Estimate two-part epoxy for a garage or floor.
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.
