A method for retarding the formation of surface cracks on an uncured latex-modified portland cement concrete substrate, comprising:
- (a) contacting the surface of said uncured substrate with a layer of ethylene-vinyl acetate copolymer latex in amounts sufficient to retard the formation of surface cracks on the concrete substrate and prevent water evaporation from the concrete substrate, and
- (b) curing the concrete substrate at atmospheric conditions.
An article of manufacture comprising a latex-modified portland cement concrete substrate having a surface coating of an ethylene-vinyl acetate copolymer latex.
A cover system for retarding the formation of surface cracks on an uncured latex-modified concrete substrate consisting essentially of a layer of ethylene-vinyl acetate copolymer latex coated on a substrate of a latex modified portland cement concrete.
