Epoxy Flooring Cost Calculator
A resin floor runs $5 a square foot on a 20 × 20 garage in Atlanta and $4 on a 2,000 sq ft floor, because three of the visits it takes do not get smaller when the floor does. ⚠️ Resin is sold by the gallon, and coverage is arithmetic: 1,604.17 square feet per gallon per mil of film. A kit at 48% solids leaves 3 mils; a 100% solids epoxy leaves 10.

⚠️ Nothing here tests the slab. A floor poured on grade without a vapour retarder under it pushes moisture upward for ever and lifts any coating off from the middle outward, and the only way to know before you buy the resin is to measure. Tick the moisture test above: it is the cheapest line on the page relative to what it can save.

How much resin, and why the answer is arithmetic
A gallon spread one mil thick covers 1,604.17 square feet — that is 231 cubic inches divided by a thousandth of an inch. Everything below follows from that, the solids in the tin and the film the system is applied at.
| System | Film | Coverage | Your floor | Cost |
|---|---|---|---|---|
| Water-based epoxy kit, the one on the shelf48% solids | 3 mils | 229 sq ft/gal | 1.75 gal | $1,864$4.66/sq ft |
| 100% solids epoxy, two-part100% solids | 10 mils | 143 sq ft/gal | 2.8 gal | $2,192$5.48/sq ft |
| Polyaspartic, base and topcoat90% solids | 8 mils | 161 sq ft/gal | 2.48 gal | $2,413$6.03/sq ft |
⚠️ Google shows “how much epoxy for a 1000 sq ft floor” on this search, and it is a question about quantity that no cost page answers. Here it is: 6.99 gallons of 100% solids epoxy for a thousand square feet, against 4.37 of the water-based kit — and the kit is not cheaper because it goes further, it goes further because there is less in it. Half of that tin evaporates.

Over its life the dearest system is the cheapest: Polyaspartic at $138 a year against $621 for the kit off the shelf. ⚠️ Those lives are our estimates and they carry a heavy assumption, stated because the whole table hangs on it: they assume the slab was mechanically prepared. And a number nobody publishes because it moves with the local wage: on your area's rates, shot blasting overtakes grinding at about 925 square feet. Below that the machine costs more to bring than it saves; above it, the opposite.

Where these numbers come from
- Coverage is arithmetic, and it is the whole difference between the products
- A US gallon is 231 cubic inches. Spread one mil thick — a thousandth of an inch — it covers 1,604.17 square feet, and that is a unit conversion rather than a claim. Everything else follows: coverage is 1,604.17 × solids ÷ mils, less what the concrete drinks. So a water-based kit at 48% solids applied at 3 mils covers 229 square feet a gallon, and a 100% solids epoxy at 10 mils covers 143. ⚠️ The kit is not cheaper because it goes further — it goes further because there is less in it, and about half of what you carry home evaporates. Two products sold under the same word, differing by a factor of three in film thickness, is why the prices you find online for “epoxy flooring” range from two dollars a square foot to twelve. Ours are $4, $5 and $6 for the three, on the same floor.
- It fails at the bond, and the bond is the line people delete
- A resin floor almost never fails because the resin broke. It fails because it was never stuck, and what sticks it is the preparation. Acid etch is what comes in the box: it opens the surface unevenly, does nothing to a sealer or a soaked-in oil stain, and barely bites a power-trowelled garage slab. Grinding takes the top off and leaves a uniform profile. On this floor that is $1,831 against $2,098 — a difference small enough to look like a corner worth cutting and large enough to be the whole life of the floor. ⚠️ Grinding concrete is respirable crystalline silica work under OSHA 1926.1153, Respirable crystalline silica (read 2026-08-25), so the shroud and the HEPA vacuum are a legal duty on the contractor rather than an upsell — a quote that grinds dry is telling you something about the rest of it. And a threshold worth knowing: on your area’s wages shot blasting overtakes grinding at about 1,250 square feet. Below that the machine costs more to bring than it saves.
- What the cost-per-year table refuses to do
- The comparison people want is cost per year, and this page will give it to you — over a mechanically prepared slab, the polyaspartic works out at $133 a year against $590 for the kit, which is the dearest thing on the page being the cheapest over time. ⚠️ Over an acid etch the table does not appear at all, and that is deliberate rather than missing. Dividing a price by a life means something only if you know the life, and over an etch nobody does: the same tin lasts twelve years on a ground slab and peels in two on a sealed one. Publishing a number there would be inventing the denominator. The other thing that decides the life is underneath the slab rather than on it: a floor poured on grade with no vapour retarder pushes moisture upward for ever and lifts a coating off from the middle outward. The test is $238 here and it is the cheapest line on the page relative to what it can save.
- Two trades, two chemistries and where the numbers come from
- The preparation is concrete work and the coating is painting work, so they are priced from two different official wages rather than averaged into one: BLS OEWS for cement masons and concrete finishers and for painters, May 2025, retrieved 2026-08-20, benefit-loaded from BLS ECEC. ⚠️ Two health notes that belong next to the price rather than in the small print. Polyaspartic is a polyurea chemistry containing isocyanates, which OSHA, Isocyanates (read 2026-08-25) associates with occupational asthma and respiratory irritation. And a garage attached to a house shares air with it, so what is applied in there matters indoors — EPA, Volatile Organic Compounds’ Impact on Indoor Air Quality (read 2026-08-25) is the federal starting point, and the 100% solids systems are the low-solvent ones precisely because nothing has to evaporate. Every estimated band is on the dataset page, the whole approach on the method page, and if what you actually want is a floor covering rather than a coating, our vinyl plank page prices the usual alternative over the same slab.
- Material prices
- Modelled estimates, not sourced prices. No public, machine-readable source of US residential material prices exists, and we would rather say so than pretend otherwise. Each line carries its own uncertainty band. How we estimate them.

What this figure does not include
- Emptying the garage, and not using it for a week
- ⚠️ Everything comes out, and on a full epoxy system the floor is unusable for foot traffic for a day or two and for a car for about a week, because the resin keeps hardening long after it feels dry. Driving on a floor that has not fully cured leaves tyre marks that do not come out. Polyaspartic is the system that shortens this, and shortening it is most of what the extra money buys.
- A slab that is moving
- A resin floor is a coating, not a repair. A crack with a step in it, one that has opened in the last year, or a slab that has settled is a structural question, and it belongs on our foundation repair page. Coating over it hides the evidence and changes nothing.
- Making a wet slab dry
- ⚠️ If the moisture test fails, the honest answers are a moisture-tolerant primer system — which is a different and dearer specification not priced here — or not coating the floor at all. There is no version of this job that seals moisture in from above and lasts.
- Stripping a coating that is already there
- Taking off a failed or peeling coating is grinding work in its own right and it can cost as much as the new floor. It is not in these figures because how much comes off with a scraper and how much has to be ground is not knowable until somebody starts.
Questions people actually ask
How much epoxy for a 1000 sq ft floor?
6.99 gallons of 100% solids epoxy, and it is arithmetic rather than a figure off a tin: a gallon spread one mil thick covers 1,604.17 square feet — 231 cubic inches divided by a thousandth of an inch — so at 100% solids and ten mils of film a gallon does 143 square feet, and the last twelve per cent goes into what the concrete drinks and what stays in the roller. ⚠️ The same thousand square feet takes only 4.37 gallons of a water-based kit, and that is not because the kit goes further: it is because roughly half of what is in the tin evaporates and leaves 3 mils behind instead of ten.
How much does a 20x20 epoxy floor cost?
About $2,098 in Atlanta for a 100% solids epoxy with the slab ground, flake broadcast and a topcoat — 2.8 gallons of resin, and $5 a square foot. ⚠️ That per-square-foot figure is higher than you will see quoted for a big floor and it should be: a resin floor is three visits — prepare, base, topcoat — and the plant and the crew arrive for each of them whatever the size. The same specification over 1,000 square feet is $5 a square foot and over 2,000 it is $4.
How much does it cost to epoxy a 12x12 room?
About $1,046, which works out at $7 a square foot — nearly 1.7 times the rate of a 2,000 sq ft floor for the same specification. ⚠️ Nothing about a small room is dearer per foot except the parts that do not scale: the van, the grinder, the masking and three separate visits. If you have a garage as well as the room, having both done on the same booking is the single biggest saving available on this job, and it is worth asking for as one quote rather than two.
How much does it cost to epoxy 1000 square feet?
$4,568 in Atlanta for 100% solids epoxy, ground, flaked and topcoated — $5 a square foot. A water-based kit over the same floor is $1,771 and a polyaspartic system $2,320. ⚠️ The figure that matters more than any of those is the one underneath: over their lives the polyaspartic works out at $133 a year against $590 for the kit, because the kit is a two-to-four-year floor. And all of that assumes the slab was mechanically prepared: over an acid etch nobody can tell you the life at all.
