Epoxy vs. Polyaspartic: Which Floor Coating Lasts Longer?
Homeowners from Provo to Salt Lake City often ask us the same question: “Should I choose epoxy or polyaspartic for my garage or shop floor?” Both coatings are strong, long-lasting, and a major upgrade over bare concrete. But they’re not the same—especially in Utah’s freeze-thaw climate.
What Is Epoxy?
Epoxy is a two-part resin system that bonds tightly to concrete and creates a hard, durable surface. It’s been used for decades in garages, warehouses, shops, and commercial spaces.
Epoxy Strengths
- Excellent adhesion to concrete
- Thick, rigid surface that holds up in high-use areas
- Wide color and flake options
- Budget-friendly for homeowners
- Great for basements, workshops, and indoor spaces
Where Epoxy Falls Short
- Can amber or yellow in UV exposure (garage doors open often = faster discoloration)
- Longer cure time — usually 24–72 hours before use
- More prone to cracking in extreme temperature swings
In Utah County and the Wasatch Front, where temps jump drastically between seasons, that rigidity can lead to surface stress over time.
What Is Polyaspartic?
Polyaspartic is a next-generation coating known for being extremely durable, flexible, and UV stable. It’s popular for garage floors, patios, shops, and commercial spaces that need fast return-to-service.
Polyaspartic Strengths
- Superior UV resistance — won’t yellow or fade
- Faster cure time — often walkable in a few hours
- High flexibility — better handles freeze-thaw movement
- Excellent chemical and abrasion resistance
- Long lifespan with minimal maintenance
- Great for both residential and industrial settings
Where Polyaspartic Falls Short
- Higher upfront cost
- Requires a trained crew for consistent installation
- Not ideal for DIY due to rapid working time
Which Coating Lasts Longer?
Polyaspartic typically outlasts epoxy, especially in climates with wide temperature swings like northern Utah.
Why Polyaspartic Wins for Longevity
- UV stability: No fading, ambering, or gloss loss.
- Flexibility: Moves with the concrete, reducing cracking.
- Higher chemical resistance: Resists salt, oil, gas, and winter melt-off — all common on Utah garage floors.
- Faster cure: Less chance for dust or debris to compromise the surface.
While epoxy still offers great durability—often 5–10 years with proper prep—polyaspartic can push 10–20 years with professional installation and routine care.
Cost Comparison
Pricing varies depending on the condition of the concrete, size of the space, and chosen flake/blend. Typical ranges:
- Epoxy: $4–$7 per sq. ft.
- Polyaspartic: $6–$10 per sq. ft.
Utah homeowners often choose polyaspartic for garages and patios because the long-term value outweighs the upfront difference.
What About a Hybrid System?
Many high-performance floors use epoxy as a base coat and polyaspartic as a topcoat, giving the best of both worlds:
- Strong adhesion from epoxy
- UV-stable, flexible protection from polyaspartic
- Premium durability for shops, hangars, and busy garages
Hermetic Coatings installs hybrid systems often for Lehi, Saratoga Springs, and Salt Lake City customers needing heavy-duty performance.
Which Coating Should You Choose?
Choose epoxy if:
- Budget is the top priority
- The space is indoors or receives minimal sunlight
- You want a rigid, tough surface for controlled environments
Choose polyaspartic if:
- Your garage gets full sun
- You want maximum longevity
- You need fast turnaround
- The floor sees harsh use, chemicals, or Utah’s winter moisture
Final Takeaway
Both epoxy and polyaspartic coatings deliver strong, attractive floors—but for long-term durability, UV protection, and weather resistance across the Wasatch Front, polyaspartic is the clear winner.
