After removing wallpaper and getting rid of as much wallpaper paste residue as possible I am wondering if any that is left will affect the skimming. Should I seal the walls with something like Zinsser Gardz which is advertised as good for sealing in wallpaper paste?

Hi Thomas,
All I have ever done is applied PVA to the wall - to ensure the new plaster adheres to everything. This has always worked for me.
If you do use any other products - just check it will act as a bonding agent for the new plaster.
