I am ready to waterproof my walk-in shower ready for tiling. The walls are Aquapanel sheets fitted to stud walls, joined with Aquapanel adhesive, and the base is 18mm marine ply screwed to joists. I'm looking at the Mapei shower waterproofing kit from Screwfix.

Got a few questions...

Should I be taping all the joints between the Aquapanel sheets with the Mapei tape?
What do I do about the screws that fix the aqua panel to the wall studs? Some are below the surface, should I fill and/or tape these?
Anything else I need to do or watch out for?
