Epoxy Coverage
Estimate two-part epoxy for a garage or floor.
About Epoxy Coverage
Epoxy coverage is the floor area times the coats and a waste allowance, divided by coverage per gallon. Because epoxy comes in two-part kits, the result also rounds into kits. Garage epoxy is sold in paired kits, so converting gallon needs into full kits prevents partial-order mistakes.
Formula
Epoxy Coverage
Gallons = area x coats x (1 + waste) / coverage
- coat
- One layer of the two-part epoxy

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
