Why Is My Wall Paint Bubbling?

Bubbling in wall paint is a common problem that can occur with both interior and exterior paint. Paint bubbles happen when moisture gets trapped beneath the paint, causing it to lift up and away from the wall. This problem can be caused by many sources, including high humidity, poor surface preparation, and moisture from within the division. When bubbling occurs, it’s essential to address the issue as soon as possible to prevent further damage from occurring.

If the humidity levels remain high, the bubbling will continue to worsen. The only way to stop the bubbling is to reduce the humidity and allow the paint to dry correctly.

Another cause of bubbling paint is poor surface preparation. Before painting, it’s important to ensure the surface is cleaned and free of dirt and dust. Any particles left behind can cause moisture to be trapped beneath the paint, resulting in bubbling.
