Got up the steps to patch some lifted wallpaper on a ceiling and found
that it had lifted due the ceiling having dropped a bit. I am
suspecting that someone had put weight on the L & P at some time - or
the nibs of plaster have just failed over time.

I am wondering if there is a fix - such as generous squirts of No More
Nails from above and then propping the sagged ceiling back up to the
laths
- or do I have to accept it is a lost cause and rip it all down (ugh
the though of the mess in the new bathroom!!) The insulation is that
blown in recycled newspaper stuff which would all need moving.

================================
Prop the sagging bit from below. Clean the affected area thoroughly
(top) with a vacuum cleaner. Make a sloppy mix of plasterboard bonding
plaster (or 'One coat' plaster) and spread in a layer about 1" thick
working it into the broken nibs. Make sure you wet well the area before
applying the wet mix. This usually works quite well for small areas.

Sounds good - or rather what I was hoping to hear. I don't like the idea
of adding a layer of plasterboard as the sagged bit will stress the
plasterboard (won't it?)

===============================
The other posters mean plasterboarding the *whole* ceiling. This is a
standard treatment for a sick lath and plaster ceiling and is a very
satisfactory solution. It won't be stressed by the old ceiling.

You may have to do this if my suggested repair method doesn't cure your
problem. If this becomes necessary you'll be grateful that you don't have
to remove the old stuff which is about as messy a job as you can get.
