Took this leaking shower apart today, whoever did this shower did not know what they were doing, so many problems found, one being mastic was used, and another they used Hardi Backer, I know it says it can be used in showers but every shower I've taken apart that was done with Hardi the bottom is always degraded or has turned to mush, as here in a few places in this shower, in my opinion Hardi is the worse underlayment ever, even for floors...
