Hello all! I've learned a lot from all the existing posts but have a question about sealing. I was wanting to know if I still needed to seal the wood of my enclosure even if I wasn't going to stain the wood? The wood is birch and will be 5X2X2 in dimensions, with sliding glass doors.
Sorry your post got missed!
Birch should be fine without sealing it if you are not going to stain it at all, either.
Do you have pictures of your project too?
