Lining paper is used to create a flat surface base for applying wallpaper to your walls. Lining paper is most often waterproof and hides dents, scratches and tears in your drywall. Covering these blemishes with lining paper will provide you with a smooth no-hassle surface for your preferred wallpaper. Wallpaper has a tough time sticking to painted or oiled surfaces, so lining paper is used to create a plain material surface. Hang lining paper by applying wallpaper paste to the backside of the paper and pressing it against the wall.
Measure the height of your wall using a measuring tape. Use a utility knife to cut the lining paper into strips that measure the height of the wall.
Run a putty knife down the lining paper to form a tight, air-sealed bond. Hold the putty knife in your hand angling down and apply pressure to the putty knife as you run your hand vertically down the lining paper. Make sure all ends of the lining paper are bonded to the wall. Add a little wallpaper paste to any part of the lining paper that doesn't lie flat. Use the putty knife to flatten the paper, eliminating any air pockets.
