🧪 Epoxy Calculator
Calculate the amount of epoxy resin needed based on floor area and coating thickness in mils.
How to Calculate Epoxy Coverage
At 100% solids, 1 gallon of epoxy covers approximately 1,604 sq ft at 1 mil thickness. For a typical garage floor coating of 10 mils, that is about 160 sq ft per gallon. Multiply by the number of coats (typically 2) for total material needed. Porous concrete may require a primer coat first.
Epoxy Thickness Guidelines
Thin-film coatings: 3–10 mils (decorative, light duty). Self-leveling epoxy: 10–20 mils (garage floors). Industrial coatings: 20–40 mils (warehouse, commercial). Always apply at manufacturer recommended spread rate. Temperature and humidity affect working time and cure.
