Plastering up a doorway

[Joeylegend]

Hi , i had this advice:

'First, remove the original timber door frame as plaster won’t stick to wood'

thanks

Does this mean the whole inner part as well, I removed the outside skirting and the door batten on the inner frame, then inner frame is very slightly not flush with the existing wall plaster , it is about 3mm in from the existing plaster

Could I get away with just, leave the inner frame and using it as base to fix the batten to in order to stud out the wall?

Good advice.

The “skirting” as you call it is actually the architrave &, yes, you will also have to remove the timber door lining. It should come off fairly easily, remove the door jamb first to check it’s held on with nails & not screws; if it’s nails, just jemmy it away from the wall starting at the bottom.

No, any plaster you out on it will just crack & look awful & will probably fall off. You will need to set the stud back from the face of the wall to allow for the thickness of the plasterboard; exactly how much depends on weather you are just going to skim the boarded up opening or having the whole wall plastered; I would advise re-skimming the whole wall as it’s the only way to guarantee you won’t see the join. You should break the edge of the original plaster away around the door opening to give a jagged edge providing a key for the new plaster & the join must be reinforced or it will almost certainly crack when it dries out.
