Looking to get my 3 car garage done with new garage flooring Arizona I've had 2 companies come out and both quoted the same price however two different products. One quoted a water-based epoxy top coat and the other a solid-based Polyaspartic top coat. From my research polyaspartic is a newer tech and higher gloss with UV resistance. seems to cost more generally but I was curious if we had any experts in here who can guide me in a direction.

The issue with both coatings is with age, they dull in color, change,  or on hot days peel off onto your car tires.

I personally am more of a concrete fan.  Esp if your garage gets the inevitable expansion/movement crack, can patch it up much easier than having to strip the coating to get down in th ere and fix and reapply.

Great point, g-man.

We have to deal with temperature fluctuations, water, and road salt.  The latter is probably the biggest concern regarding choice of flooring.

Agree  however our temp is always about the same.  When I lived in Rochester had a concrete garage with a nice drain, and could wash the car in the winter time.  Got rid of salt.  Yes garage was heated

I'm not a chemist or a technical expert but did spend 15 years in the epoxy business and dealt a little with polyaspartics too.  Epoxy is not UV stable, so if your garage gets much direct sunlight then that portion of the floor will be prone to color change and (eventually) cracking.  From what I recall, polyaspartics would generally be somewhat more brittle than epoxy but more resistant to UV degradation.  Polyaspartics cure very fast which may or may not be a good thing.
