Present workshop has a concrete floor which wasn't power floated when

If I had a new floor, I'd want it power floated. Just to get a chance
to drive one of those "concrete hovercraft" that have two rotating
paddles, no other supports, and tank-like joystick steering. They look
like as much fun to drive as a mini-digger.

Otherwise for a smooth concrete floor, paint it. Epoxy isn't cheap,
but it's strong for machinery, seals the surface to leave it nice and
smooth and I bet it's still cheaper than a polishing machine.
