Waterproofing Melamine

[Layna]

Hey all-

I've got a question about Melamine. I plan to use it to when making my cages for both my corn snakes and ball python. I am concerned as how to waterproof it, since upon reading up on it, I learn it warps when wet. The humidity range for corns is around 40-50% (bumped to about 65% in shed) and ball pythons is approx. 50-60% (bumped to 70% while in shed).

So now I read else where a way of "waterproofing" would be to cover the inside surfaces with clear contact paper and then caulk the edges, sealing it up. Do you guys think this would work?

Or should I use polyurethane and then seal the edges with caulk or aquarium sealant?

Yeah you can use polyurethane after chaulking the joins. Just put a few coats of the polyurethane and let it air out well.

Thanks I'll go with the polyurethane then.
