My bay floors are all chewed up from years of harsh chemical in the wash, has anyone ever concrete polished your floors or done something to make them look good. Epoxy I think would get eaten up after a year of harsh chemicals but concrete polishing is really just polished concrete. Anyone do anything to your floors to make them look better?

There was a company at the show that had a 2 part epoxy with some type of abrasive media in it. Looked interesting.

Company / Product called Tufco

I'm pretty sure they can only "polish" concrete when it's still wet, for example most garage floors have been paddle-polished after it's poured to make them smooth. You really don't want to do that on sloped bay floors because they'd be slippery.

There might be someone who knows how to grind them smooth.

They can grind it down to where it has like a rougher texture to it so its almost grip tap feel, my only worry is that will cause it to be more porous to chemicals and will eat it away over time.

I had a wash where the floor was all pitted and rough. I rented a floor concrete grinder from a local rental place and made a huge difference. Its much easier to wash the bays down and sweep. Grinding the floor makes it smoother not rougher. At work they grind the floors and polish them to almost a mirror finish. The grinders use diamond blades. I did 4 bays in like 6 hours.

Did you use different grits of diamond blades or just one grit to make it smooth?

I just used one grit. The blades were like triangle wedges that attached to the rotating disk of the machine.

I'm not a concrete guy, but I believe if you put a thin layer of something across the floor it might not bond well with the current floor. I would think as soon as the integrity of that layer was punctured, you'd eventually see it start popping off, especially if you have heated floors with it expanding/contracting.

If the pitting isn't terrible, I like the idea of grinding across the floor. Of course, you could only do that so many times before you ultimately should consider a rip and replace of the floor.
