Adding moisture board to walls for tiling

That’s common in the paramount walls. Cut out 3 channels left to right from the cardboard cells. Evenly spaced top to bottom. Fit noggins. Fit plasterboard.

The walls where the facing board has been removed and you only have the cardboard you have no choice but to stick in CLS and board.

The other walls, assuming they are complete, I would prime the existing board and then dot and dab new board over the top with vertical continuous strips at 300 centres and again horizontally at the top, bottom and mid point.
When adhesive has set fix to the perimeter timber with screws and washers.

If you are tanking the wet area I would save the money on M/R board and buy standard board that will free up some funds for the CLS on the other walls.

The wall with just the cardboard showing has gone. This wall I studded out as I needed to put a shower valve in there and reposition the door.

Sorry, I started a conversation with you by accident. It was meant to be in here
