Plastering Advice...

Two coats of multi-finish should be fine - I wouldn't bother with anything underneath.

I'd probably pva the whole lot - especially if there are still bits of paper stuck on. It will help to stick them down and prevent them from getting on your trowel and causing tracks in your skim. Also, if you've damaged the paper on the plasterboard while stripping the wallpaper it will help seal them.

Nice to think I was on the right track...!

Its not the planning that's the hard bit ;)

I'd go along with all the above, except that I'd have thought that a single coat of multifinish should really be all you need.

Mind you, if your plastering skill's as good as mine.....! :-)

I usually go into the job anticipating two and then if it looks good after the first I leave it a bit and then polish up.

I also find it pretty hard to get a really good finish on plasterboard, but pretty easy when applying a second coat to a still tacky first coat.

Barsteward when someone just wallpapers over plasterboard innit. ;-(

If you have the ability to lay it on thick,this is all you need.

Don't forget the scrim and make sure the room is cool.

I'd use 2 coats of PVA. The first allowed to dry to seal the lose bits of stuff then the plaster is applied to the 2nd PVA coat while its still tacky.
