Epoxy floor calculator
Two-part epoxy for garage floors covers about 250 sq ft per gallon — significantly less than acrylic concrete paint. Honest take: most homeowners don't actually need epoxy. Kompozit STRONG acrylic concrete paint covers the same use case with way less hassle and roughly half the cost. We'll show you both numbers below.
Estimates round up to the nearest quart and are based on Kompozit's published coverage. Buy slightly more for touch-ups and color changes.
When epoxy is worth the hassle
2-part epoxy makes sense for commercial garages, mechanic shops, or floors that take real chemical exposure (battery acid, brake fluid, hydraulic oil). The film is harder, more chemical-resistant, and will not soften under hot tires the way cheap concrete paints do.
Why STRONG acrylic is usually enough
For DIY garages, basements, patios, and home workshops: Kompozit STRONG acrylic is much easier to apply (no mixing, no time pressure, no fumes), costs roughly half as much per sq ft, and lasts 7–10 years on a properly prepped slab. The "you must use epoxy" advice is marketing — STRONG handles the same use cases for the same lifespan when prep is right.
Prep is everything
Acid etch or grind the slab. Test for moisture (tape a 2'×2' plastic sheet for 24 hours, check for condensation). Vacuum, repair cracks, and let everything dry. The single biggest reason garage floor coatings fail is rushed prep, regardless of whether you used epoxy or acrylic.
FAQ
The cured film is water-resistant, but it doesn't fix moisture coming up through the slab. Hydrostatic vapor will lift epoxy just like it lifts acrylic. Address moisture first.
