Is expanding foam waterproof?

I was looking at some "Great Stuff" expanding foam at Lowes. It says on the can that it "provides a permanent air and waterproof bond". It recommends painting exposed surfaces. So, if I paint it, will it keep water out?

I've never used that brand, but all of the expanding foam I've used is not really water proof.... it kind of gets soggy after a while.
