Sadly, I think you’re probably right.
What’s made me take a few takes, is that there are surface finishes on top of it that appear historic based on their colouring… I think it’s just tricking me!
Looks very aggregate heavy, with tell tell black under in one image…
What’s the wall? Brick? How old? How thick?
It looks pretty sodden, so I’m assuming it’s coming off, the question is how much damage it will do in the process to the underlying material.
The thing is, if it’s sodden, it will have dissolved the faces of bricks and they’ll come away with the finish. Should come off easily enough then, but could need to be careful not to take too much brick. you’ll then need to wait some time for it all to seriously dry out then consolidate the lost depth as part of the lime plastering process next year.
If it’s not sodden, brittle stuff often comes off relatively easy in big sheets. Sharp perpendicular taps from a club hammer across the surface help delaminate it, then pocking it with a pointy SDS bit again straight in to the surface can initiate cracks to work with. Then either a very long bar carpenters tapped behind, to lever off or a selection of chisel bits on the SDS going gently. The angled tile remover bits are good, to focus damage away from the wall.
You’ll find your method, and it will work really well, until you stumble across a section of wall where it just doesn’t work!

It was only noticable whwn it come through the wooden battening, so who knows how long for. The house is 300year old cottage but this looks to be an extension of some kind just cant find anything about it.
The major issue we have is the outside of the window is just below it, meaning this wall is below the neighbours ground, not alot we can do about that. I was thinking of knocking it all off, wood wool boards and then lime plaster

Being hard is good, as long as you can get it to delaminate.
I wouldn’t bother with woodwool boards, just a thick plaster straight on. Don’t go for hemp, if it’s going to be continually damp as it can often rot and stain through.

It looks strangely attractive in a way, a bit reminescent of a rather shabby Venetian palace.
Im guess thats paint stuck on it. Hopefully it will come off in a nice big piece. (wishful thinking)
