Polyaspartic vs Epoxy — Which Wins on Edmonton Garages?
Both are pro garage-floor coatings. Both look great. Both cost roughly the same installed. So which one is right for your driveway? Here's the honest, side-by-side comparison from a crew that installs both every week.
TL;DR — When to Choose Each
Choose Epoxy if…
- You're working to a tighter budget
- Your garage doesn't see direct UV (north-facing or shaded)
- You can give the floor 5–7 days to fully cure
- You want maximum chemical resistance for hobby/auto work
Choose Polyaspartic if…
- You need to park on it within 24 hours
- Direct sun hits the floor (south/west facing)
- You're booking a winter install (cures in cold)
- You want longest possible service life
Detailed Spec Comparison
| Spec | Epoxy | Polyaspartic |
|---|---|---|
| Installed cost (per sq ft) | $6.50 – $9.00 | $8.50 – $11.00 |
| Cure time (foot) | 12–24 h | 2–4 h |
| Cure time (vehicles) | 5–7 days | 24 h |
| UV resistance (yellowing) | Will yellow in direct sun | Excellent — won't yellow |
| Cold-temp install | Min ~10°C | Down to -5°C |
| Chemical resistance | Excellent (best for shop) | Very good |
| Abrasion / scratch | Good | Excellent |
| Lifespan in Edmonton garage | 15–20 yr | 20–25 yr |
| Repairability | Easy to recoat | Specialist tools needed |
| Smell during install | Mild | Stronger (mask up) |
Which One Lasts Longer in Alberta's Climate?
Real-world: polyaspartic outlives epoxy by ~5 years in Edmonton garages. Three reasons:
- UV stability. Sunlight pouring through your garage door yellows pure epoxy within 5–7 years. Polyaspartic stays clear forever.
- Flex and movement. Polyaspartic stays slightly elastic — concrete can move with frost heaves and the coating won't crack.
- Hot-tire pickup. Cheap epoxy fails when hot summer tires roll onto it from the driveway. Polyaspartic doesn't.
That said: a hybrid floor (epoxy basecoat + polyaspartic topcoat) gets you both — and is barely any more expensive than polyaspartic-only because the cheaper epoxy basecoat carries the bulk of the build.
Honest Downsides of Polyaspartic
Working Time
Polyaspartic kicks in 15–25 min. We need a bigger crew to lay down a 600 sq ft garage before it sets.
Stronger Smell
The amine catalyst smells stronger than epoxy. Plan to be out of the house for the install day.
Higher Sticker Price
Polyaspartic-only systems run 25–35% more than epoxy-only. The extra lifespan covers it — but the cheque is bigger up front.
Polyaspartic vs Epoxy — FAQ
Is polyaspartic better than epoxy?+
For Edmonton garage floors specifically, polyaspartic edges out pure epoxy on UV resistance, cure time, and lifespan — but costs ~25–35% more. The best value is usually a hybrid system: epoxy basecoat (deep color, strong bond, lower cost) topped with polyaspartic (UV-stable, fast cure).
How fast can I park on a polyaspartic floor?+
Pure polyaspartic systems cure to foot traffic in 2–4 hours and vehicles in 24 hours. That's why it's the go-to for retail spaces that can't be closed for a week. Epoxy needs 5–7 days for full vehicle cure.
Does polyaspartic yellow in sunlight?+
No. Polyaspartic is UV-stable by design. Epoxy will gradually yellow in direct sun (most noticeable on white/grey solid colors). If your garage has lots of natural light or you keep the door open in summer, polyaspartic or a hybrid topcoat is the safer call.
Can polyaspartic be installed in winter?+
Yes — down to about -5°C, which is rare for garage coatings. We can install January through March in heated garages or under tarps + heaters. Epoxy needs a minimum ~10°C ambient and slab temperature.
Is polyaspartic worth the extra money?+
For a daily-driver garage that sees salt and hot tires? Yes. The extra 5+ years of life and the no-yellowing finish more than cover the price gap. For a shaded basement or hobby room without UV, plain epoxy is fine and saves money.
