Bought a new home in North, GA. I think I have finalized a space I will use for my shop, in addition to a single car garrage.... The area was a recreation room so it has carpet. I have spent too long on concrete floors. I am thinking about leaving the carpet, too ease stress on feet & legs. I was thinking about putting 1/4 or 3/8” pressed rubber mat down over the carpet as it comes in sizable rolls. I just put some in a puppy run as flooring and discovered that it can be hard to get some things off of due to the rough surface. Any suggestions about what to put over the carpet that will allow me to roll casters over the surface?
