Polished Concrete Specialist
Polished Concrete Floors
Vancouver, WA & Portland, OR
True mechanical polishing using progressive diamond tooling to achieve a glass, satin, or matte finish. No coatings. No overlays. Just the concrete itself — refined to a surface that lasts the lifetime of the building.
What Is Polished Concrete?
Polished concrete is a multi-step mechanical process where the concrete slab is ground through progressively finer diamond tooling — from coarse grinding to ultra-fine polishing — until the surface reaches the desired level of sheen and aggregate exposure.
A chemical densifier is applied during the process to harden the concrete and increase its density. The result is a floor that is part of the concrete itself, not a coating applied on top. It won't peel, chip, or delaminate. It gets harder over time.
Available finishes range from matte (400 grit) to satin (800 grit) to glass (1500–3000 grit). Aggregate exposure is determined during the grinding phase and can range from a cream finish to full aggregate reveal.

THE PROCESS
How a Polished Concrete Floor Gets Built
Initial Assessment
On-site walkthrough to evaluate slab condition, aggregate, existing coatings, and any repair or correction work required before polishing begins.
Slab Preparation
Grinding to remove existing coatings, adhesives, or surface contamination. Crack repair and slab correction to bring the surface within tolerance.
Progressive Diamond Grinding
Sequential passes with progressively finer diamond tooling — from coarse grinding to medium refinement — to open the slab and expose aggregate at the desired level.
Densifier Application
Chemical densifier applied at the appropriate grit stage to penetrate and harden the concrete, increasing surface density and scratch resistance.
Polishing to Specified Finish
Final polishing passes to achieve the specified sheen level — matte (400 grit), satin (800 grit), or glass (1500–3000 grit).
Sealer and Guard Application
Penetrating sealer and stain guard applied to protect the surface and simplify maintenance. Final inspection and walkthrough with the client.
