Anyone plastered the interior of their old house with lime plaster?

That's it really.
Thank you.

I haven't heard of R and J before and I live in Dorset. I was worried about using lime plaster on by 1760 barn conversion and wanted to keep it authentic as possible. I spoke to company call Limetec about their plasters and they told me their histocal range of renders and plaster are weaker strength to lime putty and very simple to use over the traditional stuff which take forever to go off.
Anyway, I tried out their stuff and its worked a treat. limetec.co.uk/lime-plaster/

yes.

It is thicker and heavier than "modern" gypsum plasters, both of which improve soundproofing.

It was very noticeable in cutting the sound of people talking, or radio/tv, downstairs being heard upstairs, after the ceilings were restored. Coving and cornices can usually be kept.

This was in an Edwardian house, the finish coat was perfectly smooth. There were some rounded arrises, but also some sharp square ones e.g. on chimneybreasts, matching original. AFAIK the choice was just a style one. You can plaster a square edge without using modern beading. Usually done by tacking a wooden strip to the wall before doing the first wall.

I think lime may make galvanised beading rust, but I don't know.
