Peeling exterior paint after rainy season is one of the most common complaints in Nigeria. The problem is rarely the colour — it’s usually wrong primer, incompatible layers, or skipping key prep steps. Here’s exactly what to look for in 2026 so your exterior paint survives 5–8 rainy seasons.
Must-have features in 2026 exterior paint
- Alkali-resistant primer (mandatory on new plaster/concrete) Prestige Alkali-Seal Primer — stops paint lifting from high-pH surfaces
- 100% acrylic or 100% polyurethane base These stay flexible when concrete expands/contracts — cement-based emulsions crack
- Documented ≥ Class 1 scrub resistance + ≥ 5-year weather warranty Prestige WeatherShield line carries both
- Built-in fungicide & algae inhibitor Critical in Lagos, PH, Calabar, Uyo
- Minimum 50% volume solids Thicker film = better protection (avoid “economy” paints < 35%)
Red flags that almost guarantee peeling
- “One coat covers” claims
- No primer recommended
- Price below ₦18,000–20,000 for 20 L good-quality exterior
- “100% waterproof” without breathability mention
- No batch number / manufacturing date on bucket
Quick prep cheat sheet (don’t skip these)
- Pressure wash + bleach mildew
- Scrape all loose/flaking paint
- 2 coats alkali-resistant primer
- 2 full top coats (never 1)
