How should I install marble over Ditra and Kerdi?

I'm sure this topic has been covered but I've searched for a few hours and can't find what I'm looking for. Please send a link if you have one!

I am ready to install a polished marble floor/shower in my renovated master bath but am concerned that the regular ol' thinset that Schluter recommends over the Kerdi and Ditra won't be sufficient. Am I wrong? In the Kerdi manual, it says to contact Schluter (regarding marble) but I think I can get better "real world" advice from the pros here. Will thinset work or am I looking at an epoxy application (which would void the Schluter warranty)?

The tile is dark brown/black, 3/8" thick, polished and does not have a resin backing. It will be installed on the floor and the shower walls. The company I got it from mostly supplies contractors for commercial buildings and hotels. For what it's worth, they assured me that it is suitable for wet applications.

Thanks,
Ben

Yep, it'll be fine in there, just make sure to seal it!

I would recommend following the Schluter folk's recommendations. They've done the testing and know what they're talking about. Plus, it helps having the warranty on your side.

Just make sure you flat trowel the backs of the tiles and use a white thinset. You'll get a great bond and no dark spotting of the marble.

Ben,

you really need to see and understand how good a "quality" unmodified creamy thinset is.
It will work good.

Thanks for the quick responses. I guess the real question now is if my tile is "green" marble or not. I called Schluter and they said (for a green marble application) to skim coat the Ditra with unmodified to fill the "holes" and lay the tile with 100% epoxy. They do not warranty the epoxy over the Kerdi. I have read that most dark marble (like mine) is considered green. Is there any way to really know for sure?

Check with your tile supplier and ask if there have been any problems reported with your particular tile.

If they don't know and you are in doubt, you can perform a saturation test with a couple of tiles. Check each with a straight-edge, then support the tiles so the face of one and the back of the other are submerged in water for at least 1 day or longer. Check for straight again after 24 hrs of submersion, then again in another 24 hours if you have the time. If they are warped then use the epoxy.

I'll try it. Just so I have it straight--if the tiles do not warp, it's OK to use non-modified thinset for floor and shower in your opinion? I'll let you know how it goes.

Hi Ben, you will be just fine with the unmodified thinset.
