Abstract
A method for treating a surface of inorganic flooring (e.g., concrete, terrazzo, or a ceramic) includes applying a composition that includes a silicate to a surface of the inorganic flooring and, while the composition is present on the surface, polishing the surface. The silicate may be a lithium polysilicate and/or a colloidal silica. The composition may further include a surfactant and/or a leveling agent. When the composition is applied to the surface of the inorganic flooring, gravity may enable it to spread substantially evenly across the surface. The acts of applying and polishing may be repeated. Such a treatment may result in a surface that has a glossiness that reflects at least about 80% of incident light when the incident light is directed toward the composition at an angle of 60° to the surface.
