How Long Does Exterior Paint Last on a Coastal Home?
Exterior paint should last 10+ years on a coastal home — but only if the prep and system are right. Here's what really drives lifespan.
Realistic lifespan by system
On a properly prepped coastal home, here's what we tell clients to expect — assuming Dulux Weathershield, Wattyl Solagard or Haymes Solashield, two finish coats minimum.
Lifespan by substrate
Substrate matters more than most homeowners realise.
- Rendered masonry — 12–15 years with a quality acrylic
- Fibre-cement (HardiePlank, Scyon) — 10–12 years
- Weatherboard (timber) — 8–10 years, less on north faces
- Bare or chalking metal — 6–8 years without a primer system
- Eaves and soffits (shaded) — 15+ years
What halves the lifespan
Three things consistently halve the life of an exterior paint job in Tweed Heads: skipped pressure-wash, single-coat application, and using interior-grade paint outside. None are obvious from the kerb until year 3 or 4.

How long does exterior paint last — frequently asked questions
- How much does exterior painting cost in Tweed Heads?
- Full exterior repaints in Tweed Heads generally range from $5,000 to $11,000 depending on home size, storeys, cladding type and how much rendering, timber or fibro repair is needed before painting.
- How often should a coastal home be repainted?
- Within a few kilometres of the Tweed Heads coastline, exteriors typically need repainting every 7–10 years — salt air and UV break down films faster than inland. Washing the exterior annually stretches that out.
- What paint do you use on coastal exteriors?
- We specify premium exterior acrylics rated for UV and salt exposure over the correct primer for each substrate, applied in two full coats — not a single thinned coat over the old colour.
- Are you licensed and insured to work in Tweed Heads?
- Yes. Munn & Co. Finishes holds an NSW painting licence and a QLD QBCC licence, and we carry full public liability insurance. Licence and insurance details are supplied in writing with every Tweed Heads quote.
