How to Remove Wallpaper Before Painting: A Complete Step by Step Guide

Quick answer: To remove wallpaper, first identify the type, then peel any strippable paper dry. For traditional paper, score the surface, soak it with hot water and a wallpaper stripper solution or a steamer, and scrape it off gently with a putty knife. The critical final step is washing off every trace of old paste, because paint will not stick over leftover adhesive. Once the wall is clean and dry, repair any damage and prime before you paint.

Wallpaper removal is the kind of job that looks simple and turns into a weekend if you skip steps. Before you start, it helps to know how much wall you are dealing with and what the repaint will cost.

Why removing wallpaper matters before you paint

Paint does not bond to wallpaper paste. Old wallpaper adhesive stays slightly water soluble and tacky for years. If you paint over residue, the moisture in the paint can reactivate the paste, which leads to bubbling, peeling, and a finish that lifts in sheets later. Stripping the paste is not optional if you want the new color to last.

Wallpaper seams and texture telegraph through paint. Even if the paper is stuck tight, every seam line and embossed pattern shows through a coat of paint once the light hits it at an angle. Removing the paper gives you a flat, uniform surface that reads as a real painted wall rather than painted paper.

Trapped moisture causes problems down the line. Paper and paste hold humidity against the wall. In bathrooms and kitchens that can feed mildew behind the paper. Taking it off lets you see and treat the actual wall surface before you seal everything under new paint.

Identify the type of wallpaper you have

Strippable wallpaper peels off dry. This is the easiest type. Lift a bottom corner with a putty knife and pull gently at a low angle. If the paper comes away in large sheets without water, you have strippable paper and most of the job is just patient peeling. Many newer papers are designed this way.

Traditional paper needs soaking. Older or budget wallpaper is porous and bonded with a paste that only releases when it gets wet. If a dry corner tears into small pieces or refuses to lift, you are dealing with traditional paper that needs water, a stripper solution, or a steamer to loosen the adhesive.

Vinyl and vinyl coated wallpaper resist water. Vinyl has a plastic top layer that blocks moisture, so soaking alone will not work until you break that barrier. You usually peel off the vinyl face layer first, which often leaves a paper backing and paste behind, then soak and scrape that backing like traditional paper.

Painted over wallpaper is the hardest case. If someone already painted over the wallpaper, the paint seals the paper so water cannot reach the paste. You will need to score the surface aggressively so the stripping solution can penetrate, and expect a slow job. Test a small area first to decide whether removal or a skim coat over the top makes more sense.

Tools and materials you need

Gather these before you start so you are not running to the store mid soak. Wallpaper removal is messy, and stopping halfway lets sections dry back out.

• A wide putty knife or wallpaper scraper, ideally with a slightly flexible blade so you do not gouge the wall.
• A scoring tool to perforate the surface so water can reach the paste.
• A wallpaper stripper concentrate or enzyme based gel, mixed with hot water in a pump sprayer or a bucket.
• A wallpaper steamer if you have a large area or stubborn paper. A steamer is the fastest method for traditional paper.
• Drop cloths or plastic sheeting, painters tape, and old towels, because this job produces a lot of wet paper and drips.
• A sponge, clean rags, and a second bucket of clean water for the final paste rinse.
• Rubber gloves and eye protection, especially when using a steamer.

Step by step: how to remove wallpaper

Step one: prep and protect the room. Move furniture out or to the center and cover it. Lay drop cloths along the baseboards, tape plastic over outlets and switches after turning off power to the room, and have a trash bag ready for wet scraps. Wet wallpaper is heavy and drippy, so protect floors well.

Step two: peel any strippable layer first. Test each wall by lifting a bottom corner. Where the paper peels dry, keep pulling slowly at a low angle to take off as much as you can without water. Every dry sheet you remove is less soaking and scraping later.

Step three: score the surface. For paper that will not peel dry, run a scoring tool over the wall in small circles. The goal is to perforate the face just enough for water to pass through to the paste. Do not press so hard that you cut deep gouges into the drywall underneath.

Step four: soak with hot water and stripper, or steam it. Mix your wallpaper stripper with hot water and apply it generously to a manageable section, then let it sit so the paste softens. With a steamer, hold the plate against the paper until the area feels hot and damp. Work in sections so the wall stays wet when you scrape. Soaking is the step people rush, and rushing it is why paper tears into confetti.

Step five: scrape gently. Once the section is saturated and the paste has loosened, slide your putty knife under an edge and lift the paper away at a shallow angle. Keep the blade nearly flat so you peel the paper rather than digging into the wall. If it resists, it needs more soaking time, not more force.

Step six: remove all the paste residue. This is the most important step. After the paper is off, the wall will still have a slick or slightly sticky film of old adhesive. Wash the entire surface with warm water and a sponge, changing the water often, until the wall no longer feels tacky when it dries. Paint will not stick over paste, so do not shortcut this. A little dish soap or a dedicated paste remover helps cut stubborn glue.

Step seven: rinse and let the wall dry fully. Wipe the wall down with clean water to remove any cleaning residue, then let it dry completely. Damp walls cause primer and paint to fail, so give it time, ideally a full day with good airflow.

Assess and prep the wall after removal

Check for torn paper face and gouges. Removal often pulls up bits of the drywall paper face or leaves scrape marks. Run your hand and eye over the wall in raking light. Small dents fill with joint compound, but a wall where the paper face tore over a large area needs more than spot filling.

Skim coat if the surface is rough or torn. When the drywall face is damaged across a section, the cleanest fix is to skim coat it. Our guide on how to skim coat a wall walks through floating a thin layer of compound over the whole area to restore a smooth, paintable surface. Let it dry, then sand it flat.

Spot prime any exposed drywall. Where the paper face tore off, the raw gypsum and torn paper edges will soak up paint unevenly. Sealing those spots before your full prime coat prevents flashing in the finished wall.

Follow the full prep routine. Beyond paste removal, the wall still benefits from a standard prep pass. Our overview of how to prep walls for painting covers cleaning, filling, sanding, and caulking so the surface is truly ready.

Prime and paint after removing wallpaper

Always prime a stripped wall. A wall that held wallpaper has uneven porosity from old paste, patched compound, and bare drywall in spots. Primer evens all of that out so your color goes on uniformly. Our guide on whether you need primer before painting explains when a dedicated primer beats a self priming paint, and stripped wallpaper is a clear case for priming.

Let primer cure, then paint. Give the primer the full dry time on the label before topcoating. Once it is ready, paint as you would any room. Our walkthrough on how to paint a room covers cutting in, rolling, and getting an even two coat finish.

Budget the paint you need. Now that the wall is bare, you can measure accurately. Plug the room dimensions into the paint cost calculator to see how much primer and paint to buy so you finish in one trip.

When painting over wallpaper is acceptable and when it is not

It can be acceptable when removal would destroy the wall. In older homes, wallpaper is sometimes the only thing holding fragile plaster together, and stripping it can pull the wall apart. If the paper is firmly bonded everywhere, the seams are flat, and there is no peeling or moisture damage, sealing it with the right primer and painting over it is a reasonable compromise.

It is not acceptable when the paper is loose, textured, or in a wet room. Lifting seams, bubbles, heavy texture, or vinyl with a slick face will all telegraph or fail under paint. In bathrooms and kitchens, painting over paper traps moisture and invites mildew. In those cases, removal is the right call even though it is more work.

If you do paint over it, prep it properly. Glue down loose seams, sand the edges smooth, clean the surface, and use an oil based or shellac based primer to seal the paper so the water in your topcoat does not loosen the paste. This is a last resort, not the default.

Common wallpaper removal mistakes to avoid

Rushing the soak time. The single most common mistake is scraping before the paste has fully softened. Dry or barely damp paper tears into tiny pieces that take hours to pick off. Give each section enough soak time and the paper lifts in big satisfying sheets. Patience here saves you far more time than it costs.

Gouging the drywall with the scraper. Holding the putty knife at too steep an angle, or using one with sharp square corners, digs into the soft drywall face. Keep the blade nearly flat, round the corners of a metal scraper slightly, and let the soaked paste do the work instead of forcing the blade.

Leaving paste behind because the wall looked clean. Dried paste can look like nothing at all yet still ruin your paint job. Always test by touch once an area dries. If it feels even slightly slick or tacky, there is still adhesive to wash off. When in doubt, rinse one more time.

Skipping primer to save a step. A stripped wall has patchy porosity that no single coat of color will hide. Painting straight onto bare, paste streaked drywall almost always flashes and looks uneven. The prime coat is what turns a stripped wall back into a normal paintable surface.

Frequently asked questions

Do I really have to remove all the wallpaper paste?

Yes. Old paste stays water soluble and tacky, and the moisture in fresh paint can reactivate it, which causes bubbling and peeling. Wash the wall until it no longer feels sticky when dry before you prime or paint.

What is the fastest way to remove wallpaper?

For traditional paper, a wallpaper steamer is usually fastest because it softens the paste quickly across large sections. For strippable paper, dry peeling is faster still. The right method depends on the paper type you identify first.

Can I just paint over wallpaper instead?

Sometimes, if the paper is firmly bonded, flat, and in a dry room. Glue down loose seams, sand, clean, and seal with an oil or shellac based primer first. Avoid it in bathrooms, kitchens, or anywhere the paper is loose or textured.

How do I know what type of wallpaper I have?

Lift a bottom corner with a putty knife. If it peels dry in large sheets, it is strippable. If it tears into small wet pieces or will not lift, it is traditional paper that needs soaking. A slick plastic face means vinyl.

What if the drywall face tears during removal?

Small tears fill with joint compound and sand smooth. If the paper face tore over a large area, skim coat the section to restore a flat surface, then spot prime any exposed drywall before your full prime coat.

How long should the wall dry before painting?

Let the wall dry completely after the final paste rinse, ideally a full day with good airflow. Then prime, let the primer cure per the label, and paint. Painting a damp wall causes primer and paint to fail.
