Floor Coating Cost Calculator
Set your square footage, choose a coating chemistry, and tell it the truth about your slab. You get the same national average range a good contractor works from, before anyone knocks on your door.
National average cost by material
Installed pricing, professionally applied over a diamond ground slab in sound condition. Prep for cracks, oil, or moisture rides on top of these numbers.
| Coating system | Cost per sq ft | Two-car garage (480 sq ft) | Expected life |
|---|---|---|---|
| DIY big-box epoxy kit | $1.00 to $2.50 | $480 to $1,200 | 1 to 3 years |
| Professional solid-color epoxy | $4.00 to $7.00 | $1,920 to $3,360 | 5 to 10 years |
| Epoxy base with polyaspartic topcoat | $6.00 to $10.00 | $2,880 to $4,800 | 12 to 18 years |
| Full polyaspartic flake system | $7.00 to $12.00 | $3,360 to $5,760 | 15 to 20 years |
| Quartz broadcast system | $8.00 to $15.00 | $3,840 to $7,200 | 15 to 20 years |
| Metallic epoxy | $8.00 to $18.00 | $3,840 to $8,640 | 10 to 15 years |
| Urethane cement | $9.00 to $20.00 | $4,320 to $9,600 | 15 to 25 years |
How to read the number
The low end of every range assumes an easy job: a clean, dry, single-level slab, a clear work area, and a crew that can pull up and start grinding. The high end assumes the opposite. Two identical garages on the same street can quote four dollars apart on square footage alone.
Price per year of service is the honest comparison. A two hundred dollar big-box kit that peels in eighteen months costs more per year than a polyaspartic flake system that holds for two decades, and the second one does not need to be ground off before the next floor goes down.
If a quote lands under these ranges, ask what was removed. Usually it is grinding, replaced by acid etching, or a moisture test nobody ran. Both are cheap to skip and expensive to fix.

Calculator questions
- How accurate is this floor coating cost calculator?
- It uses national average installed pricing per system over a diamond ground slab in sound condition. Expect a real quote to land inside the range, with slab repair, moisture mitigation, and access difficulty pushing toward the high end.
- What square footage should I enter for a two-car garage?
- Most two-car garages measure 400 to 500 square feet. Three-car garages run about 620 to 750. Measure wall to wall and skip the deductions, since crews grind the full slab.
- Why does slab condition change the estimate so much?
- Cracks, spalling, oil saturation, and vapor drive all add labor before any coating goes down. Repair and vapor barrier primer commonly add $0.75 to $2.50 per square foot.
- Which system gives the best cost per year?
- Polyaspartic flake usually wins. It costs more up front than epoxy but delivers 15 to 20 years of service, which brings the annual cost below systems that need replacing twice in the same window.
- Does the estimate include removing an old failed coating?
- No. Grinding off a delaminating epoxy floor is extra labor and disposal, typically $1 to $3 per square foot on top of the new system.
