Project step-by-step (6)
Protect the Floor and Woodwork
- Everything is going to get wet and sticky during this project, so carefully protect the floor, furniture and woodwork.
- Take everything off the walls, including vents, outlet covers and switch plates, and mask the openings with plastic and tape.
- Turn off the electricity to the room at the service panel and use high-quality work lamps on extension cords to light your work area.
- If possible, remove the furniture completely.
- If not, move it to the center of the room and cover it with plastic.
- Tape plastic to the baseboard, allowing it to overlap the floor about two feet.
- Pro tip: You'll want to protect the floors and prevent the water from running behind molding, baseboards and chair rails.
- Do this by creating a plastic "gutter" to catch it.
- Top the plastic gutter with more plastic and then cover that with towels.
- Press hard on the tape to create a watertight seal.
- Cover the draped plastic with more plastic and top that with towels to absorb the water as it runs down the walls.
- Pro tip: Replace them with dry towels as necessary.
Pull Off the Facing
- Do this step without using any water to begin the old wallpaper removal process.
- Pro tip: The point is to remove the top layer of paper and leave the backing on the wall.
- That way, the backing will easily soak up water, making the rest of the wallpaper removal faster and easier.
- Start at a corner near the ceiling or under a switch plate to begin. This is where the paper tends to be loose.
- Use a putty knife to get the edge of the paper started, if necessary, and pull the paper back slowly at a 45-degree angle, applying moderate pressure.
- You can sometimes pull down entire sheets of newer wallpapers with this technique.
- But the longer the paper has been up, the more likely it is to come off in smaller pieces (or not at all) as you try to peel off wallpaper.
- If you just can't remove the facing at all, use a scoring tool before moving on to the next step (see "Tough Tools for Tough Situations," below).
Soak Backing to Soften the Paste
- Apply the hottest water you can tolerate (wear gloves!) to the wallpaper backing and the remaining facing to soften them and the adhesive underneath.
- The hard part is doing this without damaging the wall surface.
- Plaster walls can take a lot of hot water without a problem.
- But drywall has a paper surface that can be damaged by prolonged contact with water.
- Pro tip: It's OK to moisten drywall, but don’t keep it wet for longer than 15 minutes at a time.
- Work in small sections so the backing doesn't dry out before you have a chance for wallpaper removal.
- Apply the water using a sponge (or a floor mop for the high spots).
- Pro tip: This lets you control the amount of water you're applying each time.
- Let the backing absorb the water for up to 15 minutes, until it starts to pull away from the wall.
- You may have to apply water several times to soften the paste.
- When the backing softens (use your fingernail or a scraper to check), you’re ready for the next step.
Scrape Off the Backing
- Use an old, really flexible metal spatula or putty knife with rounded corners to scrape the backing and remaining facing off the wall.
- Using a flexible blade is key because it won't dig into the drywall as much.
- Plastic spatulas or scrapers don't work — they're too thick to get underneath the backing.
- If you don't have a rounded putty knife, file the corners.
- Don't be too aggressive with the scraper. The drywall might be soft in spots and scraping too hard can easily gouge it.
Use Gel Stripper on Stubborn Paste
- This is the most important step, but the one that typically gets short shrift.
- There's going to be a lot of paste on the wall once the backing is gone, and it’s going to take a lot of effort to get it all off.
- Scrape off as much of the glue with a putty knife as you can.
- Then wash the walls thoroughly with a sponge and water.
- Paste has a dark sheen to it and the wall will still feel sticky.
- Pro tip: This is the moment when most people drop the ball. You're tired, the wall looks clean and you just want to be done. So the temptation is to call it a (very long) night and "not see" the paste that's still there.
- Spray a light mist of water on the "clean" wall.
- Hold your work light parallel to the wall and you'll see the paste that remains.
- If you don't get it all off, when you paint the wall, the paint will eventually flake and crackle. Wallpaper that's applied over it will bubble or fail to stick properly.
- Use a gel stripper to get the last bits of stubborn paste and backing off the wall.
- Pro tip: You won't need a whole lot, so it’s not going to break the bank.
- Spray any remaining paste and backing with gel stripper and let it sit for 15 to 20 minutes.
- Since the gel clings to the wall, you can scrape off the gel and the paste at the same time with minimal cleanup.
- After the paste is completely gone, rinse the wall with water until it's smooth and squeaky clean.
- Pro tip: Now go to bed.
Repair, Sand and Prime the Walls Smooth
- The next day after the wall has dried thoroughly, prep the wall for paint or new wallpaper.
- Patch large gouges or holes from the scoring tools with joint compound.
- If you have really banged-up walls over a large area, trowel on a 1/16-in.-thick skim coat of joint compound over the entire wall.
- Once your repairs are dry, sand the wall until it’s smooth.
- Sand the wall using a hand sander and 120-grit drywall sanding paper to smooth rough areas and remove any remaining backing or paste.
- If you plan to put up new wallpaper, use an acrylic primer that's formulated for wallpaper applications to make removing it easier the next time around.
- If you're going to paint, use a primer designed for that purpose.
- Pro tip: Always prime a wall, even if it's painted, before putting wallpaper on it. If you don't, you might remove the paper surface of the drywall when you try to remove it.
