Super old and oily concrete brought back to life

This floor in an old mechanic shop had seen better days. The amount of grease residue was crazy. We cleaned it with a specialized detergent and coated it with a base layer of specialized epoxy to permanently block the oil from causing any issues. After that, we installed a beautiful flake floor over the surface using Gravel to match the other half of the building (which we completed a couple months ago)
