Uneven floor color

[PRO.OUTLAW]

Hello all! I just recently finished having a epoxy floor installed. I went to the shop after 24 hours only to find that the color was very uneven. Its 1800sqf of LT grey and no flakes. The floor was diamond ground, primered, sanded, cracks filled and then the epoxy put down with a squeege and roller. Im interested in trying to find out what happened before I speak to the installer. Thanks
