Aviation facilities demand high-performance flooring that can withstand heavy loads, frequent traffic, and exposure to harsh chemicals like jet fuel and hydraulic fluids. Selecting the right epoxy coating—whether thin-mil or high-build—plays a crucial role in ensuring durability, safety, and long-term cost savings. This guide explores the differences between thin-mil and high-build epoxy to help you determine the best choice for your aviation flooring needs.

What is Thin-Mil Epoxy?

Thin-mil epoxy coatings are lightweight, durable solutions. They are composed of resin and hardener that cure into a seamless, glossy finish.

Best Applications for Thin-Mil Epoxy:

• Light-duty hangars and aircraft storage areas.
• Office and administrative sections within aviation facilities.
• Low-traffic zones where heavy impact resistance isn’t a top priority.

Benefits of Thin-Mil Epoxy:

• Cost-Effective: Requires fewer materials, making it a budget-friendly option.
• Quick Installation: Cures faster, minimizing downtime.
• Glossy Aesthetic: Provides a smooth, high-shine surface that enhances lighting.

Limitations of Thin-Mil Epoxy:

• Lower Durability: Less resistant to heavy aircraft loads and impact.
• Limited Chemical Resistance: May degrade over time with exposure to aviation fluids.
• Minimal Thickness: Offers less protection against cracks and wear.

What is High-Build Epoxy?

High-build epoxy coatings provide a thicker, more robust surface. These coatings are designed for heavy-duty use and can incorporate additives for enhanced strength, chemical resistance, and anti-slip properties.

Best Applications for High-Build Epoxy:

• Aircraft maintenance and repair hangars.
• High-traffic zones with frequent equipment movement.
• Areas exposed to fuels, oils, and corrosive substances.

Benefits of High-Build Epoxy:

• Superior Durability: Withstands heavy loads, dropped tools, and abrasions.
• High Chemical Resistance: Protects against aviation fuel, oil, and cleaning agents.
• Customizable Additives: Can include anti-slip textures and enhanced reflectivity.

Limitations of High-Build Epoxy:

• Longer Cure Time: Requires extended drying, increasing downtime.
• Higher Cost: More material and labor-intensive than thin-mil options.

Special Considerations for Aviation Flooring

• Fuel and Chemical Resistance: Hangar floors must resist harsh aviation fluids without degrading.
• Impact Resistance: High-build epoxy provides better protection against dropped tools and heavy equipment movement.
• Reflectivity: A well-lit hangar improves visibility and safety—glossy epoxy enhances this effect.
• Anti-Slip Solutions: While smooth epoxy is easy to clean, textured finishes help prevent slips and falls.

Selecting between thin-mil and high-build epoxy depends on the specific needs of your aviation facility. Thin-mil epoxy works well for light-duty areas, while high-build epoxy offers long-lasting protection in high-traffic, high-impact environments. Investing in the right flooring solution will enhance safety, maintain regulatory compliance, and ensure the longevity of your aviation facility.
