Inside window board / sills

[Barnboy]

I dont know if this should be in here or the plastering topic so sorry if I'm in the wrong group.

My plasterer wants my oak window sills fitted before plastering but I'm not sure if where they protrude into the room, as shown in my dodgy photo,

(photo is of someone else's house that I took measurments from ) should I butt the ears up to the plasterboard or notch the plasterboard so that the sill board ears slip in the recess made and slide back to the stud work ?

I cut the plasterboard so the window boards “ears” were back to the block behind the plasterboard,

 

Slide the board in to the plasterboard, draw round the ears then cut with a multitool

If it’s oak. YOU need to tape them up thoroughly don’t leave the plasterer to do it, pink plaster in the grain is impossible to remove, or get a coat of whatever you are putting on the oak, then tape them.

Or cover the wood entirely with plastic & tape. Also don't let anything metal near them - they'll get black patches v fast.

 

Actually, I might be inclined to fit them after the plastering and then seal around them after.

I will be priming the underside and non visible edges and oiling/waxing the outward faces. 

The plasterer has shown me his own house with the same oak and he's done a beautiful job plastering around them. Hopefully he does the same to mine.

Yeah some plasterers can take care.

I was lucky too,  my plasterer is old school he does things properly.
