Large sections of my bedroom wall (external) had blown plaster. I think that it’s a case of many years of non breathable paint and a modern skim coat had basically suffocated the wall. It’s a lime pointed solid wall, with internal lime render.
Peter9791
Also, does that brick look like it’s in good shape ? Or does it need anything done ?
Peter9791
Doesn’t feel damp, it’s dry to the touch. That’s what was left after breaking off the lime render. I just have to clean off the residue. I could be wrong but the house is 122 years old with solid wall so I am guessing that would be lime rendered to keep it breathable.
Peter9791
Also JohnD you might be able to see some of the Lime render still left beneath the plaster in the top right, and on the party wall to the left. Perhaps this is a coating of sand behind ? Thanks
Peter9791
I don’t know what to do about insulation as I need to keep it all breathable. Any suggestions or advice would be great. Thanks
Peter9791
That’s back face of the external wall. It’s done in a header bond with some bricks laid sideways. So essentially another wall that is interconnected with it.

JohnD I assume you’re talking about my original picture and not the second one with the Kingspan ?
