It worked! We've had a few heating/cooling cycles now and the crack stays gone. There's a few hairline cracks in the surface but those are just from the heat drying the limewash out too fast and a second coat (applied when cold) should get rid of them too.
Thanks to whoever suggested this. Can't remember who, maybe @valentinzi?

Limewash is an interesting material. It's not paint, you just throw a bunch of slaked lime into water and keep it there. The longer you keep it under water, the finer it gets.
When you need it, dredge out a quantity of the stuff with enough liquid so it's like creamy yoghurt.
Best applied with a thick brush, likes to splash everywhere and is caustic enough to etch an aluminium ladder, so protect yourself.
It goes on looking thin but hardens by absorbing atmospheric CO2 (yup, carbon capture, or recapture at least) and turns whiter as it does.
Unlike cement and many modern paints, it is moisture permeable and so lets the log "breathe" and not rot underneath.
It's also antibacterial, so used to be applied regularly in animal barns.
Too hot outside, so tackled some work in the kitchen.
The wall where we tore out a rotten old shelf looked ugly. The logs are in reasonable shape for their age but the limewash was due for renewal about half a century ago, mostly flaked off and mixed with a few spills.
There were also gaps where the logs had shrunken from drying.
Last winter we gathered some sphagnum moss in the forest and dried it in the sauna.
Great material, as evidenced by the original moss still being intact after 90 years. Nature's spray foam, minus the cancer.
I used a piece of scrap metal to push it in, which worked well, bit like caulking a wooden boat, although it took the entire bag of moss as it compresses a lot.

I'm off to put some more #Limewash on a brick wall.
First I'll mix the powder and water while wearing a N95 mask, glasses and gloves and long sleeves.
Then a wash before I rub a little vegetable oil on hands, forearms, knees and forehead. Keep the glasses and long sleeves.
The gloves I'll change if I get limewash inside. I'm no master limewasher.
ETA completion is 2 hours.
Been using #Limewash and a no cement, no sand #LimePlaster to change walls and a room into something lighter and fresher.
Since read technical documents and I did the lime plaster wrong.
But in this climate on these bricks, it's worked so far.
And whitewash over old acrylic render maybe shouldn't have worked but has.
Here in a lower moisture environment limewash/limeplaster is very forgiving.
Except for eyes - ouch, ouch ouch.
And sratched and abraided skin - mild burns that healed slowly.
Searching the web, looking for a recoat time for #Limewash.
Being lied to by #AIGenerated website content about multiple things limewash and whitewash.
This garbage is being posted by businesses to boost their profitability.
There is freedom of speech on politics and opinions and then there is disseminating factually incorrect technical information.
One of these needs to be criminalised.
(Found a technical bulletin from 2021 with a recoat time of 4hrs at 25 degrees C and 50% rel humidity)
I put on about 6 litres of DIY recipe whitewash today.
Trying to even up the coverage on a rough surfaced and deeply pointed 1970s brick wall.
Seeing now I should have mixed up a thick lime putty and filled all the deeper crevasses first thing - getting limewash into them takes too long. So putty next
Still hopeful that it'll take just one more coat after the putty. And then it'll all look like wedding cake icing.
PS. I learnt to wear goggles doing the first coat Ouch.

@architecture
Splashed #Limewash / #Whitewash on a window.And also wondered about using it in hot weather.
Whitewash has been extensively used to reduce heat coming into greenhouses. And would doubtless function that way for domestic dwellings.
Pros
More effective / reflective than yoghurt?
Cheaper over large areas?
Cons
More risk to eyes/skin when applying / removing.
Prob more mess on and off.
