Staring at outdated wallpaper and dreading the removal process? You aren’t alone. Scraping layers of old paper is a massive headache, but there is a shortcut. You can paint right over it.
While purists might tell you removal is the only option, that isn’t always true. With the right prep work and materials, you can cover that old pattern and give your room a fresh, modern look without the mess of stripping walls.
Key Takeaways
- Painting over wallpaper is a viable option if the paper is firmly adhered to the wall and free of texture.
- Never use water-based primer on wallpaper; the moisture can reactivate the glue and cause bubbling. Always use an oil-based or shellac-based primer.
- Repair loose edges and seal seams with adhesive or joint compound before painting to ensure a smooth finish.
- If the wallpaper is textured, fabric-backed, or already peeling significantly, removing it 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?
This is the big debate. 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 accumulates dust and grease over the years. Paint won’t stick to grease. Wipe the walls down with a damp cloth.
For kitchen or bathroom wallpaper, use a diluted TSP solution to cut through the grime.
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 most critical step. You must use an oil-based primer, like Zinsser Cover Stain or a shellac-based primer.
Why not water-based primer? Wallpaper adhesive is water-soluble. If you use a water-based primer (or latex paint directly), the water soaks through the paper and dissolves the glue underneath. Your wallpaper will bubble and slide off the wall. Oil-based primer seals the surface without disturbing the adhesive.
Ensure the room is well-ventilated, apply the primer with a roller, and let it dry completely.
4. Paint the Walls
Once the oil-based primer is cured, you can use any paint you like, including standard latex or acrylic wall paint.
Cut in the corners and edges with a brush, then roll the walls using vertical strokes. Two coats are usually necessary to cover the print of the underlying wallpaper completely.
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. Apply a thin layer of joint compound over the vertical seams using a wide putty knife.
Feather the edges so it blends into the paper. Let it dry, then sand it smooth. This makes the seam invisible once 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 this cleaning step is vital.
FAQs
Can I use water-based primer on wallpaper?
No, you should never use water-based primer on wallpaper. The water in the primer soaks through the paper and reactivates the water-soluble adhesive underneath. This causes the wallpaper to lift, bubble, and peel away from the wall. Always use an oil-based or shellac-based primer to seal the surface first.
Will painted wallpaper peel over time?
Yes, eventually painted wallpaper may peel. Painting adds weight to the paper, and the underlying adhesive naturally degrades over time. However, if the wallpaper was adhered well initially and you used the correct oil-based primer, the finish can last for many years without issues.
Can I paint over textured wallpaper?
Yes, but the texture will show through the paint. If you want a smooth wall, you need to apply a “skim coat” of joint compound over the entire surface to fill in the texture before priming. If you don’t mind the texture, you can simply prime and paint it like normal.
Does painting wallpaper ruin the walls?
Painting wallpaper makes it much harder to remove later. The paint seals the paper, making it difficult for stripping solutions to penetrate the glue in the future. If you plan to remove the wallpaper eventually, painting over it now will double the workload later.
Bottom Line
Painting over wallpaper is a legitimate DIY hack that can save you time and money, provided your walls are in decent shape.
Just remember the golden rule: Oil-based primer is non-negotiable. If you prep correctly and seal those seams, you can achieve a finish that looks just like a fresh coat of paint on drywall.
