Abstract
A method of finishing a concrete structure which comprises coating an aqueous acrylic acid esters resin emulsion including a special acrylic acid esters copolymer on the bare surface of a concrete structure and after dried, forming a cement-based finishing layer. The action of the film formed by said emulsion provides an improved adhesive bond strength between said concrete structure and the finishing layer, prevents breakage of the finishing layer almost permanently, and is, furthermore, effective in bonding the coated layers strongly, even when they are coated repeatedly.
