On Sat, 27 Nov 2004 12:29:00 GMT, a particular chimpanzee named
"Lobster" randomly hit the keyboard
and produced:

My BCO did insist on skimming as well as two thicknesses of plasterboard...
I'm not saying that she was correct and you're not! but just adding my
experience.

What thickness of p/bd did you use? For 30 minutes fire resistance, a
stud wall needs 2 layers of 12.5mm p/bd. If you've only used 2*9.5mm,
then a good thick skim coat will be needed.
