Do I need to seal?

[alfietinker]

We've had to do loads of patching/filling on our walls (which are painted), and one wall has been replastered.

Do I need to seal everything with PVA first or just the new plastered wall?

Cheers

You should only need to seal the fresh plaster, but you could get a different colour if you are not using good quality paint.
I would seal or use an emulsion wash on all the walls to be painted.

Thank you very much!

if youve got that much patching then seal it all and let it dry out
