Epoxy floor coatings for homes and shops

  • Garage and home floors

    A coating over the concrete in your garage, basement or utility room that stands up to tires, spills and foot traffic and wipes clean.

  • Shop and business floors

    Epoxy for working shops and commercial spaces where carts, equipment and spills are part of the day, planned around how long you can be closed.

Is my concrete ready for an epoxy floor coating?

An epoxy floor coating in Martinez, CA goes over your existing concrete to protect it or give it a decorative finish, and it holds only as well as the slab under it was tested and prepped.

Most people call us because the garage floor is soaked with oil, a shop floor is wearing through, or a coating someone else put down is lifting and needs us to strip the old coating first. Whether your slab is ready comes down to moisture, cracks and what's soaked into it, and those same things move the price along with the size of the floor and the finish you pick. The schedule turns on how much prep the slab needs, whether the concrete is new, and how long the coating has to cure before you can use the space again. I'll give you the figure for your floor in a written estimate once I've seen it.

Epoxy coatings and the prep under them

We decide what your floor needs from the slab up, whether it's a home garage floor coating or commercial and industrial epoxy for a working shop, because the concrete decides how well any coating holds.

  • Moisture check first

    We check how much moisture the slab is holding before anything else, because a damp slab is where most peeling floors start.

  • Cracks and stains fixed

    We fill cracks and chips and clean out oil and other stains, since the coating only sticks as well as the surface under it.

  • Grinding the surface

    Our crew grinds the concrete so the epoxy has clean, open pores to grab, which a mop and degreaser alone won't give you.

  • Coating and curing

    We lay down the coating in the finish you picked, keep the space ventilated, and stick to the keep-out time we gave you upfront.

Why Martinez owners call Stonefield for their floors

I learned floor coatings on my own garage and beside experienced crews, and what stuck with me is that a peeling floor usually starts with a slab nobody tested or ground right. So we spend our time on prep, and I tell you what we'll do and why before you sign.

  • I come out to see the floor myself

    I look at your slab and write the estimate myself, and I'm on the job with our crew during prep and install, so the person who planned it is there while it gets done.

  • Coating concrete since 2017

    We've been in business since 2017, and the floors we're best known for are the ones that stay bonded, from home garages to working shops.

  • Licensed and fully insured

Epoxy floor questions we hear

What causes epoxy floors to peel, and how do you prevent it?

Most peeling comes from coating concrete that's damp or giving off a lot of moisture vapor, a failure called delamination where the coating lets go of the slab. The usual advice is to measure the slab's relative humidity, its moisture level, before coating, so ask any contractor for that reading before work starts. A dirty, cracked or stained surface weakens the bond too, which is why repair and cleaning come before the coating on our jobs.

How long does an epoxy floor take to cure before I can use it?

The coating typically takes 24 to 48 hours to cure, and during that time people should be out of the house or well away from the area while it stays ventilated. Several days may pass after that before the floor is ready for regular traffic, so plan where everyone will stay and where the cars or equipment will go.

How much does an epoxy floor coating cost in Martinez?

Installed epoxy floor coating across the US usually costs about $3 to $12 per square foot. That's a national range for the coating put down, not our price, and where your floor lands depends on its size, how much prep the slab needs and the finish you pick. For a Martinez figure, I'll look at your floor and give you a written estimate.

Can you put epoxy on new concrete?

Yes, but newly poured concrete generally gets about 30 days to cure before it's coated, though much faster cure times can be reached when a schedule calls for it. If your slab was just poured, tell me the pour date so we can plan the coating around it.

Does epoxy turn yellow in the sun?

Some epoxy coatings discolor over time in sunlight, so it matters if your floor gets direct sun, like a garage that sits with the door open on summer afternoons. Tell me about the light in the space when I come out so we can factor it into the plan.

What do I do with leftover epoxy in Martinez?

Call the county's Central County Facility at (800) 646-1431 and ask how to handle it, since it serves Martinez residents. Some epoxy components can be hazardous before they cure, while cured epoxy is usually safer to handle, so treat unmixed cans with care until you've asked.

Epoxy floor coatings in Martinez and nearby cities

Inside Martinez city limits, the city's Building Department issues building permits to homeowners and licensed contractors, so that's who to ask whether your floor needs one. If it does, we sort out with you which city or county office covers your address and who pulls the permit, then work with that office from there. One state rule is worth knowing when you compare bids: California lets someone without a contractor license take on work under $1,000 only when it needs no permit and they have nobody working for them on the project.

We're based in Martinez and take jobs in the cities around it in Contra Costa and Solano counties, and what we see most is older garage slabs with years of oil soaked in or a store-bought coating coming up in patches. We run into the same floors on jobs in Concord and Benicia, and they get the same deep cleaning and grinding before anything goes on top.
