USES
CHEM-CRETE UNIFOUR 30C can be used for curing fresh concrete to prevent losses of hydration moisture and to prevent formation of cracks.
CHEM-CRETE UNIFOUR 40
Solvent-based All Resin White Pigmented Concrete Curing Compound
CHEM-CRETE UNIFOUR 40 is a 100% resin-based curing compound of a solution of resinous solids in petroleum solvents with white heat reflective pigments. CHEM-CRETE UNIFOUR 40 will form a film on a concrete assembly which will eventually dissipate after the critical intermediate curing stage is completed. Will allow subsequent applications of materials such as: paint, epoxy, mastic, etc. Product is used primarily on engineering projects such as highways, airport runways, and other concrete assemblies exposed to direct sunlight.

APPLICATION
Preparation: as soon as the concrete assembly has reached the set stage and the finishing is completed, make sure the surfaces of the concrete assembly are free from ponded water and proceed to application.
Application: thoroughly agitate materials immediately prior to use. Decant materials into a handpump spray can, liquid tank for power spray equipment or install drum pump directly to material container. Spray CHEM-CRETE UNIFOUR 30C in a consistent pattern at a rate of 200 Ft2/Gal (4.9m2/L) over the entire surface area of the concrete assembly in the shortest amount of time possible.
Cleaning: clean all tools and sprayers with Mineral Spirit.
STORAGE
Store all containers between 40ºF and 95ºF (5ºC and 35ºC). Shelf life 1 year in original unopened container.
SAFETY
Do not allow material to come into contact with eyes, hands, glass, aluminum or glazed tile systems.
