Wallpaper is a decorative way to cover interior walls but it can become outdated. Removing hung wallpaper allows you to redecorate an area to create an entirely new look. The proper way to remove wallpaper results in bare walls that require little preparation before being able to be painted or repapered.
You will need:
• Enzyme-based or liquid wallpaper remover
• Wallpaper-scarifying tool or coarse sandpaper
• Hand-pump garden sprayer (optional)
• Wallpaper steamer (optional)
• Putty knife or broad knife
• Ammonia or TSP
• Wall primer-sealer
Step 1: Strippable wallpaper is the most easily removed. Begin at a seam, gently pulling both the vinyl coated surface and the backing from the wall.
Step 2: The top layer of peelable wallpaper will easily peel off from the wall. However, a thin layer of adhesive and paper will remain. Use an enzyme-based wallpaper remover or a sponge moistened with water to remove this residue.
Step 3: If the paper cannot be stripped or peeled, a different approach is required. If the paper has a foil or vinyl covering, use a wallpaper-scarifying tool or coarse sandpaper to score the surface.
Step 4: Use an enzyme-based or liquid wallpaper remover to penetrate the surface and help decompose the adhesive.
Step 5: A wallpaper steamer is an alternative- it can be used to steam off scored wallpaper. However, a steamer can harm old or damaged walls or those made from very porous plaster. Therefore, this device should be tested in an inconspicuous spot before being used on the entire wall.
Step 6: Another option is to fill a garden sprayer with a combination of wallpaper remover and water, then use it to mist the wallpaper. However, this can be a messy process due to the amount of moisture.
Step 7: Once the wallpaper is in a removable state, begin at the top of the wall and work downward, removing all adhesive and paper with a wide putty knife or broad knife. Work carefully so you do not damage the wallboard. If the wall features multiple layers of wallpaper, follow Steps 3 and 4 (or the alternatives) to remove one layer at a time.
Step 8: Once all the adhesive and wallpaper have been removed, repair any damaged areas on the wall.
Step 9: Use an ammonia and water solution or TSP to wash the wall.
Step 10: Once the wall has dried, apply wall primer-sealer.
