Garage floor coatings in Antioch CA - a finish bonded to sound, clean concrete
Peeling, oil-stained or dusty garage floor? We grind off the weak surface, deal with the oil and lay a coating that grips solid concrete.
What goes into coating a garage floor in Antioch?
Garage floor coatings in Antioch, CA are an epoxy or urethane layer laid over concrete that's been ground, cleared of grease and oil, and checked dry, so you end up with a sealed, finished floor instead of bare, stained concrete.
Most people call us because the old coating is peeling, the floor is soaked with oil drips, or the bare slab sheds dust onto everything stored in the garage. The price moves with the size of the garage, how much grinding the slab needs, how many oil-soaked spots have to be dealt with and whether there's old paint to come off. The schedule turns on what the moisture check shows and how long you can keep the car out while the coating cures. I look at the slab, ask how you use the garage and put it all in a written estimate, and if the job calls for a permit, I'll tell you then and check with the City of Antioch Building Division first when I'm not sure.
How we put down a garage floor coating
I check the slab before we ever talk colors, because the finish is only as good as the concrete under it. On the job, our crew clears the garage and goes after deep oil stains first, since grinding over oil just spreads it around, and I'll have told you at the estimate if a stain needs extra work. Then we grind the whole floor, because when a garage coating peels it often takes the weak top skin of the slab with it, and taking that skin off gives the coating sound concrete to grab. We fill cracks and chips, make sure the slab is dry enough to coat, lay down the base and topcoat, and clean up so the space is ready once the cure allows.
Plain epoxy isn't the only finish that goes over this prep. Polyaspartic floor coatings are another system we put down in garages, and metallic epoxy flooring gives the floor a deep, swirled look for people who want the garage to feel like more than a parking spot. Both go over the same grinding and testing, so the work under the finish stays the same whichever one you pick.
Why Antioch homeowners call Sterling Antioch Concrete Coatings for garage floors
The owner checks your slab
We've been in business since 2013, and I still come out myself to look at the floor and write the estimate, then run the job with our crew. The person who told you how the prep would go is the one making sure it gets done that way.
Licensed and insured in California
California requires a state contractor license for anyone altering a structure when labor and materials total $1,000 or more. We're licensed and insured, so you're hiring a crew that's allowed to do the work and covered while we're in your garage.
Contract and changes in writing
California's contractor law says a home improvement contract has to carry notices that protect you, and any change has to be in writing, easy to understand and tell you about your right to cancel. If the slab turns up a surprise once we start grinding, you'll see the change on paper before we do the extra work.
Your garage left clean
Grinding concrete makes a lot of fine dust, and I judge our work partly by how clean we leave the space. You get your garage back ready to use, not covered in grit from the prep.
On a garage floor, the work that counts is the grinding and testing under the coating, because that's what holds it to the slab. Call (925) 503-1069 or send us your garage details with the rough size, any old paint or oil stains, and when the car can stay out.

We reply to every call and message within one business day. I'll set a time to come out, look at the slab, ask how you use the garage and give you a written estimate, free and with no obligation. If you can, tell us roughly how big the garage is, whether there's old paint or oil stains, and when the car can stay out.

Questions before you book a garage floor coating
How much does a garage floor coating cost in the Bay Area?
Epoxy floor coating in the Bay Area usually costs about $7 to $10 per square foot, and that covers materials, floor prep and application. That's the going rate around here, not our price, and where a garage lands depends mostly on how much prep the slab needs. I'll give you your own figure in writing after I've seen the floor, and our work is backed by our satisfaction guarantee.
What causes a garage floor coating to peel?
Most often the coating was laid over laitance, the weak, powdery top layer of the slab, and when that layer lets go it takes the coating with it. Grinding or shotblasting removes that layer, so how an installer plans to prep the floor is one of the most important lines in any quote you get.
Can a garage slab that looks dry still ruin an epoxy coating?
Yes, a slab can feel bone dry and still hold enough moisture inside to lift a coating within months. The coating maker's data sheet sets how much moisture is acceptable, so I'd want to test the slab against that limit, and the result decides when coating can start.
How do I deal with deep oil stains or old paint on my garage floor in Antioch?
Oil and other contamination have to come out before the floor is ground, and concrete that's heavily oil-soaked sometimes has to be cut out entirely, which can change the plan and the price. Old paint is its own concern, because one paint maker warns that scraping, sanding or removing it may release lead dust, which is toxic. Tell us about either one when you reach out so I can look at those spots when I come out.
How long does it take before I can park on a new garage floor coating?
One coating seller's guide puts light foot traffic at about 6 to 8 hours after the topcoat and cars typically at 2 to 3 days. Once it's cured, a coating is less likely to show tire marks than a cure-and-seal product, though marks can still happen.
Are epoxy garage floors slippery when wet?
They can be, because epoxy coatings can be slippery, but granular material can be added to make the surface less slick. If cars bring in rain or you hose the garage out, mention it at the estimate and we'll plan for the added grip.
Other floors we put down in garages
- Polyaspartic Floor Coatings
Ask about a polyaspartic coating if you want another option for the garage floor, laid over the same ground and tested slab and talked through with you at the estimate.
- Metallic Epoxy Flooring
Pick metallic epoxy if you'd like the garage floor to have a deep, swirled finish that reads more like a showroom or a home bar than a parking spot.
