Leaving pine shiplap siding unfinshed
I’m planning on siding my house with locally sourced shiplap installed horizontally with a rainscreen gap. The house has generous (2′-6′) overhangs all around. I know that unfinished wood has been used on farm buildings for a long time. However, farm buildings can let in a little water and smell a little mildewy without causing to much trouble. I do like the unfinished look.
If protected by overhangs and proper water management, am I making my siding more likely to fail by leaving it unfinished? Is there any treatment that I should consider to make the wood last longer?
