What we do

Three ways to finish a floor for good.

Concrete

Polishing

Multi-step mechanical grinding brings the aggregate to the surface and builds a glass-like sheen with no coatings to wear off.

Concrete

Staining

Acid and water-based stains react with the slab itself, giving showrooms and retail floors depth and color that won't chip.

Concrete

Sealing

Penetrating densifiers and topical sealers lock out dust, oil, and moisture — built for forklift traffic, not foot traffic.

How it's done

Six passes from bare slab to mirror finish.

01

Assess & prep the slab

We inspect the concrete for cracks, spalling, and old coatings, then patch and strip anything that would keep abrasives from biting evenly.

02

Coarse grind

Metal-bond diamond tooling opens the surface and levels it flat, cutting down until the aggregate we want exposed starts to show.

16–30 grit metal bond
03

Densify

A chemical hardener is spread across the ground surface and left to penetrate, reacting with the concrete to close its pores from the inside.

Lithium densifier · 30–60 min cure
04

Fine grind

We step up through progressively finer resin-bond diamonds, removing scratch patterns left by the previous grit each time.

50 → 100 → 200 grit resin bond
05

Polish

Final passes with 400–3000 grit pads burnish the slab up to the sheen level you've specified — satin, semi-gloss, or high-gloss.

Burnished, no topical wax
06

Seal & protect

A guard or stain-resistant sealer goes down last, then the floor gets a final buff so it's ready for foot and forklift traffic the same day.

Why Choose

Concrete Polishing

Upkeep

Low Maintenance

A damp mop handles daily upkeep. No waxing, no reapplying coatings, no scheduled downtime for refinishing.

Budget

Cost-Effective

Polishing the slab you already have costs less than replacing it, and the low upkeep pays off for years after install.

Materials

Eco-Friendly

No new flooring material to manufacture or landfill. The reflective surface also cuts down on artificial lighting needs.

Authorized Applicator

Customization options

Every slab reads a little differently once it's ground. Here's what you're actually choosing when you spec a polished floor.

Coloring

Stains and dyes can shift a floor's tone across a wide range without hiding the concrete underneath.

Aggregate Exposure

Grinding depth controls how much stone and gravel shows through — from a fine cream finish to full aggregate.

Gloss Level

Finishes range from a low matte sheen to a high-gloss polish, depending on traffic and light in the space.

Patterns & Designs

Saw-cut scoring, stencils, and engraving can lay borders, logos, or bands directly into the floor.

Common Questions

Answers before you call.

How much does polished concrete cost per square foot?+
Most warehouse and commercial polishing runs a modest per-square-foot rate depending on slab condition, aggregate exposure, and gloss level. Existing slabs with cracks or old coatings cost more to prep than a clean new pour. We give an exact number after walking the site.
Can you polish an existing floor, or only new concrete?+
Both. Most of our work is on existing slabs — grinding away old coatings, stains, and wear layers before moving through the polishing steps. New pours just need a shorter cure time before we start.
How long does the polishing process take?+
A typical warehouse bay is ready in a few days from prep through final seal, depending on square footage and how much crack or joint repair the slab needs. Retail and office spaces with tighter footprints often finish faster.
Is polished concrete slippery when wet?+
A properly polished and sealed floor is no more slippery than any other hard flooring, and we can adjust gloss level and add a slip-resistant additive to the sealer for areas that see spills or wash-down.
How do I maintain a polished concrete floor?+
Routine dust mopping and an occasional damp mop with a neutral cleaner is it — no waxing, stripping, or recoating. High-traffic industrial floors benefit from a re-burnish every couple of years to keep the sheen up.
