Understanding the Challenges of Painted-Over Wallpaper
Why Painted Wallpaper Is Harder to Remove
The paint acts as a seal, preventing water or adhesive removers from penetrating the wallpaper effectively.
It often requires additional steps to soften the paint layer before tackling the wallpaper underneath.
The Importance of Preparation
Proper preparation can save you time and effort while protecting your walls and surrounding areas from unnecessary damage.
Tools and Materials You’ll Need
- Wallpaper scorer
- Utility knife
- Putty knife or scraper
- Spray bottle
- Hot water
- Wallpaper removal solution or white vinegar
- Steamer (optional)
- Drop cloths or plastic sheeting
- Sponge and clean rags
- Sandpaper
- Safety goggles and gloves
Step-by-Step Process to Remove Painted Wallpaper
Step 1: Prepare the Room
- Move furniture away from the walls and cover it with drop cloths or plastic sheeting.
- Protect your floors with additional drop cloths.
- Turn off electricity to the room and remove outlet covers and switch plates.
Step 2: Score the Wallpaper
- Use a wallpaper scorer to create small perforations in the paint and wallpaper layers.
- Work in sections, applying light pressure to avoid damaging the wall beneath.
- The more perforations you create, the easier it will be for the removal solution to penetrate.
Step 3: Apply a Wallpaper Removal Solution
- Fill a spray bottle with a mixture of hot water and wallpaper removal solution or white vinegar.
- Spray the solution generously onto the scored wallpaper, focusing on one section at a time.
- Allow the solution to sit for 10–15 minutes to soften the layers.
Step 4: Use a Steamer for Stubborn Areas
- If the wallpaper doesn’t loosen after applying the solution, consider using a wallpaper steamer.
- Hold the steamer against the wall for 10–15 seconds to loosen the adhesive.
- Test a small area before proceeding to ensure it won’t damage the wall.
Step 5: Scrape the Wallpaper
- Use a putty knife or scraper to gently lift and peel the wallpaper from the wall.
- Start at a seam or edge and work your way outward.
- Avoid gouging the wall by holding the scraper at a low angle.
Step 6: Repeat the Process for Remaining Sections
- Continue scoring, applying the solution, and scraping until all the wallpaper is removed.
- Reapply the solution or steam as needed for stubborn sections.
Step 7: Remove Residual Adhesive
- Use a sponge or cloth soaked in warm water to wipe away leftover adhesive.
- For tougher residues, mix equal parts vinegar and water and scrub gently with a sponge.
- Rinse the walls with clean water and dry thoroughly.
