Rarely is this across the entire floor typically it s is in isolated sections. So that means most floor epoxies have a higher crush rating than the concrete it s going on. First they can be caused by air trapped below the coating in tiny surface voids. It can also hurt the physical performance properties of the epoxy.

If conditions are too cold or direct sunlight hits your curing resin you could see bubbles. The most common reasons this occurs is improper preparation of the epoxy or applying the epoxy when the temperature is too hot or cold or the humidity is too high.
