I've fixed some Aquapanel directly onto a wall like that, and the
problem I found was the rather brittle panels developed stress fractures
anywhere the wall was even slightly out of true. You need the batons
to ensure that the fixing points of the panel are raised away from the
wall, and not causing unfixed areas to bow out and snap.
However, the batons could be very shallow - just a few mm would do.

It's also easier to plane or pack the batons to get a true line if your
wall is wonky, than trying to pack directly behind the aquapanel.

I would agree with fixing the panels at 400mm centres or less; I
noticed the panels would flex at 600mm.


Hmm, as aquapanel is brittle, can you break it after you have tiled on
top of it - for example by tripping and putting your hand out against
it to steady yourself, or banging some heavy object against it?

Hey, cast iron is brittle!

No, providing you've fixed it as per manufacturers instructions it's
very strong; any impact such as you describe would have to be huge, far
greater than needed to cause similar damage to a plasterboard wall. And
if this happened to a tiled plasterboard wall, there would be much more
likelihood of it flexing slightly (with concomitant damage to tile
adhesive/grout, with leaking ensuing) which is why aquapanel is so much
better for showers...!
