Ok, I took off the high spots and am applying some more leveler over some areas. It is starting to look ok. There are a few spots that could use some sanding though. Can I use normal Aluminum Oxide sandpaper for concrete? What grit? I would try an angle grinder with a masonry disc but that is too fast and inaccurate. Should I use this...

I have been doing some reading and found that on bare concrete something should be used and that Basement Proofer will be great. Hopefully it is not too pricey.
My last question...
Outside of the bathroom is the laundry room and a chunk of old green carpet (maybe 10X10) that I would like to replace with the same tile. The concrete out there should be pretty smooth but it is painted brown. I have read that putting those self adhesive vinyl tiles over painted concrete should work fine and they should stick really well. Is this true or do I need to do something with that too? Thanks
