Give him three choices!

 

1-      Budget price, you will grind and polish everything to a marble shine finish, this means the White Thasos will return to a beautiful shine while the border will be grinded, lippage free but they may lose some darkness and shine. 

The granite will not return to its original color but it will have an acceptable consistent color and future maintenance will be a breeze.

 

2-      After #1 offer to enhance the border with a sealer for an extra charge, this will bring out most of its dark color, but gain less shine than full polish

3-      Last option do a complete grind and polish like # 1 and then run all your diamonds and flexing on the borders to the maximum diamonds 8500, but your problem will still be the polishing.  To polish the Black granite you need a granite powder that normally contains some black dies which would ruin the white adjacent marble. So seal the white marble after all diamonds and marble polishing is done,  finish the black with the proper Nero absolute powders , then you repolish the marble floor (especially close the black border) with marble powder. This should clean up your black residue..  Not impossible but you need a lot of time , a lot of being careful and a lot of patience.

Inform the customer, do a test so he can see and let him decide!

I would appreciate your help on a potential job. I’m looking @ a floor in a lobby that has been crystallized in the past. Please see attached pictures. Anyway they want the discoloration on the grout lines removed. Easy enough grind the floor.  Or perhaps someone has another recommendation. The open area is white thassos and it has been ground flat in the past. Now the bordering stone is granite and serpentine which has not been leveled. I don’t feel comfortable grinding those stones especially when are next to a wall. Any suggestions in removing the crystallizer to clean up the grout lines.  Would using straight oxalic acid remove the junk? It will not hurt the granite and I don’t believe it will have any effect on the serpentine. I'll be restoring the white thassos.

The next question should I put is disclaimers in my proposal pertaining  to the possibe condition of the stone once I remove the crystallizer.

Again any recommendations appreciated!
