UniBase Primer

Why 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.


  • Products can be brush, roll, or spray applied
  • Meets all VOC emissions and regulations to eliminate facility downtime during installation
  • Easy application and clean-up
  • Excellent asphalt bleed blocker
  • Low toxicity


UniBase Primer can be applied over conventional built-up, granulated cap sheets, mod bit, concrete, and selected previously coated surfaces. It can be used to penetrate and adhere reinforcement fabric, forming a flexible base for applying acrylic finish coats.
