Abstract
Systems and methods for treating concrete, which includes the steps of wetting a surface of concrete with colloidal silica, allowing time for the colloidal silica to penetrate the concrete surface, and cutting the surface of the concrete with a bladed or segmented tool wherein the longitudinal blade or edge portion is positioned approximately at an angle between 30 degrees and 90 degrees relative to the surface of the concrete.
Claims19
A tool for finishing or refinishing a concrete surface, the tool comprising:
- at least one tooling element projecting from the tool, the tooling element having a front edge, a rear edge, an inner edge, an outer edge, and a top surface, the front edge being angled between 75 and 85 degrees relative to the concrete surface, the rear edge being angled between 30 and 50 degrees relative to the concrete surface, wherein when the tool is rotated in a first direction such that the front edge is a leading edge, the tool removes material from the concrete surface, and wherein when the tool is rotated in a second direction opposite the first direction such that the rear edge is a leading edge, the tool polishes the concrete surface.
A method for finishing or refinishing a concrete surface, the method comprising:
- installing at least one tool onto a respective tool mount of a drive mechanism of a machine, the tool comprising at least one tooling element projecting from the tool, the tooling element having a front edge, a rear edge, an inner edge, an outer edge, and a top surface, the front edge being angled between 75 and 85 degrees relative to the concrete surface, the rear edge being angled between 30 and 50 degrees relative to the concrete surface,
- applying the tool to the concrete surface via the machine, wherein when the tool is rotated in a first direction such that the front edge is a leading edge, the tool removes material from the concrete surface, and wherein when the tool is rotated in a second direction opposite the first direction such that the rear edge is a leading edge, the tool polishes the concrete surface.
