Yes, useless title, but that's because I honestly don't know what I'm looking at.
In our new house, there's a wall. It's the dividing wall with our neighbor's house. As far as I know, it's concrete. And it was painted. I'm 100% sure that, when we moved in, it was smooth. And now, there's these things (see pictures, finger for size comparison). They look like blisters, with the paint coming off if you brush it even lightly. OK, so they're not huge, but they're in pretty much the middle of what was an empty, light wall, so they're quite noticeable. I was wondering if it was moisture, but it feels dry, and there's nothing fluid-like nearby - the kitchen's upstairs, but there's no pipes on that side, just the stove and the fridge - and the wall behind those is bone dry. I was worried it might be concrete rot, but that doesn't really look like this from what I've seen. It doesn't smell moldy... Anyone here have a better guess/idea/suggestion about what might be going on with the wall? Just a case of "wrong type of paint for the surface"? Something hideous that'll take thousands of euros to sort-of fix? :/
