Abstract
A waterborne coating composition comprising a waterborne epoxy coating with hydraulic cement, which is capable of a thin initial application. The coating composition may be made, stored and transported as a two-part composition, where each part is a pourable liquid. The waterborne epoxy composition cures under normal conditions and adheres to surfaces including masonry, concrete and metal.
