StarSeal EF Cure

STARSEAL EF CURE is part of Vexcon’s complete line of environmentally friendly products designed to protect and improve concrete and masonry while leaving a lower environmental footprint. StarSeal EF Cure is a clear curing compound applied to freshly place concrete surfaces forming a tough, continuous, protective membrane. This membrane acts as a barrier allowing for low moisture transmission and maximum development of the concrete’s strength and wear resistance during concrete’s early hardening stage. The protective film will not discolor the concrete and dissipates as exposed to UV, weather and traffic.
