Can polyaspartic coatings resist aviation fluid spills in my Ottawa hangar?

Yes, polyaspartic coatings can resist aviation fluid spills, but you'll need a specialized high-performance system designed specifically for aircraft hangar environments. Standard residential polyaspartic formulations may not provide adequate protection against the aggressive chemicals found in aviation fuels, hydraulic fluids, and de-icing compounds.

Aviation Hangar Floor Requirements

Aircraft hangars present unique challenges that go far beyond typical garage or commercial flooring needs. Aviation fuels like Jet A-1 and 100LL contain aromatic hydrocarbons that can soften or dissolve inadequately specified coatings. Hydraulic fluids (Skydrol and mineral-based systems) are particularly aggressive, while de-icing fluids like propylene glycol can penetrate coating systems over time. Your hangar floor needs a chemical-resistant polyaspartic system with specialized additives or a multi-coat system that includes a chemical-resistant primer and topcoat.

High-performance polyaspartic systems for aviation use typically incorporate novolac epoxy primers for maximum chemical resistance, followed by aliphatic polyaspartic topcoats that provide UV stability and rapid return to service. Some systems include polyurea interlayers for enhanced flexibility and impact resistance from dropped tools or equipment. The coating thickness is critical – aviation applications typically require 15 to 25 mils total system thickness compared to 8 to 12 mils for standard garage floors.

In Ottawa's climate, you'll pay between $12 and $25 per square foot for a properly specified aviation hangar floor system, significantly higher than residential applications due to the specialized materials and surface preparation requirements. The concrete substrate must be diamond ground to achieve a concrete surface profile (CSP) of 3 to 4, and moisture testing is absolutely critical – aviation coatings are less forgiving of moisture vapor transmission than standard systems.

Temperature control during application is essential in Ottawa hangars, as most aviation-grade polyaspartic systems require consistent temperatures between 15 and 25 degrees Celsius throughout the entire cure cycle. Winter applications in unheated hangars are generally not feasible unless temporary heating can maintain proper conditions for 48 to 72 hours.

For a project of this complexity and the liability involved with aviation applications, you should consult with contractors experienced in industrial and aviation flooring through the Ottawa Construction Network directory at justynrookcontracting.com, specifically looking for those with Transport Canada or aviation industry experience.
