What Causes Paint to Blister & Peel? How to Fix Bubbles in Paint
Why Does Paint Blister and Peel?
Paint blistering and peeling often occur due to moisture buildup. The expansion of steam weakens the paint's adhesion, causing bubbles to form. Common culprits include:
- Indoor moisture from kitchens and bathrooms
- Outdoor moisture seeping into untreated wood or exposed areas
- Applying paint on wet, dirty, hot, or oily surfaces
- Using oil-based paint over latex paint without priming
- Moisture in foundations or termite infestations
- Improper surface preparation
How to Fix Paint Blisters and Peeling
The only way to fix blistered or peeled paint is to sand the affected area, clean it thoroughly, and repaint. The original paint didn't adhere properly, so repainting is necessary.
Pro Tip: Proper Preparation is Key
To prevent paint blisters, cracks, and peeling, proper surface preparation is crucial. Always:
- Sand and clean walls thoroughly
- Inspect for water damage, leaks, and contaminants
- Use high-quality paint and hire experienced contractors
With the right preparation, you can avoid costly touch-ups and achieve a long-lasting, flawless paint job.
