Abstract
Plaster board panels wherein at least the top layer of one of the two cardboard sheets contains polyolefin fibrides can be easily dehydrated during their manufacture because of the porosity of the cardboard sheets. The finished panels have a substantially sealed surface of low porosity which is resistant to wet treatment and thus suitable for the application of various painting and coating systems.
