Frequently Asked Questions
How many gallons of epoxy for a 400 sq ft garage at 10 mils?
Gal/coat = 400 x (10 x 0.001 / 12) x 7.481 = 2.49 gal. Two coats with 10% waste = 5.48 gal total. Round up to 6 gallons or 4 kits of 1.5 gal.
What is a mil in epoxy coating?
1 mil = 0.001 inch (one thousandth of an inch). Standard floor epoxy applies at 6-10 mils per coat. 10 mils is about the thickness of a credit card.
How many coats of epoxy does a garage floor need?
Typically 2 coats: a base coat and a topcoat. Some systems use a primer, base coat, and clear topcoat (3 coats) for maximum durability.
How do I calculate coverage per gallon for epoxy?
Coverage = 1,604 x spread rate in mils / 1 gallon (theoretical). At 10 mils: 1,604 / 10 = 160 sq ft/gal theoretical. Expect 130-150 sq ft/gal practical with waste.
