I wrote last week about doing the chaux chanvre at the top of the staircase tower.
The other walls of the tower need finishing too, and most of this is being done the same way we finished one of the staircase walls last year, even down to the amount of dust created by removing the old render.
stones to a depth of about 3cm
to dry slightly (about 12 hours), it is brushed back
with a wire brush to expose however much of
the stone you want to see.
