Self-leveling Concrete Joint Sealant




Precision Seal SL is a single-component, polyurethane hybrid, self-levelling sealant designed to offer superior adhesion to concrete. Ideal for sealing cracks and joints in driveways, patios, pool decks, porches and sidewalks. It remains flexible for the life of the sealant, between 5-7 years after cure. This low-modulus, moisture-cure sealant is formulated to be extremely durable in dynamic joints and provides superior wear resistance in high traffic areas.
