I had a local Epoxy company out to redo the epoxy in my garage. It had original epoxy flooring from 2006 and was pretty worn. Yesterday the guy prepped/sanded/etc and laid the epoxy and flakes. Today came back to do the polyurethane clear coat and was done after a couple hours. However I am not sure if the bubbles I am seeing is "normal" or if I am being too picky? I am hoping to get input from the community here. I did not pay the guy, which he was understandably upset at, so I need to decide quickly if I should pay him or what I should do. Attached are four photos of the finished product that is still slightly sticky and I was told will take another day to dry. I was told that the little dots are the anti-slip/grip functionality, which I first thought were bubbles, so I am mostly wondering about the actual bubbles that you can see in the photos. They are not everywhere but definitely there!

When I stick my head against my epoxy floor and look closely I see a few bubbles like you have. Not sure what they are from, but I did the floor, so I only have myself to blame. With that said, I only noticed them when I was down on the ground cleaning up a few oil drips. They haven't affected the floors performance and I don't notice them now that I have the tool boxes, welders, and hotrod back in the garage. I'd probably just pay him and move on. Maybe a little extra warranty is in order, but that's about it.

Did they use a primer?

Looks like what are called "Fisheyes" in automotive paint. From some type of contamination.
I had that happen on a new slap at my last house. I was told by the company that made the epoxy is was gas/air/vapor? I don't remember exactly coming up through the slap because of no vapor barrier. I just let it be at that point.

If the concrete was very porous and he placed 100% solids epoxy over the top (without a primer), this would be the likely culprit.
Another likely scenario is air-movement during install. This will cause the epoxy to skin-over before the under-coating has cured, trapping the escaping air that is exiting the porous concrete as the epoxy enters, causing a little volcano.

We see these infrequently and can come from many reasons as stated above, and often hard to pin down the culprit. Usually they can be popped and settle down and tended not to be noticed unless it's really bad which would require some prep and a recoat.
