we run terminator pads. the five step pads and have no problems. if this helps we found that in really hard granite we have the swirl marks but to get rid of them after we run both grinding cups we put on the 400 pad from the four step roll, we call it a top or bottom ease, andv run that before we run the regular polish five step pads and that gets all the swirls out. if that doesn’t work try not running the grinding cups if you do not have to. we did it on carrera marble with the grinding cups and it left marks but when you skip the grind tools and go straight to the polish tools it comes out just fine. the closest to concrete color we have ran is lagos blue but had no problems
