Epoxy Floor Coating Calculator

Calculate how much epoxy you need to coat a floor.

Epoxy Needed
— gallons
For all coats.

Usage Tip

Mix only what you can spread within the pot life printed on the kit; epoxy hardens in the bucket once combined.

THE MATH
gallons = floor area × coats ÷ coverage rate
Epoxy floor coating is measured like paint: gallons equal the floor area times the coats divided by the coverage rate. A primer or top coat counts as another coat.
Enter the floor area, the coverage per gallon, and the number of coats.
Garage floors usually get two coats; high-traffic floors get three.
