had a phone call today off a customer whos been let down by another plasterer. She said the plasterer has already backed the walls out with lime mortar it just needs the finish. Sooo, first things first ive never even used lime mortars and finishes, secondly is it a lime finish im gonna be lookin for or can u use multi. D you need to control the suction with water or pva etc, do you finish it the same way as gypsum plasters, feel really out me depth on this one as ive never used the stuff before, just dont wanna look like a c**t really
