Tile bathroom and shower enclosure

[Ralph B]

Been asked to quote for tiling a newly built bathroom with shower enclosure within a single storey office building. On inspection found a mixture of plywood and moisture resistant plasterboard being used in the shower enclosure where there were black mould spores on the plywood. Moisture resistant plasterboard throughout the bathroom and shower enclosure had areas showing damp, some with water droplets on.

Propose to tank shower enclosure using BAL WP1 tanking kit and use BAL single part flexible adhesive. How should I combat the mould prior to tanking? I will use microban grout.

How long should the damp plasterboard (dot and dabbed to block wall) be allowed to dry before tiling?

Is there any chance there'll change the ply, if it's got mould growing on it allready that could creep thru to the grout.

I'm going to ask but suspect due to a tight schedule for occupation this will be declined. Thanks for replying.
