How Concrete Grinding
and Polishing Works
We produce beautiful polished concrete with a mechanically polished technique that does not require a topical coating that will wear away.
Mechanical polishing densifies and hardens the surface of the concrete up to 10x its normal strength to resist stains, cracks, and damage. Once concrete grinding and polishing is complete, the surface will feel as smooth as glass.
Our polished concrete contractors use a process similar to sanding wood: commercial-grade grinding machines use diamond-impregnated discs to gradually grind down the surface of the concrete with progressively finer grits. After a rough grind, we apply a densifier chemical to the surface that hardens and densifies the concrete surface and enables a fine polish. We continue polishing with finer products until we achieve the shine you want which may be honed or matte or very high-gloss.
The concrete grinding process doesn’t remove as much of the surface as you would think. In most cases, just 1.6mm of the floor’s surface will be removed without extending into the concrete aggregate. For a terrazzo look, up to 6mm of the surface may be removed.
