Paul's kerdi board niche method

[ceramictec]

so on the Kerdi-board the surface fleece isn't waterproof only the Styrofoam whatever it is core body is waterproof ?

so making cuts & folds in the corners open up a possible leak.

* without using the kerdi band.

Brian the orange is still Kerdi just the fleece is for bonding nothing else. The class I was in said that you could score and snap like that and not have to kerdi band.

So if a corner of two pieces of Kerdi board sealed by Kerdi Fix isn't water tight, then how about tile repair on a Kerdi or KB shower?

We were told in Schluter training to do the following for a tile repair:

1. Bust out the tile

2. Apply new piece of Kerdi to area

3. Since it isn't possible to get two inch overlap, use Kerdi Fix for a water tight seal between the new Kerdi and existing Kerdi.

What am I missing?

[Chad Deiter Company]

It is waterproof .

I think John was just referring to the fleece alone not to the ply-ethylene in the middle of the fleece which is waterproof.

[Crestone Tile]

If you look at the picture of his box, the Kerdi Fix is making contact from one piece of membrane to the neighboring piece of membrane ... Kerdi repairs with kerdi fix rely on no more than that much coverage when bonding two pieces together.

why not throw some hydroban in the corners?

[silvercitytile]

was thinking the same

[The Kid]

Because hydroban requires modified thinset.

not to jack your thread paul and make it a schluter thread or any thing but,
how come schluter hasn't come out with a liquid bandaid?


i'm sure they will

So are you saying that unmodified thinset won't stick to hydroban?

or the warranty is void if you don't use modified thinset?

confused:

[Crestone Tile]

Both.

Tonight when the box was drying out for the third time. I could clearly see the orange was wet , all wet areas were located mid -score and snapped area. Tomorrow I plan on putting a wet sponge in the middle of a sheet of k-board to see what happens

I think they call it "Kerdi Fix"? Comes in a caulk tube. I've used it. Good stuff.

I don't think the orange on the board is the same as fabric kerdi. It doesn't exhibit the same waterproofness. If it is the same, its mighty thin and not waterproof. I know for sure if I made the same box out of fabric it would hold water.
