Cheap or interior paints are not designed to handle heavy rainfall, humidity, or UV rays. They quickly peel, blister, or allow mould to grow underneath.
Best Types of Exterior Paint to Resist Mould and Algae
Not all paints are equal — and in The Gambia’s climate, choosing the wrong paint can actually trap moisture and make mould problems worse.
Why Ordinary Paint Fails
Look for Mould-Resistant Paints
Exterior-grade paints often contain anti-fungal additives that resist mould and algae growth. This makes them ideal for homes near the coast or areas with lots of vegetation.
Breathability Matters
Walls need to “breathe.” If paint is too waterproof and not vapor-permeable, trapped moisture inside the wall will cause bubbling and peeling. The best paints allow water vapor to escape while still repelling rain.
Long-Term Savings
Though high-quality paints cost more, they last longer and reduce maintenance costs. Repainting every 8–10 years is much cheaper than repairing damaged plaster or mouldy walls every 3–4 years.

Practical Tip
Choose a light colour — it reflects heat, keeps walls cooler, and reduces thermal stress that causes cracks.
