While pigments can work great in certain situations-using them as john says on porous stones could be a mistake. Working small areas and managing the cleanup of slurry in the grout lines is a logiclal action.
If you are going to finish with a color enhancer depending on the product will turn the dark grey limestone almost black I might be less concerned with the absortion of a dye. How dark will the color enhancer turn the stone. Sanded or unsanded grout lines? If sanded maybe you can write something into your contract to protect you. Maybe you can do one diamond cut with least amount of water,clean up,dry using blowers, color enhance and high tail it out of there.(dont forget the check on the way out!!)

My concern with adding dyes to limestone the stone may absorb the dye and cause you more problems than dealing with the grout. You could actually have area in the limestone that could absorb the color and other areas would not absorb any of the color .

I would find a suitable spinflex or twister pad and even then (if you are going to a 400 or less hone) you still run a risk. Pre seal, or pre wet your sections before starting. I would stay away from powders on this one.

Partners,

Next week we will be honing dark gray limestone with black grout lines and I must keep the grout as black as possible. We will finish with color enhancer but I can't tell if that will enhance the grout color to the original black. I was thinking about adding some kind of dye to the honing powder. Is this a good idea? What do you recommend and where can I get it?
