How to get wallpaper off a wall
To get wallpaper off a wall, choose a method based on the wallpaper type: dry stripping, wetting with hot water and soap, or using a wallpaper steamer. Always score vinyl or coated papers first. Test your chosen method in an inconspicuous area to ensure it doesn’t damage the drywall beneath.
Getting wallpaper off a wall is a common home improvement task, especially when redecorating. The process can range from simple peeling to more involved steaming or chemical treatments. Your approach depends on the type of wallpaper, how it was applied, and the condition of your walls.
Before you begin, gather your supplies. You’ll likely need a scoring tool (like a paper tiger), a putty knife or scraper, a spray bottle, hot water, dish soap, a sponge or cloth, and possibly a wallpaper steamer or a commercial wallpaper remover solution. Drop cloths or old sheets are essential to protect your flooring and furniture.
Prepare the area for wallpaper removal
Clear the room of furniture as much as possible, or move it to the center and cover it with drop cloths. Protect your floors with plastic sheeting or canvas drop cloths, taping them securely along the baseboards. Turn off the power to outlets and light fixtures in the room to avoid electrical hazards, especially if you plan to use a steamer.
Remove any switch plates and outlet covers. Inspect the wallpaper. If it’s vinyl or vinyl-coated, you’ll likely need to score the surface to allow moisture to penetrate. If it’s a paper-based wallpaper, you might be able to start peeling from a corner or seam without scoring.
Score the wallpaper if necessary
For non-porous wallpapers like vinyl or foil, scoring is crucial. Use a wallpaper scoring tool (often called a paper tiger) to create tiny perforations across the entire surface. These holes allow the water or remover solution to penetrate the wallpaper and reach the adhesive underneath. Be careful not to press too hard, as you don’t want to damage the drywall beneath.
Work in sections, scoring about a 2-foot by 2-foot area at a time. This prevents the solution from drying out before you can remove it. Go over the wallpaper multiple times in different directions to ensure adequate perforation.
Apply hot water or a remover solution
Mix a solution of hot water and a few drops of dish soap in your spray bottle. Alternatively, you can use a commercial wallpaper remover solution according to the manufacturer’s instructions. Spray the solution generously onto the wallpaper, starting from the top and working your way down. Let the solution soak in for 10-15 minutes. You may need to reapply the solution if it dries out.
For very stubborn wallpaper, using a wallpaper steamer can be more effective. Follow the steamer’s instructions carefully. Hold the steam plate against the wall for about 30 seconds, moving it slowly across the surface. Be cautious not to over-steam any one area, as excessive moisture can damage drywall.
Scrape off the wallpaper
Once the wallpaper has softened, use a putty knife or a wide scraper to gently lift and remove the paper. Start at a seam or a corner. Hold the scraper at a low angle to avoid gouging the wall. Work in small sections, scraping away the loosened wallpaper. If the wallpaper comes off in large sheets, you’re doing it right.
If you encounter resistance, the wallpaper may not have soaked long enough, or the adhesive is particularly strong. Reapply the hot water or remover solution and let it sit longer before attempting to scrape again. For particularly sticky residue, you might need to use a specialized adhesive remover.
Clean off wallpaper paste residue
After removing all the wallpaper, you’ll likely have leftover paste residue on the walls. This needs to be thoroughly cleaned before you can prime or paint. Use a sponge or cloth dipped in hot, soapy water to scrub the walls. Rinse the sponge frequently and change the water as it becomes dirty.
For stubborn paste, a solution of warm water and white vinegar (equal parts) can be effective. You can also use a commercial wall cleaner designed for removing adhesive. Ensure you rinse the walls thoroughly with clean water to remove all traces of soap or cleaner, as any residue can interfere with primer and paint adhesion.
Prepare the walls for finishing
Once the walls are clean and dry, inspect them for any damage, such as gouges or holes. Fill any imperfections with spackling compound or joint compound. Allow the compound to dry completely, then sand it smooth. Feather the edges of the patched areas so they blend seamlessly with the rest of the wall.
Wipe down the walls with a damp cloth to remove any sanding dust. Allow the walls to dry completely. Now your walls are ready for priming and painting or applying new wallpaper. A smooth, clean surface is key to a professional-looking finish.
Common Mistakes During Wallpaper Removal
| Step/Tool | Typical Mistake |
|---|---|
| Scoring Tool | Not scoring porous wallpaper, or scoring too deep on vinyl. |
| Hot Water/Solution | Using cold water, or not allowing enough soaking time. |
| Scraper/Putty Knife | Holding the tool at too steep an angle, damaging the drywall. |
| Steamer | Holding the steamer in one place too long, causing water damage to drywall. |
FAQ
How to get wallpaper paste off walls
To remove wallpaper paste residue, use a sponge or cloth with hot, soapy water. Scrub the walls and rinse thoroughly with clean water. For tougher residue, a solution of equal parts warm water and white vinegar can be effective, or use a commercial wall cleaner designed for adhesive removal.
How do you get wallpaper glue off the wall
Wallpaper glue is best removed after the wallpaper is off. Apply a solution of hot water and dish soap, or a vinegar/water mix, and scrub gently with a sponge or cloth. Always rinse the wall clean with fresh water to ensure no adhesive remains, as this can affect new finishes.
What is the fastest way to remove wallpaper
The fastest method usually involves a wallpaper steamer. After scoring vinyl or non-porous papers, apply steam to loosen the adhesive. Scrape gently as the steam works. This method is effective for most wallpaper types, but always proceed with caution to avoid damaging the drywall.
Can I paint over old wallpaper
It’s generally not recommended to paint directly over old wallpaper. The seams may show through, and the paint may not adhere properly. Removing the wallpaper first ensures a smooth, professional finish for your new paint job.
