The invention relates to a composition and method for effectively increasing the hardness of a concrete surface and other cementeous materials. More specifically, increasing hardness of concrete by applying a strontium based solution to its surface, and the structure made by the method. The invention also relates to application of surfactants and/or other additives in order to improve the penetration of the hardening agent into the concrete surface and other cementeous materials, improve the water and/or oil repellant properties of the concrete, and/or improve its stain resistance. |
