Home was built in New England in the early 1960's. Since we've purchased the house (6 or 7 years now) there was spots chipped off the ceiling in main bedroom above the bed. I didn't think much of it initially. We also have some amber/brown colored drips on the walls in the bathroom and just outside of it, which I remember reading was due to humidity and something leaching out of the paint. Over the years however a few more spots have shown up, usually with this amber or golden brown colored
Well just this year one of our spare bedrooms down the hall seems to have a small paint chip, but half (literally) of the ceiling covered in thee brown colored dots and I'm worried about what they are. The color wipes off if I rub them with my finger tip, sometimes the paint beneath looks like there is a small crack but not always. We've had a small amount of mold on the bathroom ceiling a year or two ago and it looked black, not this brown color.
When there are chips sometimes it chips right to drywall, this chip is about the size of a US quarter or two. You can see some slight discoloration around the chip.
...other times it seems like the paint flakes off to reveal a layer of white beneath it (this chip is about the size of 1 US nickle)
That last picture is giving me hope that this is some kind of paint quality / degradation and not something more sinister. We had an ice dam a few years ago and the water damage does not resemble this, it looks more like, well, a dirty wet spot was above the ceiling.
Does anyone know what it could be and if so, how to remedy it?
