Epoxy Flooring Cost Calculator
Your floor
Estimate only — actual quotes vary by region, installer, floor condition and product. Prices are typical US 2026 installed ranges.
Example: a 500 sq ft garage with solid epoxy on a floor in good condition → about $2,750, typically $2,000–$3,500.
Behind the numbers
How epoxy flooring cost is estimated
The headline figure uses the midpoint of the typical installed price range for your coating, adjusted for floor prep: a floor in good condition uses the range as-is, light prep adds 10% for diamond grinding, and heavy prep adds 25% for grinding plus crack and spall repair. The low and high estimates use the ends of the same range, so you can see what local quotes should fall between.
Worked example: 500 sq ft × $5.50 per sq ft (the midpoint of $4–$7 for solid epoxy) × 1.00 (good condition) = $2,750. The typical range is 500 × $4 = $2,000 to 500 × $7 = $3,500.
Typical installed prices, US 2026
Midpoints used for the headline estimate: water-based $4, solid $5.50, metallic $9.50, polyaspartic $7 per sq ft. Prep factors: good condition 1.00, light prep 1.10, heavy prep 1.25.
Examples
Example epoxy flooring costs
| Floor | Coating | Prep | Estimate | Typical range |
|---|---|---|---|---|
| 500 sq ft | Solid epoxy | Good | $2,750 | $2,000 – $3,500 |
| 400 sq ft | Water-based epoxy | Light | $1,760 | $1,320 – $2,200 |
| 600 sq ft | Metallic epoxy | Heavy | $7,125 | $5,250 – $9,000 |
| 300 sq ft | Solid epoxy | Light | $1,815 | $1,320 – $2,310 |
| 800 sq ft | Polyaspartic | Good | $5,600 | $4,000 – $7,200 |
Tips before you buy
Get at least three local quotes for the same coating and prep level — installed prices vary a lot by region and installer.
Never skip the prep to save money: epoxy peels off a smooth or dirty slab, and a failed coating costs more to remove and redo than the prep would have.
Metallic epoxy looks striking but costs the most and shows every flaw in the slab, so it needs the best prep of any coating here.
Ask whether the quote includes a topcoat and how many coats — a single thin coat wears through far faster than a proper two-coat system with a clear topcoat.

Frequently asked questions
What does the estimate include?
Materials and installation labor at typical US 2026 prices. It does not include moving vehicles and stored items out of the garage, repairing a badly damaged slab, or premium extras such as decorative flakes, logos or a urethane topcoat, which are usually quoted separately.
How long does epoxy flooring last?
A professionally installed solid epoxy floor typically lasts 5 to 10 years in a garage, and longer in light-use rooms. Water-based epoxy wears faster at 3 to 5 years, while polyaspartic topcoats resist UV yellowing and hot-tire pickup better than standard epoxy.
Why does floor prep change the price?
Epoxy only bonds to a clean, rough, dry slab. Grinding the surface and repairing cracks and spalls takes labor and equipment, so a floor that needs heavy prep costs more per square foot than a smooth floor in good condition.
Water-based or solid epoxy — which should I choose?
Solid epoxy is thicker, tougher and longer-lasting, and it is the usual choice for garages. Water-based epoxy is cheaper, thinner and easier to apply, so it suits basements and low-traffic rooms where wear is light.
