Common Operational Challenges
Physical and chemical factors that dictate surface preparation and system selection in this environment:
- •Aggressive Skydrol and aviation hydraulic fluids that instantly blister conventional epoxy systems
- •Extreme static and rolling point-loads from aircraft landing gear, tow tractors, and jacking gear
- •High-reflectivity floor requirements to bounce light upward onto aircraft underwings during maintenance
- •Fuel spills, de-icing chemicals, and engine exhaust heat on tarmac parking aprons
- •Strict foreign object debris (FOD) prevention during surface grinding and coating installations
Compliance & Quality Benchmarks
Technical standards and regional regulatory frameworks relevant to coating and safety specifications for this sector:
Substrate Preparation, Coating Chemistry & Maintenance Protocols
Aviation Maintenance Standards and Airfield Safety Operations#
Aircraft hangars, general aviation maintenance bases, and military airfields at Jomo Kenyatta International Airport (JKIA), Wilson Airport, Moi International Airport Mombasa, and regional aerodromes in Eldoret, Kisumu, and Malindi demand extraordinary flooring and marking precision. Aviation facilities operate under strict Kenya Civil Aviation Authority (KCAA) and International Civil Aviation Organization (ICAO) rules. Flooring must survive aggressive aviation hydraulic fluids, support massive aircraft landing gear wheel loads, and ensure zero Foreign Object Debris (FOD) risk. Sienna provides military and commercial aviation facility contracting.
Skydrol Hydraulic Fluid Resistance and Chemical Barrier Technology#
Phosphate ester hydraulic fluids such as Skydrol and HyJet are standard in modern aviation hydraulics. When Skydrol leaks onto conventional epoxy or industrial polyurethane, it acts as a powerful paint stripper, softening the resin within hours and destroying concrete adhesion. Sienna installs specialized polyurethane screeds and high-density polyaspartic coatings specifically engineered with chemical resistance against phosphate esters, allowing technicians to wipe up hydraulic leaks with zero floor damage.
Light Reflectivity for Aircraft Underwing Maintenance#
Aviation maintenance, repair, and overhaul (MRO) technicians work on complex avionics, landing gear linkages, and fuselage undersides where ambient lighting is blocked. We formulate aircraft hangar floors with high-gloss, ultra-reflective white or light-grey finishes that bounce up to 85 percent of overhead hangar lighting directly back onto aircraft bellies. This drastically improves technician visibility, enhances safety, and lowers hangar electrical power consumption.
ICAO and KCAA Compliant Apron and Runway Line Demarcation#
Airfield taxiways, aircraft parking bays, marshalling lanes, and helicopter landing pads require precise chromatic and retro-reflective markings compliant with ICAO Annex 14. We apply high-build acrylic and chlorinated rubber aerodrome paints embedded with high-index glass beads for night-time retro-reflectivity, utilizing computerized striper units that ensure razor-sharp edges and exact regulation line widths.

Frequently Asked Questions : Aviation Facilities, Aircraft Hangars & Airfields
Conventional epoxies dissolve under Skydrol phosphate ester fluid. We specify specialized chemical-resistant aliphatic polyurethane and polyaspartic resin topcoats whose dense polymer matrix is immune to phosphate ester softening, enabling technicians to clean hydraulic leaks without floor blister.
We operate strict FOD control protocols in compliance with KCAA aerodrome safety: fully enclosed vacuum diamond grinders that capture 99.9% of dust, magnetic sweepers to collect metal pins, tool inventory logs, and mandatory daily airside zone inspections before handovers.
Yes. Our aviation floor systems achieve compressive strengths exceeding 60 to 80 N/mm2, far surpassing structural concrete screeds. This withstands concentrated point loads from narrow nose gear tyres, heavy aircraft hydraulic jacks, and tug tractors without cracking.
A high-gloss white or light grey floor reflects up to 85 percent of overhead luminaire light upward into the dark underside of aircraft fuselages and wings. This drastically reduces the need for auxiliary portable work lights, eliminates shadows, and improves inspection accuracy for maintenance engineers.
Yes. We calibrate all aerodrome markings to exact ICAO Annex 14 and KCAA specifications for chromaticity, line width, and retro-reflectivity using certified aviation road marking paints and high-refractive glass beads for clear night-time pilot visibility.
Using our rapid-cure polyaspartic and fast-set polyurethane systems, the floor is ready for light foot traffic within 12 hours and can support full aircraft towing, parking, and maintenance operations within 48 to 72 hours under Kenyan ambient conditions.
Yes. We install seamless conductive and electrostatic dissipative (ESD) epoxy flooring interconnected with copper grounding grids for specialized avionics workshops and cleanroom radar repair facilities, preventing electrostatic damage to delicate airborne electronic cards.
