Stained concrete uses acid or water stain to build deep, variegated color into the concrete itself rather than coating over it. Detroit Concrete applies commercial concrete stains to new slabs or existing floors for showrooms, restaurants, office lobbies, and feature areas where rich color and a unique surface character beat any solid coating. Every project starts with a free written estimate.
A coating sits on top of concrete; a stain reacts into it. Acid stains chemically react with the slab's minerals to form permanent color compounds; water-based stains penetrate the slab to depth without forming a film on top. Either way, the result is color that is part of the slab, not paint on top of it, and the variegated character that comes from natural concrete variability becomes a feature instead of a flaw.
Stained concrete works best in spaces where rich color and a unique surface character matter: showrooms, restaurant dining rooms, hotel lobbies, office reception areas, and other public-visible interior surfaces. It pairs with polished concrete finishing, the polish brings out the stain's depth and protects the surface long-term.
We test the chosen stain on a small section of the actual slab first because each slab reacts differently. The test confirms color depth, reaction quality, and any prep needed before we commit to the full floor.
Prep slab for stain reaction
The slab is diamond-ground or chemically cleaned to remove surface contaminants and open the pores so the stain can react or penetrate properly. Existing coatings and sealers all have to come off first.
Apply stain in stages
Acid stain is applied in measured stages, allowed to react, then neutralized with a baking soda solution to stop the acid; water-based stain is sprayed or rolled in coats to build depth. Both produce variegated character.
Polish and seal
The stained surface is polished to bring out the depth and protected with a sealer rated for the use. Maintenance schedule (sealer refresh every several years) is documented at handoff.
Why stain is permanent
Stain Is in the Slab, Not on It
Concrete stain forms permanent color compounds inside the slab through chemical reaction (acid) or deep penetration (water-based). It cannot peel like a coating because there is no coating to peel; it cannot flake because the color is the slab. Wear takes decades and shows as patina rather than failure.
Coordinate with adjacent polished concrete for the polish-and-seal layer, and with the broader commercial decorative work where stained zones tie into stamped or coated zones in a coordinated design.
Acid vs water stain, slab prep, color predictability and pairing with polish.
Acid stain produces deep variegated color through chemical reaction; results are unique to each slab and less predictable. Water-based stain gives more predictable color and a wider palette. We recommend based on the look you want and how much variability you embrace.
Mostly. The stain test on your actual slab gives a strong read of how the color will land at full scale. Some natural variability is part of the appeal; if you want exact-uniform color, a coating is the better tool.
Both, with the right prep. Existing slabs need diamond grind or chemical cleaning to remove old sealers and contaminants so the stain reaches the concrete. Old slabs with extensive damage may not stain evenly; we test first.
Yes, for protection and to bring out the color depth. Sealer reapplication every several years in commercial settings keeps the floor looking sharp and the color saturated.
Typically several days from prep through stain, neutralize, polish and seal. Larger floors stretch to weeks. The schedule is in the quote so you can plan around the work.

What Detroit Operations Say About Their Stained Floors
Acid-stained showroom floor with depth and color that no coating could produce. Vehicles look incredible on it. Three years in, holding perfectly with one resealing cycle.
