Straight answer first, then the breakdown — what each system actually costs per square foot, what surface prep adds, and why the quote you get may land above or below the range.

Flake systems sit at the low end. Metallic and quartz sit at the top. Surface prep adds $1–$3 per square foot on most jobs.

Price Per Square Foot

What each system costs

These are installed prices — material and labor — for the systems we put down across Southern California. Surface prep is quoted on top, because a clean slab and a slab with a failed coating on it are not the same job.

Ranges reflect typical Southern California installs. Jobs in Los Angeles, San Francisco and San Diego trend toward the upper end on labor. Systems marked quoted individually vary too much by spec and exposure to publish a useful range — ask us for a number and you'll have one within a business day.

Estimate Your Floor

Work out your range

Pick a system, enter your square footage, and tell us honestly what the slab looks like. You'll get a range — not a single number, because anyone quoting you a precise figure sight-unseen is guessing.

What Moves the Number

Five things that change your quote

+$1 – $3 / sq ft

Surface prep

Diamond grinding, crack and spall repair, and moisture barrier where the slab needs one. This is the line item people try to cut, and it's the one that decides whether the floor is still down in five years.

Varies by system

What you put down

A flake floor and a metallic floor are different amounts of material, labor and skill. Flake is the value pick for a garage; metallic is a finish you choose because you want to look at it.

Lower per sq ft

Size of the job

Bigger floors cost less per square foot — mobilization, grinding setup and cure time are largely fixed. A single-car garage carries a minimum labor charge that pushes its per-foot rate up.

Metro premium

Where you are

Labor runs higher in Los Angeles, San Francisco and San Diego. Corona and the wider Inland Empire generally price below coastal metros for the same spec.

Worth paying for

Who installs it

Crews using high-end product and backing the work with a warranty charge more. Given that a failed floor means paying twice — once to grind the first one off — that premium usually pays for itself.

Real Numbers

What common jobs run

Full flake system with typical prep — the most commonly quoted combination we install.

Figures assume a flake system at $5.50–$6.50 per square foot plus $1–$3 prep. Swap the system in the calculator above to see metallic or quartz.

Getting Value

How to spend it well

  • Get multiple quotes — and make sure they're quoting the same prep. A cheap bid usually means someone skipped the grinder.
  • Don't over-buy the system. If a solid color does the job, a metallic floor is money spent on looks you may not need.
  • Do over-buy on high-traffic space. Flake or quartz in a busy area saves you maintenance and a recoat later.
  • Ask what happens if it fails. A warranty is only worth what the installer is still around to honor.
  • Ask whether they moisture-tested. If the answer is no, the number you're being quoted isn't real yet.
Common Questions

Epoxy cost questions

How much does it cost to epoxy a 2-car garage in California?

A typical 2-car garage runs about 400 square feet. With a full flake system at $5.50–$6.50 per square foot plus $1–$3 for surface prep, most 2-car garages land between roughly $2,600 and $3,800 installed. A metallic finish on the same floor moves that to roughly $4,400–$6,800.

Why is epoxy flooring quoted per square foot?

Because material and labor both scale with area. It also makes bids comparable — but only if the prep is specified. Two quotes at the same per-foot rate can be very different jobs if one includes diamond grinding and moisture mitigation and the other doesn't.

Is epoxy flooring cheaper than tile or polished concrete?

Usually cheaper than tile once you account for installation and grout maintenance, and comparable to polished concrete depending on the finish level. The bigger difference is service life under traffic — epoxy and polyaspartic systems handle hot-tire pickup and chemical spills that would ruin most alternatives.

What makes an epoxy quote come in higher than the range?

Almost always the slab. A failed coating that has to be ground off, deep oil contamination, significant spalling, or a moisture reading that calls for a vapor barrier will all push a job above the published range. We test rather than guess, and we tell you before the work starts, not after.

Do you give exact prices over the phone?

We'll give you a range over the phone and an itemized number in writing after we've seen the slab. Square footage, condition and prep move the figure too much for a phone quote to mean anything. For most local jobs we walk the site, check the profile and test for moisture before committing.

Does a bigger floor really cost less per square foot?

Yes. Mobilization, equipment setup and cure scheduling are close to fixed costs, so they spread across more area on a large job. A 10,000 square foot warehouse will price well below a 250 square foot garage on a per-foot basis for the same system.
