CURESHIELD EX is a unique solvent based blend of silane and pure acrylic copolymers designed to cure and seal fresh concrete and provide additional protection to existing concrete. CURESHIELD EX provides a non yellowing, clear film which effectively cures and protects fresh concrete. In addition to forming an effective film forming curing and sealing compound, it also contains silane. Silane penetrates the fresh concrete and provides protection against spalling and deterioration of concrete structures caused by deicing salts. CURESHIELD EX can be applied to fresh concrete unlike other siloxane, silane type products and also meets ASTM C-309 and 1315 curing standards. CURESHIELD EX penetrates the surface and bonds directly with the substrate, which results in a surface that is highly resistant to moisture and salt.
