Not quite sure whether it is plasterboard or laths. Most, if not all,

while. I think it has laths in the loft, but looking at it from
inside the room, I've always been able to see lines which look like
edges of plasterboard.


It's a dodgy P&L ceiling that's been overboarded with PB using long
clouts to hold it on.

Well, the ceiling is still up, 3 days after this happened. Drilled 3
holes where the water marks are, and nothing came out, although it was
noticably soft.

Shame it's not the summer, but I'm sure it'll dry out.

Thanks
