I have a stud wall that has finished depth of pretty much spot on 100mm
I have planed timber door lining that is about 108mm

is 4mm on each side too much to ask of skimcoat?

should i be thinking of getting 2-3mm off the door lining timber or is there smarter ways to do this?

4mm is good if you intend 2 coating it.

iv never plastered before so it could be in my favour to have two coats.... sort of a take two approach after learning on the first coat. is it ok to do two coats with standard plaster...not some other 'bonding' plaster like i think i saw somewhere

Sorry can you please clarify?

1) no bonding coat= do not use a bonding coat?
or
2) no, bonding coat=as in i SHOULD use bonding coat?

if 2) what is bonding coat? is it different stuff altogether or just a different mix ratio of normal plaster or somthing?

area quite small, see picture. Both sides of the wall you see to left of opening

you won’t need a bonding coat.
bonding coat is an undercoat/backing plaster for filling out much deeper than 4mm .
4mm is nothing , you could do it in 1 coat with multifinish , but your result will be neater with 2.

@bennymultifinish when you say multifinish for you mean multipurpose joint compound?

I have plasterboard (Gyproc) and the joints taped using joint compound! do i use joint compound for the skimcoat? I had bought gyproc skimcoat for the skimcoat but i was told somewhere that this should not be used over standard joint compound?

help?

I thought you intended skimming it?
if you intend skimming it with multifinish your joints should be scrim taped.

in summary, i have taped corners with paper tape and joint compound already. What do i skim with?
