Sand & cement or insulated plaster board?
I have condensation mould on my outer walls of a 1st floor flat. I also have a leak from the roof that has blown all my plaster.
Im fixing the roof issue.. but now I'm left with a decision and i have no idea which is best

You use a tight coat of water proof render or a tanking slurry to hold back any damp that is in the walls,then you can thermal board the walls, dot and dab method rather than battens as it will be cheaper and quicker.

old methodologies die out for a reason
remove plaster use tanking membrane and replaster
1. it stops damp permanently
2. it reduces condensation as the membrane has insulative properties
