Water test drop
I had water drop something between 1/16 and 1/8 inch over 12 hours but is holding steady now. I left a box fan on overnight, not sure if wicking and evaporation caused it. It held the same for 24 hours so I added water to hit the original line and it has been holding for 8 hours.

Do you think it's just evaporation and wicking, or the corner joint allowing moisture through? Maybe also hydroban? I have been googling all day and signed up on the forum to ask.
Hers is a bit more on the curb wrap, just want to make sure I can set tile on it or if I need to revise.

Hey Brian- Nice to see you on here. I'm thinking that it was a combination of the evaporation from the fan and also the thinset on the pan that drank up some of the water. There is a large patch of thinset you used to flush up to the drain and I bet that is where a lot of the water got absorbed.
As long as each seam has a 2" overlap, it doesn't matter what order you do it in. Hope that helps!
