70 metals, I use those thin ones that are used for taking off lippage, the diamonds are on the outside, not buried in the body of the resin. the 120 is not quite aggressive enough. This is also how we take off cure and seal , and sealers from concrete that we are going to stain..We grind alot of concrete, and we do it all wet as well, which i tell people pretty eliminates the dust, which makes us green..We take our slurry home in a bucket, we dont pour in down their drain, just bag it up ...you could also use those flexible copper metal pads that are used for edges, they dont leave much scratches, I use 3 of them under a swing buffer with a satelitte head, which is kind of similar to the klindex head, only its not planetary...thats for the smaller job
