How to Preserve a Log7/11
I have numerous 24" and larger perfectly straight Tulip Poplar trunks around 10 feet long each. I want to make some benches out of them to sell locally. I have a large supply, so its a concept that I am looking into. Basically, we would cut about 1/3 of the girth away exposing a flat area about 18" wide (down the whole length). Is there a way to preserve the wood so that it does not rot in a year or two? Untreated, this wood goes south fast. Do they have to be suspended (i.e., not resting on dirt)? Or am I wasting my time?
Thank you, Ralph
You will have to put it under water as in a pond or keep it continually wet with sprinklers so that the oxygen is driven out of the wood (anaerobic condition). However, not very easy and practicle to do.
Try copper Napthylate- it will cause a green or brown coloration to the wood, but it will keep out the powder post beetles!
I assume these benches will be outdoors because it sounds like a rustic design, and if so, Poplar is one of the worst woods for outdoor use unless you are diligent about painting it every year.
