I just won a job for a travertine shower and floor, as well as a marble floor in seperate bathroom and cleaning soot from some austin stone used in a fireplace setting. She is concerned with a polished travertine floor being too slick when she gets out, so she wants a honed finish. My concern is if I use monkey pads, are they going to cut to much as to expose a bunch of holes if it was a bad batch of travertine? Is there a way to get a honed finish with acid and is consistent, I dont think so? As well, the shower and the entrance to it has calcium carbonate build up. Any idea on how to remove that before I use monkey pads, or will it correct itself with the pads? Please help. Homework is due thursday.
