Two ways to help eliminate the grout line turning lighter,
1.
Be sure to do a good flush on the grout lines with water after
you hone each section.
2.
When polishing be sure to do a good flush with a neutral cleaner
and water , these process will help control the color changes.
If the grout does lighten you can always dye the black grout
using a black leather dye. Apply on the grout line and allow to penetrate then
wipe off with a clean dry towel.
Caution, do not allow the dye to set too long.
Note if you are polishing a black floor with black grout you can
actually add black concrete dye ( powder form ) to your 5X polishing
powder. Caution do not add to much dye a little goes a LONG way

One thing to consider if the grout is black. You might
want to let them know the the grout lines can lighten when powder polishing.
Does not always happen but it can !
Going
to polish a small office of a friend that has black and white
marble 12X12 checker pattern, any advice would very appreciated. Thank
you Stephen
