Ello,
Tl;dr
Can I lime plaster over Jackoboard (cement backerboard)? I plan to transition plaster from brick to the waterproofed false shower wall.
Currently fixing up our bathroom. I originally was due to replace three tiles and then, after that thread was tugged, the whole bathroom fell apart. I've gone back to brick.
We are in a second floor victorian attic flat, which makes everything slightly more limiting in terms of fixing where outside access is concerned. Oh, and I've discovered over the time that we've lived here that the previous owners were cowboys.
The wall was plastered in a mix of blown plaster and rock solid cement (was like concrete). There's a lot of blown bricks. Where the windows were fit, it looks like a beaver cut the bricks
While stripping back, I also discovered another window that had been covered by plasterboard.
Today, I've blocked out the surprise window and dubbed out the worst of the blown brickwork with a homemade batch of mortar (sharp sand 2.5:1 hydrated lime).
I'll be using Limco to scratch coat the wall and square up the window.
For the concealed shower, I've used backerboard (jackoboard) over battens that sits in front of an old chimney breast. It's an awkward bathroom with eaves that had limited layout options and this was the best solution.
I want to seamlessly transition to the jackoboard, which I plan to tile to the edge of the bath tub/shower screen and then begin the plaster (which will join with the external wall).
Bit ranty... Got a bit carried away with typing then remembered what my question was.
