The slab you already own, ground and densified into a finish floor. Typical installed cost, durability, where it works and how to care for it.
Polished concrete converts an existing structural slab into the finished surface by grinding it with progressively finer diamond abrasives and applying a chemical densifier that reacts with free lime to harden the surface. There is no coating to peel, no seams, and nothing to replace. Appearance depends on how deep the grind goes: a cream finish exposes almost no aggregate, a salt-and-pepper finish exposes fine sand, and a full aggregate exposure reveals the stone. It is cold, hard, loud, and unforgiving of dropped glassware — and nearly indestructible.
Lithium, sodium or potassium silicate penetrates the slab and reacts with calcium hydroxide to form additional binder, hardening the surface and reducing dusting.
Measured 1–4 (or by grit sequence). Level 1 is a flat matte ground finish; Level 4 is a mirror polish requiring grits up to 3000. Higher gloss means more labor and higher cost.
Cream (no exposure), salt-and-pepper (fine), and full aggregate. Deeper exposure means removing more material — more passes, higher cost, and it reveals whatever the pour actually contains.
Old adhesive, patches, saw cuts, spalling and prior coatings all show. Grinding reveals history, it does not erase it. Always test-grind a small area first.
Acid stains react chemically for variegated, mottled color. Water-based dyes give consistent, vivid color but less UV stability. Both are applied mid-process.
Control joints are filled with semi-rigid polyurea to support edges under traffic — skipping this causes joint spalling under forklift and cart wheels.
| Gloss levels | 1 (matte) – 4 (mirror) |
|---|---|
| Exposure | Cream, salt-and-pepper, full |
| Coating | None — mechanical polish |
| Renewable | Yes, indefinitely |
The lowest-cost floor in a new build is often the slab you were already paying for. But the polish quality is capped by the quality of the pour — coordinate with the concrete contractor before the slab goes down.
Each feature paired with the benefit it delivers. A spec on its own tells you nothing about whether it is worth paying for.
In new build the structural slab becomes the finished floor. The lowest-cost floor in the building is often the one you were already paying for.
Silicate reacts with free lime to harden the surface from within, reducing dusting and raising abrasion resistance without adding a coating.
Nothing to peel, blister or delaminate, because the finish is mechanical. Forklift traffic does not lift it.
Burnishing restores gloss and a full regrind resets the floor entirely, indefinitely.
Cream, salt-and-pepper or full stone exposure from the same slab, so the look is set by how deep you grind rather than what you buy.
Drawn from the same ratings used everywhere else on this site, so this cannot flatter the product beyond what the comparison table says.
The specifications below decide how this floor performs. Ask for them in writing — a sample board and a price per square foot do not tell you any of it.
Polished Concrete runs $4.00–$12.00 per square foot installed in 2026 — $0.00 to $2.00 for material and $4.00 to $10.00 for professional labor. Spread across an expected 50 to 100 year service life that works out near $0.11 per square foot per year. Regional variation of 20 to 40% is normal, and demolition, subfloor prep and trim are extra.
50 to 100 years, assuming it went into an appropriate room over a properly prepared substrate and gets the maintenance it needs. The lowest-cost floor in a new build is often the slab you were already paying for. But the polish quality is capped by the quality of the pour — coordinate with the concrete contractor before the slab goes down.
Basement (below grade), Home Gym, Garage / Workshop. Warehouses, retail, breweries, showrooms. Modern residential and loft conversions.
Bedroom. Slabs with extensive cracking or prior adhesive contamination. Spaces where comfort and warmth matter.
It tolerates water well but has a vulnerability, usually at the seams or the backing. Fine for splashes, not for standing water without care.
Dust-mop daily to remove abrasive grit. Auto-scrub or damp-mop with a pH-neutral cleaner. Critically: never use acidic cleaners — they attack the cement matrix.
Same family first, then products with a similar look from other families.
Poured aggregate composite — the 75-year institutional floor.
Seamless chemical- and impact-resistant coating systems.
Stone-composite core: 100% waterproof and dimensionally rock-steady.
Densest, hardest, most water-resistant mainstream floor — and the best wood-look plank made.
