Hi Robert .... you can install tile right away with an un-modified thinset mortar.
(NO mastic - NO polymers)

I was correct in applying the Kerdi-Bond seaming tape to all the joints in the shower (wet area). Had I of completely read their instructions (the first time), I'd have been informed of that little detail.
So READ and watch their video when it's introduced to the market sometime in April of this year.

There seems to be a bit of chit-chat about my choice of drain systems for some of my shower pans while using the Kerdi membrane. Let me clear about one thing .... I'm a contractor, not a saleman. I use the system best suited for the work I'm doing and will answer to only one person .... my customer.

I ALWAYS use the Kerdi drain with the Kerdi membrane over wood substrates. There are circumstances when I'll choose to use a conventional drain when building over a basement in combination with the Kerdi membrane. Is it recommended by Schluter? Absolutely not. Is it the right way for my showerpan? It absolutely is.

My advice to anyone with little or no experience wanting to build a shower is to use the complete system as directed by whatever manufacturer they choose to deal with. If you need options, ideas or resolve for whatever problems fall in your way .... you might find the answer here .... and they might not always as recommended by the manufacturer.

Hi Harry, thank you for the info on Kerdi board. Letus know how it all turns out. I am interested in the longevity of the Kerdi board - being fairly 'new'

No problem Robert
If you've seen some of the showers I've built, I use a lot of Wedi board for my walls and ceilings and then the Kerdi membrane and drain for my showerpans. The issues I have with Wedi is that the product rep in my area isn't too concerned about who uses his product or how it's used. Also ... when using Wedi board for a steam room they say go with 1" thick Wedi board but then you still need to use epoxy mortar for the tiles (the rep was nice enough to inform me and my supplier about the epoxy mortar after the job was complete)

Now Kerdi Board takes care of that issue .... it resists vapor, is waterproof and temperaturs resistant.
I'm not sure yet if we still have to insulate walls in steam showers to reduce condensation or if we'd require a thicker board to do that job. But it seems that this board will accomplish more without additional applications of other various products.

For regular showers .... it works great. I just wish there was a way to get out of using Kerdi-Band on the seams in showers.

Could you just prep the joints with Kerdi Fix?
Oh wait, I think you need to take out a 2nd mortgage to buy Kerdi Fix.

Hehe..good one Randall

The price is definately going to be a factor.

If Kerdi Fix is polyurethane, why not just buy polyurethane caulking from the hardware store for $5 instead of $12 from Schluter?

Because, if you wish to have a Schluter warranty you need to use their system.

Fix sells for $26 a tube in my area and it's a special order to boot.

Bob, I used to think that the Kerdi Fix was the same thing as the polyurethane caulking at the lumber yard...apparently it isn't the same...I read a tech sheet about it and the Kerdi FIx is something different.

I wish I could remember what I read! It was a chemical name that only a lab geek would know.
