Why is my paint peeling or bubbling?
Peeling and bubbling paint is usually a symptom. Moisture behind the paint, poor preparation, or paint applied over dirt or gloss are common causes, and repainting without fixing the cause will fail again.
Safety classification
Safe inspection only
This guide covers safe first actions only. It is not a licence to perform regulated work or enter a dangerous area.
What to do
- 1
Note where it is happening
Bathrooms, laundries, ceilings under wet areas and exterior walls facing weather are the usual places. The location points to the cause.
- 2
Check for moisture
Look for leaks, condensation, water stains, soft plaster or mould nearby. A persistent damp area needs the source fixed first.
- 3
Press a blister gently
If water comes out or the plaster underneath is soft, the problem is moisture, not the paint.
- 4
Look at the surface underneath
Chalky, glossy or dirty surfaces under the peeling layer suggest poor preparation or incompatible paint.
- 5
Get the cause fixed before repainting
A painter can prepare and repaint the surface; a plumber, roofer or waterproofer may be needed first.
When to stop
- The ceiling is sagging or stained
- Plaster crumbles or feels soft
- Water is near electrical fittings
- The home was built before 1970 and paint is flaking
