Methods for grinding and polishing dried concrete using amorphous colloidal silica solution

A method for grinding and polishing dried concrete, the method comprising:

• wetting a surface of dried concrete with a solution including amorphous colloidal silica, wherein the solution acts as an abrasive to facilitate removal of stock from the concrete surface;
• permitting the colloidal silica to penetrate the concrete surface for at least 30 minutes;
• cutting the surface of the concrete with a bladed tool, the bladed tool having the blade portion at an angle between 30 degrees and 90 degrees relative to the surface of the concrete;
• applying pressure to the bladed tool to facilitate penetration and cross-linking of the amorphous colloidal silica with shavings of the concrete surface to harden the dried concrete;
• permitting the concrete surface to dry;
• applying a coloring product to the concrete surface;
• applying a concrete hardener to the concrete surface, wherein the concrete hardener is permitted to penetrate the concrete surface for at least 30 minutes;
• dry polishing the concrete surface using a tool;
• spraying the concrete surface with a sealer;
• and
• polishing the concrete surface with a burnishing pad.
