Door casing and correct fitting

[mordzy]

Hi. I have a door casing to fit into some stud work. The stud work is 4x2 (38x89) the door case is slightly deeper 108mm so I have about 9.5mm proud either side of the Studwork. Is this correct or should it be fit flush one side ?

Is the wall going to be plaster boarded?

Hi john. Yes it is

Then I think you will find that the plasterboard brings the finished wall flush, or nearly so, with the edge of the door lining.

So you just need to tack on an architrave to hide the join before painting the woodwork.

You may need to use a bit of filler or caulk if they are noticably out of level. If you can put it behind the architrave it will not show.

Your lining is too narrow, you need 15mm either side, 12mm for plasterboard the rest for skim.

Whilst I'm in agreement with Foxhole I will point out that it is possible to set the casing to be correct on one side (always the hinge side, and in your case 15mm proud of the studwork as he suggests) then to build up the other side of the casing with planed softwood lathing to the correct thickness (circa 18mm step back by 10mm to form a rebate then apply the architrave, again set- back by 10mm)
