A dry method of concrete floor or concrete surface restoration uses the process of grinding a concrete surface to be resurfaced while extracting and retaining dust during the grinding process. The grinding process is repeated each time using finer grinding grit until a preselected degree of smoothness of the concrete surface is achieved. A sealer is applied to the concrete surface which has been ground to the predetermined degree of smoothness. In a preferred embodiment, two coats of sealer are applied and the sealer is preferably a water-based, odorless, penetrating alkaline siliconate solution. The method of the present invention limits down time to aisles and main areas during the restoration process, as well as limiting the dust and odor during the process to provide a lustrous smooth surface on the concrete.
