has ANYBODY used pure Tung Oil to finish an earthen floor?

We are about to lay the earthen layer of our floor... on the order of 400 square feet.
We plan to finish it with pure Tung Oil, and will be prepared to thin it 25-50% with citrus solvent for the first coats, if needed.

I find sites that list Tung Oil as an alternative to linseed, but I can't find anyone who has actually used pure Tung Oil.

We have 5 gallons and I'm wondering if that is likely to be enough. Also just would like to know everything about an experienced person's experience with it! How well it went on, how it cured, how long, etc. We have loads of resources on how to oil a floor, but none of them used pure Tung Oil specifically.

(We are using Walrus Oil's Tung Oil)

(cracks me up that spell check keeps capitalizing Tung Oil -- I'm suprised it isn't adding a TM after it. And looky there, it doesn't bother to spell check my typo on surprised.)

Kimi,

I do not have floor-oiling experience, but I use tung oil for all the wood projects.
I like to warm the bottle first in the sun to make it more liquid (also Walrus brand). I apply it with a paint brush and after few hours I remove excess with paper towel. If excess will be left on low porosity hard wood (for example red eucalyptus) then the next day a gummy layer will form. Pine and redwood absorb it quickly. The floor would also have some porosity so excess oil would be probably absorbed before drying.
I have picked tung over linseed, because supposedly it protects the wood better against elements - it's more water resistant. It oxidizes/hardens faster and it matters a lot when working in my outside, dusty workshop.
I use linseed oil for blackening steel and cast iron.
I'm still considering oiling my (fired) terracota floors and if I do, I would use tung oil for the same reason - the speed of drying.
