Can You Skim Without Pva

The correct mix for pva for plastering is 1 part pva to 5 parts water, and really only used to stop the plaster drying too quickly, plastering over silk paint with or without pva can only be as adhering as the paint before, pva doesnt make the plaster stick to the behind of a painted surface!

Do you wet plasterboard before plastering?

Plaster must be applied when a surface feels tacky, but not too wet, to help it bond to the surface well.

Does plasterboard need skimming before painting?

If you’ve attached plasterboard, or drylining you have the choice of either painting or decorating straight onto the board, or finishing with a layer of skim plaster. The skim tends to be favoured because it provides a superior finish, and it adds an extra layer of sound proofing.
