Epoxy Needed
Epoxy floor coating coverage depends on the product type and number of coats.
Gallons Needed = Floor Area / Coverage per Gallon × Number of Coats
Typical epoxy coverage rates:
- Standard epoxy paint: 200–300 sq ft per gallon per coat
- High-build epoxy: 100–150 sq ft per gallon per coat
- Epoxy kit (2-car garage): Covers ~250 sq ft per kit
Recommended coats:
- Minimum: 1 coat (basic protection)
- Standard: 2 coats (recommended for garages)
- Heavy-duty: 2 coats + topcoat (commercial/high-traffic)
Common garage sizes:
- 1-car garage: ~200 sq ft (12 × 16)
- 2-car garage: ~400 sq ft (20 × 20)
- 3-car garage: ~600 sq ft (30 × 20)
Application tips:
- Clean and etch concrete before applying
- Temperature should be 50–90°F (10–32°C)
