okay, im using the shop my father built around 20 years ago on the backside of our garage. there was already a strip of concrete poured on the backside of garage the entire width and out three feet or so. so he formed up the new pad for the shop and connected it to the existing pad already there. dad floated it i guess for maximum traction and it is very rough i must say!
i have an office chair in the shop and the wheels are about wore down to the axles. i want to know is there a machine that can grid/sand the concrete surface down smooth? and what would i use to fill in the seam between the two pads? my mobile bases get caught up on it all the time and it makes for a big PITA!
i dont really want to move my TS or wood supply to grind/sand the floor but i can move the other tools around and then i would like to epoxy i guess after im done.
so main question is there a machine to grind/sand and what to use to fill in the gap?
thanks
