Loctite

Loctite PL polyurethane concrete and masonry sealants for cracks, joints, driveways, sidewalks, garage floors, and exterior concrete gaps that need a flexible, weather-resistant seal. Loctite is part of Henkel Corporation (Professional and Consumer Adhesives, Rocky Hill, Connecticut). Maker literature notes Loctite brand adhesives and sealants have been used for demanding industrial and consumer jobs for over 50 years. This brand collection covers Loctite products currently in the store.

Per Henkel technical data sheets, Loctite PL S10 is a one-component, textured, moisture-curing gun-grade polyurethane sealant for permanent water- and weatherproof seals in exterior concrete and masonry gaps and joints. It is non-sagging, remains flexible after cure, does not require a primer on concrete, brick, stone, or masonry, and is paintable once fully cured (maker states at least 7 days). Loctite PL S20 is a one-component self-leveling polyurethane sealant for contraction/expansion joints and cracks in concrete floors and decks; it needs no tooling, cures to an abrasion-resistant seal suited to pedestrian and vehicular traffic, and is also paintable after full cure. Both lines are sold in gray 10 oz cartridges in this shop.
