Quick answer: In Kenya, exterior walls typically need repainting every 5–8 years, interior living areas every 5–7 years, and high-traffic rooms such as kitchens, corridors and rentals every 2–4 years. Roofs last about 5–7 years, and gates and grills 2–4 years. Preparation and paint quality can halve or double these numbers.
Repainting at the right time protects your walls, roof and metalwork and keeps the value of your property. Wait too long and you pay for extra repairs, such as rust, damp and cracked plaster, on top of the paint.
How long paint lasts on each surface
| Surface | Typical life in Kenya | What shortens it |
|---|---|---|
| Exterior walls (weatherproof acrylic) | 5 – 8 years | Strong sun, driving rain, coastal salt, poor prep |
| Exterior texture coatings | 8 – 10+ years | Cracked plaster, damp |
| Living rooms and bedrooms | 5 – 7 years | Dust, children, cheap paint |
| Kitchens and bathrooms | 3 – 5 years | Steam, grease, poor ventilation |
| Corridors, stairwells, rentals | 2 – 4 years | Heavy traffic, moving furniture |
| Ceilings | 7 – 10 years | Leaks, kitchen smoke |
| Mabati roofs | 5 – 7 years | Rust, skipped primer, heat |
| Metal gates and grills | 2 – 4 years | Rust, rain, no primer |
| Wooden doors and fascia (exterior) | 2 – 3 years | Sun and rain on unprotected wood |
Signs it’s time to repaint
- Chalking: rub the wall and a powdery residue comes off on your hand.
- Fading: the sunny side of the house looks noticeably lighter than the shaded side.
- Peeling, flaking or bubbling paint.
- Hairline cracks in render that can let rain in.
- Mould or algae on shaded walls and in bathrooms.
- Rust on gates, grills or roofs.
- Stains that won’t wash off inside.
- Bare wood on doors, frames and fascia boards.
Why Kenyan conditions are tough on paint
- High UV: on the equator and at altitude, sunlight breaks down cheap paint binders quickly, causing fading and chalking.
- Two rainy seasons: walls get wet and dry twice a year.
- Red dust and murram: it stains light walls and wears interior paint as you clean it.
- Coastal humidity and salt: they speed up mould, rust and peeling in Mombasa, Kilifi and Diani.
When to repaint: the best season
For exteriors and roofs, paint in the dry seasons, roughly January–February and June–September. Fresh paint needs dry hours to cure, and walls need to be dry before painting. Interior painting can be done year-round, though drying is slower on cold, wet days.
Repaint or wait? The cost of delay
Repainting when paint is faded but still intact is the cheapest option: wash, spot-repair and apply two coats. When you wait until it peels, every loose area has to be scraped and primed. Wait until damp, rot or rust sets in, and you also pay for plaster repairs, carpentry or new roofing sheets.
How to make paint last longer
- Use a quality paint made for the surface. See the best paint for exterior walls and best paint for interior walls.
- Insist on proper preparation and a primer.
- Apply two full coats, never watered down.
- Wash exterior walls once a year and clear gutters before the rains.
- Touch up gates and wood as soon as chips appear.
- Fix leaks and cracks quickly.
