1618522 Pl S10 Concrete Crack Polyurethane Sealant, 10 Oz. Cartridge

Loctite PL S10 is a one-component, moisture-curing polyurethane sealant engineered to create permanent, water and weatherproof seals in exterior gaps and joints in concrete and masonry. This commercial-grade, non-sagging formula is ideal for repairing cracks in vertical and horizontal surfaces such as concrete walls, foundations, brick, and block walls, as well as sealing expansion joints where flexibility matters.

The sealant remains elastic and flexible after curing, expanding and contracting with construction material movement to maintain the integrity of the seal over time. Its texturized appearance blends naturally with masonry substrates for a finished look. Unlike some polyurethane sealants, PL S10 requires no primer when applied to concrete, brick, stone, or masonry surfaces, saving time on preparation. The formula is paintable and complies with low-VOC requirements, making it safe for indoor and outdoor applications.
