DIY Vapour barrier plasterboard
Stuart Noble wibbled:
Probably not as effective on a porous surface though. IIRC paraffin wax
is the vital ingredient in water resistant PB
Ah - but aren't there two distinct products: vapour barrier *and* moisture
resistant?
The former is useful to me to prevent excessive vapour getting to cold bits
of wood. The latter would be of more use perhaps in a bathroom?
Cheers
