Blistering
How to fix blistered paint in Geelong and western Melbourne
The problem
Blistered paint shows up as bubbles or raised patches, and it’s a common issue across Geelong and western Melbourne.
It usually happens when heat or moisture gets trapped under the paint. This can be caused by painting in direct sunlight on a warm surface, applying oil-based or alkyd paint over a damp area, moisture escaping through exterior walls, or fresh paint being exposed to dew, rain or high humidity too soon.
In coastal parts of Geelong, salt air and moisture can worsen the problem. In western Melbourne suburbs, heat and poor surface preparation are often the main cause. Painting over blistered areas will not solve the issue. In most cases, it comes back.
The solution
The right fix depends on how deep the blistering goes.
If the blisters go all the way down to the substrate, the problem is usually moisture. In that case, the source of the moisture needs to be fixed first. This may involve repairing loose caulking, improving ventilation, or addressing leaks before repainting.
If the blistering only affects the top layer of paint, it is more likely caused by heat or poor preparation. The damaged paint should be scraped off, the surface sanded smooth, and any bare timber primed before repainting.
For a longer-lasting result, always allow surfaces to dry properly and use a quality exterior paint suited to local conditions in Geelong and western Melbourne.
