Product Information

Armor-Hard Extreme is a 100% solids, two-component, low-odor, fast-set structural epoxy/epoxy mortar kit intended for use in the structural repair or joints, cracks, and other surface defects in industrial concrete floors. Armor-Hard Extreme provides superior impact and wear resistance.


Concrete floors in industrial environments are typically subject to extreme traffic from heavy wheeled carts and machinery. Armor-Hard Extreme’s fast-set chemistry allows for quick return to service. Treated floors are ready for foot traffic in one (1) hour and normal in as little as two (2) hours.


Armor-Hard Extreme can be installed in temperatures as low as 20ºF (-7ºC) to as high as +120°F (49°C), giving this product a wider application range than competing structural epoxies.


This kit includes a specially engineered aggregate blend designed for easy troweling/finishing.


USDA/FDA/LEED acceptable.
