Thanks for the helpful replies. Lime plaster has been recommended by others. The problem is I've hurt my back a few weeks ago, so I'm quite limited, so I'm looking for the easiest effective option. Regarding sealing the wall and rot, it would not be sealed on the inside. Sealing with linseed oil is done by some, so I'm not sure if rotting is an issue. Naturally is always better, but sometimes not practically possible. I don't think I could find anyone to help with the lime plaster.
The Tung option is interesting, just difficult to get information. We're in the tropics, right next to a rainforest, it get's extremely humid here and can rain for days, although there's little wind, so the walls wouldn't get too wet, it's the humidity that concerns me more.
