Is lime plastering neccessary? (internal walls)

[Dace]

For relevant older properties we know it's a good idea to use lime render, does the same thing apply to internall walls? Seems if breathability is important then materials used on both sides of a wall should be considered. Or is normal plaster inherently more breathable than render, making this a waste of money? thanks.

Pointless having lime on one side and gypsum/cement on the other

My personal experience, in an 1890's stone house:
A previous owner has skimmed over the lime plaster - wherever this has been done, the plaster has blown.
Where the lime plaster has been wallpapered, the walls are fine; there are many small cracks, but they were easily filled.
Where the brick fireplaces have been taken back to brick and replastered, everything is fine.
Where the lime plaster was sound, but way off true, I have fixed plasterboard to them (or drylined) and skimmed - so far so good!

Sorry, I would disagree!
I had very wet external walls, render on the outside, gypsum and render as 'damp proofing' on the inside.
Removing the render on the inside, and repointing in lime allowed the wall to dry out beautifully. Moisture may still come into the wall from outside, but it is free to evaporate out again. Its not perfect, but definitely better than nothing!

I think we're having that old internal wall/internal side of an external wall confusion....
Can the OP clarify which it is?

Also, what kind of wall? Cavity vs solid will have different answers

There will be a different answer for every scenario.
