Where to Buy


Loctite® PL® S20 Polyurethane Self-Leveling Concrete Crack Sealant

Loctite® PL® S20 Polyurethane Self-Leveling Concrete Crack Sealant is a professional grade sealant for concrete. It is a one component, polyurethane, self-leveling sealant for contraction / 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.
