Master Seal SL1

MasterSeal SL 1 (previously Sonolastic SL 1) is a single-component, non-priming, elastomeric polyurethane sealant formulated for self-leveling application in expansion joints of concrete floors and decks. It is ideal for horizontal interior and exterior expansion and control joints, pavers, plaza decks, industrial floors, driveways, garages, sidewalks, decks, parking structures, and pitch pans. With a movement capability of ±35%, it accommodates joint expansion and contraction, while its abrasion resistance ensures durability. Easy to apply without priming on most surfaces, this sealant requires no tooling due to its self-leveling properties.
