Solvent-based All Resin Transparent Concrete Curing Compound

CHEM-CRETE UNIFOUR 30C is a 100% resin-based transparent curing compound of a solution of resinous solids in petroleum solvents with white heat reflective pigments. CHEM-CRETE UNIFOUR 30C 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.


Technical Data Sheet


CHEM-CRETE UNIFOUR 30C can be used for curing fresh concrete to prevent losses of hydration moisture and to prevent formation of cracks.

  • AASHTO-M-148, Type 1, Class A or B
  • Corps of Engineers CRD-C-300 (Reflectance Waived)


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 square feet per gallon (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.


Do not allow material to come into contact with eyes, hands, glass, aluminum or glazed tile systems.


Store all containers between 40ºF and 95ºF (5ºC and 35ºC). Shelf life 1 year in original unopened container.
