Since writing about making natural DIY wood sealing oil from Vinegar and Canola oil earlier in the year, we have received many questions from readers.
While we indicated that the natural DIY wood sealer protects raw wood from the elements, some DIYers were concerned that the wood sealant formula might encourage mould and rotting of wood.
In our experience, this has not been the case and the sealer generally works well!
While we make no absolute guarantees, our DIY sealing oil applications on raw wood exposed to the elements outdoors have now lasted two dripping wet, extreme high humidity Summers in Japan. (For those not familiar with Japanese Summers, that is saying something!)
Japanese Summers are notorious for high heat, stagnant moist air masses, and ongoing months of rainfall and storms. Almost any unprotected wood exposed to these sultry outdoor conditions grow mould, moss and fungus on the surface almost immediately.
Unprotected wood is quickly penetrated by moisture and organic growth. Wood rot and decay sets in very quickly afterwards, given the chance. In Winter, the reverse applies. The Winter cold air is extremely dry; and sunshine is strong and high in damaging UV rays. Drying and splitting is the primary concern.
With quick half yearly applications of our home made natural wood sealing oil, we have not experienced any noticeable decay or growth on the wood we have treated. Meanwhile, other unprotected wooden items outdoors have been slimed. The items have decayed and fallen apart over the same period.
Our limited use tests are not definitive, but the DIY wood sealing formula certainly seems to work for us. It revitalizes and protects wood both indoors and out.
