Straight multiplication of the published range — real quotes shift with waste (carpet rolls seam differently than rooms measure), prep, stairs, and removal. The calculator does the real material math.
What moves the price
| Cost factor | Why it matters |
|---|---|
| Coating system | Basic epoxy sits at the low end; UV-stable polyaspartic and multi-coat hybrid systems (base + flake + clear top coat) sit at the top. |
| Concrete prep & condition | Diamond grinding is standard; crack and spall repair, moisture mitigation, or old-coating removal add real cost — prep is most of the labor. |
| Finish style | Solid color is simplest; full-flake broadcast adds material and a clear coat; metallic and quartz finishes are the premium tier. |
| Floor size & layout | Bigger floors cost less per square foot. Tight thirds-of-a-garage jobs carry minimum-job pricing. |
| Extras | Steps, stem walls and cove edges, aprons, and anti-slip additive are priced as add-ons. |
| Cure-time tier | One-day polyaspartic installs command a premium over multi-day epoxy schedules. |

Frequently asked questions
How much does coating a 2-car garage cost?
A 2-car garage is roughly 450 to 500 square feet. At about 4 to 10 dollars per square foot installed, that is around 2,000 to 4,500 dollars for a professional full-flake system, including grinding and a clear top coat.
Why not just use a DIY epoxy kit?
Store kits cost a few hundred dollars but skip the step that makes coatings last: mechanical diamond grinding. Without it, hot-tire pickup and peeling are common within a year or two. Professional systems are thicker, UV-stable, and usually carry long warranties.
What should the quote include?
Ask for grinding/prep, crack repair, moisture check, the named system (epoxy, polyaspartic, or hybrid), the finish (flake, solid, metallic), edges and steps, and the cure schedule — each as its own line item.
