Garage Floor Coating Cost Calculator
Budget a garage floor coating from bay area and system type—epoxy flake, polyaspartic, or metallic—plus grinding, moisture mitigation, and hotspot repairs.

How to use this calculator
- Enter the garage floor square footage.
- Choose epoxy flake, polyaspartic, or metallic pricing.
- Toggle diamond grind, moisture mitigation, and hotspot repair.
- Select your state and review prep vs coating lines.
Results explained
System rate × area is the coating base. Diamond grind and moisture mitigation add per-square-foot prep; hotspot repair is flat.
Quick reference: garage coating midpoints
Installed U.S.-average midpoints before the selected state adjustment.
| Scope | Midpoint |
|---|---|
| Epoxy flake | $6.00/sq ft |
| Polyaspartic (default) | $9.50/sq ft |
| Metallic epoxy | $12.00/sq ft |
| Diamond grind | +$1.50/sq ft |
| Moisture mitigation | +$2.25/sq ft |
| Hotspot repair | $350 flat |
Rates are planning midpoints; difficult access, repairs, and minimum job charges can shift quotes.
How the estimate is built
Total ≈ (sq ft × system $/sq ft) + Σ(prep $/sq ft × sq ft) + hotspot flat, then × state multiplier.
Example scenario
A 400 sq ft polyaspartic floor with diamond grind is about $4,400 at U.S. average ($9.50 × 400 + $1.50 × 400).
FAQ
Do I need a diamond grind?
Most durable installs start with mechanical profile. Skipping grind risks peeling on smooth or sealed concrete.
Epoxy vs polyaspartic?
Polyaspartic generally costs more, returns to service faster, and tolerates colder garages better than standard epoxy.
Will this hide oil stains?
Heavy oil often needs degreasing and hotspot repair first; coatings alone may telegraph contamination.
