Plasterboard or plaster

[NBW]

Hi all
One for the plasterer's.

This wall was left by the builders and they mentioned the plasterer will plaster over this with bond to build out before plastering.

2 things.
There is a crack in the wall and there is a gap in the ceiling.

Am I best to plasterboard the wall before plastering?

I’d want some expanded metal across that crack before skimming it. Needs hacking off about 10” either side of the crack and making good first. Screws and washers to hold the mesh, then dot and dab compound laid over that as a binder. 
 

Up top just needs to be dubbed out a bit with dot & dab before skimming over. 
 

Use 75/25% PVA/water mix as a primer on dry masonry to get a good bond. Brush off loose stuff first obvs.

Thanks for replying. 

Is that ceiling gap between the wall ok to be plastered?  Or should it be smaller. 

That's why I was considering dot and dabbing plasterboard to the whole wall

 

Thanks

A decent plasterer will be able to scrim tape that joint and push a decent bit of wet plaster in there on the first of two sets.

 

Are you skimming the whole room afresh? Including the ceiling?

Yeah. I will get a plasterer in to plaster the whole room and ceiling.

Good. You’ll have scrim tape from that wall > ceiling junction, so they’ll fill that up no probs and the tape will stop it breaking / cracking.
