I did my 1500 square foot hangar when it was brand new with an off the shelf, locally available 2 part epoxy floor paint. I did it alone and without help or any previous knowledge. Washed the floor, did a muratic acid etch, rinsed the acid wash, allowed to dry and applied the epoxy. 12-15 years later it is doing great, it looks good and chicks dig it.
I think it cost me in the range of $300-400.
Only draw backs:
+the walk way where I drag the cub in with a tail dragger dragger, was slippery with snow on my feet and the floor. I redid a 3' wide walk way from the bi-fold door to the back wall where I walk when i pull it in, in this walk way I did it in a contrasting color with some rough course in it, as I recall it was a paint store available additive which was just ground walnut shells. It worked great! yes the oil drips in that segment are a bit harder to clean up, but not a big deal.
+it shows the dirt and proves I don't sweep as often as I should, it also shows poly-brush drips nicely.
+ I have a bit of flaking of from the concrete, like it was power screed too much, or too much calcium or something in the mix, anyway when it flakes off it obviously takes the epoxy coat with it, in the big picture no big deal.
Definitely wear a very good respirator! Buy several heavy duty paint rollers, commercial grade, I went through way too many cheap ones as the mixture is quite thick even at 80 degrees. A floor squeegee was useful as well.
You won't regret it, easy to do yourself.
