Abstract:
1. A method of treating hard surface, comprising the steps of: (a) preparing a composition, wherein said composition comprises a liquid silica sol, wherein the solid content of Si02 is 51%˜99.9% by total solid weight of said composition, at least one of a solid inorganic gel having nano-scale layered, nano-scale chained, nano-scale layered and chained, and nano-scale framework structure, wherein the weight of which is 0.1%˜49% by total weight of said composition, a dispersing medium for dispersing said solid inorganic gel and adjusting solid components of a dispersion of said composition, wherein the weight of which is 1%˜50% by total solid weight, wherein said dispersing medium comprises at least one of a solution with pH value of 3˜11, a weak acid aqueous solution, a weak alkali aqueous solution, water, and softened water; (b) applying and polishing said composition directly onto said hard surface such that said composition is coated onto said hard surface, thereby micropores and scrapes of said hard surface are filled and repaired by said composition and a coating with nano-thickness is formed on said hard surface, and a friction coefficient of at least 0.65 is provided through the coating, wherein said hard surface is selected from the group consisting of granite, polished ceramic tile, marble and terrazzo.
