The external walls on our house are Lime Rendered and over the years have gone a grubby grey colour. I want to smarten the walls by painting them. I was advised by a professional UK painter to purchase Dulux Weathershield as this would allow trhe walls to breathe. I've purchased the paint and now an architect friend in France has stated that I shouldn't use Weathershield on LIme Rendering. An emailled request for advice to Dulux bought nothing back in return. Has anyone painted their external walls with Weathershiled or similar ? All help gratefully received.
The exterior walls on our house are all lime rendered and are now a grungy grey colour. I want to tidy the walls up and was advised by a professional painter in the UK to purchase Dulux Weathershield as this would go on fine and still allow the walls to 'breathe'. So this is what I have done. However,an architect friend in France is cautioning me against using the Weathershield. I sent an email to Dulux but received no response - so can anyone offer any help please. Anyone used this, or similar paint, on their exterior walls?
