Lithochrome Colorwax is a two-component system for curing exterior concrete colored with Chromix admixtures or Lithochrome color hardener. This curing membrane complies with air quality regulations, enhances color development, and retains moisture throughout the entire curing cycle. Concrete strength and abrasion resistance are increased while the surface is protected and staining is reduced. L.M. Scofield Co. 800-800-9900.
