Industrial Grade Epoxy | Rockhard Pro 3 Gal. Kit

Rockhard Clear Epoxy is a professional-grade, 100% solids-style clear epoxy system engineered for concrete floors that require a durable, seamless, high-gloss finish. Its transparent formula is ideal for enhancing decorative concrete, metallic epoxy designs, color flakes, quartz systems, broadcast media, and other custom interior floor designs without hiding the underlying appearance.

The two-component formula provides excellent adhesion and durability while helping protect concrete from everyday wear, dusting, and chemical exposure. With a theoretical coverage rate of approximately 100 sq. ft. per gallon at a 16-mil dry-film thickness, Rockhard Clear Epoxy is suited for building substantial film thickness in a single application.

Its solvent-free formulation requires no standard thinning, and the product can be used as a clear mid-coat within a complete epoxy flooring system. For projects requiring added UV stability, abrasion resistance, or long-term gloss retention, it can be top-coated with a compatible urethane or polyaspartic coating.
