ROCEpoxy® Direct-to-Metal Epoxy Mastic 9100 is a two-component, high solids epoxy coating engineered for outstanding durability in industrial environments. Designed to simplify application without compromising performance, it offers excellent resistance to abrasion, chemicals, solvents, and impact—making it ideal for high-demand surfaces.

This epoxy can be applied directly to sound rusted steel, galvanized metal, clean steel, concrete, and even slightly damp surfaces, eliminating the need for multiple products. With a user-friendly 1:1 mix ratio and a generous two-hour pot life, it’s optimized for professional ease and flexibility. Multiple activator options allow tailoring for specific needs: Fast Cure, Low Temp, Immersion, Satin Finish, and Standard. Available in two VOC versions (340 VOC and 250 VOC), it also works effectively as a primer beneath Rust-Oleum ROCThane high-performance topcoats.
