Sakrete 65450008 Self-leveling Sealant Caulk 10.3 Oz

Product Description

The SAKRETE OF NORTH AMERICA 65450008 is a single-component polyurethane self-leveling sealant caulk designed to seal and repair cracks in horizontal concrete and masonry surfaces. Dispensed from a 10.3 oz tube, this 1-component formula flows into cracks under gravity, forming a flexible, watertight joint with strong adhesion to cementitious substrates. The self-leveling characteristic eliminates the need for tooling on flat applications, making it a practical choice for contractors and masons handling flatwork repairs on job sites or residential properties.

This sealant is suited for horizontal crack repair on concrete walks, driveways, foundations, steps, and masonry block or brick surfaces. Its flowable consistency makes it specifically intended for flat and low-slope surfaces where gravity assists joint filling. It is not recommended for vertical or overhead applications where a non-sag formula would be required. Masonry contractors, concrete finishers, and experienced DIYers use this product for routine maintenance sealing work.
