Wooden vivarium - is it suitable?

[reptitat]

I have a huge wooden vivarium which was previously used for a tortoise until I realised it was unsuitable for them, so now i'm stuck with an empty vivarium. I was wondering if it would be suitable for a dart frog, unsure of which kind, or would the humidity destroy it? I'm also going to add expanding foam to create a custom background.

Thank you.

Posting a photo will help determine what is required; but if using for Darts, will need to seal up all exposed wood or they high humidity will rot it.

It looks a lot like this:

What sealer should I use? Would the expanding foam still work if I seal it?

It's important to use a SEALER not a SEALANT. a sealant, like silicone, will only cover the surface of the wood, while a sealer will actually penetrate the wood and protect it. Marine epoxy is the best for that, but it is pricey. I have heard about others who have used lacquers, polyurethane and shellac.

I have a large wooden enclosure build planned and I am going the marine epoxy route. I don't mind the added expense to ensure it lasts a long time.
