Hair line cracks in Render/Harle/Roughcast....

[Skyedriver]

Best material to seal these cracks to stop water ingress.
Photo shows worst case, crack is less than 1mm (20p piece or penny won't fit) there are a few others even finer.

Photo has somehow rotated, the crack is vertical.

As a diyer, if just looking to quick fix for winter and no underlying issues, I would look at widening the cracks a bit and then an exterior filler from a respected brand, such as TOUPRELITH F http://www.toupret.co.uk/business-customers/produc...
