The UGL 30507 is a masonry crack filler designed to seal and waterproof cracks in concrete sidewalks, walls, steps, and floors. It also replaces cracked mortar joints, making it a versatile repair solution for both interior and exterior masonry surfaces. The filler adheres to damp surfaces, dries to the color of concrete, and will not bleed after application. Each 10.5-ounce cartridge yields 48 linear feet per 1/4-inch bead. Licensed trade contractors and experienced DIYers use this product to address structural crack repairs and moisture intrusion points in concrete and masonry assemblies.
This filler suits a wide range of masonry repair applications in both residential and light commercial settings. It is appropriate for use on poured concrete, block, and mortar joints exposed to weather or below-grade moisture. Because it adheres to damp surfaces and reduces radon gas penetration, it is well suited for basement walls, foundation repairs, and exterior flatwork including steps and sidewalks. The product is non-flammable and cleans up with water, making jobsite handling straightforward.
Designed for use on concrete sidewalks, walls, steps, floors, and cracked mortar joints in interior and exterior masonry applications.
Application is appropriate for general contractors, masonry trades, and qualified property maintenance professionals. Surfaces should be clean and free of loose debris before application, though the product will bond to damp substrates. Allow a full 12-hour cure time before exposing the repair to traffic or moisture. If painting, use latex-based coatings applied immediately after the filler is set.
