Polyaspartic Floor Coatings in Antioch CA - a tough finish over a tested slab
Stained, dusty or peeling concrete in your garage? We grind it, check the slab for moisture and coat it with a hard, easy-to-clean finish.

Is a polyaspartic coating right for your garage floor?
A polyaspartic floor coating is a fast-curing type of polyurea that Sterling Antioch Concrete Coatings puts down over ground concrete in Antioch and the cities around it. It leaves a hard finish that stands up to sunlight, chemicals and scuffing, and because it cures quickly, your garage isn't out of commission for long.
Most people call me because their garage floor is stained, dusty or peeling, or because an old coating let go and they want one that holds this time. If you're still weighing systems, our garage floor coatings page covers the other options. What you'll pay comes down to the size of the floor, how rough the concrete is, which product we use and extras like color flake. The schedule turns on how much prep the slab needs, what the moisture check shows and how long the coating has to cure before you drive on it. I'll put your own numbers on all of that in a written estimate after I've looked at the floor. If your job calls for a permit, I'll tell you at the estimate and we'll settle who gets it before work starts, and when I'm not sure, I check first with the City of Antioch Building Division, which asks people to call or email before they apply.
How we put down a polyaspartic floor coating
This coating doesn't breathe, so any moisture trapped under it has nowhere to go, and that's why the job starts with the slab, not the color chart. We clear and protect the space, grind the concrete to open up its surface, fill cracks and chips, and check the slab for moisture before anything goes on it. If the readings aren't where I want them, we talk about it before we coat, not after. Then we vacuum up the dust, put the coating down in layers and keep fresh air moving the whole time it goes on, and we clean up before we leave so you get your space back the way you'd want it.
Polyaspartic isn't the only finish we put on concrete. If you want a decorative, one-of-a-kind look in a living space or showroom, metallic epoxy flooring is the better fit. For a kitchen, brewery or shop that sees hot water and daily wash-downs, urethane cement flooring is built for that kind of abuse in a way a thinner coating isn't.
Why Antioch homeowners call Sterling Antioch Concrete Coatings for polyaspartic floors
The owner writes your estimate
I come out myself to look at the floor and write the estimate, and I run the job with our crew. The person who checked your slab is the one standing there when the grinder starts.
Coating floors since 2013
We've been in business since 2013, and the lesson that's stuck with me is that a floor's real test comes years later, not the day it's done. So I judge our work by how it holds up and how clean we leave your space.
Licensed and insured on every job
We're licensed and insured. California's contractor license board files resin and epoxy floor work under its synthetic products class, and its list doesn't name polyaspartic directly, so it's fair to ask any crew you're considering how their license covers this work.
On this coating, what decides how long it lasts is the part you'll never see, so the first step is getting me out to look at your slab. Call (925) 503-1069 or request your estimate.

Questions before you book a polyaspartic coating
How much does a polyaspartic floor coating cost in Antioch?
Across the US, a polyaspartic floor coating usually costs about $5 to $12 per square foot, including materials and professional installation. That's a national figure, so where your floor lands depends on what I find at the estimate. You can trim the cost a little by moving everything out of the space yourself, so our crew can get straight to the floor.
How long does a polyaspartic coating take to cure before I can park on it?
Most polyaspartic coatings are dry to the touch within a few hours, and full cure for heavy vehicle traffic typically comes within 24 to 48 hours. Plan to keep your cars out of the garage for that window, and I'll tell you when your floor is ready based on the product we used.
How long will a polyaspartic garage floor last?
When it's properly applied and maintained, a polyaspartic floor in a home can last 10 to 20 years or more. Both halves of that matter, so the prep is on us and regular cleaning is on you. Every job is backed by our satisfaction guarantee.
Why do concrete prep and moisture matter for a polyaspartic floor?
They decide whether the coating stays stuck to the concrete. One maker's guide calls surface prep the key to long-term success and prefers grinding or light shotblasting, because that lets the coating soak into the concrete and grip it. The same maker says its polyaspartic doesn't breathe, so moisture under it builds up until the coating blisters and peels away, which is why I'd want to test your slab before we pick a color.
Is polyaspartic or epoxy better for a garage floor?
For most garages I'd lean toward a full polyaspartic system, because it cures fast and handles the sun that comes in through an open garage door. Some contractors offer a blend of epoxy and polyaspartic layers to bring the cost down, and it does save money, but it may not perform as well as an all-polyaspartic floor. If the budget's tight, ask about it at the estimate and I'll tell you what you'd give up.
How do I get my garage ready for a polyaspartic floor coating?
Move your cars, shelves and anything sitting on the floor out before we arrive, because clearing the space yourself saves money and lets our crew get right to work. Most polyaspartic coatings are very low in VOCs, the solvent vapors that make fresh paint smell, but they can still give off fumes while they go down, so we keep the garage door open and wear protective gear.
Other floors we put down
- Metallic Epoxy Flooring
If you want a floor with depth and movement, like poured stone or swirling metal, metallic epoxy gives a basement, shop or living space a one-of-a-kind look.
- Urethane Cement Flooring
For floors that see hot water, steam cleaning or heavy spills, urethane cement handles heat and wash-downs better than a thin coating, which suits workshops and food prep areas.
