Methods for enhancing the deicing properties of a cementitious substrate using a polymer-based coating are provided. Coating formulations and coated cementitious surfaces are also provided. The methods comprise applying an aqueous emulsion to a surface of the cementitious substrate and allowing the aqueous emulsion to dry, such that a continuous, fluorine-containing, polymeric coating is formed over the surface of the cementitious substrate. When applied to a cementitious surface, the coating penetrates into the underlying cementitious substrate and bonds with the substrate to provide the cementitious surface with hydrophobic and other properties that improve the deicing properties of the surface. |
