Epoxy flooring costs $3–$7 per square foot installed for the system most homeowners are quoted — an epoxy base, a full vinyl flake broadcast and a polyaspartic clear topcoat. Plain mid-grade epoxy comes in at $3–$5, high-solids or 100% solids epoxy at $4–$7, full polyaspartic systems at $5–$10, and decorative metallic epoxy at $8–$15. Doing it yourself, materials run from about $0.30 per square foot for a big-box kit to $1.75–$3.00 for a high-solids system that will actually last.
The per-square-foot figure moves with three things that a headline price hides: how the concrete is prepared, how thick the finished film is, and how big the job is. A 120-square-foot laundry room can cost more per foot than a 1,000-square-foot shop, because the crew, the grinder and the day are the same either way. This guide covers every common use — garage, basement, kitchen, patio and commercial — and gives you a worksheet to estimate your own floor before you call anyone.
Cost by System Type
"Epoxy floor" covers products that differ tenfold in what they deposit on the concrete. These are the 2026 ranges for each category, materials-only and professionally installed, along with the service life you can realistically expect under normal residential use.
| System | Materials / sq ft | Installed / sq ft | Realistic life |
|---|---|---|---|
| Epoxy + full flake + polyaspartic topcoat | $2.50 – $4.50 | $3 – $7 | 10 – 20 years |
| Big-box epoxy kit (water-based) | $0.30 – $0.80 | DIY only | 2 – 4 years |
| One-part epoxy-acrylic paint | $0.25 – $0.60 | $2 – $4 | 3 – 5 years |
| Mid-grade epoxy (50–70% solids) | $0.80 – $1.75 | $3 – $5 | 5 – 8 years |
| High-solids / 100% solids epoxy | $1.75 – $3.00 | $4 – $7 | 8 – 15 years |
| Full polyaspartic / polyurea | $3.00 – $7.00 (hard to DIY) | $5 – $10 | 15 – 20+ years |
| Metallic epoxy (decorative) | $3.00 – $6.00 | $8 – $15 | 10 – 15 years |
| Acrylic concrete paint (for comparison) | $0.15 – $0.50 | $2 – $4 | 2 – 4 years |
Two things stand out. First, the cheapest products are not much cheaper to have installed, because labour and preparation dominate a professional price — a contractor's cost for a thin one-part coating and for a proper high-solids system differs by perhaps a dollar a foot, while the life differs by a decade. Second, the flake-and-topcoat system sits in the same installed band as plain high-solids epoxy, which is why it has become the default residential specification. The flake hides dust and imperfections, and the topcoat takes the wear. The epoxy flake flooring guide covers broadcast density and chip sizes in detail.
Full polyaspartic and polyurea systems cost more and cure in hours rather than days, which is most of what the premium buys. If you are weighing that upgrade, the polyaspartic floor coating cost breakdown goes through it line by line.
Cost by Room and Use
The same chemistry gets priced differently depending on where it goes, because each room brings its own preparation problems, access constraints and performance demands.
| Room / use | Usual system | Installed / sq ft | Typical project |
|---|---|---|---|
| Garage | Epoxy + flake + polyaspartic topcoat | $3 – $7 | $1,500 – $3,500 (2-car, 500 sq ft) |
| Basement | High-solids epoxy or flake, often with moisture primer | $4 – $8 incl. mitigation | $3,000 – $7,500 (800 sq ft) |
| Kitchen / living space | Metallic or solid-colour epoxy + urethane topcoat | $6 – $15 | $1,500 – $4,500 (200–300 sq ft, minimums apply) |
| Workshop / home gym | High-solids epoxy, flake optional | $4 – $7 | $2,500 – $6,000 (600–900 sq ft) |
| Patio / outdoor slab | Not recommended for epoxy | — | Use a UV-stable coating or stain instead |
| Commercial / industrial | Broadcast, mortar or urethane-cement systems | Several dollars to $12+ | Varies with thickness, prep and downtime |
Garage
The most common epoxy project and the most competitive market, which keeps garage prices in the $3–$7 band for a full flake system. Garages need hot-tire resistance, oil and salt resistance, and a surface that hides dirt, so flake and a polyaspartic topcoat are the norm rather than an upsell. We have a dedicated epoxy garage floor cost guide with figures by garage size, a day-by-day job timeline and cost-per-year comparisons, so rather than repeat it here: expect $900–$2,200 for a one-car garage, $1,500–$3,500 for a two-car, and $3,000–$7,000 for a four-car or shop-sized space.
Basement
Basements cost more per square foot than garages for one reason: moisture. Basement slabs sit below grade, and many older ones were poured without a vapour barrier. An impermeable epoxy over a slab pushing moisture will blister and delaminate, so a competent installer tests first — a calcium chloride or in-slab relative humidity test — and prices a moisture-mitigating epoxy primer or vapour barrier system where the numbers call for it. That adds $1–$3 per square foot, which is why a basement often lands at $4–$8 rather than $3–$7.
Access is the second factor. Grinders, dust extractors and material all have to come down a staircase, and there may be a furnace, water heater, support posts and a sump pit to work around. Basements also tend to have more cracks and patched areas than garages. On the other side of the ledger, a finished basement does not see vehicle traffic, so a solid colour with a urethane or polyaspartic topcoat — skipping flake — is a reasonable way to keep costs down in a storage or utility space. If moisture testing comes back high and you do not want to pay for mitigation, a breathable basement floor paint is the honest fallback.
Kitchen and Residential Interiors
Epoxy in living spaces is almost always a decorative choice — metallic swirls, solid colour with a satin urethane, or a fine flake — and it is priced as skilled finish work at $6–$15 per square foot. Metallic floors in particular depend on how the installer manipulates the pigment while it is wet, so experience matters more than in any other epoxy job, and the cheapest bid is rarely the one to take.
Interior jobs also carry costs that garages do not. Epoxy needs a concrete slab, so existing tile, vinyl or carpet has to come out first, and tile removal with adhesive grinding can add a few dollars a foot on its own. A wood subfloor is generally not a suitable substrate for a residential epoxy system without a cementitious overlay first. Cabinets, toe-kicks and door casings need careful masking or trimming, and the room is out of use for several days while the coating cures. Many kitchens are only 150–300 square feet, which pushes the job straight into minimum-charge territory. The result is that a small kitchen floor commonly costs $1,500–$4,500 even though the material quantity is modest.
Before committing to epoxy in a living space, it is worth reading the disadvantages of epoxy flooring: it is hard and cold underfoot, slippery when wet without an aggregate, and difficult to repair invisibly if you drop something heavy on it.
Patio and Outdoor Concrete
Epoxy is the wrong product for a patio, and a contractor who quotes it without caveats is telling you something. Standard epoxy is not UV-stable: in direct sun it ambers, chalks and loses gloss, sometimes within a single season. Outdoor slabs are also rarely poured over a vapour barrier and sit on wet ground, so moisture drives up from below, while freeze-thaw cycles and rain attack the bond from above. The usual result is peeling and blistering within a year or two.
For outdoor concrete, the better-value options are a penetrating stain or a breathable sealer, which have nothing to peel, or an aliphatic polyaspartic system designed for UV exposure if you want a coated look. The trade-offs between paint, sealer and epoxy on different slabs are laid out in concrete floor paint vs epoxy.
Commercial and Industrial
Commercial floors are specified by thickness and service conditions rather than looks, and the range is correspondingly wide. A thin-film roll-coat in a dry storage room may be priced not far above a residential system, while a 1/16"–1/8" broadcast quartz system, a troweled epoxy mortar, or a urethane-cement floor for a commercial kitchen or food plant commonly runs from several dollars to $12 or more per square foot installed. The spread comes from film build, the preparation method (shot blasting is standard), integral cove base, chemical and thermal-shock requirements, and whether the work has to happen on nights and weekends to avoid shutting the business. The commercial epoxy flooring guide covers system selection for those settings.
Cost by Floor Area
Total cost scales with area, but not linearly. Mobilisation, equipment, a minimum crew day and the fixed cost of repairs and edge work are spread over fewer feet on a small job, so small floors cost noticeably more per square foot.
| Area | DIY kit | DIY high-solids + topcoat | Pro epoxy + flake + topcoat | Pro full polyaspartic |
|---|---|---|---|---|
| 100 sq ft | $75 – $150 | $200 – $450 | $800 – $1,500 | $1,000 – $1,800 |
| 250 sq ft | $100 – $250 | $350 – $800 | $900 – $2,200 | $1,400 – $2,800 |
| 500 sq ft | $150 – $400 | $600 – $1,400 | $1,500 – $3,500 | $2,500 – $5,000 |
| 750 sq ft | $250 – $600 | $900 – $2,100 | $2,300 – $5,200 | $3,700 – $7,300 |
| 1,000 sq ft | $300 – $800 | $1,200 – $2,800 | $3,000 – $7,000 | $5,000 – $9,500 |
| 1,500 sq ft | $450 – $1,200 | $1,700 – $4,000 | $4,500 – $9,500 | $7,500 – $14,000 |
| 2,000 sq ft | $600 – $1,600 | $2,200 – $5,200 | $6,000 – $12,500 | $10,000 – $18,500 |
Look at the 100-square-foot row: $800–$1,500 professionally works out to $8–$15 per square foot for a system that costs $3–$7 on a two-car garage. That is the minimum charge at work. Most residential coating contractors will not load a truck for less than roughly $800–$1,500, because the travel, setup, grinding, cleanup and return trip for the topcoat cost them the same on a mudroom as on a garage. If you have a small area, the cheapest professional route is often to bundle it — do the laundry room at the same time as the garage, and the extra floor is priced at the margin rather than as a separate job.
At the other end, per-foot prices flatten above about 1,000 square feet as setup is amortised, but they do not keep falling forever. Material is a real share of the cost on large floors, and a 2,000-square-foot space usually needs more crew or more days.
What Drives the Price
1. Surface Preparation
The single largest labour item and the most common place to cut corners. Diamond grinding opens the concrete surface to a profile the coating can grip and removes sealers, laitance and contamination. Shot blasting does the same faster on large areas. Acid etching is cheap and quick, but it does nothing to remove sealers or embedded oil and is far less reliable. A quote that grinds and a quote that etches are different jobs, and the price difference between them is largely the grinding. Removing an existing failed coating adds roughly $1–$3 per square foot on top. The trade-offs are covered in more depth in our guide to how to apply garage floor epoxy, which starts with preparation for exactly this reason.
2. Moisture
Moisture vapour moving up through a slab is the leading cause of epoxy delamination, and fixing it is expensive. A moisture-mitigating primer or topical vapour barrier adds $1–$3 per square foot. It is most common on basements, slabs on grade without a barrier, and older homes. A contractor who does not test cannot know whether you need it, which means they are either pricing it in blind or leaving you exposed.
3. Cracks, Spalls and Joints
Hairline cracks are usually filled as part of preparation. Wider cracks, spalled areas, pitted surfaces and control joints are often priced separately, commonly by the linear foot, and a heavily damaged slab may need a skim coat or self-levelling resurfacer before coating. On a DIY job, crack and spall repair runs $30–$150 in materials on a typical floor. Note that coatings do not stop cracks that are still moving; a crack that reopens will telegraph through any coating.
4. Film Thickness and Solids Content
Epoxy is sold from roughly 40% to 100% solids. Solids are what remain after the solvent or water evaporates, so a 50% solids product applied at 10 mils wet leaves about 5 mils of film, while a 100% solids product leaves all 10. Thicker film lasts longer and bridges minor surface flaws, but it needs more material per square foot. This is the main reason two quotes for "epoxy with flake" can be $2 a foot apart: one builds 15–20 mils total, the other 6–8. Ask for finished thickness in mils.
5. Flake, Quartz and Metallic Finishes
A full flake broadcast adds about $0.50–$1.50 per square foot and is the most cost-effective decorative upgrade. Partial or light broadcasts cost less but hide less. Quartz broadcast, used for heavy-traffic and commercial floors, costs more and adds texture. Metallic epoxy is the expensive end — $8–$15 installed — because the material is pricier and the application is hand-worked art that some crews simply do not offer.
6. Topcoat Chemistry
A polyaspartic or polyurethane clear coat over the epoxy adds roughly $1–$3 per square foot and protects the base from abrasion, UV yellowing and hot-tire pickup. Bare epoxy dulls and scratches noticeably faster. If a quote leaves the topcoat out to hit a price, the saving tends to be paid back with a recoat years earlier.
7. Cove Base and Edge Detail
Integral cove base — the coating turned up the wall in a curve — is standard in commercial kitchens and wash-down areas and occasional in high-end garages. It is priced by the linear foot, commonly somewhere in the $8–$25 range depending on height and substrate, and it can add meaningfully to a small room with a lot of perimeter. Stem walls, steps and garage aprons are also often priced as extras.
8. Access, Logistics and Timing
Stairs, tight doorways, distance from the truck, lack of suitable power for large grinders, furniture or stored items to move, and after-hours scheduling all add labour. So does climate: epoxy needs the slab and air within a temperature window to cure properly, so unheated garages in cold months may need heaters or a delayed start. Spring is peak season for garage coatings in most of the US, and schedules — and prices — tighten accordingly.
9. Minimum Charges
As the area table shows, small jobs cost more per foot. Expect most installers to quote a floor price of roughly $800–$1,500 regardless of size, and some won't take very small rooms at all.
Estimate Your Own Floor
You can build a materials estimate from three numbers: the area, the target dry film thickness, and the solids content on the product's technical data sheet. The key fact is that one US gallon spread over 1,604 square feet makes a film exactly 1 mil (0.001 inch) thick. Everything else follows from that.
Theoretical coverage (sq ft per gallon) = 1,604 × solids fraction ÷ dry mils
| Dry film per coat | 100% solids | 70% solids | 50% solids |
|---|---|---|---|
| 3 mils | ~535 sq ft/gal | ~375 sq ft/gal | ~265 sq ft/gal |
| 5 mils | ~320 sq ft/gal | ~225 sq ft/gal | ~160 sq ft/gal |
| 8 mils | ~200 sq ft/gal | ~140 sq ft/gal | ~100 sq ft/gal |
| 10 mils | ~160 sq ft/gal | ~110 sq ft/gal | ~80 sq ft/gal |
| 15 mils | ~105 sq ft/gal | ~75 sq ft/gal | ~55 sq ft/gal |
| 20 mils | ~80 sq ft/gal | ~55 sq ft/gal | ~40 sq ft/gal |
Real-world coverage is lower than theoretical. Porous or freshly ground concrete absorbs part of the first coat, rollers and buckets hold product, and edges always use more than the middle. Allow 10–15% extra, and more on a rough or very thirsty slab. The table also explains why coverage claims on retail kits are revealing: a kit that says it covers 500 square feet per gallon is laying down roughly 3 mils of a 100% solids product, or much less of a water-based one.
Worksheet: a 500 sq ft Floor
| Line | How to work it out | Example |
|---|---|---|
| 1. Area | Length × width of each section, added up | 20 ft × 25 ft = 500 sq ft |
| 2. Base coat coverage | 1,604 × solids ÷ target dry mils | 100% solids at 10 mils ≈ 160 sq ft/gal |
| 3. Base coat gallons | Area ÷ coverage, + 10–15% | 500 ÷ 160 = 3.1 → ~3.6 gal; buy 4 |
| 4. Primer (if required) | Per data sheet; thin coats cover more | Often 1–2 gal on 500 sq ft |
| 5. Flake | Full broadcast uses roughly 1 lb per 8–12 sq ft | ~45–60 lb |
| 6. Topcoat gallons | Same formula; over full flake allow more | Often 2–3 gal polyaspartic on 500 sq ft |
| 7. Prep and repair | Grinder rental, diamonds, vacuum, degreaser, crack filler | $150–$400 |
| 8. Sanity check | Total ÷ area | Should land near $1.75–$3.00/sq ft for a high-solids system |
Price lines 3–6 from the supplier you intend to use, then add line 7. For a 500-square-foot garage, a high-solids base with flake and a polyaspartic topcoat usually totals $600–$1,400 all in, consistent with the table above. If your number comes out far below $1 per square foot, check whether you have used the optimistic coverage figure from the box rather than the one implied by solids and mils. If it comes out far above $3.50, check whether you are pricing a premium system or have double-counted coats.
If you are comparing specific products, solids content and recommended thickness are the two specs that matter most; the best garage floor epoxy roundup lists them for the major kits.
Quote Red Flags
- A price with no preparation method. If the quote does not say "diamond grind" or "shot blast", assume it is acid etch or a quick scuff, and price the comparison accordingly.
- No moisture test. Especially on basements and older slabs. Testing costs very little; skipping it can cost the whole floor.
- No thickness or solids content. "Commercial-grade epoxy" is not a specification. A reputable installer names the products and can tell you the mils.
- A full flake system well under $3 per square foot. Not impossible on a large, clean slab, but at that price something — grinding, film build, flake density or the topcoat — is usually missing.
- "One-day floor" with an ordinary epoxy base. Same-day and next-day return to service is a legitimate feature of polyaspartic and polyurea systems. Standard epoxy typically needs several days before vehicles, so a claim that it is ready the next day deserves a question.
- A lifetime warranty with no written exclusions. Read what it covers. Many exclude moisture-related failure, hot-tire pickup or chemical damage — the main ways floors fail.
- Crack repair "included" with no detail. Ask how cracks and joints will be treated and whether wide cracks are extra.
- A large deposit far ahead of the work. A modest deposit for materials is normal; most of the payment should follow completion.
Ways to Save
Do it yourself — properly. A DIY high-solids epoxy with a polyaspartic topcoat on a ground floor costs roughly a third to a half of the professional price and closes most of the performance gap. The cheapest big-box kit saves more up front but often needs redoing within a few years. Polyaspartic base coats, with pot lives measured in minutes, are best left to pros.
Bundle small areas. Adding a laundry room or mudroom to a garage job avoids a second minimum charge. Neighbours booking the same installer on adjacent days sometimes get a better rate too.
Match the system to the room. A basement storage room does not need metallic, and a garage does not need a 1/8" industrial mortar. Solid colour plus topcoat costs less than full flake; partial flake costs less than full.
Keep the topcoat, cut the extras. If something has to go, drop decorative upgrades or cove base before you drop the topcoat or the grinding.
Fix moisture and drainage first. Grading, gutters and a working dehumidifier can lower slab moisture readings before the coating goes down, which may reduce or remove the need for a mitigation primer.
Get three quotes on the same specification. Give every installer the same scope — preparation method, product type, thickness, flake coverage and topcoat — so the totals are actually comparable.
Book outside peak season. In most regions, late fall and winter are slower for garage coatings. Heated spaces such as basements can be done any time, and some installers price quiet months more keenly.
The Short Version
For most homes, budget $3–$7 per square foot for a professionally installed epoxy floor with flake and a polyaspartic topcoat, or $1.75–$3.00 in materials to do a high-solids system yourself. Add $1–$3 per square foot where the slab needs moisture mitigation, which is common in basements, and expect $8–$15 for a metallic finish in a living space.
Small floors cost more per foot because of minimum charges, so bundle them where you can. Keep epoxy off patios and sunlit outdoor slabs. And before comparing totals, compare the specification: preparation method, solids content, finished thickness and topcoat. Those four lines explain almost every difference between a cheap quote and a good one.
Frequently Asked Questions
Professionally installed, $3–$5 per square foot for mid-grade epoxy, $4–$7 for high-solids or 100% solids epoxy, $3–$7 for an epoxy base with full flake and a polyaspartic topcoat, $5–$10 for a full polyaspartic or polyurea system and $8–$15 for metallic epoxy. DIY materials run $0.30–$0.80 for a big-box water-based kit and $1.75–$3.00 for a high-solids system with topcoat. Moisture mitigation adds $1–$3 per square foot where needed, and small rooms cost more per foot because of installer minimums.
A typical 500-square-foot two-car garage costs $150–$400 with a DIY big-box kit, $600–$1,400 with a DIY high-solids epoxy and polyaspartic topcoat, $1,500–$3,500 for a professional epoxy-flake-topcoat system and $2,500–$5,000 for professional full polyaspartic. The spread comes mostly from film thickness and surface preparation. Our epoxy garage floor cost guide breaks this down by garage size and gives a full job timeline.
Because most of a professional job's cost is fixed. Travel, setup, grinding equipment, edge work, cleanup and a second visit for the topcoat cost an installer roughly the same on a 100-square-foot mudroom as on a 500-square-foot garage. Most contractors set a minimum charge of roughly $800–$1,500, which works out to $8–$15 per square foot on a small room. Adding the small space to a larger job is usually the cheapest way to get it done professionally.
A flake epoxy system at $3–$7 per square foot installed is generally comparable to or cheaper than installed porcelain tile or hardwood, and cheaper still if you do it yourself. Metallic epoxy at $8–$15 is in the same range as mid-to-premium tile. The catch for living spaces is that epoxy requires a concrete slab: if you have to remove existing tile and grind adhesive first, the saving narrows, and epoxy is harder and colder underfoot than most alternatives.
Usually, by roughly $1–$3 per square foot. Below-grade slabs are far more likely to have moisture vapour coming through them, and a moisture-mitigating primer or vapour barrier system is often needed to keep the coating bonded. Access down stairs and working around mechanical equipment also add labour. A typical 800-square-foot basement lands at around $3,000–$7,500 professionally, depending on moisture readings and finish.
It is not recommended. Standard epoxy is not UV-stable and yellows, chalks and loses gloss in direct sunlight, and outdoor slabs typically have moisture moving up from the ground and freeze-thaw cycles working on the bond. Peeling and blistering are common within a year or two. A penetrating stain or breathable sealer, or a UV-stable aliphatic polyaspartic system, is the better choice outdoors.
It depends on solids content and film thickness. One gallon spread over 1,604 square feet gives 1 mil of film, so a 100% solids epoxy covers about 160 square feet per gallon at 10 mils, while a 50% solids product covers only about 80 square feet per gallon at the same dry thickness. Real-world coverage is 10–15% lower than theoretical because porous concrete absorbs part of the first coat. Retail kits claiming 400–500 square feet per gallon are laying down a very thin film.
It varies widely with the system. A thin roll-coat in a dry storage area may cost not much more than a residential floor, while 1/16"–1/8" broadcast quartz, troweled epoxy mortar and urethane-cement systems for kitchens, food plants and warehouses commonly run from several dollars to $12 or more per square foot installed. Thickness, shot-blast preparation, integral cove base, chemical and thermal requirements, and after-hours scheduling to avoid downtime are what move the price.
