How to take wallpaper off a wall
To remove wallpaper, start by scoring the surface to allow a removal solution to penetrate. Apply a mixture of hot water and dish soap or a commercial stripper, let it soak, then peel and scrape the wallpaper away. Rinse and clean the wall afterward.
Removing wallpaper requires patience and the right approach. The process generally involves scoring the wallpaper, applying a stripping solution, and then scraping it off. You’ll need several tools and supplies to make the job manageable.
Gather your supplies: a scoring tool (like a paper tiger), a plastic putty knife or scraper, a spray bottle or garden sprayer, hot water, dish soap, a sponge, a bucket, and possibly a commercial wallpaper stripper. Drop cloths are essential to protect your floors and furniture.
Prepare the room for wallpaper removal
Before you start peeling, prepare the space. Turn off electricity to outlets and light switches in the room. Cover electrical boxes with painter’s tape. Lay drop cloths on the floor to catch falling debris and protect your flooring. Remove any furniture or move it to the center of the room and cover it with plastic sheeting.
Score the wallpaper
If the wallpaper is vinyl or has a protective coating, you must score it first. Use a scoring tool like a PaperRater or a similar spiked roller. Gently roll it over the entire surface of the wallpaper. This creates tiny holes that allow the stripping solution to penetrate the paper and adhesive.
Be careful not to press too hard, as you don’t want to gouge the drywall underneath. The goal is to perforate the wallpaper’s surface, not damage the wall structure.
Apply a wallpaper stripping solution
You have several options for a stripping solution. A simple and effective mixture is hot water with a few drops of dish soap. For tougher adhesives, a commercial wallpaper stripper can be more potent. Follow the manufacturer’s instructions if using a commercial product.
Fill a spray bottle or garden sprayer with your chosen solution. Generously spray the wallpaper, working in small sections. Allow the solution to soak into the paper for about 10-15 minutes. You should see the paper begin to bubble or soften.
Scrape and peel the wallpaper
Once the solution has had time to work, begin scraping. Use a plastic putty knife or a wallpaper scraper. Start at a seam or a corner and gently push the scraper under the wallpaper. Pull down at an angle to remove large sections at a time. If the wallpaper isn’t coming off easily, apply more solution and let it soak longer.
Address stubborn wallpaper adhesive
After removing the wallpaper layers, you might still have adhesive residue on the wall. This needs to be removed before painting or applying new wallpaper. You can use a sponge and warm water with a bit of dish soap, or a dedicated adhesive remover. Scrub the walls gently to remove all traces of the old glue.
Rinse the walls thoroughly with clean water and a sponge to remove any remaining cleaning solution or adhesive. Allow the walls to dry completely.
Repair and prepare the wall for finishing
Inspect the walls for any damage, such as gouges or small holes, that may have occurred during the removal process. Fill these with spackling compound and sand smooth once dry. Prime the walls before painting or applying new wallpaper. This seals the surface and ensures a better finish.

FAQ
Can I remove wallpaper without scoring?
Yes, if the wallpaper is strippable and does not have a vinyl or foil coating, you might be able to peel it off without scoring. However, scoring helps the stripping solution penetrate and makes removal easier for most types of wallpaper.
How long does wallpaper stripper need to soak?
Typically, wallpaper stripper needs to soak for 10 to 20 minutes. Always refer to the specific product’s instructions, as soaking times can vary. The goal is for the paper to soften significantly.
What’s the best way to remove old, stubborn wallpaper glue?
For stubborn adhesive, use a dedicated wallpaper adhesive remover. You may need to apply it, let it sit for a specified time, and then scrub with a sponge or scrub brush. Thorough rinsing is crucial afterward.
How do I know if I’ve removed all the adhesive?
After rinsing, run your hand over the wall. If it feels smooth and clean, you’ve likely removed most of the adhesive. If it feels sticky or rough, you’ll need to clean and rinse again.
