Quick answer: paint peels off walls in Singapore mainly because of moisture (high humidity, leaks or damp walls), poor surface preparation (dust, chalky old paint, or gloss paint that was not sanded) and skipping a sealer or primer before the topcoat. To fix it properly, find and stop the moisture source, scrape off all loose paint, fill and sand the surface (skim coat it if it is uneven), apply a sealer, then finish with 2 coats of a suitable emulsion. Small patches can be a DIY job; damp walls, large areas or paint that keeps peeling are better handled by a painter. In our HDB packages, major peeling and putty repair is quoted at $40 to $290 depending on the damage (see our painting price list). Peeling on a toilet or bathroom ceiling?

Why paint peels: the main causes
- Moisture: a leak, a damp wall or constant humidity pushes water behind the paint, so it bubbles and lifts. This is the most common cause in Singapore homes.
- Poor preparation: paint applied over dust, grease, loose old paint or chalky paint has nothing firm to grip.
- No sealer on porous or patched areas: new plaster, skim coat and filler soak up the first coat unevenly, so the topcoat does not bond well. See what sealer paint is for.
- Incompatible paints: water-based emulsion over old oil-based or gloss paint that was not sanded or primed.
- Rushed coats: painting the next coat before the last one is dry, especially on humid days.
Work out the cause from where it peels
| What you see | Likely cause | What to do first |
|---|---|---|
| Bubbles or peeling on a ceiling under a bathroom | Leak from the unit above or a pipe | Get the leak fixed before any repainting |
| Peeling at the bottom of a wall or near a window | Damp from outside or rainwater getting in | Check window seals and outside walls; let the wall dry |
| Paint coming off in large sheets on a dry wall | Poor adhesion: dust, chalky old paint or no sealer | Scrape back to a firm surface, seal, then repaint |
| Small flakes around a patched crack | Filler not sealed before painting | Sand the patch, seal it, then touch up |
| Peeling with black spots | Damp plus mould | Clean the mould, fix the damp, use an anti-mould paint |
How to fix peeling paint properly
- Stop the moisture. Fix the leak or damp and let the wall dry fully; a fan or dehumidifier helps.
- Scrape off everything loose with a scraper or wire brush until the edges are firm.
- Fill and sand. Fill holes and dips, then sand smooth. If a large area is uneven, it may need a skim coat (see wall plastering and skim coat).
- Clean and dry the surface so no dust is left.
- Apply a sealer on the scraped and patched areas.
- Repaint with 2 coats, waiting for the recoat time on the tin between coats. In damp rooms, use an anti-mould paint.
DIY or call a painter?
A small patch on a dry wall is a reasonable DIY job. Call a painter if the wall is still damp, the area is large, the ceiling is affected, or the paint keeps peeling after you have repainted it. That usually means the cause has not been fixed.

How to stop it coming back
- Ventilate bathrooms and kitchens and wipe condensation off ceilings.

- Never paint over a damp, dusty or flaking surface.
Frequently asked questions
Can I paint over peeling paint?
No. New paint on top of loose paint will peel with it. Scrape back to a firm edge, fill, sand and seal first.
Why is the paint on my ceiling bubbling?
Bubbling on a ceiling usually means water is getting in, often from a leak in the bathroom or pipes above. Fix the leak and let the ceiling dry before repainting.
How long should I wait before repainting a damp wall?
Until it is completely dry, which can take several days after a leak is fixed. Painting too early is the most common reason repairs fail.
