How to measure and price epoxy floor work
- Price per square foot by system: single-coat solid color, full flake, or metallic — they are three different labor curves.
- Add crack/spall repair as an allowance with a per-linear-foot overage rate.
- Quote moisture mitigation as a conditional line so a failed test does not eat your margin.
Epoxy Floor building-code guide
Epoxy failures are prep failures. Every callback traces back to profile, moisture or recoat window, so quote the prep honestly.
- Mechanically grind to a CSP 2–3 profile; acid etching is not an acceptable substitute for a warranted system
- Repair cracks and spalls with a rigid polyurea or epoxy patch, not caulk
- Vacuum with a HEPA extractor and tack the floor immediately before priming
- Run a calcium chloride (ASTM F1869) or in-situ RH (ASTM F2170) test on slabs on grade before quoting a warranty
- Above roughly 4 lbs/1,000 sq ft/24 hr or 80% RH, a moisture-mitigating primer is required
- Slabs less than 28 days old are not ready for most coating systems
- Respect the recoat window between coats — miss it and the next coat needs an abrasion pass
- Keep slab temperature above the product minimum and at least 5°F above the dew point
- Typical service: foot traffic in 24 hours, vehicles in 72 hours for polyaspartic topcoats

Adjust the values — the drawing below updates in real time.
- 1 · Polyaspartic topcoat — vehicles after 72 hrs(0.06")
- 2 · Flake broadcast — full refusal, then scraped(0.50")
- 3 · Pigmented base coat — respect recoat window(0.06")
- 4 · Primer over ground slab — moisture primer if RH > 80%(0.06")
- Polyaspartic topcoat: 0.06"
- Flake broadcast: 0.50"
- Pigmented base coat: 0.06"
- Primer over ground slab: 0.06"
- Total assembly: 0.69" (0 11/16")

Common epoxy floor estimating mistakes
- Skipping the moisture test on a slab on grade, then losing the entire floor to delamination.
- Not charging for garage clearing and appliance moving on jobs full of shelving.
- Promising same-day vehicle return; tires lift uncured coatings.

Epoxy Floor estimate FAQ
How much does an epoxy garage floor cost?
A two-car flake floor typically runs $4,000–$7,000 installed, depending on prep condition, system type (flake vs. metallic) and whether moisture mitigation is required.
What should an epoxy floor estimate include?
It should list grinding and prep, crack and joint repair, moisture testing, primer, base coat, flake or metallic media, topcoat, labor days, and the cure schedule before foot and vehicle traffic.
How long does an epoxy garage floor take?
Most residential installs are two days: prep and base on day one, flake scrape and topcoat on day two. Foot traffic is usually safe after 24 hours and vehicles after 72 hours.
