Hey all
We are on the last stages of our earthen floor; about to start the sealing process; once our cracks have been smoothed out...
We were planning on sealing with good ol' boiled Linseed and turps, but we heard rumours of some much more natural processes that have much less of a carbon foot print...
So the rumour is something about utilising banana trees (we have bananas on our farm here in South Africa)
You either tap, boil or chop then boil the stalk of the banana tree to achieve a sappy liquid which can be applied as a sealer?
Has anyone ever heard anything close to this method?
The other only alternative natural floor sealant is cow urine/manure. (We have cows on our farm)
The use of fresh cow dung floor is the traditional norm in our region of Africa, but it requires weekly/monthly maintenance.
I saw articles about the use of cow urine in India, but I think that was for anti-fungal properties and not sealing properties.
Blood is another traditional alternative, But we are a vegan based farm so we wont speak about that

...
If you have any follow up info for either of these 2 alternatives, or if you have heard rumour of other alternatives?
Or even if you have some hypothetical theories... Please feel free to add to this topic of discussion.
The oil/solvent option is a great choice; reliable, clean and standardised ratios can be easily found... We will go ahead with this method if we dont find another...
