EPOXY VS. POLYASPARTIC GARAGE FLOOR COATINGS: WHICH IS BETTER?
Spoiler: the best systems use both. Epoxy as the base coat, polyaspartic as the topcoat. Here's why.
EPOXY: THE BASE COAT
Epoxy is thick, builds up the surface, fills minor imperfections, and bonds extremely well to properly prepped concrete. But pure epoxy yellows in UV light and is slower to cure (full cure can take a week).
POLYASPARTIC: THE TOPCOAT
Polyaspartic is UV-stable (won't yellow), more flexible (better for slabs that move), and cures fast — drive on it in 24–48 hours. But polyaspartic alone is thinner and more expensive per gallon.
THE BEST OF BOTH
A premium garage floor system uses an epoxy base coat for build and bond, decorative flake or metallic broadcast for looks and slip resistance, then a polyaspartic topcoat for UV stability and fast cure. This is the system Becker Flooring installs.
WHEN TO SKIP ONE
100% polyaspartic systems exist and are good for fast turnarounds (1-day installs) but cost 30–40% more. 100% epoxy systems are the budget option and fine for indoor use only (no UV exposure). For a Kelowna garage with sun exposure through open doors, the epoxy + polyaspartic combo is the sweet spot.
