Polyaspartic floor systems we put down

  • Full flake garage floor

    A base coat with color flakes scattered across it and a clear polyaspartic topcoat over them, the usual pick for a garage since it hides dust and gives some grip.

  • Solid color with clear top

    A tinted base under a clear polyaspartic topcoat for one smooth, even color, a good fit when you want a clean, simple look in a garage that gets sun.

Is a polyaspartic coating right for my garage floor?

A polyaspartic floor coating in Martinez, CA is a polyurea-type coat we lay over your concrete garage floor so it stands up to tires, spills and afternoon sun without yellowing.

Most calls I get about it start with a garage floor that's peeling, soaked with oil or dusting up, often from someone who wants the garage back fast and has heard polyaspartic handles sun better than standard epoxy floor coatings. What moves the price is the size of the floor, how much grinding and crack repair the slab needs, whether an old coating has to come off and the finish you pick, and the schedule turns on what the slab shows once it's ground and how long the product needs before you drive on it. I give you your own figure in a written estimate after I see the floor.

Polyaspartic coatings start with the slab underneath

I look at the slab first, because a floor that peels usually started with concrete nobody tested or ground right, so the prep we plan depends on what your floor shows us.

  • Choosing the right coating

    A swirled decorative look can point to metallic epoxy flooring and a wet, hot shop to urethane cement flooring, so we settle that first.

  • Asking about oil stains

    We ask where cars have dripped and sat, because oil that's soaked deep into concrete usually won't come all the way out and can keep the coating from bonding.

  • Grinding and repairs

    Our crew grinds the whole slab and fills cracks and pits, so the surface is open, clean and ready for the coating to grab.

  • Base, color and topcoat

    We roll the base coat, scatter color flakes if you picked them and finish with a clear polyaspartic topcoat that stands up to sun.

Why Martinez homeowners call Stonefield

Polyaspartic questions from Martinez homeowners

How long does a polyaspartic garage floor take before I can park on it?

Anywhere from a day to a week, depending on the product and the season. One guide says cars can use the floor within 24 hours, while one maker's topcoat instructions say to keep cars off at least 3 days in summer and 1 week in winter. We give you the figure for the product we use, so you can line up somewhere else to park before we start.

How much does a polyaspartic floor coating cost in Martinez, CA?

Your price comes from the size of the garage and the shape the slab is in, so I give you a figure in a written estimate after I see it. Heavy grinding, lots of crack repair, an old coating to strip or a moisture problem push it up, and a clean, sound slab keeps it down. Full flake and solid color finishes also price differently.

Does my garage slab need a moisture test before a polyaspartic coating?

It's worth doing, because ground-level slabs give off moisture vapor, and one maker warns that too much can make the coating blister and peel loose. That maker advises a calcium chloride test to measure the vapor coming up through the slab, plus a vapor control layer when levels run high, which adds a step before coating. Grinding comes first either way, so ask any contractor whether their quote includes it.

Can polyaspartic go over an old epoxy garage floor?

Only if the old coating is still stuck down tight, since one maker says a new coating holds only as well as the old one holds to the concrete under it. If the old layer is lifting, peeling or soft in spots, stripping the old coating usually comes first, and that changes the prep and the price. I check how well yours is holding when I look at the floor.

How long does polyaspartic last compared to epoxy?

One California guide puts a full polyaspartic system at 15 to 25 years and a two-coat epoxy floor with a polyurethane topcoat at 10 to 15 years. Those are estimates, and how long any floor lasts still comes back to the prep under it and how hard it's used. If you're weighing the two, set the longer life against what each costs you up front.

How do I take care of a polyaspartic garage floor?

Dust mop it, clear off grit and debris, and clean it on a regular schedule. One maker says that routine care is what keeps the floor looking right and gets you its longest life, since grit tracked in on tires and shoes slowly wears the topcoat. I go over the details when I walk the finished floor with you.

Polyaspartic floor coatings around Martinez

Inside Martinez city limits, building permits come from the city's Building Department, which issues them to homeowners and licensed contractors, and whether a garage floor coating needs one is a question for that office, not a guess. If your job needs a permit, we sort out with you which city or county office covers your address and who pulls it, then work with that office from there. You can also call the Martinez Permit Center on its permits line, (925) 372-3515, Monday to Friday from 8 to 11:30 a.m. and 1 to 4 p.m.

In California, local air districts limit the volatile organic compounds, the solvents that evaporate as a coating cures, in coatings like these, so what we put down has to fit the rules where you live. Most garages we see are attached ones with years of oil drips and a tired old finish, and we find the same on jobs in Concord, Benicia and the other cities around Martinez in Contra Costa and Solano counties.
