What Polished Concrete Actually Is
Not a coating, not a sealer — a mechanical transformation of the slab itself into a dense, light-reflective, permanently finished floor.
Grinding, Honing, Polishing — Like Gemstone Work, at Floor Scale
Polished concrete is exactly what it sounds like: we take the slab you already own and polish it the way a lapidary polishes stone — with diamonds, in stages, until it shines. There's no film on top to scratch, yellow, or peel. The finish is the concrete, which is why polished floors in warehouses and big-box stores survive decades of forklifts and foot traffic without a recoat.
The process runs through two families of diamond tooling. Metal-bond diamonds — coarse, aggressive segments in roughly 30 to 120 grit — do the heavy cutting: flattening the slab, removing old coatings and laitance, and exposing the amount of aggregate you want to see. Then resin-bond diamonds take over, stepping through 100, 200, 400, 800, 1,500, and up to 3,000 grit, each pass refining the scratch pattern of the one before it until the surface reads as sheen instead of scratches.
In between, we flood the floor with a lithium silicate densifier — a penetrating liquid that reacts with the free lime in concrete to grow additional hard mineral (calcium silicate hydrate, the same stuff that makes concrete strong) right inside the surface. Densifying is what turns a soft, dusty slab into a floor hard enough to take a true polish and hold it under traffic.
The final step is a penetrating stain guard, burnished into the surface at high speed. It doesn't change the look — it just buys you time when coffee, oil, or wine hits the floor.
