Board over with water resistant plasterboard or not?

[lbstyling]

Hi all,

I have a plasterer coming in a week to skim over a new extention/bathroom.

The bathroom has insulated plasterboard on the ceiling, but it's not water resistant plasterboard, it's regular plasterboard.

As it's being skimmed, do I need to overboard it in MR plasterboard first, or can I leave it?

I read in the gypsum site that skimming makes MR plasterboard pointless??

Thanks.
