Thanks in advance, this site has been great especially for Kerdi advice. Well, should have read more before jumping in. As you can see in the pic, I have a tricky situation. I had the thinset too stiff and as you can see it's kind of glommed up on that box corner. It's also a little bumpy underneath. Also, it dried darker than the nice light gray you see elswhere in the pic. My thoughts:
Skim coat proper consistency thinset over the kerdi to make a nice surface for the tile. Is this ok?
I'd hate to try and tear the kerdi out, it is stuck very well on the wall.
As I continue I will sponge the extra thinset off the kerdi, but is is OK to have dried thinset over the kerdi as you can see?
Do I have to tear this all out???? Hope not!
Thanks again for your counsel
