Polished vs epoxy cost of ownership over 10 years isn’t close in our Oklahoma numbers. A polished floor totals about $6.26 a square foot, counting one densifier pass around year 5. An epoxy floor totals about $13.23 with one recoat, or about $17.64 with two. The install prices come from our past quotes. The recoat timing comes from coating makers, and we show every input so you can swap in your own.
How was this math built?
Two kinds of numbers go into it, and they come from two different places.
The price side comes from our quotes. We pulled our own Oklahoma quotes, dated 2021 to 2026. The full set holds 245 quotes across five kinds of floors. Of those, 94 were polished concrete and 82 were epoxy. We strip out names, addresses, phone numbers, and job stories, and we only publish state and metro numbers. Each price on this page shows its n, the number of quotes behind it. The full method is in our public methodology document. For price by job size, see the polished concrete cost study and the epoxy floor cost study.
The lifespan side comes from outside sources. We didn’t use our own records for how long a floor lasts or how often it needs a recoat. Those numbers come from these sources, and we name the source each time we use one:
- Penntek manufacturer guidance: how often epoxy and polyaspartic floors need a recoat.
- Prosoco LS Guard specification and Ameripolish product literature: how a densifier hardens polished concrete, and how long it holds up.
- Husqvarna HiPERFLOOR reference material: the upkeep a polished floor needs.
- The ICRI 310 series: the standards for getting a slab surface ready.
- ASTM C1315: the spec for curing and sealing compounds on new concrete. It sits on our source list, but it doesn’t set how long a coating lasts, so we don’t use it for that.
So this page is not a study of how often floors fail. It makes no claim, good or bad, about how any floor we installed has held up.
What does each floor cost to install?
Here are the medians (the middle price) from our Oklahoma quotes:
- Polished concrete: The middle half of those jobs ran $4.80 to $6.67 a square foot.
- Epoxy and resinous coatings: The middle half ran $6.55 to $14.20 a square foot.
In the OKC metro the medians ran a little higher: $5.79 for polished (59 quotes) and $9.67 for epoxy (63 quotes). More of the OKC epoxy jobs were high-end home garages with fancier coatings, and that pushes the middle price up.
At the state median, epoxy costs about 55% more to install than polished. That’s half the story. The other half is what each floor costs to keep up.
Those medians are history, not a quote. Your number today comes from our quote tool. Slab Boss Polish, our polished concrete system, runs $3.83 to $6.25 a square foot, from the base polish up to every upgrade. RESA Flake, our flake garage floor (color flake in epoxy under a clear topcoat), runs $8.55 to $10.39. RESA Quartz and RESA Metallic epoxy floors run $6.08 to $10.17. The recoat pattern in this study still holds at those prices. Polished skips the recoat cycle. Epoxy still needs one. Those spans count setup but not the drive cost, which is our trip to your site. Put your floor size and address in the quote tool and it adds the drive for you.
How long does each floor last?
Polished concrete. Per Husqvarna HiPERFLOOR reference material, a properly densified polished floor is a permanent floor with no recoat cycle under normal care. The slab itself is the floor. The densifier (lithium silicate, per Prosoco LS Guard and Ameripolish product literature) reacts with calcium hydroxide in the concrete. That forms a hard, tight surface that soaks up very little. Those same references call a fresh densifier pass on busy paths upkeep, not a recoat. So the floor lasts as long as the slab does.
Epoxy and resinous coatings. Per Penntek manufacturer guidance, home and light commercial epoxy and polyaspartic floors need a recoat every 5 to 7 years in normal garage use. Heavy commercial traffic shortens that. Light home use stretches it. We use 5 to 7 years here because that’s the typical figure for a home garage or a light commercial floor.
That’s the whole reason the two 10-year totals split apart. One floor is the slab. The other is a film on top of the slab, and films wear.
What is the recoat factor for epoxy?
The recoat factor is what a recoat costs as a share of the first install price. Coating makers commonly put it at about half. The slab was already ground and primed the first time. A recoat only needs a machine scuff of the old surface, primer touch-ups, and a fresh topcoat.
The 50% doesn’t come from one spec sheet. It’s the usual way makers like Penntek and Ameripolish talk about a topcoat refresh in their product literature and installer training. It also lines up with what coating installers in our market charge for a refresh job.
You can swap in your own factor. At 40%, the one-recoat epoxy total drops to about $12.35 a square foot. At 60%, it climbs to about $14.11. The polished densifier pass (about 10% of the install price, once, around year 5) is also a typical figure, not one from a single spec. Skip that pass and the polished 10-year total is just the $5.69 install price.
The 10-year cost of ownership math
The 10-year total is the install price, plus the number of recoats times the recoat factor times the install price. At the Oklahoma median, each floor works out like this.
Polished concrete, 10 years:
- Install price: $5.69 a square foot (94 quotes)
- Recoats: none under normal care, per Husqvarna HiPERFLOOR and Prosoco LS Guard documentation
- One densifier pass around year 5: about $0.57 a square foot (about 10% of the install price)
- 10-year total: about $6.26 a square foot
Epoxy, 10 years, one recoat (the low end):
- Install price: $8.82 a square foot (82 quotes)
- Recoats: 1, in year 5 to 7, per Penntek recoat guidance
- Recoat price: about $4.41 a square foot (half the install price)
- 10-year total: about $13.23 a square foot
Epoxy, 10 years, two recoats (the high end):
- Install price: $8.82 a square foot (82 quotes)
- Recoats: 2, which is common on busy home or light commercial floors, per the same manufacturer guidance
- Recoat price: about $4.41 each, or $8.82 for both
- 10-year total: about $17.64 a square foot
On a 1,000 square foot floor at the Oklahoma median, that works out to:
- Polished concrete: about $6,260 over 10 years
- Epoxy with one recoat: about $13,230 over 10 years
- Epoxy with two recoats: about $17,640 over 10 years
Against one epoxy recoat, polished comes out about 2.1 times cheaper. Against two, the gap grows to about 2.8 times.
What can change the answer?
The math rests on the sources above. These things can push it one way or the other.
Slab condition. A cracked, spalled, or badly worn slab may need repair or an overlay before either floor goes down, per ICRI 310 surface prep guidance. That cost lands on both totals about equally, so the gap between them barely moves. If your slab has open cracks, flaking, or an old coating that failed, expect a higher install price either way.
Traffic. Per manufacturer recoat guidance, heavy commercial or industrial use shortens epoxy recoats to every 3 to 5 years instead of 5 to 7. On polished concrete, it means a densifier pass every 3 to 5 years instead of once a decade. For a garage or a home, the math above holds. For a busy commercial or industrial floor, both totals go up and the gap shrinks some.
Weather. Garage slabs near an outside door get freeze-thaw cycles and de-icing salt. Per Husqvarna HiPERFLOOR material, polished concrete handles those spots better than a coating, since there’s no film stuck to the slab to lift. So a coating by the door may need a recoat sooner. Weather moves the numbers less than slab condition or traffic does, but it shows up over a decade.
Upkeep. Every maker we cite says skipped upkeep wears either floor faster. Our math assumes normal care: regular cleaning, a densifier pass on polished now and then, and recoats on the schedule the coating maker sets. If you know you won’t keep up with either floor, expect both totals to land higher than ours.
Your recoat factor. Some installers charge 35 to 40% of the install price for a recoat on smaller floors. Others charge 60 to 70% on badly worn floors that need extra prep. If your contractor quotes a different share, put it in place of our 50% and run the math again.
Which floor should you pick?
This page doesn’t crown one floor for every job. Both have good uses, and the 10-year price is one input, not the only one.
- Pick polished concrete if the slab you have is the floor you want, and you want a finished, low-upkeep surface that lasts decades.
- Pick an epoxy or polyaspartic coating if you want a separate floor on top of the slab, for chemical resistance, a decorative chip broadcast, or a specific industrial need.
For the other things that drive this choice (slab moisture, how hard the floor gets used, surface prep, slip resistance, and looks), see the polished concrete vs concrete coatings decision guide.

Limits of this page
It has no national prices, because our data is Oklahoma only. It has no breakdown of our own costs of any kind. And it stops at 10 years. The makers’ recoat timing supports a decade of math, and past that, small errors in the inputs stack up.
When this page refreshes
We update this page at least once a year. We update it sooner if any price or recoat source we cite moves more than 15% from what we published. Each update goes out at a new dated address, and the old version stays up at its own dated address. The next planned update is May 2027.
