    My husband and I were originally going to install a shower kit, but have since changed our minds and want to do a tile shower.
    The thing is, we've already installed, mudded and sanded the green board there nothing we can do (like cover it with something) or are we going to have to rip it out (where the shower will be) and install a waterproof wall material?
    Thanks so much!

      You people should do some FREE research yourselves. You all sound so incapable. For WET areas such as tubs and showers...USE CEMENT BOARD.

    I have the exact same question as her so you could call me as well? Lol. I'm terrified they have me the wrong answer.

    Our condo apartment is adjacent to a common laundry room and four times in the last four years it has flooded due to a faulty washing machine. They will not fix the breach in the wall so how and what products can I use to stop the water from penetrating the wall into my unit. I have had to tear up the padding and carpet and am afraid to replace it with anything until I can figure out a way to seal up the concrete.

    Thanks for the article. Since green board is not suitable, what *would* you use behind a glue-on acrylic tub surround? thanks, -nikita

    I have to do an inexpensive tube job. What backing would you use in tub area, to go under sheets of FRP and glue

    What a great article you have introduced with us. Really inspiring. It is commonly the result of roofing and plumbing leaks. When walls are wet but haven’t been that way for more than a day, your best bet for reducing water damage is to allow air in from outside. Air circulation will help to make your walls dry faster than they would on their own.Thanks for great job .

    Since you do not recommend green board for the shower area, what material do you use before you tile this area?

    Hi Tim,

    My husband wants to use the greenboard product in our bedroom. Not because of moisture issues but just because. My question it a safe product to use regarding health wise? What is it treated with to be mold resistant? Would one use it for entire home construction if they wanted to....cost not being an issue?

    I have a good question. I have a very big bathroom. Do I have to put the mold resistent drywall in the whole bathroom including ceiling or can I put it only where water might come in contact like the sink toliet and shower area.

    we are building a home and the builders would like for us to put tile in ceiling not yo get the dryeall damaged, since we are putting glass walls all the way up. I really dont see why this could be a problem since I have seen a million pictures without the ceiling tile and glass walls all the way to the top! what is yoir opinion on this?
