Henry PR300070 Plastic Roof Cement is a professional-grade mastic compound engineered for high-performance roof repairs and waterproofing. Formulated with a blend of petroleum asphalt and mineral fillers, this heavy-bodied sealant provides exceptional resistance to weathering while remaining easy to apply with a trowel or putty knife. It is specifically designed for patching leaks in asphalt, metal, and composition roofing, as well as sealing around flashings, chimneys, and vents. The material sets firmly shortly after application but retains its pliability over several years to accommodate structural expansion and contraction. This 4.75-gallon pail is ideal for large-scale commercial maintenance and emergency repair projects requiring a durable, water-resistant seal.
