Hi.  I have a client who has asked if we would remove the gloss from an office lobby floor, leaving the floor with a completely non glossy flat honed finish.  It is a Tennessee marble. We actually did work on a floor in this building a year ago and rendered a low gloss sheen, which came out very well. We cut the floor with diamonds from 50 up to 200 and then used a combination of 5x and honing powder.  In this case I would probably do the same thing and go with just a low grit honing powder.  I also believe this floor was crystallized.  Was wondering if anyone else has had a request like this and has a good approach (what diamonds to finish with, what grit honing powder etc.?)  Thanks so much.
