nail holes in fibre cement slates - do they cause staining??
Posted: Fri Jun 26, 2009 10:58 am
Hello,
Can you tell me if holes drilled in fibre cement slates, for copper nails/crampions will cause staining via the rain washing cement powder down the roof.
In some slates I'm using I've had to drill holes which end up being unused , will these holes cause more cement staining?
Cheers
