Does any other plasterer suffer with these , ive been plastering for more years than i care to remember ,to a high standard , but recently ive been getting these lines in my setting , like drag marks , cant trowel them out . when its painted you can still see them , faintly , its doing my nut in , tried all diferent mixes , wet stiff etc , sanded and polished trowel but they still keep coming back from time to time , mostly , strangely enough nearer the bottom of the wall , any thoughts would be much appreciated
