Cabin Chinking recipe

I posted this in another thread, but ill ask again here.
Does anybody have a homemade recipe for cabin chink?

Currently I’m experimenting with saw dust flour and a white paint or primer from the free store to make the chinking light to contrast with my dark logs.

It seems fine any other ideas?

Hi Byron,
I’m behind on my mail but the info may help if you’re not done already.

Thanks Richard,
I did the flour water, mixture but ended up pulling it out. May try the concrete mix!
