What would be the best way to apply a charcoal black colorant alongside sealed slate tiles?

January 19, 2015
I have recently installed a slate tile floor, and the grout used was charcoal, after the grout dried it had a white haze and discoloration in the grout joints. We have decided to give this product (renew) a shot, but am concerned that the black pigment might stain the slate tiles, even though i have applied 2 coats of sealer on them already. Please let me know what you think!!
Thanks a bunch!
