Repaint cycles in the WA climate
How often to repaint, by surface
Realistic intervals for Perth homes with a quality system over sound preparation. Harsh exposure shortens them.
| Surface | Typical repaint interval | Sooner if… |
|---|---|---|
| Interior walls | 7–10 years | High-traffic areas, kids’ rooms, rentals |
| Hallways & high-traffic | 5–7 years | Marks, scuffs and knocks |
| Exterior render / masonry | 8–12 years | North and west walls, coastal suburbs |
| Exterior timber & weatherboard | 5–8 years | Full sun, movement, moisture |
| Trims, doors & fascias | 4–7 years | Sun exposure, wear |
| Roof coating | 10–15 years | Heavy UV, previous coating failing |
What shortens the interval in Perth
UV exposure
Perth’s intense sun fades pigments and chalks binders. North and west elevations age fastest.
Coastal salt
In suburbs like Cottesloe, Scarborough and Fremantle, airborne salt attacks coatings and accelerates wear.
Colour choice
Deep, dark colours absorb more heat and fade faster than light, reflective tones on sun-facing walls.
Substrate & movement
Timber and fibre-cement move with heat and moisture, stressing the film more than solid render.
Paint quality
Budget paint over thin prep can fail in a few years; a premium UV-stable system lasts the full cycle.
Preparation
How well the last job was prepped sets how long this coat lasts. Shortcuts shorten the interval.
Signs it’s time to repaint
- Fading or patchy colour, especially on north and west walls
- Chalking – a powdery film that rubs off on your hand
- Flaking, peeling or blistering paint
- Cracking or gaps opening at joins and around windows
- Exposed filler or bare timber showing through
- Mould or staining on shaded, south-facing walls
How to make a repaint last longer
- Use a premium UV-stable system matched to the substrate (see best paint for the WA sun).
- Don’t skip prep – washing, sanding, sealing and priming are what make it last.
- Wash exterior walls yearly to remove salt, dust and grime.
- Touch up early – small fixes to trims and sun-facing walls delay a full repaint.
