om...
I have plasterboarded my ceiling with the 4 or 5 mm stuff. It is
screwed onto battons I had attached to the existing ceiling. It is
fine in most places, however at its worst parts you can push it in and
it bends in. Will I need to redo the whole thing with the thicker
plasterboard? Or will the skim coat a plasterer will apply be OK? The
ceiling is fairly high and in a bedroom so I dont expect many people
to be pushing and prodding it.

Thanks in advance

James


Wow !!! 4 or 5 mm thick ? You've been duped. That's not plaster board,
it's thick wall paper. The most common today is 12 mm thick, and for a
ceiling to be fire retardant if it has a dwelling above, it needs two layers
of the stuff.

Why did you put battens across the joists ? The plaster board would have
been easier fixed to the joists themselves with noggins (dwangs) put in
between the joists at the ends of board.

Sorry to say but, to me it sounds as though it is all wrong and needs doing
again properly.
