Rock-Tred Chem-Rock LT-45 is a specially formulated, 100% solids acrylated epoxy system designed to provide positive cure down to 35ºF and extremely rapid room temperature cure. Its low viscosity contributes to easy handling, excellent substrate wetting, and the development of strong bonds to a variety of substrates, including damp concrete.
Rock-Tred Chem-Rock LT-45 was developed for use in cold-weather exterior concrete repair and refrigerated industrial areas where conventional epoxy systems cannot cure completely or cure too slowly to be of practical use to the coatings contractor.

What's the difference between epoxy and urethane coatings, and how do I know which one I need?
Epoxy coatings excel in heavy-traffic, chemical-exposed environments and bond exceptionally well to concrete, steel, and wood. Urethane coatings handle thermal shock and temperature swings better — making them the preferred choice in food processing, commercial kitchens, and freeze-thaw environments. When in doubt, call us — we'll point you in the right direction.
Can these coatings be applied to damp surfaces?
Our cementitious urethane systems are specifically designed to tolerate damp substrates during installation. Epoxy systems vary — some require dry surfaces, others can be applied to damp concrete. We'll spec the right product for your actual job site conditions.
Are your coatings compliant with USDA/FDA requirements for food facilities?
Yes. Our Thermostable urethane coating system meets all USDA/FDA guidelines for use in federally inspected facilities and carries no VOCs, making it a safe and compliant choice for food and beverage operations.
