Why Matrix™ 307 Premium Asphalt Primer?

MATRIX™ 307 Premium Asphalt Primer is a general purpose, asbestos-free foundation coating for all types of asphalt-based roofing materials, e.g., hot-mopped or cold-applied asphalt coatings, roof cements, and asphalt-based roof and flooring adhesives. MATRIX™ 307 has an excellent penetration rate that promotes a tough bond for coating and adhesives while providing strength and flexibility to accommodate temperature-related expansion and contraction of the roof system. It is easily applied with a sprayer, brush, or roller.
