Is Ripstop Nylon Suitable for Gas-Proof Balloon Envelopes?

[GTeclips]

Hello all!

I am looking to begin working on some balloon testing. I have a general idea of how I'm going to perform this. For the balloon envelope, I wish to use ripstop nylon, but I have no clue what would be the best way to make it gas-proof? I have considered coating it with both liquid latex and polyurethane, but I don't want to make a mistake.

Do any of you have a suggestion how to do this?

Thank you, GTeclips

Latex is known to leak a lot, don't use it.

PU is at least mechanically strong.

Thank you Enthalpy, I will tell you how poly works for me.
