Epoxy Calculator — Kits, Coverage & Flakes
Calculate epoxy floor coating kits needed by area, thickness, and epoxy type. 100% solids, water-based, solvent-based, and self-leveling have different coverage rates. Includes decorative flake coverage and cost estimation for garage and commercial floors.
Why This Construction Metric Matters
Why: Epoxy floor coatings provide durable, chemical-resistant surfaces for garages, workshops, and commercial floors. Coverage varies by type—100% solids covers ~120 sq ft/gal at 10 mils; water-based ~150. Thickness affects durability and cost. Flakes add decorative finish and slip resistance.
How: Area = Length × Width. Volume = Area × Thickness (mils) ÷ 1000 × coverage factor. Kits = Volume ÷ Kit coverage. Coverage: 100% solids ~120 sq ft/gal at 10 mils, water-based ~150, solvent ~130. Flakes: ~1-2 lbs per 100 sq ft for light coverage, 3-5 for full.
- ●100% solids: ~120 sq ft/gal at 10 mils, zero VOC, max durability.
- ●Water-based: ~150 sq ft/gal, low odor, good for residential.
- ●Surface prep critical—etch or grind for adhesion.
- ●Flakes: 1-2 lbs/100 sq ft light; 3-5 lbs full coverage.
