THE HONEST VERDICT
Real epoxy is a two-part chemical cure poured many times thicker than paint, over a diamond-ground slab. That's the whole difference between four months and fifteen years.

EPOXY VS FLOOR PAINT
Big-box floor paint and a DIY kit look great for a season. Then the hot tires lift it, and the peeling starts at the door.
| Epoxy | Garage floor paint | |
|---|---|---|
| Thickness | 20–60+ mils | 3–5 mils |
| Prep | Diamond grinding | Etch or nothing |
| Hot tire pickup | Resistant | Common failure |
| Lifespan | 15–20+ years | 1–3 years |
| Repair | Spot repair and recoat | Strip and start over |

WHEN GARAGE FLOOR PAINT IS THE RIGHT CALL
There isn't really a case for paint on a slab you care about.
GOOD TO KNOW
- Why did my DIY epoxy kit peel?
- Almost always prep. Big-box kits rely on acid etching, which doesn't open a hard-troweled slab. Without a ground profile the resin has nothing to grip.
- Can you fix a failing painted floor?
- Yes — we grind the old coating completely off, repair what's underneath and pour a proper system over it.
