is the factory kerdi seam water tight??? please explain this more, I'm confused on what you mean.

all seams should be overlapped 2".

Only "factory seam" I'm aware of would be the seams on the pre-fab corners that are available. Those are made of the KerdiBand material.

Like Brian, I'm confused on what you might mean here. :scratch:

Sometimes you get a roll of Kerdi that has a seam in it... It's only overlapped about 1/2", but I have a feeling the two pieces are fused with heat... I havent used a piece like that on a shower floor, but have on the walls without any fear.

you are right splinter.sorry gang for not explainning it better but it is a factory 1/2 seam that came in the roll and i installed it on the wall.i cut a small piece of it off and tryed pulling it apart and i was difficult and when it came apart it took the material with it.hey splinter i think i might have seen your call sign (splinter) on a difrent bulliten board? also could some one please let me know if the foam curb with mud bed is a good combination and has any one done that.thanks ...dan

Hey Dan,

Yeah, I've been stirring up trouble with the plumbers over on a contractor forum... It's not quite as friendly and open-minded as this place.

I've never used a Kerdi-curb or pan, so I cant help you there. Sorry.... :)

The Kerdi curb works great, Dan. I don't think I'll ever go back to building them the old way. Less than 5 minutes and you're done.

Some people have complained about it's width, i.e., being too wide at 4.5". I think it's fine.
