Six passes. Each one finer than the last. The result is permanent — there's nothing to strip, recoat, or replace.

We walk every square foot before we grind a single pass. We're looking for soft spots, previous sealers or coatings that need stripping, structural cracks, and anything that would telegraph through to the finished surface. Cracks get filled with semi-rigid epoxy filler and left to cure flush before grinding starts. Polish the prep wrong, and the imperfections become permanent.
The first pass uses coarse metal-bond diamond segments (16–30 grit) to do the heavy work: cut through any old sealer, remove the weak surface layer of the slab, level any high spots, and open the concrete's pores so the densifier can penetrate later. Industrial HEPA vacuums run continuously — we don't leave dust in your building.
The 80–100 grit pass refines the scratch pattern and further opens the pores. We then apply a lithium silicate densifier across the wet surface. It reacts with free lime in the concrete to form calcium silicate hydrate — chemically filling the pores and hardening the surface from the inside. This is what makes polished concrete durable for decades.
We switch from metal-bond to resin-bond diamonds. The 200 and 400 grit resin pads refine the scratch from the metal-bond passes and start developing the first visible sheen. Matte-finish floors stop around here — the 400 grit delivers a clean, flat look with just enough reflectivity to brighten a space without drawing attention to itself.
Each successive grit removes the scratches from the previous one. The 800 grit delivers a satin finish. The 1500 grit is where most commercial floors land — a clean semi-gloss that reflects light without being a mirror. The 3000 grit is the full showroom treatment. We run as many passes as your chosen finish level requires, no fewer.
A penetrating stain guard goes on last. It doesn't change the look or sheen level — it closes off any residual surface porosity so oil, water, and most chemicals bead up and wipe off rather than soaking in. Applied by mop, burnished in. The floor is ready for foot traffic the same day.
