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!
