Abstract
Systems and methods for treating concrete, which includes the steps of wetting a surface of concrete with a colloidal silica; cutting the softened surface to provide a cut surface; and polishing the cut surface.
Claims20
A method for finishing concrete, comprising:
- wetting a surface of concrete with a densifier comprising at least 5% colloidal silica, by weight, and a stabilizer to impart the concrete with a softened surface;
- cutting, honing or planing the softened surface wetted with the densifier to provide a generally flat, planar surface;
- and
- polishing the generally flat, planar surface.
