That dated wallpaper does not have to mean a weekend of scraping, steaming, and scoring. If the paper is stuck down tight, you can prime it and paint straight over the top for a fresh wall in an afternoon.
The catch is the prep. Skip the right primer, or paint over loose seams, and the whole job bubbles. Get those two things right and painted wallpaper can pass for a smooth, freshly coated wall.
Below is the full method: how to tell if your wall is a good candidate, the exact primer to reach for, and how to hide the seams so no one can tell paper is underneath.
Key Takeaways
- You can paint over wallpaper when the paper is smooth and stuck down tight, with no lifting seams or heavy texture.
- Use an oil-based or shellac-based primer, never a water-based one; water reactivates the wallpaper glue and causes bubbling.
- Reattach loose seams and skim the joints with thin joint compound before priming, then roll on at least two coats of paint.
- If the wallpaper is textured, fabric-backed, or already peeling, stripping it off is the safer choice.
Can You Paint Over Wallpaper?
Yes, you absolutely can paint over wallpaper. In fact, professional painters do it often when the situation calls for it.
Sometimes, the drywall underneath is old and fragile. Stripping the paper might damage the plaster or drywall surface, turning a simple renovation into a major construction project. In these cases, painting over the paper protects the structural integrity of the wall.
However, you have to be realistic. This is technically a temporary solution. Wallpaper adhesive eventually fails, and adding layers of paint adds weight to the paper. If done correctly, it can last for years, but it isn’t a permanent fix like removing it entirely.
Take Note
Avoid painting over fabric-backed vinyl or rigid textures. The paint often sits awkwardly on these surfaces, and the result looks messy. This method works best on smooth, paper-based wallpapers.
Should You Paint Over Wallpaper or Remove It?
Remove the wallpaper if you plan to stay for years or the paper is already lifting; paint over it if the paper is tight and the drywall underneath is fragile. If this is your “forever home,” I usually recommend biting the bullet and stripping the paper. It resets the room and adds value.
But if you are renting, flipping a house quickly, or dealing with walls that might crumble if you scrape them, painting is a solid alternative.
When to Remove Wallpaper
Sometimes, the shortcut isn’t worth the risk. You should strip the paper if:
- You plan to live there for decades: Do it right the first time so you don’t have to fix peeling paper five years from now.
- The paper is already failing: If you see ripples, bubbles, or peeling corners, paint will not fix it. It will actually pull the paper further off the wall.
- It is heavily textured: Unless you plan to skim coat the entire wall, that 1970s floral texture will show right through your new paint job.
When to Paint Over Wallpaper
Painting over the paper is advantageous when:
- The drywall is damaged: If removing the paper will rip the drywall paper face or crumble the plaster, leave it alone.
- The wallpaper is tight: If you can’t peel a corner with a putty knife, the adhesion is strong enough to hold paint.
- Time is a factor: Stripping wallpaper can take days. Painting over it takes hours.
Keep In Mind
Always test a small, inconspicuous area first. Paint a patch, let it dry, and wait 24 hours. If the paper bubbles or lifts, you cannot paint over it.
How to Paint Over Wallpaper
The secret isn’t the paint; it is the primer. If you skip the primer step or use the wrong kind, your project will fail.
What You’ll Need
- Paint roller and tray.
- Angled paintbrush.
- Respirator mask (for fumes).
- Rubber gloves.
- Safety goggles.
- Painter’s tape.
- Drop cloths.
- TSP (Trisodium Phosphate) cleaner.
- Oil-based or Shellac-based primer.
- Spackle or joint compound.
- Putty knife.
- Fine-grit sandpaper (150 to 180).
1. Clean the Walls Thoroughly
Wallpaper collects dust and grease over the years, and paint will not stick to grease. Wipe the walls down with a barely damp cloth, not a wet one.
For kitchen or bathroom wallpaper, use a diluted TSP solution to cut through the grime, then, according to This Old House, let the walls dry for a full 24 hours before you go any further (1).
Be Careful
Do not soak the walls. Excess water seeps into the seams and reactivates the old glue, causing the paper to bubble. Use a damp cloth, not a wet sponge.
2. Secure Loose Paper
Check every seam and corner. If anything is lifting, you must fix it now. Apply a small amount of wallpaper seam adhesive or super glue to loose flaps and press them flat.
Once the glue is dry, run your hand over the walls to feel for bumps. Sand down any rough spots gently.
3. Apply Oil-Based Primer
This is the step you cannot shortcut. Use an oil-based primer, like Zinsser Cover Stain, or a shellac-based one. Both sit on top of the paper and seal it, rather than soaking in the way a latex primer does.
Why not water-based primer? Wallpaper adhesive is water-soluble. A water-based primer (or latex paint applied directly) lets water soak through the paper and dissolve the glue underneath, so the wallpaper bubbles and slides off the wall. Oil and shellac primers seal the surface without wetting the adhesive.
Oil or shellac? Oil-based primer is the forgiving all-rounder and the easiest to roll on. Shellac-based primer grips harder, blocks old stains, and according to A Piece of Rainbow dries in about 15 to 30 minutes, and because it draws moisture out it can help settle small bubbles (2). The trade-off is a stronger smell and messier cleanup.
Not sure the wall will cooperate? Prime a small test patch and give it 24 hours. If it dries flat with no lifting or blistering, go ahead and prime the whole room.
Open the windows, run a fan, and roll the primer on in thin, even coats, then let it dry fully. One cleanup note: oil and shellac products do not wash out with soap and water, so keep mineral spirits on hand for your brushes and roller.
4. Paint the Walls
Once the primer is fully cured, you can switch to whatever paint you like, including standard latex or acrylic wall paint.
Cut in the corners and edges with a brush, then roll the walls in vertical strokes. Plan on at least two coats to bury the pattern underneath. Give latex paint about 2 to 4 hours to dry between coats; if you went with an oil-based paint, wait a full 24 hours before recoating. Rushing the second coat is how you end up with streaks and lap marks.
How to Hide Wallpaper Seams
Even after painting, the vertical seams of the wallpaper can remain visible. If you want a smooth, drywall-like finish, you need to disguise them before you prime.
Use Joint Compound
The best way to hide seams is to treat them like drywall joints. If a seam feels weak or slightly open, press a strip of fiberglass mesh tape over it first so it cannot crack later. Then spread a thin layer of joint compound over the vertical seams with a wide putty knife.
Feather the edges so the compound melts into the paper, and step up to a slightly larger knife on each pass to spread it wider and flatter. Give each coat 12 to 24 hours to dry, according to Timothy’s Toolbox, longer in a humid room, then sand it smooth. Two thin coats hide a seam far better than one thick one, and the joint disappears once it is primed and painted.
Caulk the Edges
Wallpaper often curls slightly where it meets baseboards, molding, or the ceiling. Run a thin bead of clear paintable caulk along these perimeters.
Smooth it out with your finger. This seals the edge, prevents future peeling, and gives you a crisp paint line.
Fixing Bubbles
If you missed a spot and a bubble appears after priming, don’t panic. Cut a small “X” in the bubble with a razor blade. Squeeze a tiny bit of adhesive inside, press it flat with a seam roller, wipe away the excess, and repaint that spot once dry.
How to Remove Wallpaper (If You Change Your Mind)
If you decide painting is too risky, removal is the alternative. Modern “strippable” wallpaper peels off easily, but older traditional paper requires moisture and patience.
Tools for Removal
- Step ladder.
- Wallpaper scoring tool (Paper Tiger).
- Wallpaper stripping concentrate.
- Garden sprayer or sponge.
- Wide scraper.
1. Score and Soak
Run a scoring tool over the wallpaper in circular motions. This perforates the paper so the solution can reach the glue. Mix hot water with a wallpaper stripper solution in a sprayer. Saturate the wall.
2. Wait and Scrape
Patience is key. Let the solution sit for 15 to 20 minutes. The paper should darken as it absorbs water. Use a scraper to lift the paper. If it fights you, spray it again and wait longer.
3. Wash the Residue
Once the paper is gone, the wall will still be sticky. Scrub the walls with soap and water to remove the old paste. If you paint over the paste, your paint will crack, so do not skip this cleaning step.

Bottom Line
Painting over wallpaper is a real shortcut that can save you a full day of scraping, as long as the paper is smooth and firmly stuck to the wall.
The one rule that makes or breaks the job: prime with oil or shellac, never a water-based product. Reattach loose seams, skim the joints, and lay down two solid coats, and you end up with a wall that reads as smooth drywall, not painted-over paper.
