KerdiBoard issue

I am currently working on an exterior fountain for a client. I've installed 2" KerdiBoard across the back corner to house the pump and hoses. The issue that I'm having is the membrane has separated from the core in two places. It's a little concerning!

Have any of you run into anything like this? Any ideas?

I ended up cutting a slit in the separated area and "Kerdifixing" the flaps back down. Will this be the solution? Will the entire face of this thing separate?

Man, I'll bet Schluter will be all over that. In my purchases and at our local distributor I've never seen any delamination yet. Once JB weighs in we'll all see what the fix should be. Also let us know what Schuter says too. Call your rep - likely Dan Curtis 707-888-8531

I had something similar but found out it was my own doing. I used KB to do my countertops and before I installed the tiles we used them for a week or so. Ended up cooking breakfast using a large griddle. Afterwards under the griddle there was a bubble - delaminated area probably 5-6" across by 3-4". I ended up slicing it open - kerdi fixing it back down. Tops have been in for couple of months now with no problems.

I also believe that Schluter doesn't want the board in direct sunlight such as for an outdoor kitchen.

Did you subject the board to any type of heat?

Had the same thing happen to me on some pcs that were sitting on my trailer. Turns out that this is an issue when the board is exposed to direct sunlight or so I have been told by Schluter.

I looked thru my Kerdi -Board literature and there is a disclaimer from Schluter that says the board must not be stored outdoors where it is exposed to direct sunlight or weather.

That would indicate to me that the product is not rated for exterior use, but I could be wrong.

i dont think once the kerdiboard is covered with tile it would matter if it was outside.
just not outside uncovered.

Talk about customer service - I called Schluter Rep to tell him about the above situation. He got a hold of Tile Dale and sounds like that issue is licked. I'll wait to see what Dale has to say, but it was nice of Dan (Schluter Rep) to dive in, handle it, and then even let me know the current status.

Fine Customer Service. Thats what I build my business on and I LOVE to see it in other companies - My favorites:

Laticrete
Schluter
TLS (Mick)
Master Wholesale/RPM Mats (Seattle)

REI - Recreational Equipment Inc.
Nordstrom
FedEx
and the list goes on.

Thanks for your great service - Merry Christmas

Yes, Dan called me back right away and assured me that my fix was good. He said that it'll be fine.

That's great. But WHY did it happen in the first place?

He said that it was an early version board with uv sensitive adhesive. He said "Cover it up"

hmmm...

Well until I know exactly what causes this and how it has been fixed and am convinced it has been fixed and not just switch glues and see what happens next kinda fixed..i aint using the product..point blank.

I mean whats it going to do over extended time? How do we know plasticizer migration/shrinkage does not contribute to this problem? Or how do we know this glue is plasticizer resistant enough to handle oils leaving the cpe. How do we know the new glue is good enough?

Im not going thru the tile over mastic and green drywall stuff again..or the moldy hardie board BS again. Call me a pessimist but Ive seen so many products turn out to be crap in the last thirty years i am not going to believe any manufacturer by blind faith..I don't care if it has a 200 yr warranty.

Having some mystery glue go bad and switching to some other mystery glue..just does not cut it or give me any confidence in this product..and unless I feel good about it..im not using it in someone else house...sorry but im not taking any chances

If a product reacts this way , there is no way you can repair it right.
Removal of the product is called for. There is very little chance , especially in your application , for a long lasting installation.
