Problem Solved
HDB Mould & Humidity Paint Solutions: Stop It Coming Back
How do you stop HDB mould returning?
84% average humidity in Singapore means HDB mould returns unless walls are treated before repainting. Pico X Health uses anti-mould treatment, sealer on every wall, and antimicrobial paint on problem areas such as bathroom ceilings and wardrobe backs. Non-limewash HDB repaints finish in 1 day, with a 5-year peeling and workmanship warranty.
If mould keeps returning to the same HDB wall after every repaint, the paint isn't the problem — the prep is. Here's what actually stops it, and what's just covering it up.
Why HDB walls grow mould
Singapore averages 84% humidity. Three combinations cause 95% of HDB mould:
- Bathroom ceiling. Hot shower steam condenses on cool ceiling. Spores colonise within 6 months without anti-mould paint.
- Wall behind wardrobe / sofa. No air circulation; surface temperature drops, condensation forms.
- Wall under window AC unit. Condensate drips onto wall during cycling.
Why a normal repaint doesn't fix it
Standard emulsion sits on the surface. Mould spores below are still alive — they break through within months.
Who does what
The mould itself — inspection, treatment, clearance and any waterproofing — is carried out by our sister company, Pico X Mould Removal, including their HDB mould removal costs and warranty. Once the surface is sound and dry, we come in with the paint.
The paint side: what we supply
For treated walls and ceilings we specify anti-mould systems built for Singapore humidity — Zinsser Perma-White on bathroom ceilings and wet areas, and Breathe Antimicrobial in bedrooms and living areas. Every full-unit repaint we quote already includes a premium Gush anti-mould sealer.
Bathroom ceilings specifically
The mould-prone zone is the strip directly above the shower. If there is an active leak from the unit above, no paint will hold — that has to be resolved first. See ceiling mould and waterproofing on the mould removal site, then read our bathroom ceiling paint guide for the finish.
