What Is Polished Concrete?

A Permanent Floor — Not a Coating

Polished concrete is not a coating applied on top of your slab — it is the slab. We use progressively finer diamond tooling to mechanically grind and refine the concrete surface, then apply a lithium silicate densifier that chemically hardens the concrete from within.

The result is a floor that cannot peel, chip, or delaminate. In Arizona's extreme heat, polished concrete outperforms epoxy coatings that can bubble, yellow, or lift under UV exposure and thermal cycling.

A penetrating guard sealer is applied as the final step, protecting against oil, water, and chemical spills while maintaining the natural look of the concrete.

Why Polished Concrete

Built to Last in Arizona's Climate

Dust-Free Diamond Grinding

We use industrial diamond grinders with HEPA-filtered vacuums — no concrete dust left behind on your property.

Multiple Sheen Levels

From a matte industrial finish to a high-gloss mirror shine. We match the sheen to your space and use case.

Densifier & Hardener Application

Lithium silicate densifier penetrates the slab, chemically hardens the surface, and dramatically reduces porosity.

Stain & Guard Sealer

A penetrating guard sealer protects against oil, water, and chemical spills — ideal for garages, warehouses, and retail floors.

No Coatings to Peel or Chip

Polished concrete is the slab itself — there is no topcoat to delaminate, peel, or chip under heavy traffic or UV exposure.

ADA-Compliant Slip Resistance

Properly polished concrete meets OSHA and ADA slip-resistance standards when finished with the correct grit and guard sealer.

The Process

How We Polish Concrete

01

Slab Assessment

We inspect the existing concrete for cracks, spalling, contamination, and hardness. Any repairs are completed before grinding begins.

02

Coarse Diamond Grinding

Metal-bond diamond tooling removes surface laitance, old coatings, and high spots. Grit progresses from coarse to fine.

03

Densifier Application

Lithium silicate densifier is applied between grinding passes. It reacts with the concrete to fill pores and harden the surface.

04

Fine Polish & Guard Sealer

Resin-bond diamond tooling refines the surface to the desired sheen. A penetrating guard sealer is applied as the final step.
