First thing u would need to do is power wash walls take off any loose plaster then scud with sand and cement scratch coat and finish coat. For scudding it would have to be mixed at 1 to 1 with no plasticiser l Scratch coat would be mixed at 3 to 1 with wateprofer. Finish coat mixed at 5 to 1 with plastiser

Buffalo billy has it well covered . The only thing I would add is a couple of shovels of lime in the mix for the finish coat
