Is plasprime wayerproof ?

#1
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.

Like i said no problems when using Pva inside or out side.:)

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

Good preparation is more than just chucking a load of pre grit on a wall . Basics Basics Basics...:coffe:
