How to Remove Wallpaper

­Though most strippable wall coverings are characterized by smooth, plasticlike textures (including viny­l, fabric-backed vinyl, or fabric-backed paper), the only way to find out if a covering is really strippable is to try peeling it off the wall. Here's how:

Step 1: Pry the paper up in an inconspicuous corner at the top of a wall with the tip of a utility knife.

Step 2: Grasp the tip of the corner and, keeping it as close to the wall as possible, try to pull it down the surface of the wall. Pulling it toward you and away from the wall increases the likelihood of tearing it. If a covering is strippable, it should peel away from the wall when you apply steady, moderate pressure. If not, you're probably dealing with a nonstrippable paper tha­t you will have to soak, steam, or dry-strip off the wall. Do not soak or use steam-stripping methods on drywall, though. The moisture can soften the wall's kraft-paper surface and its gypsum core. Instead, use a dry-strip method.­

­With this technique, you make horizontal slits in the surface of the old wall covering with a utility knife, a razor blade, or a special tool called a paper stripper, available at wall covering stores. The slits, made eight or ten inches apart, allow warm, soapy water or a liquid paper remover to get behind the paper and soften the adhesive so you can pull or scrape the paper off plaster walls. You can apply either solution with a sponge or a spray bottle. Caution: If you spray on a liquid paper remover, use a painters' mask to keep from inhaling chemical vapors.

Step 1: Apply the water or the paper remover and let it soak in for a few minutes.

Step 2: Do the same thing on the next strip, then go back to the first and wet it again top to bottom.

Step 3: Use a 3 1/2-inch-wide wall scraper with a flexible blade to begin stripping. Slide the blade under the top edge of one of the horizontal slits and, holding it at about a 30-degree angle, push up on the wet paper. A scraper-width section should rip along the sides of the blade and wrinkle up above it as you push.

Step 4: Continue pushing as long as the paper comes off. If the strip of scraped paper breaks, resoak that area and start scraping at another slit. If, after repeated soaking and scraping attempts, the adhesive is clearly not yielding, you'll have to use another method.

On walls made of drywall, use a paper stripper to make the horizontal slits as before, but don't wet the paper. Just slowly scrape or peel it away from the wall.

­Many tool rental and wallpaper outlets rent electrical steamers to do-it-yourselfers. These appliances typically consist of an electrically heated water tank connected by a long hose to a steamer plate with a perforated face. Here's how they're used:

Step 1: Once the water is hot, hold the plate against the wall until you see the wall covering darken with moisture around the edges of the plate. Start on a single strip and work from the top down.

Step 2: After about half of the strip has been steamed, lift a top corner with a fingernail or a utility knife and attempt to peel the paper downward. If that doesn't work, resort to a wall scraper. You may have to steam the same areas two or three times to loosen older adhesive behind the paper.
