Sorry @mrrusty i misread your post above about separation.
Can you explain your Sbr / tanking slurry method please. I’m still considering whether to seal the brickwork somehow to keep the salts in the brickwork (dryzone cream paint-on?). I don’t have the wall depth for overboarding.
Bit of an update on this.
I’ve took a section of plaster off and am monitoring it.
When we dehumidify the room the patches do mostly fade away. When I’m in the room sweating, the patches get darker. Does this sound like the bricks are drawing moisture from the room?
I guess my plan is...
Brilliant thanks @23vc
Will compare the specs on this one and the limelite, they sounds very similar by how you describe, so see which one makes the boldest promises about salts.
Will make an attempt at hacking off and re-doing in the next couple of weeks and will report back.
Was about to ask if rather than boarding I can use some kind of renovating plaster onto the bricks?
Sounds like there’s a few options out there, hasn’t seen the thistle one but will check it out. Thank you.
Have been using a lot of the limelite renovating plaster on various walls / chases so...
No real change in three years no. Same shape and positioning.
It was under white paint so harder to tell. Thought it was weather related whilst the paint was on (leak on chimney or something) but now the paint is off it perhaps points to some sort of salts / infected plaster issue as the post...
Hi all hoping for some advice.
Got some damp patches showing through above fireplace / chimney breast.
Moved in 3 years ago and patches were there so nothing new. Was an open fire but now a log burner with lined flue.
Any ideas what might be the most likely cause?
Have recently sanded paint...
