High moisture emission concrete floor covering and method

Abstract

A method for applying a high moisture permeability floor covering material to a concrete surface and product thereof. The method comprises the steps of first applying a layer of inert fibers to the concrete surface. To the fiber layer is applied an aqueous acrylate polymer emulsion to form localized bonding penetrations of the emulsion through the layer of fibers to the concrete surface and to form a continuous coating of emulsion on the upper surface of the layer of fibers. The coating is applied so that the coated fiber layer has interconnected moisture transmission passageways communicating with the concrete surface and extending throughout the fiber layer for redistributive diffusion under the continuous coating of moisture vapor from high emission surfaces of the concrete to lower emission surfaces of the concrete. A further layer of high viscosity aqueous acrylate polymer emulsion is applied to said continuous coating and set. A floor covering adhesive and floor covering sheet or tiles can then be applied to the set emulsion surface.
