UniBase Primer is a low viscosity, highly penetrating, advanced acrylic polymer adhesive and primer that develops a tenacious bond to existing rough/textured roof substrates. Designed to act as a bonding primer to enhance the adhesion of the PremiumCoat® System over granulated cap sheets / modified bitumen roofing, UniBase also acts as an excellent asphalt bleed blocker. UniBase is an easy to apply, cost effective method of locking down residual dust, granules, or contamination from granulated substrates, thereby maximizing adhesion of the PremiumCoat® System.
