You need to paint it. It absorbs water. It's basically cardboard in concrete.
Actually, I've seen used tar paper used extensively in many climates as a vapor barrier. It's harder to work with than tyvek. Tyvek is very often seen put on backwards and inside out, and seems to make little difference.
Nothing will stop mold in this climate, as far as I'm concerned. Build so it won't bother you.
