Aquaboard joins around bath - seal? Tank?

[TotalNovice-89]

Hi
Our first foray into tiling (other than splash backs/downstairs loo walls). We're doing around a new bath which will have a shower over it. We've used aquaboard for the new walls (false wall for space for wall mounted taps and a recessed shelf and replacement wall where old tiling was removed) but wondering how/if we should seal the joins before we tile? We used aquaboard so we didn't have to tank, but now can't find a straight answer on the joins. Planning on tiling over the whole area.
Thanks!

Aquapanel sell a joint adhesive especially for this.

Brush the edges with wet brush then apply before you fit the board and then scrape off the excess at the joint.

If you have already installed the boards be prepared for a sticky adventure.

Alternative method is their tape and scim.

Also make sure you use the coated screws or they will rust.

No comment on the technique where you use a tanking kit on the joints instead of the adhesive.

All this info is included with the aquapanel or available from knauf.

Take the time you need to make the surface good to make it easier to tile, including the primer.
