Painting over Lime Rendering

[King]

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.

St Astier do lime paints

Yes St.Astier do paints appropriate for lime renders/plasters.

Traditional Dulux emulsions etc may not be appropriate for this finish.

It is important that the right paint is used with lime based products.Your local French Brico should be able to help.

You need to use a finish that will continue to allow the walls to breathe. 

Usually lime rendered buildings would have allowed moisture in the fabric of the house to evaporate easily.

Typically this would have been limewash. Look at sites such as www.mikewye.co.uk and www.oldhousestore.co.uk for futher information.
