Varnishing wood for bed build out Toxicity question

[migx333]

I have a 2005 tundra and im currently building out my sleeping platform in the bed.

Wondering if I can get some suggestions on what varnish to use on my baltic birch plywood I'll be using for my bed build out. Id want it to be weatherproof against condensation due to camping in extreme conditions.

BUT
I'm getting sketched with a lot of options for its toxicity levels/fumes it gives off since I'll be living in my truck full time.
I know majority says that once its fully cured it is close to no toxicity.

- What steps do I follow to properly fully cure it?
- What are my best options for varnishing the wood?
- Do you think I can get away without sealing the wood?

No, ideally full encapsulate before laying down.

Home Depot, ask for stuff explicitly labeled for kitchen counters probably some epoxy. Follow instructions carefully, especially temperature ranges.

Or Tung Oil, natural but pricey

Once it's dried and off gassed it's fine. Usually it takes a week or two for the smell to completely go away. I usually let my stuff dry in the garage (keeps bugs out of the finished product) over night between each coat and then a day after the final coat I put it the sun in my drive way and let mother nature speed up the process.

Helmsman Spar Urethane is my goto. I give it at least 2 weeks if not 4 before sleeping on.

Linseed Oil is simple and effective on birch plywood.
