Grinding a concrete slab to a hard, sealed finish transforms it into a surface that lasts decades with only damp-mopping. Detroit Concrete takes your existing slab, densifies it chemically, and polishes to your chosen gloss, satin for soft reflection or high-gloss for mirror clarity. No coating to peel. No recoating needed. Every project includes a free written estimate.
When you polish concrete, you're not applying a layer on top, you're transforming the slab itself. Diamond grinding removes surface imperfections and opens the pore structure. A chemical densifier hardens the concrete from the surface inward, locking it into a tight, low-dust matrix. Then polishing brings it to the gloss you want.
The result is a floor with no coating to fail, peel, or need reapplication. Satin finishes sit around 400 grit; full high-gloss can reach 3000 grit or beyond. The choice is yours, and the finish is permanent.
Maintenance is straightforward: damp-mop once a week. No stripping, no resealing cycles, no special products. Our approach to interior concrete floors stays consistent across stained and epoxy systems too, durability first, simplicity second.

The process
Polishing a Concrete Floor Step by Step
Assess slab readiness
We measure moisture levels, check for cracks or cold joints, and identify any old coatings that need removal. A slab in poor condition may need a micro-topping overlay before polishing can begin.
Grind and densify
Progressive grinding with diamond tooling removes surface wear and opens the concrete matrix. We then apply a chemical densifier that penetrates and hardens the slab, creating a tight, durable surface.
Polish to gloss level
Continued grinding through finer grits brings the slab to your chosen finish, soft satin for a subtle look or high-gloss for maximum reflection. Stain protection is applied as part of the system.
Cure and handoff
The densifier and sealer cure on schedule. A final buff brings out clarity and depth. You receive the floor with a simple damp-mop maintenance routine that keeps it looking new.
Choosing the right floor
Polished vs Epoxy, Stain, Overlay
Polished concrete and epoxy coatings are the two main interior options. Polished is the slab itself, permanent and coating-free. Epoxy is a seamless layer that offers more color and pattern variety but eventually needs recoating.
Stained concrete uses dye worked into the slab, often paired with a polished or sealed finish for protection. Micro-topping is a thin overlay that prepares an unsuitable slab for polishing. Self-leveling underlayment corrects flatness issues before any finish is applied.
Gloss levels, slab conditions, density and maintenance for polished floors in Detroit.
Most can, but the slab condition decides the finish. We test for moisture, cracks and old coatings first. Slabs with surface damage may need a micro-topping first to give the polish a clean canvas.
From a soft satin (around 400 grit) to a mirror-like high-gloss (3000 grit and beyond). The gloss level is your choice; we grind through the right number of passes to reach it.
Sealed properly with a stain-protector, polished concrete resists stains well. Spilled wine or oil should still be wiped up promptly, but the densified surface is far less porous than untreated concrete.
Concrete temperature follows the room, so it is no colder than tile or stone in the same conditions. Pair it with heated floor underlayment if you want warmth underfoot.
Decades, with basic damp-mop maintenance. There is no coating to fail and no surface to wear off; the polish is the slab itself, densified into a hard matrix that holds up to daily life.

What Detroit Homeowners Say About Their Polished Floors
Polished the whole main floor after the kitchen reno. The reflectivity makes the whole room look bigger and the maintenance is just a damp mop once a week.

Picked a satin gloss level instead of full high-gloss for the basement. Soft underfoot look, hard as can be, and the kids' toys roll cleanly across it.

They tested the slab first and recommended a micro-topping before polishing because of some surface cracks. Saved us from a polish-over-cracks disaster, exactly the right call.

Stain protector is doing its job. We have spilled coffee and red wine and both wiped up clean. Maintenance is way less than the hardwood we replaced.
