Hello,

I've got a damp patch, half way up an internal wall. It's only small - maybe
6 inches by 4 inches.
On the other side of the wall, I also have a small damp patch in a similar
position.
If I paint it, it just bubbles up. What is the best way of treating this?
No idea why it is appearing in this particular position - I am in an old
Victorian two up two down, and this wall was originally the external wall,
before the extension was built for the kitchen / bathroom.

cheers for any help.
