Eucon CSR

Concrete Surface Retarder 

EUCON CSR is based on chemical compositions that delay, but not "kill," the set of mortar at the concrete surface. The retarded mortar surface can be rinsed off with a spray of water once the underlying concrete has cured. Because these compounds do not "kill" the set, if they are left on the concrete or unintentionally splashed over other freshly laid concrete,  they will permit the concrete to eventually attain a set.
