Rust-Oleum Concrete Patch & Repair Kit makes it easy to fix concrete cracks and holes with a durable, industrial-strength epoxy. This two-part formula permanently bonds to concrete, creating a surface that is even stronger than the material. It effectively fills cracks up to 1/2 inch deep and dries to a hard, paintable finish in just 8 hours. The kit features easy mixing, low odor, and contains no solvents, making it convenient and safe to use both indoors and outdoors. Included in the kit are an 8 fl. oz. activator and a 16 fl. oz. base, providing approximately 14 linear feet of coverage. Cleanup is simple with xylene or acetone, and the product has a shelf life of 5 years. This gray, two-component epoxy-based compound is packaged in a box for easy storage and handling.
