Hi,
I am about to start my first Kerdi project.
Couple of questions. First, the Kerdi shower valve seal.
My shower valves have check stops on either side of the valve.
So the Kerdi valve seal isn't going to fit around my shower valves. I assume I can just run my Kerdi membrane around my shower valve and rely on the gasket or a silicone ring around the shower valve face plate to keep water out?
Second, I wonder if layering Kerdi from bottom to top is acceptable, or even preferred? In typical Kerdi instructions, I see that the Kerdi band applied in corners is applied after the walls and pan.
Consider the bottom corner between the shower wall and pan. If you applied Kerdi membrane on the pan, then Kerdi band on the pan/wall corners, then Kerdi inside corners, and then Kerdi membrane on the shower walls, your Kerdi system would be layered so that water would never hit thinset on an upslope. Every transition would be Kerdi to Kerdi to the drain whereas the typical installation method would leave a thinset "lip" at the wall corner where the Kerdi band starts. Any thoughts?
Thanks.
