Why GAF UniBase Primer?
UniBase Primer is designed to enhance the adhesion of Roof Mate™ top coats or the PremiumCoat System over approved surfaces, and as a saturant for fabric reinforcement applications. UniBase Primer also acts as an excellent asphalt bleed blocker. Unibase Primer is an easy-to-apply, cost-effective method of securing reinforcing fabric over surfaces prone to structural movement, allowing the stress to be distributed over a broader area of the roof coating system.
It helps block the migration of asphaltic oils, so the United Coatings™ Roof Mate™ coating can reduce the risk of bleed-through problems often associated with conventional roof-coating systems.
