Abstract:
1. A method of preparing an epoxy grouted porcelain tile surface, comprising: a) providing an epoxy grouted porcelain tile surface, wherein the epoxy grouted porcelain tile surface further comprises a plurality of porcelain tiles spaced apart by epoxy resin grouting; b) attaching MBG-type diamond grit abrasive media to a polishing disc, wherein the abrasive media are characterized by a relatively coarse grain size; c) attaching the polishing disc to a lightweight polishing machine; d) weighting the polishing machine to enhance the inherent heel; and e) shaving the epoxy grouted porcelain tile surface with the relatively coarse grain size MBG-type diamond grit abrasive media to yield a substantially flat surface; f) replacing the relatively coarse grain size MBG-type diamond grit abrasive media with relatively fine grain size MBG-type diamond grit abrasive; g) shaving the epoxy-matrix terrazzo surface with the relatively fine grain size MBG-type diamond grit abrasive media; h) replacing the relatively fine grain size MBG-type diamond grit abrasive media with relatively coarse grain size RVG-type diamond grit abrasive media; and i) shaving the epoxy-matrix terrazzo surface with the relatively coarse grain size RVG-type diamond grit abrasive media; wherein the relatively coarse grain size RVG-type diamond grit is at least as small as the relatively fine grain size MBG-type diamond grit.
