Mould on bathroom ceilings returns again and again in many Nigerian homes because regular paint traps moisture. The best fix in 2026 is a dedicated anti-mould primer + mould-resistant topcoat. Here’s the exact method that stops mould from coming back.
Why normal paint fails on bathroom ceilings
- Steam & condensation penetrate porous paint
- No anti-mould primer used
- Standard matte holds moisture like a sponge
- Poor ventilation lets spores regrow
Step-by-step fix – how to stop mould on bathroom ceiling in Nigeria
- Improve ventilation – install/exhaust fan or leave window open after shower (critical first step)
- Remove all visible mould – bleach solution (1:10 bleach:water) + scraper
- Sand lightly to roughen surface
- Apply anti-mould primer – Prestige Timeless Anti-Mould Ceiling Primer (2 thin coats)
- Topcoat – Prestige Timeless Anti-Mould Eggshell or Semi-Gloss (2 full coats)
- Eggshell for most bathrooms
- Semi-Gloss if very steamy
Quick finish recommendations
- Normal bathroom → Anti-Mould Eggshell
- Very humid / no exhaust fan → Anti-Mould Semi-Gloss
- Already black mould history → Anti-Mould Primer + Semi-Gloss
Expected result Done correctly + better ventilation, mould should not return for 3–7 years.
