Introduction
Has your home just been flooded, and now the walls are peeling, mouldy, or musty?
Floods can damage not only the structure but also the aesthetics of your home — especially the walls. This is increasingly common in Malaysia, especially after Tropical Storm Senyar struck in November 2025, causing severe flash floods in Selangor, Perak, and Johor.
This article will help you understand the correct method of repainting after a flood, key preparation steps, and estimated costs to restore your home’s appearance and comfort.'
Why Repainting After a Flood is Necessary
🎨 Prevent Mould & Bacteria – Floodwater leaves behind high moisture
🧱 Restore Wall Structure – Fresh paint helps protect surfaces
🏠 Bring Back Aesthetics – Faded or damaged colours need refreshing
🌬️ Reduce Musty Smell – Anti-bacterial & odour-resistant paints are highly recommended
Studies show that post-flood moisture can remain in walls for up to 3 weeks without proper ventilation.
Initial Steps Before Repainting
Dry the Walls Completely
Use fans, blowers, or keep windows open 24/7 for 7–14 days
Clean Mould & Mud Residue
Scrub using specialised soap or bleach if needed
Scrape Off Peeling Paint
Use a scraper and sand the surface for a smooth base
Apply Undercoat or Sealer
This is essential to ensure the new paint adheres and lasts
Best Paint Types to Use After a Flood
Anti-Mould & Anti-Bacterial Paints Examples: Nippon Vinilex Fresh, Dulux EasyClean
Waterproof Paints Examples: Jotun Jotashield, TOA Moisture Guard
Silicone-Based or Epoxy Paints Ideal for bathrooms and kitchens
Use reputable brands like Nippon, Dulux, Jotun, and TOA for long-lasting results.
Colour Tips for Flood-Affected Homes
🎨 Off-White / Neutral Tones – Makes space look clean & bright
🌿 Sage or Olive Green – Calm, natural tones
🔘 Light Grey / Pastels – Modern and easy to match with furniture
Avoid dark colours as they may highlight any moisture stains.
