In that case, drill some holes knock out some chunks, clean it out,
vacuum it, spray it with water, and float a layer of real crete on
top. 5,000psi with strands might work in a woodworking shop with
lighter machines, but you'll need a whole new floor for the big,
heavy, metalworking machines.

Yep. Ain't going to happen. Too much like work.

Got Fresh?


Well, actually the metalworking machines are not wearing the floor out, it's
the owner's constant pacing.

Grok that. So sit down in front of the machine, chip out a pad 0.5-1"
deep, sweep and vacuum it out, then pour a small fillup of patching
crete in there. Take a couple hours apiece. Duck soup, wot?
If you don't want to do the work, put a respirator on a local college
or high school kid (or Fresh!) and let them do it for you.

I suspect a rubber floor mat right in front of the machine is easier.

Oh? I thought you might want to fix any divots first.


Then you can wear out your pacing shoes, not the floor. It'll also
reduce the concrete dust you breathe, Joe, and that makes it all worth
doing.

Well, the dust is very coarse and stays on the floor until swept up. The dust
is basically fine sand coated with a little hardened cement.

That's great. Fine cement dust gets to me in a REAL hurry. I have to
put on the respirator before opening a bag of fence post mix.

Come to think of it, most of the old, broken-down cement I've seen is
fairly coarse. I work more with fresh bags, so that superfine stuff
was my mind's eye's first picture.


The big improvement in breathing came when I retired the last coolant mister and
went to dribble/flood cooling. Used to be that the shop air was a fog bank
after a few hours.

That can't be fun to breathe. Good move.
