Looks like one dirty travertine floor-clean using your favorite high alkaline cleaner, floor machine,brush and extractor.Use diamonds if needed but restaurants want cheap mostly so we would probably run the floor machine in front of the extractor using 280 grit honing powder or a coarse norton pad using a grout brush to agitate and clean the grout lines as we go.One pass over the floor then dry,seal with your favorite color enhancer or impregnator and call it a day. I would test those darker borders and make sure the abrasives you use dont lighten them. I might consider just cleaning those border area with a brush so you dont waste anytime on them unless they are adraded and need refinishing. maybe just hit the borders lightly with a polishing compound to highlight them a bit like mike suggested.

Klenztone works fantastic on oily surfaces and will lift the grime out of the joints. You can use a 5X lightly with a Tampico brush for the finishing.

Subject: [sccpartners] Servicing Limestone Floor

I have been asked to service a limestone floor for a commercial restaurant. Please see attached pictures. They want the grout lines cleaned, etch marks removed and slight gloss to floor. I was thinking about using 800 honing powders followed by use of a spinner. Any suggestions would be appreciated.

Thanks,
