Weatherproof Neutral Cure Silicone Sealant for Lead Flashings & Roofing Applications

It provides a long-lasting, flexible, and waterproof seal, ideal for use in roofing, cladding, and masonry applications where lead, brick, stone, or concrete meet. This professional-grade sealant remains permanently elastic, resisting UV, weathering, and thermal movement while bonding without primer to most common roofing materials.
