How do I remove wallpaper from the wall?
To remove wallpaper, score the surface, then spray with a solution of hot water and dish soap or a commercial stripper. Let it soak, then peel or scrape it off. Wash residue and let walls dry before priming or painting.
Removing wallpaper is a common home improvement task, often necessary before painting or applying new wall coverings. While it can seem daunting, with the right tools and techniques, you can successfully strip wallpaper yourself. The process generally involves scoring the wallpaper to allow a solution to penetrate, applying a stripping solution, and then scraping or peeling the wallpaper off. Patience is key, especially with older or stubborn wallpaper.
Before you begin, gather your supplies. You’ll need a scoring tool (like a paper tiger or a utility knife), a spray bottle, a solution for loosening the wallpaper (hot water with dish soap, vinegar, or a commercial wallpaper stripper), a putty knife or wallpaper scraper, rags or sponges, a bucket, and drop cloths to protect your floors and furniture. For very stubborn wallpaper, you might also need a steamer.
Prepare the room for wallpaper removal
Start by clearing the room as much as possible. Move furniture away from the walls or to the center of the room. Cover any remaining furniture and the floor with drop cloths. Make sure to cover electrical outlets and light switches with painter’s tape to prevent moisture damage. Turn off the power to the room at the breaker box for safety, especially if you’ll be working near electrical fixtures. Open windows for ventilation, as the solutions can have strong odors and the process can be dusty.
Score the wallpaper
Most wallpaper has a vinyl or washable coating that prevents water or stripper solutions from penetrating. You need to create tiny holes in this surface so the solution can reach the adhesive. Use a scoring tool like a PaperTiger or a similar spiked roller. Gently roll it over the entire surface of the wallpaper. Don’t press too hard, as you don’t want to gouge the drywall underneath. Focus on creating a uniform pattern of small perforations across all the wallpapered areas.
Apply the wallpaper stripper solution
Mix your chosen stripping solution. A common DIY solution is hot water mixed with a tablespoon or two of dish soap, or a 50/50 mix of hot water and white vinegar. For tougher jobs, commercial wallpaper strippers are available at most hardware stores. Fill your spray bottle with the solution. Generously spray a section of the wallpaper, starting from the top and working your way down. Don’t oversaturate the walls, but ensure the entire surface is damp.
Let the solution sit on the wallpaper for the time recommended by the product manufacturer, or about 10-15 minutes for DIY solutions. This allows the liquid to soak into the paper and break down the adhesive. You should see the wallpaper begin to bubble or loosen. Re-apply the solution to any areas that seem to be drying out before you start scraping.
Scrape and peel the wallpaper
Once the wallpaper has softened, use a putty knife or a dedicated wallpaper scraper to lift an edge. Work at a low angle to avoid damaging the drywall. Gently push the scraper under the edge of the wallpaper and peel or scrape it away from the wall. Work in manageable sections. If the wallpaper comes off in large strips, that’s ideal. If it’s coming off in small pieces, continue scraping. Stubborn areas may require a second application of the stripping solution or the use of a wallpaper steamer.
Use a wallpaper steamer for stubborn areas
For wallpaper that resists scoring and stripping solutions, a wallpaper steamer can be a lifesaver. Rent or purchase one from a home improvement store. Follow the manufacturer’s instructions carefully. Hold the steam plate against the wall for 15-30 seconds until the wallpaper softens. Then, immediately try to scrape it off. Be cautious not to hold the steamer in one spot for too long, as excessive heat and moisture can damage the drywall. Work in small sections and have a helper if possible to hold the steamer.
Clean the walls after removing wallpaper
After all the wallpaper is removed, you’ll likely have adhesive residue left on the walls. Mix a solution of hot water and a bit more dish soap or a specialized wall cleaner. Use a sponge or rag to wash down the walls thoroughly. Rinse the sponge frequently and change the water as needed to ensure you’re not just spreading the glue around. Pay attention to corners and edges. This step is crucial for ensuring a smooth surface for painting or applying new wallpaper. Let the walls dry completely, which may take 24 hours.
Inspect and repair the walls
Once the walls are dry, inspect them for any remaining adhesive, tears, or damage to the drywall. Fill any small holes or gouges with spackling compound. Lightly sand the patched areas smooth once they are dry, and wipe away the dust with a damp cloth. Any imperfections will be visible after painting, so take the time to ensure the surface is as smooth as possible. After repairs, you’re ready to prime and paint or apply new wall covering.
Common Mistakes During Wallpaper Removal
| Step/Tool | Typical Mistake | Consequence |
|---|---|---|
| Scoring Tool | Scoring too deeply | Damaged drywall, requiring extensive patching |
| Stripping Solution Application | Not letting the solution soak long enough | Wallpaper doesn’t loosen, requiring more scraping and effort |
| Scraping | Using a sharp tool at a steep angle | Gouging or tearing the drywall surface |
| Cleaning Residue | Not rinsing the walls thoroughly | Adhesive residue prevents paint or new wallpaper from adhering properly |
FAQ
Can I just paint over old wallpaper?
While it might seem like a shortcut, painting over wallpaper is generally not recommended. The adhesive can fail over time, causing the wallpaper to bubble or peel, and any seams or imperfections will show through the paint. It’s best to remove the wallpaper first for a smooth, lasting finish.
How long does it typically take to remove wallpaper?
The time it takes can vary greatly depending on the type of wallpaper, the adhesive used, and how it was applied. A single room can take anywhere from a few hours to a full day or more. Factors like the age of the wallpaper and whether it’s vinyl-coated or paper-backed also play a role.
What is the best solution for removing wallpaper?
For most standard wallpapers, a solution of hot water and dish soap or white vinegar is effective. For more stubborn adhesives or vinyl-coated papers, a commercial wallpaper stripper or a wallpaper steamer will likely be necessary. Always test a small, inconspicuous area first.
