Hi there,

I'm trying to block up an old doorway and plaster over it.

Rather than remove the door itself and fit a stud partition and
plasterboard - could I just screw the door in place, seal the surface
and skim plaster over it?

Would a genorous coat of PVA over the paint finish of the door be a
suficient key for the plaster and would I need to tape over the are
where the door frame meets the existing wall to prevent the plaster
from cracking?

TIA!

Simon
