TL;DR
Blistering paint is the defect in which bubbles or domes swell beneath a dried coating, raised by heat or by moisture vapor pushing the film off its substrate. Heat blisters come from painting in direct sun or over a hot surface, trapping solvent; moisture blisters point to wet wood, painting over dew, or vapor escaping a damp wall from inside the house.
What it means
Blistering paint is the defect in which bubbles or domes swell beneath a dried coating, raised by heat or by moisture vapor pushing the film off its substrate. Heat blisters come from painting in direct sun or over a hot surface, trapping solvent; moisture blisters point to wet wood, painting over dew, or vapor escaping a damp wall from inside the house. Diagnosis is in the layers: cut one open, and bare wood underneath means a moisture source while paint underneath suggests a solvent or surface-prep failure. The fix is to remove the source, scrape and sand the damage, prime, and repaint, since repainting over an unsolved cause re-blisters.
