About to start tiling.... Prep advice needed

[markyyyyyy]

Hi everyone,

I am putting my Moisture resistant plasterboard up tomorrow via dot and dab.
The wall is next to the bath and shower.

I am going to be tiling onto this plasterboard one the adhesive has dried

I have a few questions:

1. What preparation does the MRboard need before tiling?
2. What adhesive is best use on the board? (bare in mind it's for bathroom)
3. As I am using D&D for plasterboard, should I drill into the dried adhesive for support? If so, what screws are best for this?

For further info, we are tiling the whole bathroom

Many thanks for your help, in advance
