In regards to this picture, can someone tell me if this is correct please?

First scape all the loose paper, paint etc off the wall and clean with sugar soap. Then;

1. Tape the joints
2. Fill the low areas and gaps with bonding
3. Paint with 2 coats of PVA; 1st coat 5:1' 2nd coat 3:1 (the wall only, not the plasterboard)
4. PVA again; 3:1
5. When the PVA is tacky, skim the whole wall and plasterboard. 2 coats.

Many thanks.

The sheeted area should be built flush with the existing wall...if thats wooden corner beads next to the gyproc i would take them off before blocking out then taping...pva then again nxt day then 2 coats of multi...just like you said.

Thanks for your reply.

The plasterboard is already in place and sits back from the existing wall by up to 10mm in some places, less in other places, that's why I thought to use bonding to bring it flush.

Is that okay?

Thats right, tape the joins and fill out with bonding then run a straight edge over it to level out with the rest of the wall.
Let the bonding take up and and then skim the lot.

Thanks.

I guess I PVA the new bonding, extg wall but not the plasterboard?

There are wooden beads either side of the gyproc, I can just about chisel some of it out, but not all of it. I guess I can squeeze bonding into the gaps?

No need to pva the bonding if you are skimming the same day.

Plastering over the wooden beads would make the plaster more susceptible to cracking at the joints.

As above, no need to skim bonding if skimming later on but you should PVA that cleaned up wall prior to skimming.
