How to Avoid Bubbling Paint in Auckland’s Coastal Homes
If you live in Auckland’s coastal suburbs, you’ve probably noticed that paint doesn’t always last as long as it should. One of the most common problems we see is bubbling paint — small blisters that form under the surface and eventually peel.
Here’s why it happens and how to avoid it.
Why Paint Bubbles in Coastal Homes
Salt air: Salt deposits draw in moisture, pushing paint off the surface.
Moisture trapped under paint: Poor prep or painting damp surfaces leads to bubbling.
Wrong paint type: Using low-quality or non-exterior paint on weatherboards or roofs.
Sun exposure: North-facing walls in Auckland take a hammering from UV rays.
How to Prevent Bubbling Paint
Thorough Cleaning – Wash exteriors regularly to remove salt and dirt.
Proper Prep – Scrape, sand, and fully dry surfaces before painting.
Use the Right Paint – Premium, weather-resistant paints designed for coastal conditions.
Apply Correctly – Avoid painting in direct sunlight or high humidity.
Regular Maintenance – Rinse exteriors annually to extend lifespan.
