How to preserve weathered wood?

[TWENTY PILOTS]

I am planning an art installation soon. I make all sorts of craft but this is the first time I'm getting into woodcraft for my release. Last time was with fabric, silk and tulle. Now my theme is finding beauty in brokenness, and weathered wood are a perfect subject. My question: how's it possible to preserve it? I'm wary about water and all the insects that might grow or fungi or something if I use it raw and unpreserved for my 3-day installation. All suggestions are welcome.

To preserve it without making it look overly treated, you could try a clear matte wood preservative or a water based poly. Something like Thompson's WaterSeal Natural Wood Protector can keep moisture out while keeping the look raw. Borax mixed in water (about a 10% solution) can do wonders about the bugs and fungi if they ever come

That's an inspiring theme!
Where will you have your installation?
I'm curious to see it!
About your concern, the first and most important thing to preserve weathered wood and prevent issues like you mentioned is to have it thoroughly cleaned and dried!
Afterward, consider a clear, matte sealant or wood hardener.
You can find spray-on options that will maintain the natural look without adding shine.
Just also make sure to apply it in a well-ventilated area and allow plenty of time to dry before the installation.

I have reservations about using Thompson's WaterSeal.
It's primarily a water repellent and often used for outdoor decks and fences but I don't see it 100% effective against insects and fungi for an art installation.
I also heard a story of a guy getting a tacky finish after using it.
I think Borax mixed in water would be more effective but it might leave a powdery residue once dry.
