Although we are oriented towards working on stone, I am presently engaged in polishing my concrete garage floor, To begin with, it has a coating of epoxy which, slowly but surely, I am removing with a good stripper,  dwell time, and sharp 4”scraping blades, which I change very often. Once the epoxy is gone, I will start to grind with a floor machine, i.e., 150LB Kleidex.
What I don’t know is what type of diamonds to use with this machine on concrete. What I am looking for is a good source of information on how to proceed in regard to which diamonds to use [which grits, which bonds] If any of you know a source that would be able to inform me, that info would would be greatly appreciated.

Thank you
