Do You Know Why Paint Bubbles?

Must read

Bubbling of the paint coating on home exteriors is a very common issue noticed in many homes.

Water will just escape from the substrate and evaporate.

In leak detection, leaking windows, and leaks in roof and gutter are the usual suspects. Poor construction techniques, wood end grain left unsealed, seams and vertical joints around the doors and windows which can let rain water enter the substrate can all lead to bubbling in paint job.
