I recently attempted to fix a leak in the Yurt's roof where a nylon strap extends from the outside to the inside transferring the water like a wick. My first attempt was with melted tree sap collected from the Permaculture farm I live on, but that was too brittle once it cooled, so I switched to a beeswax and turpentine mixture which sealed the deal (despite making a bit of a mess!).
