Concrete cutting, polishing, and coloring treatment solutions and methods
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.
1. A method for finishing or refinishing concrete, the method comprising the steps of:
saturating a surface of the concrete with water;
wetting the surface of the concrete with a cutting compound, the cutting compound comprising particles that penetrate pores in the surface of the concrete;
applying at least one tool having a predetermined cutting edge to the surface of the concrete while the surface of the concrete is wet; and
after the surface of the concrete dries, applying at least one dry tool to polish the surface of the concrete.
2. The method of claim 1 , further comprising removing a sealant or coating from the concrete prior to saturating the surface of the concrete with water.
3. The method of claim 1 , further comprising adding a coloring agent and a densifier after the step of applying at least one tool to the surface of the concrete.
4. The method of claim 1 , wherein the cutting compound comprises a colloidal silica.
5. The method of claim 4 , wherein the particles of the colloidal silica have a size of about 7 nm.
6. The method of claim 4 , wherein the particles of the colloidal silica have a size ranging from 9 nm to 1000 nm.
7. The method of claim 1 , wherein the predetermined cutting edge is applied to the surface at an angle between 30 degrees and 90 degrees relative to the surface.
8. The method of claim 1 , wherein the predetermined cutting edge is at least one of a sharp edge, a chamfered edge, and a radiused edge.
9. The method of claim 1 , wherein the at least one tool comprises a tool body that includes abrasives.
10. The method of claim 1 , wherein the at least one tool comprises a tool body that omits abrasives.
11. The method of claim 1 , wherein the step of applying at least one tool includes a series of tools comprising a 6-grit tool with a trapezoidal shaped 90-degree edge; a 100-grit, 10 segment tool with a radiused edge; and a 400-grit semi-metal tool;
and the dry tool comprises an 800-grit dry polish.
12. The method of claim 1 , wherein the at least one tool comprises at least one of a trapezoidal, rectangular, and triangular shape.
13. The method of claim 1 , wherein the at least one tool is applied by a machine, the at least one tool being attached to a drive mechanism propelled by a motor on the machine.
