Homes in Lorne, Anglesea and Torquay face a constant assault from salt air, humidity and harsh coastal sun. Here's how to choose the right marine-grade coatings and schedule repainting so your weatherboard or render home stays protected for longer.
If you live within a few kilometres of the ocean, your paint has a tougher job than homes further inland. The Surf Coast's onshore winds carry fine salt particles that settle on every painted surface. Combined with high humidity and intense UV, this is the perfect recipe for accelerated paint failure.
Salt is hygroscopic — it draws in moisture and holds it against the surface, causing blistering, bubbling and early breakdown of paint films.
Persistent moisture prevents proper curing and encourages mould, mildew and timber rot beneath the paint film.
Coastal sun fades colour and breaks down binders faster. South- and west-facing walls cop the harshest exposure.
Not all paint is created equal for the coast. For Surf Coast homes we specify premium acrylic exterior paints formulated for high salt and UV environments. The key is pairing the right primer with a flexible, breathable topcoat.
For any metal surfaces, fascia, gutters or railings, a specialist anti-corrosion primer is essential before top coating to resist salt-driven rust.
Acrylic paints are flexible, allow the substrate to breathe, and resist cracking as timber expands and contracts with coastal moisture.
Dark colours fade more visibly under coastal UV. Light, earthy coastal palettes not only look the part but stand up better to the sun.
The honest answer: sooner than you'd expect. While inland weatherboard homes can go 10–15 years between repaints, coastal homes typically need attention every 5–8 years depending on exposure. Here's a rough guide.
| Surface | Typical Repaint Interval |
|---|---|
| Weatherboard (protected) | 8–12 years |
| Weatherboard (exposed) | 5–8 years |
| Render / brick | 10–15 years |
| Timber decking | 2–3 years |
