I'm currently planning a wet room in an extension which was built a year ago. 3 of the 4 walls are thermalite with Hardwall but no finish plaster. The hard wall is very flat and keyed as my builder knew I planned to board out the room (it's also very dry as it's had a year to go off).

My question is what https://www.tilersforums.com/forums/tile-adhesive/ to use to bond Wendi boards to it since cement should be avoided with gypsum?

The boards will be mechanically fixed as well at centres appropriate to the tile weight I end up choosing...

Why a non-cement https://www.tilersforums.com/forums/tile-adhesive/? I use any old decent cement https://www.tilersforums.com/forums/tile-adhesive/ and back up with fixings afterwards.
Kerdi-board would be ok with gypsum https://www.tilersforums.com/forums/tile-adhesive/ - no cement.

I'm not even 100% that the cement face on Wedi is hydrated, so definitely not suitable for gypsum https://www.tilersforums.com/forums/tile-adhesive/. I believe it is sprayed in some weird technique. Can't quite remember where I heard that though...!

It's not so much about the cement in the Wedi board (it's polymer modified) but the the Hardwall (Gypsum) I want to stick them to.

In a normal plaster finished room, I'd use flexible cement based tile https://www.tilersforums.com/forums/tile-adhesive/ to stick the boards up, but everyone I ask says cement based https://www.tilersforums.com/forums/tile-adhesive/ onto Hardwall is a no no... (just like tile straight to Hardwall is a no no...

Any non-cement adhesives that people have experience with?

If the gypsum is well primed then cementitious https://www.tilersforums.com/forums/tile-adhesive/ is fine
