Just went into the lounge and noticed a couple of little rivers coming from a where a fake beam goes into the wall..
its a bit milky coloured - perhaps coconut milk and a little bit sticky.
its progressed about 4 feet down the wall and split into 4 tributaries..
I've just wiped it off - but its puzzling me what it could be!
I moved the bed directly above upstairs and cant see anything. there is a radiator perhaps 3 feet away.
anyone hazard a guess?
