The formula behind every price
The total is (the system rate + the slab surcharge) × the square feet, plus flat options. The calculator on the home page uses exactly this arithmetic for a garage, and so do the worked examples.
| System | Per sq ft, installed |
|---|---|
| Solid color epoxy | $4–$7 |
| Flake (chip) epoxy | $6–$9 |
| Polyaspartic flake | $8–$12 |
| Metallic epoxy | $9–$13 |
Where the numbers come from
No East Bay price list exists, so the Antioch band starts from California guides: solid color around $3–$8, chip and flake $5–$9, metallic $8–$12 and up, polyaspartic $6–$12, and notes in several that Bay Area contractors charge more than the Central Valley. A third-party estimate for Antioch epoxy garage floors is $6–$10. The bands here are rounded inside those figures.
Size changes the total, not much else
| Garage | Area | Flake epoxy | Polyaspartic flake |
|---|---|---|---|
| 1-car | about 240 sq ft | $1,440–$2,160 | $1,920–$2,880 |
| 2-car | about 420 sq ft | $2,520–$3,780 | $3,360–$5,040 |
| 3-car | about 704 sq ft | $4,224–$6,336 | $5,632–$8,448 |
Typical garage dimensions come from published averages: about 240 square feet for one car, between 360 and 480 for two and about 704 for three.
What the slab adds
| Slab condition | Added per sq ft |
|---|---|
| Sound slab | $0 |
| Minor cracks, pits or spalls | $1–$2 |
| Old coating or paint to remove | $2–$6 |
| Heavy oil or a soft, uneven slab | $1–$2.50 |
On a 420 square foot flake floor, an old coating adds roughly $840–$2,520. The slab is where most bids drift apart.
Options, one by one
Extra crack repair runs about $50–$200 per area. A moisture-vapor barrier primer adds roughly $400–$1,000 for a typical garage. A stem wall, garage steps, a custom flake blend and moving the contents are smaller flat lines. A bid that rolls all of these into one number cannot be compared with one that lists them. These are market estimates, not quotes.
