Hi chaps. Iv just secured all the paster and moisture board to the solid walls in my bathroom to give a clean flat surface to tile on. Im reading that i now need to prime these walls using a good primer such as BAL APD, is this correct? Im also reading posts which say to 'tank' over the joints. What the dickens does this mean??? Regards Jonny
tanking just means either a, a waterproof membrane or b, a waterproof liquid applied by brush to stop any ingress of water,
