Both are excellent floor coatings, but they are good at different things. Epoxy gives superior build and adhesion as a basecoat; polyaspartic cures fast and resists UV as a topcoat. The strongest floors use both.
| Feature | Epoxy | Polyaspartic |
|---|---|---|
| Cure time | 12-24 hrs per coat | 1-2 hrs per coat |
| UV stability | Can yellow in direct sun | Excellent, will not yellow |
| Strength & build | Superior build & adhesion | Thinner, more flexible |
| Best used as | Basecoat | Clear topcoat |
Polyaspartic is the better choice when speed and sunlight matter, like a one-day install or a floor that sees daylight. Epoxy is the better base when you want maximum thickness and bond to the concrete. For a garage in Ontario, you want both.
We install a hybrid system: a diamond-ground slab, an epoxy basecoat for adhesion, a decorative flake broadcast, and a UV-stable polyaspartic topcoat that handles freeze-thaw and hot tires. It is the best of both products in one floor.
