If you’re shopping for a garage floor coating, you’ve probably come across both “epoxy” and “polyurea” or “polyaspartic” options. Understanding the difference can save you thousands of dollars and years of frustration.
What is Epoxy?
Epoxy is a thermosetting polymer that hardens when two components are mixed. The DIY kits you find at hardware stores use water-based epoxy — which means they’re only about 40–60% solids. The rest evaporates, leaving a thin, brittle film that bonds poorly to concrete and peels under hot tires.
What is Polyurea/Polyaspartic?
Polyurea is a flexible, high-strength elastomer. Our Polyurea base coat forms a molecular bond with the concrete substrate — it doesn’t sit on top of the concrete like epoxy. Our Polyaspartic topcoat (a type of polyurea) is:
- 100% UV stable (won’t yellow or fade)
- 100% antibacterial and antimicrobial
- 4x stronger than standard epoxy
- Completely cured in one day
The Bottom Line
If you want a floor that lasts 15+ years with a warranty to match, choose professional polyaspartic. If you want to recoat in 2–3 years, choose DIY epoxy. The choice is easy.
