Aircraft Hangar Flooring in Granbury, TX
Hangar floor coating for private, corporate, and small-airport hangars across Granbury, Weatherford, Stephenville, Glen Rose, Aledo & the southwest Fort Worth area. A light, reflective, chemical-resistant floor built the way hangar floors are actually specified, starting with a moisture reading on your slab.
What the floor has to do
A hangar floor has a different job list
The Department of Defense publishes design criteria for maintenance hangars, and while your hangar is not a military one, the requirements are the same problems in the same building. Four of them drive the system.
It has to survive what gets spilled
Jet fuel, motor oil, brake fluid, and hydraulic fluid. Bare concrete is porous and absorbs all of it permanently, so the only protection is a barrier that does not care.
It has to make small parts visible
This is the one people outside aviation miss. Hangar floors are specified light gray so dropped hardware, safety wire, and small parts contrast sharply against the surface. Foreign object debris is a safety problem, and a dark or busy floor hides exactly what you need to find. A reflective floor also cuts how many light fixtures the building needs to hit the same working brightness.
It has to take impact and abrasion
Dropped tools and parts, plus the hard wheels of stands, carts, tugs, and jacks rolling across it all day. That is a different kind of wear than foot traffic.
It has to stay easy to sweep
And this one pulls against slip resistance, which we will get to.
The chemical question
Skydrol, and what actually resists it
Skydrol is aggressive on coatings, and it is the reason a hangar floor cannot be ordinary floor paint.
The company that makes it publishes a material compatibility table, and the ratings are clear. Epoxy rates excellent, meaning it can stay in constant contact. Urethane rates good, withstanding exposure with minimum loss of integrity. At the other end, acrylic, asphaltic, and lacquer finishes have no resistance and disintegrate in the fluid, and alkyd, latex, and varnish rate poor.
Two honest notes on that. First, the table covers broad chemistry classes rather than specific floor products, so the actual product's own chemical resistance chart is what matters on your job, and we will show it to you. Second, it means epoxy is the better performer against Skydrol, not urethane. Urethane goes on top for abrasion resistance, gloss retention, and tire staining, which is a different argument.
Worth knowing about tire staining: aircraft and tug tires can leach plasticizers into a coating and leave marks, sometimes called paw printing. That is a staining problem rather than a coating failure, and the topcoat is what resists it.
Start with the slab
Moisture is what actually kills hangar floors
If a hangar floor is going to fail, this is usually why, and the military's own criteria say so plainly.
The thin-film hangar system, the criteria note, has had delamination problems because of its intolerance to moisture coming up through the concrete. They go further and say the maximum allowable emission rate is difficult to attain on many slabs. That is an unusually candid admission in a government specification, and it matches what we see on every large slab on grade.
Hangar slabs are big, poured on grade, and frequently built without a vapor barrier underneath. Water vapor moves up through the concrete, reaches the coating, has nowhere to go, and pushes it off the slab. On a garage that is a nuisance. On a hangar it is the floor.
So we grind a section and meter the concrete before we commit to a system, and we write the reading down. If your slab reads high, that fact chooses your floor, and we would far rather find it in the quote than in a callback.
What goes down
The hangar floor system
- Mechanically prepare the slab. Shot blast or diamond grind to an open profile so the primer keys into the concrete rather than sitting on it.
- Meter the concrete for moisture. The reading goes on your paperwork and decides the system.
- Epoxy primer, built to thickness. The layer against the slab, doing the adhesion and the chemical resistance.
- Urethane topcoats. Two of them, for abrasion resistance, gloss retention, and cleanability. A light gray or similar reflective color so parts stay visible.
- Aluminum oxide grit, broadcast into the final topcoat where you want traction.
Why not flake or quartz? Because a hangar is the one building where we would talk you out of it. Hangar specifications call for a fine aluminum oxide grit rather than a quartz or flake broadcast, and the reason is in the spec itself: there is a fine line between slippery and hard to clean, and higher grit levels make cleaning harder. A heavy decorative broadcast traps dirt and works against the smooth, light, sweepable surface that makes small parts visible. If you want flake, we will install it, but you should know the tradeoff you are making.
Setting expectations
What a coating does and does not do
The slab carries the aircraft, not the coating. Hangar slabs are engineered for aircraft wheel loads, tug loads, and jacking, and no coating changes that. If your slab is undersized or cracking from movement, a coating puts a nicer surface on the same problem. What the coating handles is impact and abrasion, which is the wear you actually see day to day.
Thin-film systems get recoated. A three-coat hangar floor is a maintenance item, not a permanent one. The heavier five-coat builds with an epoxy mortar layer cost considerably more up front and go much longer between recoats. Which one makes sense depends on how hard your hangar works and how long you plan to hold the building, and we will lay both out rather than quoting one.
We do not claim de-icing fluid resistance. It does not appear in the hangar criteria or in the published chemical resistance lists we work from. If that matters for your operation, tell us and we will get it in writing from the manufacturer or tell you we cannot.
Straight answer
Private hangars, not federal contracts
Federal and military hangar work requires SSPC QP 8 contractor certification before a contract is awarded, along with a certified coating inspector. We do not hold that certification, so we do not bid that work.
What we do coat is private hangars, corporate hangars, and hangars at small and general aviation fields, where that requirement does not apply. We read the same criteria the federal specs are built on because the building has the same problems, but we will not imply a qualification we do not have.
Tell us about the hangar
Square footage, what gets worked on in it, what gets spilled, and how much downtime you can give us. We walk hangar floors across Granbury, Weatherford, Stephenville, Glen Rose, Aledo & the southwest Fort Worth area and put the system, the moisture reading, and the schedule in writing before you commit to anything.
