Hi John, PVA is a glue commonly referred to as wood glue or white glue. It's often used to coat very absorbent surfaces before applying a finish which would dry too quickly to work on if it were applied direct. For example, when plastering over an artex ceiling, the moisture in the plaster wo.uld be soaked up so quickly that the plaster would dry in minutes, making a smooth finish impossible. Sealing the surface with PVA before you work on it, slows down the moisture absorption long enough for a plasterer to work on the plaster. I hope that helps! Kind regards, Natalie
