I am doing a remodel and the drywall guy left the shower stud bays uncovered so the tile guy put up paper and cement and is ready to tile. In the kitchen and over the bathroom vanities, he drywalled it. Is it ok to have the tile guy either put up lath and cement or wonder board on top of the drywall as a backing for the tile. He says he doesn't want to rip it out if he doesn't have to. Some guy in a store recommended a sealer ... Red Guard and said if you put that on the drywall (green board) it helps the cement or thinset to bond. The tile guy says that is very expensive and not necessary. He also says that good caulking between the vanities and wall is good for water protection. He says that bitchitaneing that joint is also not necessary. I am afraid that water that seeps through a failed grout line can make its way to the drywall behind and cause problems. Any help or advice would be appreciated.
