The Ultimate Guide to Sealing Natural Stone: Preserve Beauty and Strength
For a contractor-grade crack filler that can be used on a variety of surfaces and for structures that are frequently exposed to water, consider this epoxy concrete repair product. It dries to a tough, concrete-gray color and withstands water, ice, oil, gasoline, salt, and other contaminants without peeling or cracking. It’s perfect for repairing concrete garage floors, sidewalks, driveways, and walls as well as masonry walls and mortar joints.
This kit comes with everything you need to fill a structural crack that goes through the entire concrete slab (versus surface cracks or cracks that go from joint to joint). It takes about 10 minutes to prepare the injection ports, mix the ingredients, and inject the polyurethane foam into the crack. It expands to fill the entire crack and remains slightly flexible, so soil heaving or vehicle traffic won’t cause it to loosen or pull away from the concrete.
