Ardex does a great job holding tile to the wall allowing the installer time to level and adjust tiles without fighting to hold them in place on a vertical surface.

Can’t even handle 12x24 tiles on the ceiling. I back butter my tiles. I broke 3 tiles because of this expensive stuff. The schluter all set held fine and it’s not even a large format thin set. I might try pro lite instead.
