Can I use 9mm plasterboard on walls?

No The 9.5mm is normally for walls. You will need your studs or joists at much closer centres for 9mm board. On new homes we use 15mm for ceilings as you can get away with 600mm centres and no noggins are required. Although it is heavier and more expensive I would always use 12.5mm board over 9.5mm.

Should plasterboard be skimmed?

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.

Do you need to PVA new plasterboard before skimming?

The plasterboard does not need to have any PVA applied – you are fine to just apply the plaster direct. Yes normally it is nice to apply the skim coat, to a backing coat the next day – however it may still need sealing with PVA or soaking down with water.
