Hello
I'm working on a basement project. The house is from 1938. I've just started with the first room. I've knocked off all the plaster on exterior walls and plastered with lime plaster. It turned out really well. I can highly recommend lime plaster, even for the inexperienced.
My question concerns an Inner wall. It is currently painted and plastered with original lime plaster that is holding up really well. No hollow spots anywhere. I have tiled a bit before (though not on plaster) and I feel like the wall should be good for tiling.
However, I've read that lime plaster is not suitable as a tile substrate. Has anyone tested this? What are the alternatives?
Should I fill it with house fix and then tile?
Or should I just knock it down and plaster with B-mortar?
The wall is, as mentioned, an inner wall and made of concrete hollow blocks.
Any ideas?

The problem with lime plaster in this context is that it is a weaker layer than the one you want to apply on top. This will result in the underlying lime plaster being able to move, while your added layer cannot do so in the same way. The risk is therefore high that it will detach from the substrate.
Interpreting this as you're voting for knocking down and re-plastering?
If one should aim for the strongest possible base, the concrete hollow block should be the strongest. Smooth out the cleaned wall with some tile adhesive?
If one should re-plaster, should one then choose the strongest plaster mortar, A-mortar?
