Ive never seen a mud bed done over ditra, and have never seen it in any of the Schluter literature. I would think that it would smell like a swamp after getting wet with the water sitting in all those little pockets that cant make it to the drain. With all those little pockets, probably no water would make it to the drain. I cant ever imagine why anyone would put a mud bed over ditra - makes no sense.:rolleyes: Any slope should be under the waterproofing, not over.:no: Really curious here. Anybody else heard of or is doing this?

How do you get the water to the weep holes? Do you use the old system with the liner on the preslope and the clamping drain? Then the Troba mat placed directly on top of the liner with the mud on top? That will drain the slab real fast. I'm thinking maybe you got the names mixed up.

In shower pans we use waterproof membranes in 5 or 6 ft sheets, cut to length.
And we pack a small pre slope (no greater than a 1/4" per foot), then lay the membrane, then pack mud OVER the waterproofing.

So yeah, we float mud slopes over waterproofing in showers all the time.

You can read an article of how we mud shower pans for tile.
And let me know how that fairs with TCA standards.

The above links is fine. It gives a rough overview of how to build a standard shower base. Certainly a novice wouldn't be able to do it solely by those directions. Of course that is not the intent of the article.

I guess you simply misspoke when you suggested Ditra with Kerdi on seams followed by mud base for a shower floor? That of course would be a silly way to do it.

Lee,

Are you talking about Hydroflex for a shower floor or wall, or both? I've never used the product.

I think you meant Kerdi, not Ditra. That is why I said YIKES:eek:
