Redgard - should I use it???
I am really confused. As per our drywallers advice, we have drywall now installed in our shower area and we intended to apply Redgard over it before setting ceramic tiles. The drywaller has seen this done recently on other jobsites and since Regard is supposed to be a waterproof membrane it all made sense to me. When I went in to the store to buy the Regard they said "Oh no, Kerdi is the way to go if you're going over drywall - not Redgard" (and they sell both). What should I do so as to ensure a proper tile installation in a wet area over drywall? Thanks!
