How to Epoxy a Garage Floor: Full DIY Guide (2026)
Transform your Toronto garage with durable, glossy epoxy. Step-by-step instructions for prep, application, and curing — plus pro tips for Ontario’s climate.
Why Epoxy Your Garage Floor?
Epoxy creates a seamless, high-gloss surface that resists oil, salt, and hot tires — perfect for Toronto winters.
- •Chemical Resistant: Oil, gas, and de-icing salts won’t stain.
- •Easy to Clean: Hose off dirt and grime.
- •Lasts for Years: With proper prep; in a garage the edges can start wearing after about 5 years, and a live crack comes back through any coating.

Why DIY garage floors fail (and how we fix them)
Why it happens: Garage paint and DIY kits sit on top of smooth, unprepared concrete. Hot tires lift them.
How we fix it: We grind off the failed coating, open the concrete, and lay a bonded epoxy and polyaspartic system.
Frequently Asked Questions
Can I epoxy over old paint?
No — must remove all paint. We offer grinding services.
How long before I can park?
With a DIY epoxy kit, follow the label — epoxy is usually fully cured in about a week at room temperature, longer in the cold. Our polyaspartic garage floors take cars after 48 hours and fully cure in 2 weeks.
Is polyaspartic better than epoxy?
Yes for topcoat — cures faster, UV-stable. Read our polyaspartic guide.
