Loctite 1618150 Sealant, Gray, 10 oz Cartridge

PL® S20 polyurethane self-levelling concrete crack masonry sealant is a professional-grade sealant for concrete. It is a one-component, polyurethane, self-leveling sealant for contraction or expansion joints and cracks in concrete floors and decks. It cures in place to form a highly resilient and abrasion-resistant seal, which resists deterioration caused by weather, stress, movement, traffic and water. Its abrasion and tear resistance makes it ideally suited for applications exposed to pedestrian and vehicular traffic.
