Ceilings will all move eventually I presume and cracks might continue
to open?

What I'm observing is the hairline isn;t getting any wider, just longer as
the stress concentrated at the end works its way along. On the assumption
that the PB is stagger jointed, hopefully the longest crack will stop
somewhere. Can't tell from above - all my celings have 2 layers of 9-ish mm
PB.

Would the flexible decorators caulk be a better option to
allow for movement for quite a while?

They are very fine (literally hairline - you can only see the minor one by
lamplight, not in the day.

Something more liquid came to my mind that would work its way in. How gooey
is caulk? I've never used it.


You have to be careful that your filling doesn't make things worse by
drawing attention to the change of texture and highlighting the filled
area. Been there etc. On a hairline crack anything other than more
Dulux is likely to do just that. I think I might lightly wipe the paint
across the crack with a washing up type sponge. Then again, I might just
do bugger all :-)
