A composition composed of an aqueous mixture of at least one first copolymer, a method for inhibiting moisture vapor emission from the surface of a concrete structure and accentuating interfacial adhesion between a concrete surface and a covering thereon, and a method for inhibiting loss. of water from a cured or partially cured concrete structure

摘要

The present invention is directed to a composition capable of inhibiting moisture vapor emission from concrete structures and enhancing adhesion of a finish material to the concrete structure comprising an aqueous mixture of a first copolymer of mer units formed from vinylidene halide and a C1-C2 alkyl acrylate with a second copolymer of mer units formed from vinylidene halide and a C4-CS alkyl acrylate and to the method of forming a moisture barrier/adhesion promoter coating on concrete comprising applying from 2.8 to 5.6 liters (0.75 to 1.5 gallons) of an aqueous carrier having from 10 to 50 weight percent of the mixture of copolymers stated above per 14 m2 (150 square feet) of the free surface of a concrete structure.
