Could you or would you go over the surface of a coarse grain riven sandstone to smooth it off - not try to grind it flat and make it smooth but make it a bit smoother than it currently is. If the answer to that is 'yes you could' which diamond pad has the most coarse starting pad?
Got a job enquiry where a slab wants replacing and now most of the screed that was on the surface has now been removed they want it slighly smoother
