Spot setting is for hacks - so is drywall in the shower
So - if a Schluter foam tray is not installed PERFECTLY LEVEL with the EXACT RIGHT AMOUNT OF THIN-SET then it's a TEAR OUT.
Thank you Mr. Kerdi shower pan.
I guess you folks on John Bridge's forum only answer the tough questions when some Troll on Terry Forum's calls you out or brings attention to your lack of knowledge. Jim you also defended John Bridge here not to long ago when I called him a hack for "Spot Setting Tile" - what a washed up sell out hack he is.
Then you said it's OK and the TCNA recommends its. You forgot to mention the part of epoxy thin set mortar only and the part about exterior walls....
Selective wording - all in a salesman's day.
Drywall is for hacks.
Spot setting is for hacks.
This is the real story here.
Failing Kerdi Shower with Drywall and Spot Set Tile
How about this one Dana?

Pretty sure it's a drywall issue or spot setting tile failure.
Yes Dana - that's a Kerdi Drain shown in the picture. How can this happen? I thought Jim said Kerdi Showers dry out between uses... Oh ya... if every step is installed "PERFECTLY"....
"I was reading through John's book, and he mentioned spot setting stone. Is all the stone or larger tiles set this way, or just the first few to get a true flat plane?" - Scottish Tile and Stone 2/1/2006 Source John Bridge Tile Forum
Maybe the wall is wicking the moisture up the wall? Maybe the person just followed John Bridge's advice and spot set the first few rows of tile to get a true flat plane? Hmmm. I wonder
Lets not forget this Kerdi Board Failure Dana....
Water resistant Dry Wall.... That's all you need right?
Dry Wall and Kerdi Board - both bad choices for a shower
Jim Check out my results from my Kerdi Board Shower Niche Flood Test.
The niche started leaking on Day Four of the testing. Not a good showing....
I'm so glad I coated the two Kerdi Board niches I installed with Ardex 8+9....
Dana does that count as a Kerdi Failure? Or are you classing Kerdi Board in a separate category?
Drywall gets the thumbs down from TileLetter.com
More experts from TileLetter.com give drywall the thumbs down for your shower.
Just Jim and Schluter like this specification..... One in the same I think - Jim and Schluter
John Bridge on why to use drywall in your shower build.
"Of all tile substrates, drywall is the most readily-available, least expensive and easiest to work with. When building a new home or renovating an old one, the installation of drywall does not need to stop at the shower area to apply a different product, which may have a different method or require special knowledge to install. Quite often, the installation of CBU or specialty backerboard units is not done properly; removal and proper re-installation have to take place before tile is applied." - Quote by John Bridge
Well that sums it up.
* Drywall is the most readily available product.... hmmm I see cement board at every single building store I shop at.
* Drywall is least expensive.... True it's the cheapest product out there. That I agree with.
* Drywall is the easiest to work with.... Dam true again. This is important - the job of building your shower should be easier for the people. That's what you want. Easy - not better.
* Drywall can run right into the shower... Again so easy for the drywall installer.
* If the CBU is not properly installed it needs to be redone.... Same would be true for drywall I think here.
Well I guess I know who trained Jim here. John Bridge certainly knows a lot about making the job easy. I guess as an aging tile man years back cement board was to hard for the frail old guy to cut and carry.
Lets look at cement backer boards. They do not grow mild like drywall.
They install like drywall.
Cut like drywall.
Out perform Drywall.
You decide. Make the job easy for the crew and use the cheapest product or build a shower that is premium. tough choice.
Yum Yum yum - mood growing on drywall....
You can even use drywall for your shower's curb. Just ask Jim how. The secret is you need something orange over top.

Drywall and a Failing Kerdi Shower
So Dana - Jim
Whats your take on that failing Kerdi Shower with the water stains below in the picture (I did post it right after you asked for one Dana). Both you men seam to skip past that photo.
Here it is again.
That's a full Kerdi Shower. With Marble. It's Failing - unless water stains are acceptable by your men's standards.
Do you think it was maybe "Spot Setting"
Dana you ask for any pictures and I gave you a few to look at. Your last post makes no sense. Please help us understand why this Kerdi Shower is failing.
I wonder if this is why spot setting tile is not allowed.
I would call that a failing Kerdi Shower Jim. Look it's a Kerdi Drain. And Iwas told Kerdi on the shower floor and walls.
Jim did you not say a Kerdi Shower dries out between every use?
That looks wet to me. Could it be - just possibly - a slim chance that the tile setter spot set the lower courses of tile? Maybe watered down the grout a little to make it easier to work with. Could those be possibilities Jim or are we to believe the fault is in entirely the marble's - in that one exact spot. Spread over part tiles like that.....
I wonder if this is why spot setting tile is not allowed. I wonder if this is part of the reason I call John Bridge out as being a tile hack?
Here it is again.
Jim lets here from your Boss Dana. Dana what do you think the problem is with this failing Kerdi Shower?
I think the Kerdi was not installed properly maybe and is wicking water into the drywall. I think mild is growing on this shower right now. I think the install would have been perfect if spot setting tile was not done. I would bet that when tapped those tiles and all the wall tile sounds hollow in over 30% of the wall.
Installer Error of Course People. This is no fault of the Kerdi membrane and all do to how the Kerdi and tile where installed.... If only there was a way that you could keep your ten year warranty and have extra piece of mind..... think.....think... there must be some way.... ohhh. ya!!! I remember
