Epoxy Grout

Mix this two-part epoxy—a resin-aggregate blend and a pigmented hardener—to create a grout that resists chemicals, such as acids, alkalies, salt water, and common solvents and cleaners. Its lightweight formula makes this grout easy to spread. Use in horizontal or vertical joints—grout won’t sag or shrink. Apply with a grout float. It can be cleaned up with water when wet; it doesn’t require a sealer once it cures. The size listed is the combined total of the two parts.
