Epoxy Calculator
Knox Epoxy Pros is an epoxy flooring and concrete coating company serving Knoxville and East Tennessee. Enter your garage dimensions to get square footage, how much coating the floor needs, and an installed price range by system.
Typical Knoxville garages
| Garage | Square feet | Coating | Flake epoxy installed |
|---|---|---|---|
| 1-car garage | 240–300 | 2–3 gal | $1,200–$3,000 |
| 2-car garage | 400–500 | 4 gal | $2,000–$5,000 |
| 3-car garage | 600–750 | 5–6 gal | $3,000–$7,500 |
Coverage assumes roughly 125 square feet per mixed gallon for a professional two-coat build with a wear topcoat. A big-box kit claims more coverage per gallon because it goes on thinner, which is the same reason those floors commonly fail inside two to three winters in Tennessee humidity.
Common questions
- How much epoxy do I need for a 2-car garage?
- A typical Knoxville 2-car garage is 400 to 500 square feet. At roughly 125 square feet per mixed gallon for a professional two-coat build plus topcoat, that is about 4 gallons of coating. Thin DIY kits claim more coverage per gallon because they go on thinner — which is also why they fail sooner.
- How do I measure my garage floor?
- Measure the width and the depth in feet at the widest points, then multiply. Do not subtract for the car; the whole slab gets coated. If the garage is an irregular shape, split it into rectangles, work out each one, and add them together.
- Is the price this calculator gives me a quote?
- No. It is a planning range built from real Knoxville installed prices by system. The final number depends on the condition of your concrete — crack repair, joint work, or grinding off an old failed coating all add labor before any new coating goes down. An exact price needs an on-site look at the slab.
