Yea it was a 2 part epoxy they applied in the barn area. It's tough stuff. I accidentally drug a steel bench a few inches across it and you couldn't tell. I'm building some benches for the gun room this weekend to hold all my reloading equipment. The gun safe will also go in there as soon as i get some help to move it.
I understand needing help to move the gun safe. I am doing that tomorrow.
