Whether to remove wallpaper or paint over it depends on two things: what kind of paper is on the wall, and how well it is stuck. Painting over can work on paper designed to be painted, such as lining paper or woodchip, provided it is bonded firmly edge to edge. For vinyl, patterned, loose, damaged or heavily layered paper, removing it first is usually the better decision. Water-based paint can soften the paste and lift the seams, and the paper’s joins and texture tend to show through the finish. The checks below take a few minutes and usually settle the question.
Five checks that decide it
1. What kind of paper is it?
Lift a corner or look along a seam. The type of paper matters more than anything else:
| Paper on the wall | Painting over it |
|---|---|
| Lining paper | Made to be painted. A good candidate if it is smooth and firmly stuck |
| Woodchip or other relief paper | Designed for painting and often already painted. Repainting works if it is sound, but you keep the texture |
| Standard printed paper | Possible, but inks can bleed through and seams often lift when wetted |
| Vinyl | Poor. The plastic face gives emulsion little to grip and the joins show |
| Backing left behind from peeled vinyl | Not intended as a finished surface; usually better removed |
| Non-woven (paste-the-wall) paper | Rarely worth it, because this type often peels off dry in full lengths |
2. How well is it stuck?
Run a hand along every seam, round the corners, at the skirting and ceiling line, and round sockets and door frames, where paper is most likely to have been disturbed. Press flat areas gently. Lifting edges, bubbles, or a hollow or crackling feel under the hand all mean the paper has let go in places. A few small lifted edges can be stuck back down. Large areas that move when pressed cannot be painted reliably.
3. How many layers are there already?
Look at a cut edge by a light switch or a corner. If there are several layers of paper, or the paper has already been painted more than once, every extra coat adds weight and makes the bond more likely to fail. It also makes the paper harder to get off later: painted paper has to be scored and steamed, which is slower and harder on the wall underneath, as our wallpaper removal page explains.
4. What finish are you expecting?
Painted paper looks like painted paper. Joins, overlaps and any texture stay visible, and they show more under a sheen finish or when light runs along the wall from a window. A flat matt emulsion hides most. If you want the look of smooth painted plaster, painting over paper will not give you that, however carefully it is done.
5. How long does the finish need to last?
Painting over may be a reasonable short-term answer for a room you plan to redecorate properly within a year or two. For a long-term finish, or a room that will be repainted many times, the time saved now is often lost later when the painted paper has to come off anyway.
What tends to go wrong when paper is painted over
- Bubbling. Water in emulsion soaks into the paper and can soften the paste beneath it. Some bubbles flatten as the paint dries; others stay.
- Seams opening. Joins that looked tight can curl up as the paper swells and dries, leaving visible lines.
- Bleed-through. Patterns, inks and old stains on the paper can show through a light colour.
- Hidden problems stay hidden. Paper can cover cracks, blown plaster or a damp patch that has been papered over rather than fixed. Paint seals them in until they show through.
- A harder job next time. Painted paper resists water, so stripping it later takes longer and risks more damage to plaster or plasterboard.
Painting over vs removing first
| Painting over the paper | Removing it first | |
|---|---|---|
| Time now | Less, if the paper is sound | More: stripping, then washing, drying and making good |
| Finish | Joins and texture remain visible | Depends on the wall underneath; can be made smooth |
| Risk of problems | Bubbles, lifting seams, bleed-through | Surprises under the paper, such as blown plaster or a torn plasterboard face |
| Next time you decorate | Harder: painted paper has to be scored and steamed | Straightforward repainting |
| What drives the cost | Repairs to the paper, a suitable primer, extra coats | Paper type and layers, wall condition, repairs found once it is off |
Neither route is automatically cheaper. Painting over saves the stripping, but if the paper fails within a year you pay for the removal anyway, plus the paint that is now on it.
If you decide to paint over it
When the paper passes the checks, these steps improve the odds of a finish that lasts:
- Stick down every lifted edge and seam with an overlap or border adhesive, and let it dry fully.
- Wipe the paper down lightly with a barely damp cloth. Do not soak it.
- Seal the paper with a primer suitable for painting over wallpaper. A solvent-based or shellac-based stain-blocking primer is commonly used, because it does not wet the paste the way water-based paint does and it helps stop inks bleeding through. Check the manufacturer’s guidance on the tin.
- Test a small, out-of-sight area first and leave it overnight. Bubbles or lifting there will appear across the whole wall.
- Apply two thin coats of emulsion rather than one heavy coat, and let each dry properly.
Avoid heavy sanding of the paper between coats. It can scuff through the face and leave a fuzzy surface.
Situations where the answer is fairly clear
- Sound lining paper in good condition: paint it.
- Woodchip that is firmly stuck and already painted: repainting is fine if you are happy with the texture. If you want smooth walls, it needs to come off.
- Vinyl or patterned paper: remove it.
- Paper lifting in a kitchen or bathroom: remove it. Steam and condensation will keep working on any weak bond.
- Several layers, or paper already painted more than once: removal is usually the better long-term choice.
- A rented home: check with the landlord or agent before doing either.
One thing to check before scraping anything: if what is on the wall or ceiling turns out to be a textured coating rather than paper, some coatings applied before 2000 can contain asbestos and should not be scraped or sanded until tested. The HSE’s asbestos guidance explains why.
Middle routes worth considering
The choice is not always all or nothing. On older, uneven walls, stripping and then hanging lining paper gives a consistent surface for paint without having to fill every ripple. Stripping a single feature wall and painting the rest can work where only one wall is in poor shape. If you would rather paper again than paint, the stripped wall needs sealing first, as explained on our wallpaper installation page. If you are painting once the paper is off, our interior painting preparation checklist covers what to sort out before the first coat.
Whichever way you go, it is sensible to budget for some making good once the paper is off. Cracks, old patch repairs and paste residue are common, and dealing with them properly is what wall preparation and filling covers. If you decide the paper needs to come off, Voltify Contractors’ wallpaper removal service chooses the gentlest method for the paper and wall involved and leaves the surface ready for the next stage.
Key takeaway
Paint over wallpaper only when it is a paintable type, firmly stuck everywhere, not already layered and you are happy for the joins and texture to show. If any of those fail, removing it first is usually less trouble overall.
