Jason and his crew at TNT finished the floor of our hangar. The floor was previously painted, had numerous cracks, and was oil stained. They stripped, sandblasted, and ground the floor smooth. They filled all the cracks and joints flush. There were some imperfections in the epoxy coat that weren't up to Jason's standards, so they sanded it down and re-did it. I'm very pleased with the outcome. I had other quotes and TNT was the best value.
