SPRAY-PLAST is an interior, high solids, level 5 drywall primer/surfacer, that when applied over a level 4 gypsum wallboard finish achieves a level 5 finish. SPRAY-PLAST in accordance with GA-214/ASTM C-840 gypsum board finish specifications, achieves a level 5 finish, which is the highest quality drywall finish. SPRAY-PLAST is specifically formulated to equalize the porosity difference between the wallboard surface and joint compound, which will allow for final coat(s) of paint to dry at a uniform rate.
