Well, if you would like it done, you can contact me through
Garage and Storage Plus of Austin. Actually, I am the general manager of the company, and I did this floor.
To answer some of the other questions, the Poly floor coating is a two-part solvent-based aliphatic urethane. I am a little lost when it comes to the underlying chemistry of this product, but so far it has been tough as nails. It has been strong, resists abrasion, cleans beautifully, and adhered without fail. The Poly is intended to coat architectural concrete. This product is used in garages and restaurants, but I doubt it would be appropriate for industrial facilities and that sort of thing.
And to answer ninjarico, The color in the concrete is actually *IN* the concrete--the stains are actually chemical deposits that bond molecularly with the concrete. It isn't a paint that can come off when adhesion fails.
As for jack stands, I would NEVER--regardless of any product put on a garage floor--use a jack stand on an expensive floor without a simple rubber mat. Just about the only thing that can mar a coated garage floor is a sharp object; a properly applied coating will shrug off everything else.
How durable is something like this versus say epoxy? Sorry if this is a rudimentary question but I'm not familiar with acid staining. What is the cost of something like this? I'll be moving into my first house (in round rock) come May and would love to have something like this done in the garage (20' x 20').
