Commercial epoxy systems we put down
Solid epoxy with a topcoat
A full-thickness epoxy base sealed with a tougher topcoat. It's the standard build for warehouses, shops and showrooms that see steady foot, cart and forklift traffic.
Flexible and hybrid builds
For floors that take hot washdowns, sit next to cold rooms or rest on a slab that moves, a flexible urethane or hybrid system usually holds up better than rigid epoxy.
What goes into a commercial epoxy floor in Martinez?
A commercial or industrial epoxy floor coating is a resin system bonded to your concrete that holds up to forklifts, foot traffic and chemical spills. In Martinez we fit each one to what your building does and how long you can close.
Most calls start with a shop or warehouse floor that's peeling, stained or worn through where the forklifts turn. The price moves with the size of the floor, how much concrete grinding and surface prep and crack repair the slab needs, whether moisture calls for a special primer, and how thick a system and which topcoat your traffic needs. The schedule turns mostly on how long the topcoat takes to cure and when you can close, and I'll put your price in a written estimate after I see the slab.
From slab prep to topcoat on commercial epoxy
I start with what your floor faces, like chemicals, forklifts, washdowns and downtime. Then I pick a system for your building, not the one we use for garage floor coatings at a house.
Test and inspect the slab
We check moisture, cracks and old coatings first, because most commercial floors that peel started with a slab nobody tested.
Grind and repair
Our crew grinds the concrete to open it up, fills cracks and patches chipped spots so the coating has something sound to grip.
Prime and build the base
We put down the primer the moisture reading calls for, then the epoxy base at the thickness your traffic needs.
Topcoat for your shutdown
The topcoat sets how soon equipment can roll back on, so we choose between urethane and polyaspartic floor coatings to fit your downtime.
Why Martinez shops call Stonefield
I taught myself floor coatings and learned the rest beside experienced crews, so I've seen how floors fail and why. We're known for concrete floors that stay bonded, and you'll know what we'll do and why before you sign anything. Call (925) 231-8429 to get started.
I look at your floor myself
The person who walks your floor and writes the estimate is the same one on site with our crew during prep and install, so nothing gets lost between the bid and the work.
Prep first since 2017
We've been in business since 2017 and put our time into testing and grinding before any color goes down, because a floor that peels usually started with a slab nobody prepped right.
Licensed and fully insured
We're licensed and fully insured for the work we do. The state contractor board counts preparing the surface as part of flooring work, and that's how we treat it on your floor.
What happens after you call about a commercial floor?
We plan the job around how your business runs, so the prep, the system and the downtime are settled before the crew shows up and you can schedule staff and deliveries around it.

Commercial epoxy floor questions
How much does commercial epoxy flooring cost in Martinez, CA?
Epoxy floor coating in the San Francisco area usually costs about $4 to $15 per square foot of floor coated, and that's the going rate around here, not our quote. Where your floor lands depends on how much grinding and repair the slab needs, whether it needs a moisture barrier primer, how thick the system is and which topcoat you pick. I'll give you your own number in a written estimate after I see the slab.
How long does a commercial epoxy floor take before forklifts can drive on it?
It comes down mostly to the topcoat. One cost guide says polyaspartic topcoats let forklifts back on in 24 to 48 hours, while standard urethane topcoats need 3 to 5 days before heavy loads. We match the topcoat to how long you can stay shut down and tell you the downtime before we start.
How long does a commercial epoxy floor coating last?
One cost guide expects a standard 100% solids epoxy with a topcoat to last 7 to 12 years in commercial traffic, while a thin rolled-on coat lasts about 2 to 4 years. That's why a cheap thin coat usually costs more over time, since you'll be recoating far sooner. Ask every bidder how thick their system is.
Why does the slab need a moisture test before an epoxy floor?
Because moisture coming up through the concrete is what pushes coatings off. One cost guide says a slab reading over 75% to 80% relative humidity calls for a moisture vapor barrier primer, and that skipping it is the biggest cause of commercial floor failure. We test before we price the primer, and you should ask any bidder for their result and whether the primer is included.
How do I choose the right epoxy system for a warehouse or plant?
Match the system to what the floor faces, like chemicals, temperature swings, traffic and impact, sanitation and your shutdown window. One maker notes that urethane takes sudden heat or cold better than epoxy because it flexes more, and another says failures almost always trace to the slab or the wrong system, not the resin. Ask every bidder how they check the slab and pick the system.
Can my business stay open while an epoxy floor is installed?
Usually only if the work area is fully closed off, because epoxies are dangerous on skin contact and their vapors, mists or particles are harmful to breathe during spraying. We section off the area and keep staff and customers out of it, and if part of the building has to keep running, we'll plan the work in sections with you.
Other floor work we do
Garage Floor Coatings
If you've also got a home garage that needs a floor, we coat those too, with the same testing and grinding before any color goes down.

When your building can't sit closed for days, a polyaspartic coating cures fast enough to get people and equipment back on the floor sooner.

Before any new coating, or after pulling up old tile and glue, grinding opens the concrete and knocks down high spots so the next floor bonds.

Commercial epoxy floors in Martinez and nearby
Inside city limits, the Martinez Building Department issues building permits to owners and licensed contractors, and new applications now go through the city's online portal. We don't assume either way on whether your coating job needs one, so we sort out with you which office covers your address and who pulls it, then work with that office from there. The city also lists a business license as required for contractors working in Martinez.
We take jobs across Contra Costa and Solano counties, and the shop and warehouse floors we see in Concord and Benicia look a lot like the ones in Martinez, with hairline cracks, old coatings and years of spills worked into the concrete. Standard epoxies are fairly rigid, so a slab that's cracking or shifting can pass that stress into the coating unless the system flexes, which is why we check every crack before we choose.
