Concrete sealing in Antioch CA - a slab that sheds water and resists stains
Faded concrete that darkens every time it rains or holds every oil drip? We seal it so water and stains stay on top instead of soaking in.
Should I seal my concrete in Antioch?
Concrete sealing in Antioch, CA puts a protective sealer on your driveway, patio, walkway or stamped concrete so water and stains stay on the surface instead of soaking into the slab. Sterling Antioch Concrete Coatings is based in Antioch and seals concrete here and in the cities around it.
Most calls start the same way. The patio looks faded, rain leaves the driveway dark for hours, or a drip from the car has soaked in for good, and you want the next one to wipe up. The price moves with how much concrete there is, whether old sealer has to come off first, and whether the slab is stamped, since texture and grooves take more care. The schedule turns on how new the slab is, how long it takes to dry after washing, and what time of day the sealer can go on. I look at the slab, ask how you use it and give you a written estimate, so you have your own number before anything is booked.
How we handle concrete sealing
At the estimate I look at the slab and whatever is already on it, then I ask what look you want, because that's what decides the sealer. If your concrete was sealed before, I'll tell you plainly whether it's due yet, since piling coat on coat makes a mess that's hard to get off later. On the day, our crew contains the wash area before any water runs, so it stays out of the street and the storm drain. Then we clean the slab, strip off any sealer that's failing, blow standing water out of the saw cuts, the grooves cut across the slab, and give the concrete time to dry before the sealer goes on.
Sealer protects good concrete, but it won't fix a worn surface. When a slab is scaled, pitted or full of patches, sealing just locks that in, so we'd talk about concrete resurfacing and overlays first. If an indoor or garage slab is uneven, self-leveling concrete and overlays bring it flat before any finish goes on.
Why people in Antioch hire us to seal their concrete
The owner writes your estimate
I come out myself to look at the slab and write the estimate, and I run the job with our crew. The person who told you what the work involves is the one watching how it gets done.
In business since 2013
I started this business in 2013 after learning floor coatings from an installer in East Contra Costa. Thirteen years of looking at slabs is why I'd rather test a floor than guess about it.
Wash water kept out of drains
Contra Costa County's guidance says pressure-washing water has to stay out of the storm drain, and it holds you responsible for what the contractor you hire lets run off. That's why containing the wash area is the first thing we set up, before the washer ever starts.

What people ask about concrete sealing
What type of sealer is best for stamped concrete?
A film-forming sealer is the most common pick for stamped concrete when you want richer color, because it coats the surface and deepens the tones. A penetrating sealer still keeps water and stains out, but most leave the color looking the way it does now. If you like your concrete's color as it is, penetrating is the quieter choice.
How long do I have to wait to seal new concrete in Antioch?
The concrete industry's standard for a full cure is 28 days. The time your slab actually needs varies with where it is, the time of year and the sealer going on it, so plan the sealing date around both the cure and the sealer you choose. We'll go over that at the estimate.
How often should stamped concrete be resealed?
Reseal stamped concrete when it shows it's due, not on a set number of years. The signs are water and stains soaking in instead of sitting on top, or color that has lost its depth. If you're not sure, I'd want to splash some water on it and look before you pay for another coat.
How much does it cost to seal a concrete driveway or patio in Antioch?
There's no flat price, because it depends on your slab. The size, whether old sealer has to be stripped, how deep the stamped texture is and which sealer you pick are what move it, and any repairs add to it. The free on-site estimate puts the number for your slab in writing.
How do I get old flaky sealer off my concrete?
Loose, flaky or discolored acrylic sealer comes off by sand or soda blasting, a high-pressure washer or a chemical stripper, and the slab is cleaned thoroughly before new sealer goes on. One coatings maker's guide checks for a cure-and-seal product with a dime-sized bead of water, which should soak in within five or 10 seconds. When the water stays on top, that guide strips the slab bare before sealing.
What is the best time of day to seal concrete in summer?
Usually the evening. A good rule for resealing stamped concrete is to apply sealer when the slab's temperature will be falling, not rising, for 3 to 4 hours after, and in summer that often means a later start than most jobs.
Other concrete work you might need
- Concrete Resurfacing & Overlays
If your slab is scaled, pitted or covered in old patches, a resurfacing overlay gives you a fresh, even top layer that's worth sealing afterward.
- Self-Leveling Concrete & Overlays
When a garage or interior floor dips, slopes or has humps that trip people up, a self-leveling overlay flattens it so the next coating or finish sits evenly.
