Wallpaper Removal: Tools, Techniques, and Wall Repair After

Identify What You Have

Strippable wallpaper: the whole sheet peels off in one piece when you pull from a corner. Most vinyl wallpapers installed after 2000 are strippable. Pull from a bottom corner at a low angle — if large sheets come off cleanly, you got lucky.

Peelable wallpaper: the top decorative layer peels off but leaves a paper backing on the wall. The backing needs to be soaked and scraped off separately. Very common in homes from the 1980s-90s.

Traditional pasted wallpaper: neither layer separates easily. The whole thing needs soaking and scraping. Oldest and most labor-intensive to remove. Common in pre-1980s homes.

Wallpaper over unprimed drywall: the worst case. The paper adhesive has bonded directly to the drywall paper face. Removing the wallpaper pulls the drywall paper with it, leaving a rough, damaged surface that needs extensive skim coating. Test a small section before committing.

Prep the Room

Remove all switch plates and outlet covers. Tape plastic over the outlets and switches to keep water out — you will be spraying and steaming near electrical boxes.

Lay drop cloths or plastic sheeting on the floor. Wallpaper paste and stripper solution make a slippery mess. Overlap the floor covering 6 inches up the baseboard.

Move furniture to the center of the room and cover it. Even with care, water and paste splatter further than expected.

Turn off the circuit breakers for the room if you plan to use a steamer near outlets. Water and 120V are a bad combination.

Score the Surface

A scoring tool (Paper Tiger is the common brand) punches small holes through the wallpaper surface without cutting into the drywall underneath. Roll it across the entire wall in overlapping passes.

The holes let water or stripper solution soak through to dissolve the adhesive behind the paper. Without scoring, vinyl and coated wallpapers repel water and you will stand there spraying a waterproof surface.

Do not press too hard or use a knife to score. Gouging the drywall creates divots you will need to fill later. Light pressure with the scoring tool creates enough perforations.

Removal Method 1: Chemical Stripper

Mix wallpaper stripper concentrate with hot water in a pump sprayer per the label ratio. DIF and Piranha are common brands. Spray a manageable section (one wall or a 4x8 area) and let it soak 5-15 minutes.

Start scraping from a seam or loosened corner with a wide (6-inch) putty knife or wallpaper scraper. Hold the blade at a low angle to avoid gouging. The paper should come off in strips with the paste attached.

If the paper resists, spray more solution and wait another 5 minutes. Rushing the soak time means harder scraping and more wall damage.

Fabric softener mixed with hot water (1 cup per gallon) works as a cheap alternative. The surfactants dissolve paste reasonably well.

Removal Method 2: Steamer

A wallpaper steamer uses a hot plate pressed against the wall to soften adhesive with steam. Rent one from a hardware store for about $30/day if you have more than one room to do.

Hold the steam plate against one section for 15-30 seconds, then move it to the adjacent section while scraping the softened area. Work in a pattern: steam, move, scrape, steam, move, scrape.

Steamers work faster than chemical strippers on heavy paper and multiple layers. The downsides: they are hot (burn risk), they saturate the drywall with moisture (do not over-steam one area), and they make the room uncomfortably humid.

Steamers are the better choice for plaster walls, which handle moisture better than drywall. For drywall, chemical strippers are gentler.

Cleaning the Walls After Removal

After all paper is off, paste residue remains on the wall. It looks shiny or slightly tacky when you run your hand across it. If you paint over paste residue, the paint peels within months.

Wash the walls with hot water and a sponge, wringing frequently into a bucket. For stubborn paste, spray more stripper solution and scrub with a nylon pad. Rinse with clean water.

Let the walls dry completely — at least 24-48 hours. Run a dehumidifier or fans if the room is humid from steaming.

Repairing the Wall for Paint

Inspect for gouges, torn drywall paper, and lifted seams at drywall joints. Apply joint compound with a wide knife — thin coats, feathering the edges. Two thin coats, sanded between, are better than one thick coat.

If large areas of drywall paper are torn, apply a coat of oil-based primer (like Kilz Original or Zinsser BIN) before skim coating. The primer seals the damaged paper and prevents the skim coat from bubbling.

Sand repaired areas with 150-grit sandpaper. Prime the entire wall with a quality latex primer before painting. The wall texture will never be perfectly smooth after wallpaper removal — the primer and paint fill minor imperfections.

Tools for Wallpaper Removal

Scoring tool (Paper Tiger). Pump sprayer for stripper solution. 6-inch broad knife or wallpaper scraper — a flexible blade works better than a stiff one for this task. Drop cloths and plastic sheeting. Bucket and sponges for paste cleanup.

For wall repair: 6-inch and 10-inch joint compound knives, premixed lightweight joint compound, 150-grit sandpaper or sanding sponge, oil-based primer for damaged areas.
