DAIHARD® U30 is a single component water-based urethane floor coating for concrete and masonry surfaces, as well as wood. It can be used on both interior and exterior applications.

1KU is a fast-drying primerless application with rapid recoat times of as little as three hours. It penetrates tenaciously into concrete and once cured, forms a tough water, chemical and wear resistant surface which outperforms most retail other utility floor coatings.

Where additional sheen is desired in the floor finish, one uniform coat of DaiHard® U30 Urethane Clear Coat is recommended for outstanding compatability and long-term performance.
