How to Remove Wallpaper

Updated August 2026 · Home Project Resources

Identify what you are dealing with before you buy a single tool. Strippable, peelable, and traditional papers come off three completely different ways, and the wall behind them is either drywall or plaster, which changes the whole approach. Test one corner, learn those two facts, and the rest of the job picks itself.

Get that backwards and a cosmetic weekend turns into a drywall repair. Soaking a paper that would have peeled off dry is wasted effort. Soaking drywall that was never sealed is worse, because the paper facing swells, tears, and takes chunks of the wall with it.

How to remove wallpaper: the whole job in order

1. Test a corner to find out whether the paper is strippable, peelable, or traditional.
2. Identify the wall underneath as drywall or plaster.
3. Prep the room, meaning power off, floor protected, trim taped.
4. Pick a method from the table below based on those two answers.
5. Remove the face paper, working top down in manageable sections.
6. Remove the adhesive, which is a separate job people always skip.
7. Run the water test to prove the glue is truly gone.
8. Repair any torn wall face, then seal it.
9. Prime with a sealing primer before any paint touches it.

Steps 6 through 9 are where most failed wallpaper jobs actually fail. The paper comes off in an afternoon. The glue and the repair are the real work.

Step 1: the corner test

Pick an inconspicuous corner, behind a door or low near the baseboard. Slide a putty knife or a fingernail under the edge and lift about two inches, then pull steadily at a low angle, close to the wall rather than straight out.

It peels off cleanly in one full layer, wall stays bare. That is strippable wallpaper, most commonly vinyl or a modern peel and stick. This is the best case. Keep pulling.

A vinyl top layer peels off and leaves a fuzzy paper backing stuck to the wall. That is peelable wallpaper. The top comes off dry, the backing needs water or stripper. Two stages, both manageable.

It tears into small flakes and fights you the whole way. That is traditional non-strippable wallpaper, or several layers of it. This one needs soaking, steaming, or chemical stripper.

Bonus finding. If the corner reveals a second pattern underneath, you have layers. Every layer roughly doubles the time, and old homes sometimes hide four or five. Budget accordingly before you commit to a weekend.

Do the corner test in two or three separate spots. Rooms get repapered in pieces, and it is common to find strippable vinyl on three walls and 1970s traditional paper behind the built in on the fourth.

Step 2: is the wall drywall or plaster?

This matters more than the paper type, because it sets how much water the wall can survive.

The tap test. Knock on the wall with a knuckle. Drywall gives a hollow, drummy sound between studs and a duller thud right on a stud. Plaster over wood lath sounds solid and dense almost everywhere, with a slightly higher pitch.

The screw test. Drive a drywall screw into a spot you will cover later, ideally inside a closet or behind furniture. Drywall accepts it easily and produces soft white or gray dust. Plaster resists, produces gritty white dust, and often makes the screw wobble as it hits lath and then the gap between lath.

The edge test. Pull off an outlet cover, cut the power first, and look at the cut edge of the wall material at the box. Drywall shows an unmistakable sandwich: paper, white or gray gypsum core, paper. Plaster shows a solid mass, usually 3/4 to 1 inch thick, sometimes with wood lath visible behind it.

The age hint. Homes built before roughly 1950 are usually plaster. Homes built after about 1960 are almost always drywall. The 1950s go either way, and additions and remodels mean one house can have both.

Why drywall is the real risk

Drywall is a gypsum core wrapped in paper facing. That facing is the surface everything else sticks to, and it is glued to the core, not fused to it. Soak it and the glue between paper and core lets go.

When that happens, your scraper does not peel wallpaper off drywall. It peels the drywall's own paper off the gypsum, leaving a fuzzy, gray, slightly spongy patch. Every one of those patches needs to be sealed and skim coated before paint, or it will telegraph through as a rough, blotchy area forever.

Plaster is different. It is a solid mineral wall with no paper skin to lose. It tolerates far more water, longer dwell times, and a steamer held in one place for a minute. Steaming plaster is genuinely the easy version of this job.

The practical rule. On drywall, use the least water that works, work in small sections, and never let a section sit wet for more than about 15 minutes. On plaster, soak it as long as you like, but keep water off the wood trim and out of the outlet boxes.

One more drywall warning. Unprimed drywall under wallpaper is a bad sign. Builders who papered directly over bare drywall without a coat of primer or sizing left nothing between the wallpaper glue and the paper face. Those walls almost always tear. If your corner test lifts a dime sized flake of drywall paper with the wallpaper, plan on skim coating the whole room and consider the skim coat option below.

The four removal methods compared

Most real rooms use two of these. Dry strip the vinyl face, then soak or steam the backing. That combination handles the majority of houses.

Prep the room properly

This takes 20 minutes and saves a whole category of problems.

Kill the power to the room at the breaker, then remove outlet and switch covers and tape over the openings with painter's tape. Wet stripper running into a live box is the single genuine hazard in this job. Test the outlets with a non contact tester before you tape.

Protect the floor with plastic sheeting under canvas drop cloths. Plastic alone is a slip hazard when wet. Tape the plastic to the baseboard so wet paper and glue do not slide underneath it.

Move or center the furniture and cover it. Wallpaper glue is water soluble now and will not be after it dries on your sofa arm.

Have a trash setup. Wet paper is heavy and gets everywhere. A contractor bag inside a bucket, moved along the wall with you, beats chasing scraps across a floor.

Ventilate. Open windows, run a fan pointed out. This matters most with chemical stripper and most for your comfort with a steamer, which turns the room into a sauna fast.

Method 1: dry strip

If the corner test peeled clean, you are done reading about methods.

Lift a corner at the top of a seam, get both hands on it, and pull down and away at roughly a 15 degree angle to the wall. Slow and steady beats fast. When a strip tears off, start again at the new top edge rather than chasing the torn piece.

Work top down so gravity helps. If a strip narrows to a point, stop, go back to the widest remaining edge, and restart there.

Even on a clean dry strip, run your hand over the wall afterward. Strippable vinyl usually leaves a thin film of adhesive behind, which still needs the residue treatment further down this page.

Method 2: soak and scrape

The classic method, and the one most people picture.

Mix the solution. Hot water plus a few tablespoons of dish soap per gallon works. So does one part liquid fabric softener to three parts hot water. Neither is magic. What actually does the work is time and heat, so the point of any additive is to slow evaporation and help the water spread.

Score first if the surface is water resistant. See the scoring section below, and read the drywall warning before you touch a scoring tool.

Apply generously with a garden sprayer or a paint roller. A pump sprayer covers faster. A roller wastes less and drips less.

Wait, then reapply. The first coat wets the paper. The second coat, applied 5 minutes later, actually reaches the glue. Total dwell is usually 10 to 15 minutes on drywall and up to 20 minutes on plaster.

Scrape with a 4 or 6 inch stiff putty knife held at a low angle, no more than about 30 degrees to the wall. Round the sharp corners of the blade with a file first. Square corners are exactly what gouges drywall.

Work a section about 3 feet wide at a time. Larger sections dry out before you reach them and you end up re-wetting the same wall three times.

If the paper is not releasing after 20 minutes of soaking, more water is not the answer. Switch to a steamer or a chemical stripper.

Method 3: steamer

A wallpaper steamer pushes hot vapor through the paper and softens the glue faster than soaking. It shines on multiple layers and on old traditional paper over plaster.

Hold the plate flat against the wall for 20 to 30 seconds, then move it to the adjacent spot and scrape the area you just steamed while it is still hot. Steaming and scraping alternate continuously, which is why this goes faster than soak and scrape once you get a rhythm.

Safety, and this is not a formality. Steam at the plate is around 212 degrees F and it burns instantly. Wear long sleeves, gloves, and eye protection. Never hold the plate above your face, because condensate runs down the hose and drips. Keep the reservoir off the floor where you walk.

On drywall, keep it moving. Thirty seconds in one spot is the upper limit. Sixty seconds is how you get a torn face. On plaster you can hold it as long as it takes.

Watch ceilings and adjacent rooms. Steam gets into seams and can lift joint compound at inside corners. Do not steam a ceiling corner for a minute expecting nothing to happen.

Method 4: chemical stripper

Enzyme based wallpaper strippers, usually sold as a concentrate you mix with hot water, break down the starch or clay in old adhesives instead of just wetting them. They are the right call in two situations: paper that was painted over, and drywall where you want to minimize total moisture and get more chemical action per drop of water.

Score first, because stripper cannot get through a paint film any better than water can. Apply, let it dwell for the full time on the label, usually 15 to 30 minutes, and keep the surface wet the whole time. A stripper that dries out has stopped working.

Read the label, ventilate, wear gloves and eye protection, and keep it off finished floors and trim. Most modern products are low odor and relatively mild, but "biodegradable" on the front of the jug does not mean it belongs on your hands or your hardwood.

Scoring tools, and the trap in them

A scoring tool is a handheld disc of small toothed wheels you run over the wallpaper in overlapping circles. It perforates a water resistant face so liquid can reach the glue.

Use it when the paper is vinyl, is painted over, or simply refuses to absorb anything. Skip it entirely when water is already soaking in, because you gain nothing and add risk.

Here is the trap. On drywall, aggressive scoring causes the exact damage you are trying to avoid. Those little wheels do not know where the wallpaper ends and the drywall face begins. Press hard and you punch several hundred holes through the wallpaper, through the drywall's paper facing, and into the gypsum. Then you spray water into every one of them. You have just manufactured the tear you were worried about.

Do it this way instead. Light pressure, just enough that you can feel the wheels catch. Move in loose overlapping circles, not scrubbing. Cover the area once and stop. When you are done, the wallpaper should look faintly textured, not shredded. If you can see white gypsum dust, you went too deep.

On plaster, scoring is nearly risk free and you can lean on it.

Removing adhesive residue, and the water test

Almost every removal leaves glue behind, and it is invisible when dry. This is the step that separates a job that lasts from one that fails in six months.

Mix hot water with a little dish soap, or use the same stripper solution at half strength. Wet a 3 foot section, wait 5 minutes, then work it with an abrasive sponge or a nylon scrub pad. Squeegee or scrape the slurry off with a wide putty knife into your bucket, then wipe the area with a clean damp sponge and rinse the sponge often. Rinsing matters. A dirty sponge just relocates glue.

Change the rinse water frequently. When your bucket looks like weak tea, it is putting glue back on the wall.

The water test. After the wall is fully dry, spritz a small area with plain water and wait 60 seconds, then touch it. If it feels slick, tacky, or slightly slimy, there is still adhesive there. Clean, glue free wall feels like damp paper or damp plaster, plain and slightly rough. Test several spots, especially near the ceiling and above the baseboard where people rush.

Why this matters so much. Latex paint over old wallpaper adhesive reactivates the glue. The water in the paint softens it, the paint film shrinks as it cures, and the two fight each other. You get bubbling, crazing, alligator patterns, or paint that lifts off in sheets a month later. There is no fix short of stripping it all back down.

If you cannot get every trace off, an oil based or shellac based primer seals whatever is left. That is the insurance policy, not the plan.

Repairing a torn drywall face

If the drywall paper tore, do not just spread joint compound over it. Wet torn facing is fuzzy and will keep absorbing moisture from the mud, and loose flaps will telegraph through.

1. Let it dry completely, a full 24 hours.
2. Cut away loose flaps with a sharp utility knife so all remaining paper is bonded down. Do not peel further than the flap goes.
3. Seal the exposed gypsum with an oil based or shellac based primer, or a purpose made drywall sealer. This step is mandatory. Unsealed gypsum sucks water out of joint compound and leaves a chalky, weak patch.
4. Skim coat the sealed area with lightweight joint compound, feathering 6 to 8 inches past the damage.
5. Sand lightly with 120 to 150 grit once dry, then prime again.

Small torn areas take two thin coats. If more than about a quarter of the wall tore, skim coat the entire wall instead of patching, because a dozen feathered patches never look flat under a raking light.

For the full technique on cutting, mudding, feathering, and sanding, see how to patch drywall. Our drywall calculator sizes sheets and compound if a wall turns out to be beyond patching.

Sealing primer before paint

Never put finish paint straight onto a stripped wall. Prime it first, and pick the primer based on what happened during removal.

Clean removal, no tearing, glue test passed. A quality water based drywall primer or a PVA primer is fine.

Any residual glue you could not remove, or any yellow or brown staining. Use a shellac based primer such as a stain blocking sealer. Shellac is the one that reliably locks down old adhesive and stops it reactivating.

Torn drywall face, skim coated. Oil or shellac based primer on the sealed gypsum, then your skim coat, then a standard primer over the finished surface.

Give the wall a light 220 grit sanding after priming. Stripped walls are always slightly rougher than they look, and one pass makes the finish coat look like new construction. Then follow how to paint a room for the cut in and roll sequence, and our paint calculator for how many gallons the room actually needs.

Skim coating over wallpaper instead of removing it

Sometimes the smartest move is to leave the paper on the wall and bury it. This is a legitimate technique, not a shortcut, but it has real conditions.

It is defensible when:

• The wallpaper is bonded tight everywhere with no loose seams, bubbles, or lifting corners.
• The wall is drywall that tears badly, and test patches proved removal will destroy the face anyway.
• There is a single layer, not four.
• The paper is thin and smooth, not heavy embossed vinyl or grasscloth.
• You are prepared to skim coat the entire wall properly, two or three coats, corner to corner.

It is a bad idea when:

• Any edge is lifting or any seam is loose. Those will telegraph and eventually pop.
• The paper is textured, embossed, or has fabric or foil in it.
• There are multiple layers, which means multiple glue lines that can all fail at once.
• The room is a bathroom, kitchen, or laundry. Humidity gets behind the paper and lifts everything you put over it.
• There is any sign of moisture, mold, or a past leak on that wall.

How it is done. Seal the paper first with an oil or shellac based primer, which prevents the water in the joint compound from soaking the wallpaper and releasing its glue. That primer is not optional. Then skim two to three thin coats of joint compound over the whole wall, sanding between coats, then prime again before paint.

Be honest about the tradeoff. You are permanently committing that wall. If the paper under the skim coat ever lets go, the repair means removing everything back to bare wall. Do it where removal genuinely destroys the drywall, not just because removal is tedious.

Pre-1978 homes: what is under the wallpaper

If the house was built before 1978, assume any paint under or around that wallpaper contains lead until a test says otherwise. That includes painted plaster, painted drywall, and the trim you are scraping against.

Never dry sand or dry scrape it. Dry sanding is the single worst thing you can do, because it makes fine lead dust that spreads through the house and settles where kids and pets are. Wet methods, which wallpaper removal mostly is anyway, keep the dust down, which is one quiet advantage of soaking over scraping dry.

Get a lead check swab from a hardware store for a quick screen, or hire a certified lead inspector for a real answer. If you find lead and the job involves disturbing more than a small area of paint, hire an EPA Lead Safe certified contractor. This is a legal requirement for paid contractors working on pre-1978 housing, and it is genuinely the right call for your own household.

Homes built before 1990 can also contain asbestos in old joint compound, textured ceiling coatings, and some sheet materials. If you plan to sand old joint compound in a pre-1990 home, have it tested first. A lab sample is cheap against the alternative. Do not sand it and hope.

Cost and time: DIY versus hired

Removal is quoted by the square foot of wall, and the rate climbs steeply with each thing on this list. Use it to read a bid and to work out where your own room sits.

Materials and labor are listed separately on purpose. Get your quotes on the same scope: same square footage, same answer on how many layers are up there, and the same statement on whether adhesive removal and wall repair are included. The condition of the wall underneath moves the price more than anything else on this list, which is why a bid given over the phone is worth very little.

Worked example: one 12 by 14 bedroom

The room. 12 by 14 feet, 9 foot ceilings, one door, two windows. Traditional single layer paper on drywall from the mid 1980s.

Wall area. Perimeter is 2 x (12 + 14) = 52 feet. Times 9 foot ceilings = 468 square feet gross. Subtract one door at 21 sq ft and two windows at 15 sq ft each, so 468 minus 51 = 417 square feet of wall to strip.

Time. Soak and scrape runs about 40 to 50 square feet per hour for one person on traditional paper. Call it 417 divided by 45, or roughly 9 hours of stripping. Add 3 hours for adhesive removal and 1 hour for prep, so about 13 hours total, which is a real two day weekend.

Materials. Pump sprayer, two putty knives, a scoring tool, abrasive sponges, a jug of stripper concentrate, and drop cloths. That is the whole list, and it is a small fraction of what the same room costs hired. Add a gallon of shellac based primer if the glue test comes back tacky, which is the most expensive item on the list.

Hired. Contractors price this off the same 417 square feet, at their single layer rate, before any wall repair. Ask for wall repair to be quoted as a separate line rather than folded in, because nobody can see the drywall face until the paper is off.

If the drywall tears. Say a third of the room, 140 sq ft, loses its face. Skim coating that is its own per square foot rate on a bid, and it can add a substantial share on top of the removal itself. DIY it is a couple of buckets of compound and 8 hours of your time. That gap is exactly why the corner test comes first.

Then paint. Use our square footage calculator to convert the room to paintable area and check cost to paint a house interior for what drives the finish coat.

Frequently asked questions

What is the easiest way to remove old wallpaper?

Dry stripping, when the paper allows it. Test a corner and pull, and if the whole layer comes away clean you are done in under an hour with no water and no chemicals. When it does not, hot water with dish soap plus 15 minutes of dwell time is the cheapest next step, and a rented steamer is the fastest option for multiple layers on plaster walls.

Can you paint over wallpaper instead of removing it?

You can, but only over tight, smooth, single layer paper with no lifting seams, and only after sealing it with an oil or shellac based primer. Water based paint straight over wallpaper reactivates the glue and causes bubbling. Even done right you will still see the seams, which is why skim coating over the sealed paper gives a much better result than paint alone.

Does vinegar remove wallpaper?

A vinegar and hot water mix helps a little, mostly by breaking down old starch paste, but it is not dramatically better than dish soap and hot water. What actually does the work is heat and dwell time. If plain hot water is not releasing the paper after 20 minutes, a real enzyme stripper or a steamer is a better use of your afternoon than a stronger vinegar mix.

How do I know if the wallpaper glue is fully removed?

Spritz plain water on a dry, cleaned area and wait a minute, then touch it. Slick, tacky, or slimy means glue is still there. A truly clean wall feels plain and slightly rough, like damp paper or damp plaster. Test near the ceiling and just above the baseboard, since those are the spots people rush.

Will a steamer damage drywall?

It can, easily. Steam softens the glue that holds the drywall's paper facing to the gypsum core, so a plate held in one place for a minute will tear the wall face. Keep it moving, 20 to 30 seconds per spot maximum on drywall, and scrape while the area is still hot. On plaster you have far more room to work, since there is no paper skin to lose.

Should I score wallpaper before soaking it?

Only if water is not soaking in on its own, which usually means a vinyl face or paint over the paper. Scoring is not free on drywall: heavy pressure punches through the wallpaper into the drywall face and creates the damage you were trying to prevent. Use light pressure, one pass in overlapping circles, and stop as soon as the surface looks faintly textured.

How long does it take to remove wallpaper from one room?

Strippable vinyl in an average bedroom takes 2 to 4 hours including cleanup. Traditional single layer paper on the same room runs 8 to 14 hours across two days once you include adhesive removal. Multiple layers or painted over wallpaper can reach 30 hours, which is the point where most people rent a steamer or get a quote.

Do I need to prime after removing wallpaper?

Yes, always. Bare, freshly stripped wall is porous and often carries traces of adhesive, so finish paint applied directly to it goes on blotchy and can bubble. Use a standard drywall primer after a clean removal, and a shellac based stain blocking primer if any glue residue or staining is left behind.

The short version

Test a corner before you buy anything, then find out whether you are working on drywall or plaster. Those two facts decide the method, the risk, and the budget.

Drywall is the fragile one, because its paper facing tears when it gets soaked. Use the least water that works, keep sections small, go light on the scoring tool, and stop if the wall face starts lifting. Plaster forgives almost everything.

Then do the two steps everyone skips. Remove the adhesive completely and prove it with the water test, and prime with a sealer before any paint. Paint over old wallpaper glue fails, and it fails in a way that costs you the whole wall.

If the drywall tore anyway, how to patch drywall covers the repair, and how to paint a room picks up from primed walls onward.
