Marco’s Weather-Tite Metal Roof Sealant


Marco’s Weather-Tite™ Metal Roof Sealant is specifically formulated to outperform other sealant technologies, including silicones, tri-polymers, and polyurethanes. In fact, recent tests against competitive products showed it to have minimal shrinkage compared to solvent-based products, high tensile strength, faster skin cure times, less dirt pickup, and low to no odor. Tests also revealed no cracking, splitting, yellowing, or adhesion failures. That’s because the paintable, UV-resistant MS-Polymer formula will expand and contract with the change of weather and temperature, extruding in extreme weather conditions (down to 0º F). This no-crack performance makes it the ideal choice for exterior applications and damp surfaces. Available in a variety of colors to match today’s popular metal roof and siding colors, it provides exceptional adhesion to Kynar and Hylar 5000, Galvalume, coated and uncoated metal surfaces, plastics, glass, PVC, masonry, stucco, wall panels, vinyl, wood, brass and other common building substrates.
