Pittsburgh Aviation: Hangar Floor Coating Built for the Chemistry
Standard industrial epoxy fails fast in a working hangar. Pittsburgh Concrete specs and installs aviation-rated floor coating systems matched to your exact fluid exposure, from Jet A and Skydrol to winter glycol de-icers, with slab prep and joint detail done right. Free written estimate on every project.
Why Hangar Floor Coating Needs Its Own Specification
A warehouse floor and a hangar floor are both concrete slabs, but the chemical exposure profile is completely different. Skydrol hydraulic fluid, used in most modern commercial and corporate aircraft, is highly reactive and will break down a standard epoxy coating within months of regular contact. Jet A and avgas present their own degradation risks, and Pittsburgh's winter maintenance season adds glycol-based de-icing fluid to the mix. A properly specified hangar floor coating addresses all three fluid categories in a single system, typically a urethane cement for severe Skydrol environments or an aviation-grade epoxy where the exposure is lighter.
Slab condition matters as much as system selection. Older hangar concrete often carries years of absorbed fuel and fluid contamination that must be remediated before any coating bonds correctly. Diamond grinding opens the surface profile, contaminated zones get cut back to clean concrete, and existing cracks are repaired with high-strength bonded material before the coating goes down. Skipping that prep is the most common reason hangar coatings fail early.
From Slab Assessment to Finished Hangar Floor: The Installation Sequence
Map the fluid exposure
Before any product is selected, we sit down with maintenance operations to document every fluid the hangar handles: Jet A, avgas, Skydrol grade, hydraulic fluid type, de-icing compound, and cleaning chemistry. Spill frequency and dwell time factor into the system spec. A corporate jet hangar with occasional Skydrol contact gets a different coating than an MRO bay where hydraulic fluid is on the floor daily.
Prep the concrete slab
Diamond grinding brings the slab surface to the correct profile for the chosen system. Zones with deep fuel or fluid penetration are assessed for remediation depth; in some cases, the top layer of contaminated concrete is removed entirely. Cracks are routed and filled with bonded repair material rated for the same chemical exposure as the coating above it.
Apply the aviation-rated coating
The specified system goes down at engineered thickness. Urethane cement is the standard choice where Skydrol contact is regular; aviation-grade epoxy covers facilities with lighter chemical exposure. Aggregate is broadcast into the wet coating at service lanes and tow paths to meet slip-resistance requirements without reducing chemical performance.
Fill joints, apply topcoat, and document
Control joints are filled with chemical-resistant semi-rigid filler rated for aviation fluids, not standard polyurea. The topcoat seals the system and provides the final surface hardness. Chemical-resistance ratings and product data sheets are compiled into a facility record for compliance review or future maintenance reference.
Aircraft tow loads
The Load Case Most Hangar Floors Fail: Tow Tractor Point Loads
Aircraft weight is distributed across multiple landing gear positions, which spreads the load across a large slab area. A tow tractor is a different problem entirely. Small solid rubber wheels concentrate several tons of tractor-plus-aircraft weight into a contact patch measured in square inches, and that load reverses direction at every turn. The coating at tow path corners and pivot points takes far more punishment than the concrete sitting under a parked Citation or King Air. We size the coating system and slab reinforcement for tow tractor loads as the governing case, which means the floor is more than adequate everywhere else.
Parked aircraft tire contact zones also get attention during layout. A heavy twin or turboprop sitting in the same spot for weeks creates sustained point loading that a thin or poorly bonded coating will eventually telegraph as delamination. Knowing the aircraft types that will use the hangar lets us reinforce those specific zones during installation rather than discovering the problem two years later.
Your Hangar Floor Coating Questions, Plain Answers
Skydrol resistance, tow tractor loads, joint fillers and aviation compliance.
Aviation chemicals (especially Skydrol) attack standard epoxy systems aggressively. Combined with tow tractor point loads and aircraft tire contact patches, the spec has to match a unique exposure profile that other commercial floors do not see.
If the hangar handles aircraft with Skydrol hydraulic systems (most modern commercial and many corporate), yes. Skydrol-rated urethane cement is the typical answer; the wrong system dissolves quickly under Skydrol contact.
Glycol-based de-icing fluids are part of the chemical exposure profile in Pittsburgh hangars. We spec the system for those alongside the aviation hydraulics so winter operations do not degrade the floor.
Yes, the joint filler has to be chemical-resistant to the same aviation fluids the coating handles. Standard polyurea filler can degrade under Skydrol; we use chemical-resistant variants in aviation environments.
A typical hangar takes a week or two from prep through cure, with the hangar offline during the work. Larger MRO facilities stretch to multi-week phased installs. The schedule is built around maintenance operations.

What Pittsburgh Operations Say About Their Hangar Floors
Skydrol-rated urethane install in our maintenance hangar. Three years of regular hydraulic spills, zero coating failure at any spill point. Worth the spec premium over standard epoxy.

FBO Manager, Pittsburgh Airport
★★★★★
Engineered for our tow tractor loads, not just aircraft loads. The coating has held perfectly at every tow turn point, where the previous floor had failed within months.
Y. A5
MRO Operations, Aliquippa
★★★★★
Coordinated install during a scheduled maintenance downtime. Hangar offline only for the cure window, back in service on schedule. Real coordination with operations.
Q. A5
Corporate Hangar Owner, Monroeville
★★★★★
Documented chemical-resistance rating for our facility compliance file. Auditor accepted without questions. The documentation matters in aviation.
