Hi, I have an issue where the paint is falling from the wall, mainly in about 3 areas of a chimney breast, there is dust on the floor below and in the patches there seems to be some salt crystals.

The House has had a Chemical DPC (I know they are not great) around 6 years ago though the plaster doesn't look damp? but the chimney breast hasn't got any vent which I suspect may be the issue or at least it should have one right?
I was going to install an airbrick and replaster up to around 4ft as the paint seems fine above that. I've even considered blue bricks across the breast if it is damp, though I've never installed any before?
I just wanted some guidance as to whether that is likely the issue?
Other things to note is that whilst the plaster was left bare for over a year I did paint direct onto it with standard paint whereas in most the ground floor I used a contract paint as I know it's thinner though as it was left for so long I thought the plaster would have settled by then.
If there is a more appropriate forum to post this in please advise, I thought this or the plaster one may be able to help.
Thanks for any help
