Paint is bubbling and cracking while still wet. Paint is Behr latex gloss enamel on a metal door prepared with grabber primer. Is there a solution for this happening?
2 possible causes;
1- Door is hot while painting. Paint could bubble or blister when applied to a hot surface. Paint the door when it is cool to the touch.
2- A reaction with the primer. Reprime with another type, example- use an oil base instead of an acrylic.
If the problem persists use a different paint. It could be the Behr paint.
