ARC 797

Chesterton ARC 797 is a versatile, thin-film composite coating engineered to protect concrete surfaces from chemical attack and abrasion. Its low-viscosity formula enables easy brushing or flow application, delivering a seamless protective layer that resists a wide range of acids, alkalis, and solvents.

Ideal for secondary containment, pipe wrap areas, sumps, and spill zones, ARC 797 bonds strongly to sound concrete and aged overlays, providing durable, long-lasting protection in industrial environments with minimal thickness and application effort.
