Commercial floor coating is a competitive business, and the quotes you get will range wildly for what looks like the same job. The reason is that “epoxy floor” describes everything from a thin rolled-on coat to an engineered system, and the gap only shows up after the crew leaves. If you’re a facility manager, shop owner, or contractor buying a commercial floor, here’s the checklist of what to demand before you sign, so you’re comparing floors that will actually last, not just prices.
1. Demand a real prep spec
Ask exactly how they’ll prepare the concrete. The answer you want is mechanical profiling by diamond grinding, plus moisture testing. If the plan is to acid-etch or just clean and coat, walk away. Prep is the number-one predictor of whether a commercial floor survives its first year of traffic, and it’s the first corner cut on a lowball bid.
2. Demand the full system, in writing
Get the build spelled out: base coat, broadcast (flake or quartz if used), and topcoat, with the topcoat chemistry named. A polyaspartic topcoat matters for UV stability, chemical resistance, and fast return to service. A quote that just says “epoxy coating” with no layers or mil thickness is hiding something.
3. Demand a safety and traction plan
For a commercial space, slip resistance is a liability issue, not a preference. Ask what anti-slip solution they’ll include and where, especially for wet or oily zones, entries, and ramps. A serious contractor will have a clear answer, as we cover in our piece on non-slip coatings.
4. Demand a realistic downtime plan
Downtime is money. Ask how long the space is out of service and how they’ll phase the work to keep you running. Fast-curing polyaspartic systems shine here. Be wary of anyone who either promises the impossible or can’t give you a straight schedule.
5. Demand a warranty and references
Ask what the warranty covers, for how long, and what voids it. Then ask for local commercial references and recent work you can actually look at. An established installer will have both. Longevity in the trade is itself a signal: our crews are factory-trained, work only for us with no subcontractors, and we’ve coated well over a million square feet around Boston since 1974.
6. Demand to know who does the work
Find out whether the company’s own trained crews do the install or whether it’s handed to subcontractors. Consistent crews produce consistent floors; rotating subs are where quality slips. This one question tells you a lot about how the job will actually go.
The bottom line
The cheapest commercial quote is almost always the one skipping prep, thinning the system, or leaving out the topcoat and the safety plan. Demand the specifics above and the real cost of each option becomes clear, which is exactly the logic behind paint versus a coating system and why epoxy holds up when it’s specified and installed right.
Frequently asked questions
What should I look for in a commercial epoxy flooring contractor?
A written prep spec (diamond grinding plus moisture testing), the full system with the topcoat named, an anti-slip/safety plan, a realistic downtime schedule, a clear warranty, local references, and confirmation that trained in-house crews do the work rather than subcontractors.
Why do commercial epoxy quotes vary so much?
Because “epoxy floor” ranges from a thin rolled-on coat to an engineered multi-layer system. Cheaper quotes usually skip prep, use thinner product, or omit the topcoat and safety measures, which only becomes visible after the floor starts failing.
How important is the topcoat on a commercial floor?
Very. The topcoat carries the abrasion, chemical, and UV load. A polyaspartic topcoat adds durability and fast return to service, so it should be named and specified, not left vague.
How do I minimize downtime on a commercial floor install?
Choose a fast-curing system such as polyaspartic and ask the contractor to phase the work. A capable installer will give you a clear, realistic schedule for getting the space back in service.
