Exterior and interior painting is one of the most effective ways to protect and add value to your property. But in Wellington's demanding coastal environment, preparation and paint chemistry make all the difference.
🎨 The Golden Rule of Painting
80% of a flawless, weather-tight paint finish comes from mechanical sanding, gap filling, and primer adhesion. Never apply topcoats over peeling or chalky surfaces.
1. Selecting Weather-Tough Exterior Systems
Wellington homes face intense UV, salt air, and high-velocity wind-driven rain. We recommend high-performance 100% acrylic systems such as Resene Lumbersider or Dulux Weathershield, which expand and contract with seasonal timber movement without cracking or blistering.
2. Proper Surface Preparation Steps
A durable exterior repaint requires methodical prep:
- Soft Washing: Neutralize mould spores and airborne salt deposits using biodegradable house wash.
- Lead-Safe Scraping & Sanding: Feather all paint edges down to sound timber using HEPA dust extraction.
- Sealing & Priming: Spot-prime bare timber with alkyd or waterborne wood primers before filling nail holes with epoxy filler.
- Two Heavy Topcoats: Apply full-coverage coats maintaining wet edges for maximum film thickness and sheen uniformity.
“A properly prepped and applied premium paint system will reliably protect your weatherboards for 10 to 12 years between major repaints.”
