[Cob] Limewash

It seems like

As far as I know, hardening takes a very long time, several weeks or even
months. I have heard it reccomended that you apply limewash in the spring
so it can dry slowly before the summer heat, and then harden over the
summer, before the rainstorms of the autum. That applies to our climate
(temperate and rather wet), at least.
