Why commercial floors fail here — and how a good spec prevents it
Commercial coatings rarely fail because the product was bad. They fail because the system did not match the slab or the use. Around New Orleans three conditions do most of the damage.
Vapor coming up through the slab
Moisture in a slab can make a floor coating fail after it goes down, which is why coating makers generally require a moisture test first. On a big floor that shows up as blistering in patches, often where the slab was poured on the wettest ground. Testing in several spots catches it.
Floors that sweat
South Louisiana has a hot, humid climate, and humidity can matter twice for a coating: moisture in the slab, and condensation on a cool slab during application. Warehouses with big doors and no climate control are the classic case. A floor that is wet on muggy mornings needs texture in the walk lanes and a schedule that keeps coating work away from those mornings.
Wheels, chemicals, and hot water
Forklift wheels grind, shop fluids soften cheap topcoats, and kitchen wash-down at high temperatures can crack a coating that was never meant for it. Each one points to a different system, which is why the use comes before the color.
Facility types and what changes for each
| Facility | What the floor faces | What usually goes down |
|---|---|---|
| Auto and service shops | Oil, brake fluid, dropped tools, hot tires | Thick epoxy body coat, chemical-resistant topcoat, grit in the walk lanes |
| Restaurant and commercial kitchens | Hot water wash-down, grease, constant wet floors | Urethane cement rather than epoxy, with an integral cove base at the walls |
| Warehouses and distribution | Forklift and pallet-jack wheels, long open bays | High-build epoxy, joint treatment, striped aisles and staging zones |
| Retail and showrooms | Foot traffic, appearance, short closing windows | Flake or metallic systems with a fast-cure topcoat |
| Clinics, gyms, and offices | Cleaning chemicals, rolling chairs, equipment | Solid-color or flake epoxy with a urethane or polyaspartic topcoat |
What a commercial installation includes
- Walk the space and test the slab. Square footage, drains, joints, existing coatings, and moisture readings in more than one spot — a large slab rarely reads the same everywhere.
- Mechanical prep. Diamond grinding for most rooms, shot blasting for big open floors. Either way, the surface is opened up, not washed with acid.
- Repair joints, cracks, and drains. Moving joints get a flexible filler; dead cracks get a rigid one. Slope to drains is checked before anything is built on top.
- Prime and control vapor. A moisture-mitigating primer where readings call for it. This is the single most important line on a commercial bid around here.
- Build coats and finish. Body coats to the thickness the traffic needs, broadcast aggregate where people walk on wet floors, then the topcoat.
- Lines, cove, and handover. Safety striping, cove base where the code or the cleaning crew needs it, and cure times written down before the doors reopen.
What commercial epoxy flooring costs
$4–$12 per square foot, scaled by square footage and downtime needs.
| Project | Typical range |
|---|---|
| Small commercial bay or shop (under 1,000 sq ft) | $6–$12 / sq ft |
| Mid-size space (1,000–5,000 sq ft) | $5–$9 / sq ft |
| Large warehouse or open floor (5,000+ sq ft) | $4–$7 / sq ft |
| Add-on: integral cove base | priced per linear foot |
Per-foot price falls as the floor grows, because setup spreads over more area. Night or phased work to keep a business open is the usual adder.
Typical installed ranges for the Gulf South metro — planning numbers, not quotes and not our prices. NOLA Concrete Coatings does not price or perform work; the real number comes from the installer after a look at the slab.
What to have ready before the site visit
- Rough square footage of each area, and which ones can close at the same time.
- What actually spills or rolls on the floor — the chemicals by name if you have them.
- Your hours, including whether nights or weekends are possible.
- Any inspector, landlord, or insurer requirement you already know about.
- The age and history of any coating that is already down.
A written quote worth comparing lists four things as separate lines: prep, repair, the coating system, and the finish. On a commercial bid, look hardest at the prep and primer lines; those are where low bids save money.
- 1PrepThe method (diamond grinding or shot blasting), the moisture test, and any moisture-tolerant primer that test calls for.
- 2RepairCrack and spall repair, removal of an old coating or sealer, and whether that number is fixed or an allowance the crew settles once the floor is opened up.
- 3Coating systemThe chemistry, the number of coats, and the total mil thickness, not just a product name.
- 4FinishSolid color, flake, or metallic; the topcoat; and the return-to-service windows for foot traffic and for vehicles.
Commercial flooring questions
How much does commercial epoxy flooring cost in New Orleans?
Most commercial floors run $4 to $12 per square foot. Small bays under 1,000 sq ft land around $6 to $12; large open floors over 5,000 sq ft around $4 to $7. Night or phased work is the usual adder.
Can the floor be done without closing the business?
Often, yes, by doing it in sections or overnight. Fast-cure polyaspartic or methyl methacrylate systems can put an area back in service the same day, at a higher material price.
Is epoxy right for a restaurant kitchen?
Usually not on the hot line. Boiling water and steam cleaning can shock an epoxy floor loose; urethane cement is the common choice there, with a cove base so the floor-to-wall joint can be cleaned.
How long does a commercial coating last?
It depends on traffic and the build. A thin coat in a forklift aisle can wear through in a few years; a full-thickness system with a renewed topcoat can last many more. Ask what topcoat maintenance the installer recommends and how often.
