Mapei Primer to curb mildew

    I have had the bathroom boarded for tiling but the rest of the house is recently plastered and drying so the moisture is moving to the porous exposed boards in the bathroom, I’m getting light mildew around the window and some on the walls which I keep cleaning with a mildew cleaner but my question is:

    Would I be better priming now with Mapei G due to it being less pourous, idea being to seal and safeguard the boards or is it better to wait? As I can’t tile for another couple of weeks due to supplies.

    Also is Mapei Primer better neat on bare plasterboard?

    thanks in advance
