Are you doing multipurpose white thinset ,or epoxy?
I typically on small numbers use latacrete epoxy thinset,and always over 23 years of custom marble installations,use epoxy grout, I can set in epoxy and grout the same day, grind the next day
If thin set, I would wait a minimum 3 days on thinset,and 2 days on Portland grout, to avoid moisture issues

First question is: after installing and regrouting, how long should we wait before honing and polishing the rest of the floor. Second question: just one of the tiles needs to be cut down. I don't have a wet sander and was wondering if this is easy enough to do with an angle grinder and diamond blade on site   If so, what type of blade to use.  Thanks for any advice.
