Is plasprime wayerproof ?

Hey guys, anybody that uses plasprime for skimming know if it's waterproof, been using Feb blue grit primer and Cementone and have noticed is re-emulsifies when wet, had some small issues where the grit bubbles underneath too.

Grit doesn't bet is whatever your grit is on is bubbling up and coming away from the substrate and not the grit itself.
