    • An aqueous coating composition for coating concrete-like materials to prevent loss of water vapor during hardening. The aqueous coating composition comprises 5.0-45.0% by weight of a wax or wax-like material, 1.0-10.0% by weight of polyvinyl alcohol, 0-1.0% by weight of a biocide and the balance of water. Also disclosed is a method of coating a concrete-like material including the step of applying, to the surface of the concrete-like material a coating of the aqueous coating composition of the invention. Also disclosed is an article of manufacture which includes a concrete-like material having applied thereto a coating as described above. The aqueous coating composition surprisingly meets the relevant ASTM and other standards for concrete curing without employing any hazardous materials and/or volatile organic compounds.
