I'm using it on this job Kerdi Board shower It builds a shower better than any backer board I've ever used.

Looks like a winner to me.
Are you taping joints with Kerdi Band or Sealant?

Taping with Kerdi band. I used a bit of sealant in one spot, but I'm continuing with the band for the rest of the installation.
It is definately a winner Randall .... it's going to be expensive but it will increase productivity big time. It will become available sometime in April.

Randall ... what do you know about its vapor retardant properties?

As far as I know the vapor properties are the same as Kerdi with the added benefit of some thermal insulation.
As you have seen, the membrane is not actual Kerdi.

The multiple methods for installing the board pretty much cover any job site issues.

Now, if you could use Kerdi fix or HydroBan at some of those corner areas and not have any excess build-ups.

I'll try to see if there is any formal literature at Coverings.

Schluter 2" Kerdi board and Kerdi-Fix.

Pretty strong stuff.

Hi Harry, nice pics of the Kerdi board installation. Have you used Wedi before? If so, how does this compare to Wedi?

Also, would you say this is a lot faster than installing drywall and then covering with Kerdi in the traditional manner? It seems like it must be.

I've used lots of Wedi ... it's a great product. But this new Kerdi Board seems easier to work with, will work in steamrooms and saunas without extra prep and generally seems more diverse in application.
Check the last 3 or 4 photos where I built a box out of Kerdi Board to cover a vent. It took about 6 minutes to complete. Normally I'd have to build a wood frame and then attach my backer which would have taken over 1/2 an hour at least.

I used Kerdi Band in the shower when I probably could have just used the polyurethane caulking. I'm still not sure on a few things yet ... so I kind of over do it a bit to cover my butt.

One of the niches I made for the shower in the photos was too wide. So I added 2 pieces of 2" board bonded with Kerdi Fix and it was perfect in about 3 minutes.

I know it's going to be expensive, but the time I'll save will be a healthy offset.

Thanks, Harry. It will be interesting to see where Kerdi board comes in on the pricing spectrum.

Wedi is $30-35 a sheet here, so I bet Kerdi will be at least in that range.

Harry, how long do you have to wait before installing tile on Kerdi Board?
