Epoxy Floor Coverage Calculator

Floor epoxy is planned from square footage, coats, and the coverage rate printed on the coating system. This page counts the gallons and kits to buy. For the installed price of a professional floor, use the epoxy garage floor cost calculator.

Looking for the installed price?

This calculator counts material. Professional quotes add surface prep, repairs, and labor, which usually make up most of the bill.

Installed price for garage and basement floors: $4–$10 per sq ft for professional epoxy, with DIY, flake, metallic, and polyaspartic compared.

Read mixed yield and coverage together

For 400 ft², two equal coats and a label rate of 160 ft² per mixed gallon per coat, raw quantity is 400 × 2 ÷ 160 = 5 gal. A 7% reserve gives 5.35 gal; 2 gal mixed-yield kits require three kits. This model repeats one product at one rate. If a primer, color coat and clear coat have different rates or prices, run each product separately and add their purchase plans.

Product data before mixing

Use the exact product documentation for mixing basis, maximum layer depth, mixed batch volume and cure or recoat conditions. A dimensional estimate and a purchase allowance do not supply those material limits.

FAQ

Questions people ask before buying epoxy

Why does this calculator ask for coverage rate?

Floor coating systems are usually sold with a published square-foot coverage range. That rate matters more than coat thickness entered in inches.

Should I include primer?

If primer is part of the material you are estimating, include it as an additional coat or run a separate calculation using its own coverage rate.

Can this calculate a garage floor?

Yes. For garage-specific numbers, use the epoxy garage floor cost calculator or the two-car garage epoxy calculator.
