Solution: If you notice paint bubbles after a primer-free paint application, remove the bubbles using the scraping-and-patching technique outlined below, clean the surface of joint compound dust and other debris, then apply a stain-blocking primer to the surface before re-painting it. Either oil-based or latex primer will do; pick yours to match the type of paint you plan to roll on afterward. (If you’re still deciding on the new topcoat, keep in mind that oil-based primer is more resistant to moisture, making it a better choice in high-moisture spaces like bathrooms or kitchens.)
How to prevent paint blisters?

Why does my paint bubble after a paint job?
Extreme heat—common in kitchens, living rooms, and other spaces containing heat-generating appliances or lots of direct sunlight—soon after a fresh paint job can cause the topcoat to dry unevenly at a faster-than-average rate, leading to bubbles just underneath the surface.
What size roller cover should I use for drywall?
When painting a smooth or semi-smooth surface like untextured drywall or plaster that you might find in the kitchen, you’ll want to enlist either a foam or a short nap roller cover (3/16- to ¼-inch nap for smooth or ?- to ½-inch for semi-smooth); this applicator will create minimal gaps with each stroke to aid in optimal paint adhesion. A medium nap roller cover (¾- to 1-inch) is recommended for moderately rough surfaces like stucco, and a long nap roller cover (1-¼- to 1-½-inch) should be saved for extremely rough surfaces like textured drywall.
How to stir paint slowly?
Stir paint slowly. Enlist a wooden stirrer or a paint-mixing power drill attachment to stir paint as slowly and for as short a duration as possible .

How to fix bubbling paint?

When you’re finished, rinse the putty knife with water, dry it with a rag, then use it again to fill any holes or cracks in the substrate with a thin, even layer of quick-setting joint compound. Let the compound dry overnight, then lightly sand the dried compound until smooth with a fine-grit sandpaper.

Why Bubbles Appear In Car Paint
Also known as osmotic blistering, bubbles are the result of moisture entering the paint. During application, droplets get trapped inside or below the paint’s surface.
Is It Rust?
Corrosion also causes paint to start bubbling and experience adhesion issues. Moisture is a culprit here but as an equal factor, the metal below the paint needs to be exposed. This area can be as small as a chip from a rock or as large as a dent from a fender-bender.
When Is It Not Rust?
The rate of application can also create a bubbling effect. Unlike rust or moisture, this occurrence resembles pinholes or craters. Adding too much too soon or standing too close during application ends up trapping solvents or creating air pockets. Solvents will eventually emerge from the outer layer.
