SeamerMate Gutter Sealant functions as an adhesive and/or sealant that develops bonds to most common substrates without the use of a primer. This product is designed for use in leak repairs or installations on gutters, under decks, patio covers, and carports. It provides a permanent seal for installing or repairing rain-carrying systems. SeamerMate Sealant is a non-corrosive, polyurethane single component silicone coating and encapsulating compound. This ready-to-use, single-component compound is high-solid, low-odor material, which cures to a low-modulus, flexible and durable rubber-like solid. The sealant is compatible with most types of metal-to-metal sealing. SeamerMate is also permanently flexible and is mildew and moisture-resistant.
