When it comes to high-performance concrete coatings, polyaspartic has become a go-to for clients needing quick turnaround, durability, and a clean, modern finish. But while it offers major advantages in the right settings, it’s not the best choice for every project — especially for aviation hangars.
What Is Polyaspartic?
Polyaspartic is a fast-curing, UV-stable, polyurea-based coating that delivers:
- 1–2 hour cure times
- Excellent chemical and abrasion resistance
- Long-lasting clarity and flexibility
- Next-day return to service
It’s ideal for garages, patios, commercial spaces, and even industrial floors — but not every environment benefits equally.
Why Polyaspartic Isn’t Ideal for Aviation Hangars
In hangars or aircraft maintenance environments, a polyaspartic-only system simply doesn’t hold up the way a proper multi-layer epoxy system does. Here’s why:
Jet Fuel & Hydraulic Fluid Resistance:
Polyaspartics can resist many chemicals, but aviation-grade fluids like Skydrol and jet fuel can break them down over time. A 100% solids epoxy system with a urethane topcoat provides superior long-term resistance.
Film Build & Thickness:
Polyaspartic systems are often applied thin (8–12 mils). Hangar floors require heavier build coats (20–40+ mils) to withstand heavy equipment, impact, and chemical loads.
Layered Defense Matters:
A three-layer system — typically primer, 100% solids epoxy build coat, and urethane or polyaspartic topcoat — offers:
- Stronger chemical resistance
- Higher impact durability
- Longer service life
- Easier repair and maintenance
Cost vs. Longevity:
While polyaspartic is faster and often more expensive upfront, epoxy systems are more cost-effective over time in demanding environments like aviation hangars.
Bottom Line: Match the System to the Setting
Polyaspartic is a premium coating option for the right project — but in aviation, where fuel, fluid, and function are critical, a high-build epoxy system with proper layering is the gold standard.
