How a polish is builtTen passes, coarse to mirror — see the grit sequence+

Polished concrete isn't a product you buy, it's a sequence of diamond grits. Skipping one shows up as scratches under the gloss six months later. We don't skip.

Assess

Moisture test, hardness check, and a look at what's on the slab now. This decides the tooling.

Grind

Metal-bond diamonds 30 to 120 remove coatings, glue and high spots and expose the aggregate you chose.

Densify

Lithium silicate hardens the surface so it takes a polish and resists dusting for good.

Hone

Resin-bond 50 to 200 closes the scratch pattern left by the metals.

Polish

400, 800, 1500 or 3000 grit, depending on the sheen you signed off on.

Guard

Stain guard burnished in. Walk on it the same day.

What it costs

Straight numbers,
before we visit.

Most contractors make you book a visit to hear a price. These are the ranges our Houston and Austin jobs actually land in. The written estimate is exact.

Polished concrete

$3 – $8/ sq ft

Grind, densify, polish and guard. Low end is a 400-grit matte on a clean slab; high end is 1500+ gloss with aggregate exposure or heavy glue removal.

Epoxy floor system

$4 – $9/ sq ft

Grind to CSP 3, primer, 100% solids epoxy body coat, urethane or polyaspartic topcoat. Flake and metallic finishes sit in the upper half.

Garage floor, 2-car

$2,500 – $4,500flat

Roughly 400–500 sq ft. Diamond grind, crack fill, full-broadcast flake, polyaspartic topcoat. One day on site, park on it in 24–48 hours.

Grinding & coating removal only

$1.50 – $4/ sq ft

Thinset, carpet glue, paint or failed epoxy removed and the slab left flat and profiled for someone else's floor.

Exterior & fence painting

quotedper job

Depends on surface, height and prep. Send photos and a rough linear footage for a same-day ballpark.

Ranges reflect typical 2026 jobs over 1,000 sq ft. Under 1,000 sq ft carries a minimum. Nights and weekends add 10–15%.

What moves the number

  1. What's on the slab nowCarpet glue, thinset or a failed coating adds grinding passes before we can start the real work.
  2. Square footageSetup and mobilisation are fixed. Bigger floors cost less per foot.
  3. Sheen and exposureEvery grit level above 400 is another full pass over the floor.
  4. MoistureA high-moisture slab needs a vapor barrier primer under any coating. We test first, so it never surprises you later.
  5. ScheduleWorking around an open business at night is doable; it's just more hours.

Questions we get on every call

Ask the crew,
not a call center.

The person who answers the phone is the person who will measure your floor.

How long does a polished floor take?

Plan on 1,000 to 1,500 sq ft per crew per day for a full grind-and-polish. A 5,000 sq ft retail floor is typically four to five working days, and you can walk on it the same day we finish.

Will there be dust everywhere?

No. Every grinder runs tethered to a HEPA dust extractor, and we wet-grind where the space calls for it. Adjacent rooms stay open during the work.

Epoxy or polyaspartic — which one do I want?

Epoxy is the thick, tough body coat. Polyaspartic is the fast-curing, UV-stable topcoat. Most garages get flake epoxy with a polyaspartic top. Sun-facing bays and outdoor patios get polyaspartic all the way through.

Do you test for moisture?

Every slab, before we quote a coating. Moisture is why coatings peel. If the slab reads high we price in a moisture-mitigation primer instead of finding out the hard way.

Can you work while my business stays open?

Yes. Restaurants and retail are usually done overnight or in zones. Tell us your hours and we build the schedule around them.

Is there a warranty?

Every coating system comes with a written warranty against peeling and delamination. Polished concrete doesn't peel, so it carries a workmanship guarantee instead.
