I've used Wonderboard, but this stuff they're showing me isn't green! I am a renter in a NYC apartment, built around 1960. I have had a leak from the apartment upstairs in my 1/2 bathroom and master bath which share a common wall. The leak comes through the ceiling in the 1/2 bath in kind of a square shape. In the master bath, the leak is only slightly apparent in the ceiling.
We are buying a house in Knightdale NC. My question pertains to waterproof sheetrock or wonderboard. We are having the house built and I have noticed during the drywall inspection that standard white sheetrock is beige used in the bathrooms. Should I request/demand waterproof sheetrock or wonderboard?
