Certi-Vex Envio RC 1000

CERTI-VEX ENVIO RC 1000 is a solvent based cold weather clear curing compound. Curing at colder, below freezing temperatures will not effect the performance of the product. During concretes early hardening stage, the products protective film ensures low moisture transmission allowing for maximum development of the concretes strength and wear resistance, producing hard durable concrete. The protective film will not discolor the concrete and dissipates as exposed to light, weather and construction traffic.
