Well, that's good to know. I have a granite that has greyish & black & white bits in it, so it's not the beautiful black stuff! Will be laying over the Ditra (ditra is already down) this weekend. Wish me luck.
I know they recommend sealing it before grouting it - but I better make sure I can seal it.
