer of paper. This will guarantee a longer lasting application.
