How do I prime Promat boards before applying a plaster finish?
All Promat boards tend to have a high suction and therefore it is generally difficult to apply gypsum plaster. Traditionally PVA has been used, apply a number of sealing coats of diluted universal primer/PVA (e.g. 1 part PVA and 5 parts water). Sealing coats should be allowed to dry thoroughly (approximately 24 hours). Then apply a bonding coat (3 p
