This happens very infrequently. However when you notice this action taking place it means that you are applying the product too heavily. To prevent this "solvent popping" from happening please apply the product in light coats holding the can at least 12" from the surface. Allow each coat to flash off (about 20 seconds) and gradually build it up.
As these products are rubber and synthetic rubber based. A thick coating is NOT required.
Two or three light coats is much better than one heavy coat.
