Rising damp is one of the most frustrating problems in Nigerian homes — white salty patches climb up ground-floor walls after rain. Normal emulsion paint makes it worse by trapping moisture. The best fix in 2026 is a damp-proof primer + breathable masonry paint system. Here’s the exact method that stops rising damp permanently.
Why normal paint fails on rising damp
- Moisture & salts wick up from the ground through porous paint
- No damp-proof barrier used
- Standard emulsion seals moisture in → bubbling & efflorescence
- Wall not dried & sealed properly first
Step-by-step fix – how to fix rising damp on interior walls in Nigeria
- Stop external water entry – fix guttering, improve drainage, add French drain if needed (critical first step)
- Dry wall completely – fans/dehumidifier 14–28 days depending on severity
- Remove efflorescence & loose plaster – dry brush + vinegar solution
- Apply damp-proof primer – Prestige Timeless Damp-Lock Interior Primer (2–3 thin coats up to ~1 m height)
- Topcoat – Prestige Timeless Breathable Masonry Eggshell or Satin (2 full coats)
- Eggshell for most rooms
- Satin for higher moisture areas
Quick finish recommendations
- Living / bedroom ground floor → Breathable Eggshell
- Kitchen / utility → Breathable Satin
- Severe rising damp history → Damp-Lock Primer + Breathable Satin
Expected result Done correctly + external water fixed, rising damp should not return for 7–12 years.
