Ready-to-Use Evaporation Retardant

EUCOBAR RTU is a ready-to-use evaporation retardant for use on concrete surfaces of all types. When sprayed over fresh concrete, EUCOBAR RTU forms a monomolecular film that prevents rapid moisture loss from the concrete surface. EUCOBAR RTU is especially effective when concreting operations must be performed in direct sun, wind, high temperatures, or low relative humidity. EUCOBAR RTU is supplied pre-diluted, and does not require the addition of water before using.
