Commercial polyurea floor coating in western Wisconsin runs $6 to $10 per square foot depending on prep. A 1,500 sqft auto shop typically lands between $9,000 and $15,000. A clean 3,000 sqft warehouse can come in closer to $6 per foot. A grease-soaked mechanic's bay can run $10 or more.
Commercial jobs live or die on prep. If your slab is clean and open, commercial is actually cheaper per foot than residential. If it's beat up, oily, and full of equipment we have to work around, the number goes the other way.
Why is commercial sometimes cheaper than residential?
People assume commercial costs more because the number is bigger. On a per-square-foot basis, it's often the opposite. Here's why:
- Commercial jobs have fewer cut-in edges relative to total square footage (big open floor vs. a bunch of small residential garage walls)
- Crews can run bigger equipment - ride-on grinders instead of walk-behinds
- Material bulk pricing: we're buying polyurea by the 5-gallon pail, not the kit
- One mobilization, one setup, one cleanup on a large open slab
On a bare 3,000 sqft open warehouse floor, I can sometimes come in at $6.00 to $6.50 per sqft. That's cheaper per foot than any residential garage.
When does commercial get expensive?
When the slab fights us back. The things that push commercial jobs toward $10 per foot or beyond:
- Oil and grease saturation: old mechanic's bays where years of drips have soaked into the concrete. We have to degrease, sometimes shot-blast or do a deeper grind, and occasionally use an oil-tolerant primer
- Equipment work-arounds: lifts bolted to the floor, hydraulic presses, heavy shelving that can't be moved. We tape off, cut in, and coat in sections
- Off-hours work: if you need us nights or weekends so you don't lose production, that carries a premium
- Trip hazards and ADA transitions: if the coating changes the floor elevation at doorways
- Moisture vapor from below-grade slabs: sometimes we need to test and spec a vapor-mitigating primer
What does a typical auto shop quote look like?
A 2-bay auto shop in Hudson, maybe 1,200 sqft of floor space, 10 years of use:
Prep (shot blast or aggressive grind on oil-stained areas): $1,800. Materials (Valence polyurea + flake + polyaspartic): $2,400. Labor (2 days, 2-man crew): $3,200. Overhead, mobilization, warranty reserve: $900. Total: $8,300, or about $6.90 per sqft.
Same shop with cleaner floors and no oil staining? Probably $7,400. Same shop with heavy contamination and tight work-arounds? Probably $10,500.
What commercial spaces are we good for?
We do a lot of:
- Auto repair shops and quick-lube bays
- Small warehouses and distribution centers
- Mechanical rooms and utility spaces (see utility room coatings)
- Veterinary clinics and kennels (urine resistance matters)
- Breweries, food prep spaces (check with me on FDA-compliance requirements)
- Showrooms and small retail
- Fitness and gym spaces

Why polyurea for commercial?
Commercial floors see more abuse than residential. Forklifts, dropped tools, dragged pallets, hot tires, harsh chemicals. Polyurea gives you 4x the abrasion resistance of epoxy, 311% elongation, and a 674 PSI bond to properly prepped concrete. That's the difference between coating a floor once and coating it every five years.
Epoxy commercial floors are still sold, and they are cheaper up front - $3 to $5 per sqft on a basic install. But every commercial epoxy floor I've walked into after year 4 looks beat up. Chipped at traffic lanes, delaminating at cracks, fading where the sun hits. I wrote more about that in polyurea vs epoxy.
How we quote commercial work
Commercial quotes require a walk-through. I come to the site, look at the slab condition, measure real square footage (not just wall-to-wall), check for moisture issues on below-grade slabs, and ask you how the space gets used. Then I write a quote that accounts for the actual prep needed, not a generic per-foot number.
For anything over 2,000 sqft or anything with an oil-staining history, I always do the walk-through in person. That's the only way to give you a number you can actually plan around.
Questions I'll ask on the first call
- How many square feet of floor?
- What's the current floor condition - bare, sealed, painted, old epoxy, oil-stained?
- Is there equipment bolted down or can we move everything out?
- How many hours of downtime can you give us?
- Is this new construction or an existing slab?
With those answers I can usually give you a ballpark on the phone, and a firm quote after the site visit.
