Why is my second coat of paint bubbling?
Excess moisture on your painted walls—whether from water droplets, high humidity, leaks, or plumbing problems—can cause water-filled bubbles in the paint, originating anywhere from the substrate level to between the top two coats. Once you’ve remedied the problem, scrape, patch, clean, and dry the walls.
What does blistered paint mean?
“Blistering” is the formation of “bubbles” in the exterior decorative paint film, resulting from localised loss of adhesion and subsequent lifting of the existing paint film from the underlying surface. The loss of adhesion and blistering can quickly lead to paint flaking and peeling.

Why are there tiny bubbles in my paint?
Excessive brushing or rolling – applying a paint too rapidly – will drive excess air into the film. Applying a gloss or semi-gloss paint over a porous or unsealed surface. High heat during application speeds up drying; bubbles or craters that form will dry before they can break and level out.
