Hello,
we are looking for a natural method to protect a spruce wood facade (board-and-batten cladding). We don’t mind if the facade ages unevenly; the main goal is to protect the wood facade without any follow-up treatments. The house is detached, with exposures on all sides, but the largest areas face north and south.
Does anyone have experience with treating wood using fungal cultures? An interesting method could be charring the wood for protection. Has anyone tried this themselves and can share their experiences?
Thank you in advance.

Basically, do nothing. Leave it natural. Wooden facades in the Alpine region or on barns are typically untreated.
If you still want to do something, you can use hydraulic oil, perhaps on the weather-exposed side. I use it for the garden fence, and it has proven to work very well. I would avoid any kind of paint.
Of course, you need to be careful with spruce regarding fungal growth. Always make sure there is no standing water or moisture anywhere.
Once it gets in, it’s almost impossible to remove. So everything needs to be very well ventilated.

However, our wood is rough-sawn, which makes a difference.
We spent a long time considering our options and decided to treat the wood only with a gray-weathering glaze for aesthetic reasons.
So far, one-third is finished, and we like the look; unfortunately, we don’t have long-term experience with this yet.
However, we underestimated the significantly higher effort required to paint rough-sawn wood, as it is sometimes tough to work with. It also took more paint than specified.
I looked into paint and glaze manufacturers, and most of their products are quite similar. Actually, I like Osmo quite a bit, but in the end, we decided against it because we painted in the carpenter’s workshop and didn’t want to occupy the space for long. Also, the temperatures were below freezing, which made outdoor painting impossible with those products.
We ended up using a chalk-based silvering glaze from Kreidezeit, partly because the instructions said it only requires one coat.
I’ve also seen charred wood finishes, which look stylish. Ultimately, our choice was based on what materials we had on site and were able to apply.
