Basically I'm getting a guy to do my tile around my tub/shower. He swears you don't need Redgard and we are on a tight timeline so applying it when hung would put us behind anyway (We really have 2 days to do everything). I have two questions.
1) Do I even need Redgaurd. The internet has mixed reviews.
2) Can I apply the Redgard BEFORE hanging the cement baord so we don't have to wait for them to dry once they are hung?

As long as it's Cement Board & not some crappy "almost" cement board stuff. You really don't need the RedGard, but the more protection the better...so go for it. And yes, you can do the boards beforehand. But, hit the filled seams & screws (your weak points) as soon as a panel is ready to give it some time to setup. You'll have to wait for the fills to dry or at least setup anyway. Just try not to anger your helper too much. Plan for a lunch, cigarette, drink, phone or snack break, flip-off the circuit breaker or sneak Mom in with the baby to delay the job a little, it sucks but he's got to grin & bear it.
