Concrete Floor Coatings — SE Twin Cities Metro Area

  • Preparation is the product. Every floor is diamond-ground to a measured profile, cracks and spalls are repaired, and the slab is moisture-tested before a drop of product goes down. Coatings fail at the bond line; we refuse to let ours start there.
  • One-day garage installs. Fast-cure polyaspartic systems let us grind, repair, prime, flake, and topcoat most 2–3 car garages in a single working day — walk on it the next morning, park on it in 24–48 hours.
  • Year-round installation. Coating work happens indoors, so January is as good as June. Polyaspartic chemistry tolerates cold-slab installation that would stall an epoxy-only system.
  • Systems, not paint. Primer matched to the slab, broadcast matched to the use, topcoat matched to the traffic. A garage, a brewery, and a basement gym get three different builds — not one product in three colors.

Why choose LU Concrete

Mechanical diamond grinding on every job — never acid etching

Moisture testing before quoting, with mitigation primers where readings demand them

Commercial-grade polyaspartic, epoxy, and urethane systems in flake, quartz, and solid color

Concrete repair, resurfacing, and full replacement in-house when the slab needs more than a coating

Written scope and product data for every system we install

Signs it's time for replacement

  1. Dusting and pitting. Concrete that sheds fine dust or shows small pits is wearing at the surface — a ground-and-coated floor stops the erosion and seals the slab.
  2. Salt rings and winter staining. White chloride staining means de-icer is working into the pores. Each freeze drives it deeper; a coating or penetrating sealer shuts the door.
  3. Oil and tire marks that will not wash out. Bare concrete absorbs what lands on it. Coated concrete holds stains on the surface where a mop can reach them.
  4. A failed DIY or painted floor. Peeling gray paint or a flaking kit floor grinds off completely during our prep — the failed layer leaves with the laitance, and the new system bonds to bare concrete.

Our process

  1. Slab evaluation & moisture testWe inspect cracks, spalls, previous coatings, and drainage, and test moisture vapor before recommending a system.
  2. Diamond grindingPlanetary grinders with dust extraction open the surface to a specified concrete surface profile and remove old coatings and contamination.
  3. RepairCracks are chased and filled, spalls patched with polymer repair mortar, and joints treated per the system spec.
  4. Prime, broadcast, topcoatThe primer that fits your slab, the flake or quartz broadcast you chose, and a wear topcoat with the texture your use calls for.
  5. Cure & handoffYou get written walk-on and drive-on times, care guidance, and the product data for what is on your floor.

Frequently asked questions

What does a garage floor coating cost?

It depends on square footage, the repair the slab needs, and the system installed — a moisture-mitigation primer or heavy repair changes the number. Every quote is a written, itemized estimate after we see and test the floor, and the estimate is free.

Polyaspartic or epoxy?

Both, where each belongs: epoxy and moisture-tolerant primers at the slab, polyaspartic at the surface for UV stability, hot-tire resistance, and fast cure. Polyaspartics are themselves a fast-curing type of aliphatic polyurea — so when a company advertises a "polyurea floor," it is the same chemistry family we install as a topcoat. Single-product floors are a marketing simplification; layered systems last.

Can you coat old, damaged concrete?

Usually — grinding and repair handle most wear, and resurfacing overlays can rebuild a badly scaled surface before coating. When a slab is structurally failed, we say so and quote the replacement instead; we do that work too.

How soon can it be walked and parked on?

Typical polyaspartic systems take foot traffic the next morning and vehicles in 24–48 hours; commercial urethanes vary by build. Exact times come in writing with the installation.

Do coatings make the floor slippery?

Texture is a choice, not an accident. Flake and quartz broadcasts add grip, and topcoats take anti-slip additives — we match the texture to how the space is used, from smooth showroom to wash-down kitchen.
