Epoxy flooring cost in Coeur d'Alene, Idaho
Real Kootenai County ranges by system and by garage size, plus the three lines that make a North Idaho estimate different from one in a mild town: the moisture reading, the freeze-thaw repairs, and which system can cure in the month you want the floor.
The short answer
How much does epoxy flooring cost in Coeur d'Alene?
A professional garage floor coating in Coeur d'Alene runs $7 - $10 per square foot for a full-flake system over diamond-ground, moisture-tested concrete, top coat included. That puts a two-car garage at $2,900 - $4,300 and a three-car garage at $4,600 - $6,800. Solid-color epoxy comes in at $5 - $7.50 per square foot, a one-day polyaspartic floor at $9 - $13, and a metallic designer floor at $11 - $16.
Those numbers sit a little above what the same floor costs in the Midwest, for three reasons that do not go away: freight into North Idaho, a coating season that is shorter than most of the country's, and crews that are busy every warm week of it. What they buy is a floor that survives studded tires and mag chloride, which a cheaper floor here does not.
- Moisture mitigation on a new or damp slab: $1.50 - $3 per sq ft
- Crack and spall repair after a hard winter: $150 - $600 on most garages
- Recoat of a sound existing floor: $3 - $5 per sq ft

Inside the range
What moves the price on a Coeur d'Alene floor?
Six things decide where a floor lands inside its range. Three of them, the moisture, the winter, and the month, are the reason a Kootenai County estimate reads differently from one written for a garage that never sees a stud or a frost.
The moisture reading
A slab poured in the last few years on the Prairie is often still giving up water. If the meter says so, a mitigation primer goes down first, $1.50 - $3 per sq ft. Skip it and the floor bubbles by the second summer. A dry, seasoned slab skips the line entirely.
What last winter did
The spot by the door where snowmelt and de-icer sat all winter is usually pitted, and there is often a crack running from the drain. Cutting, filling and patching is $150 - $600 on most garages, priced before the coating goes down, never discovered after.
The month
Not a surcharge, a system choice. Epoxy needs concrete in the fifties to cure; from November into March a Coeur d'Alene slab is not there. A cold-season floor is quoted as polyaspartic, which costs more per foot and cures in the cold, or it waits for spring at the epoxy price.
The size
The grinder and the crew cost the same to bring out for a small floor as a big one, so per-foot rates fall as square footage rises. A three-car garage is a better rate than a two-car; a 12x12 room on its own hits the $1,200 minimum.
The system
Solid color is the base price, flake adds the broadcast and scrape, polyaspartic adds a faster and dearer material, metallic adds a hand-worked pour. Same prep under all of them, which is why the cheap number on a bid should make you ask what was skipped.
What is already on it
A previous coating that is stuck gets scuffed and recoated at $3 - $5 per sq ft. One that is lifting has to be ground off before anything new can bond, and that grinding is real time. The garage page explains how to tell which one you have with a putty knife.
The questions people actually type
How much does a 20x20 epoxy floor cost?
A 20x20 garage is 400 square feet, and in Coeur d'Alene a full-flake system on it runs $2,800 - $4,000 installed. That is the $7 - $10 per-square-foot range with the grind, the primer, the base, the flake and the top coat all inside the number. A one-day polyaspartic system on the same 400 feet prices at $9 - $13 per square foot. If the meter finds moisture or the door apron needs patching, those show up as their own lines.
How much does it cost to epoxy 1000 sq ft?
Around $7,000 - $11,000 for a full professional system. A thousand square feet is a big residential shop or a small commercial bay, and floors that size earn a better per-foot rate than a garage because the setup spreads out. Once the spec turns commercial, with slip texture, striping, or a urethane-cement zone under a forklift lane, the number is built from the spec at $5 - $12 by spec per square foot instead of from the table.
How much does it cost to epoxy a 2 car garage?
$2,900 - $4,300 for full flake, which is most of the two-car garages in Kootenai County at 400 to 450 square feet. Solid color trims that at $5 - $7.50 per foot; polyaspartic raises it at $9 - $13. A three-car garage, usually 650 to 700 square feet here, runs $4,600 - $6,800. Every one of those includes the top coat, because a garage floor without one is not a garage floor in this climate.
How much does a 12x12 epoxy floor cost?
More per foot than anything else on this page. A 12x12 room is 144 square feet, and the grinder, the dust extraction and the crew cost the same to bring out whether the floor is 144 feet or 600. Expect $1,300 - $1,900, because a minimum job of $1,200 applies to any floor on its own. The honest workaround is to coat the small room the same day as the garage, where it rides along at the per-foot rate.
Is epoxy cheaper than concrete? Cheaper than tile?
Cheaper than tile in a garage, and tile does not take studded tires anyway. Against new concrete, a coating is a fraction of the cost of tearing out and re-pouring, with one condition: the slab has to be sound. A coating fixes a slab's surface, not its structure. If the concrete is heaving from frost or crumbling into aggregate, the measure will say concrete first, and no honest crew will coat over it.
What is the downside of an epoxy garage floor?
In Coeur d'Alene, three: it cannot cure on a cold slab, so it is not a winter install; it bubbles over a damp slab nobody metered; and a thin kit coat peels under studs by the second winter. Every one of those is a prep or system-choice failure rather than a flaw in the coating itself, and every one is avoidable on paper before the job starts. The full list, including the floors that should not be coated at all, is in the downsides guide.
The range is on this page. The number is one measure away.
Square footage, the year the slab was poured, and the month you want it done. That places the floor in a range by system before anyone comes out.
Reading the paper
What a floor coating estimate should show
An estimate worth accepting is itemized, names the system, and is written down before anyone starts a grinder. Five lines cover nearly every floor in this county.
- The prep. How the slab is profiled (diamond grinding, not acid) and the moisture reading that was taken.
- Repairs. Cracks, spalls and the door apron, $150 - $600 on most garages, listed so the number cannot grow on the day.
- Moisture mitigation. Its own line when the meter calls for it, $1.50 - $3 per sq ft, and absent when it does not.
- The system. Base, broadcast and top coat by name, with the month it is being installed and why that system can cure in it.
- The cure window. When you walk on it and when you park on it, in writing.
Compare any bid, including one from somebody else, against the table above. A number far above it deserves a question. A number far below it deserves a harder one, usually about which of the five lines is missing.
Sign today, zero down
Coatings are sold hard in this valley: same-day signing, nothing down, a price that is only good until the truck leaves. Some of those floors are fine. Enough are not that the rule is worth keeping: no grinder starts until there is a written, itemized number, and a price that cannot survive being taken home overnight was never the real price. The pros this site connects you with put the estimate on paper and let you compare it.
The system is half the number. Here is what the cold-season one buys.
Asked around Kootenai County
Price questions, answered with numbers
How much does a 20x20 epoxy floor cost?
A 20x20 garage is 400 square feet. In Coeur d'Alene a professional full-flake system over diamond-ground, moisture-tested concrete lands between $2,800 - $4,000, which is $7 - $10 per square foot with the top coat included. A one-day polyaspartic system on the same floor runs $9 - $13 per square foot. Repairs and moisture mitigation are separate lines on the written estimate.
How much does it cost to epoxy 1000 sq ft?
Plan on $7,000 - $11,000 for a full professional system at 1,000 square feet in Kootenai County. Larger floors earn a better per-foot rate than small ones because the grinder setup and mobilization spread out across more concrete. Shop floors with striping or a urethane-cement zone price by spec, $5 - $12 by spec per square foot.
How much does it cost to epoxy a 2 car garage?
A two-car garage here, roughly 400 to 450 square feet, runs $2,900 - $4,300 for a full-flake system with prep and the top coat included. A three-car garage runs $4,600 - $6,800. Solid-color epoxy comes in lower at $5 - $7.50 per square foot; a one-day polyaspartic floor comes in higher at $9 - $13.
How much does a 12x12 epoxy floor cost?
A 12x12 room is 144 square feet, and at that size the per-foot math stops working: the grinder, the dust extraction and the crew cost the same to bring out for a small floor as for a garage. Expect $1,300 - $1,900 for a small floor, because a minimum job of $1,200 applies. A small floor coated alongside the garage on the same day avoids the minimum.
Is epoxy cheaper than tile or new concrete?
Against tile, yes. A full-flake coating at $7 - $10 per square foot installed sits well under tile in a garage, and tile does not take studded tires. Against tearing out and re-pouring a slab, a coating is a fraction of the cost, but only if the slab is sound. A heaving or crumbling slab is a concrete problem first, and the measure will say so.
What is the downside of an epoxy garage floor?
Three honest ones in Coeur d'Alene: epoxy cannot cure on a cold slab, so it is not a November-to-March install; it will bubble over a damp slab that was never metered; and a thin kit coat peels under studded tires by the second winter. All three are prep and system-choice problems, not coating problems. The full list, including when not to coat at all, is in the downsides guide.
Written estimates, by system
Want the number for your floor instead of a range?
Square footage, the year the slab was poured, and whether it has ever been coated. That is enough to place it in the table, and the measure turns the range into a written number by system. Prefer the phone? Call (208) 758-9728.
