Green Board vs. Hardibacker?

Dear Matt,

I’m remodeling our bathroom (I’m a first timer) and I am using green board on the walls. What I don’t know about is what to use behind or above the shower surround. We also have a 7ft plaster ceiling that I would like to replace because the paint is peeling. It seems to get worse as time goes on so I’m hesitant to prime and paint it as is. Any help would be greatly appreciated. Thank you!

Dear First-Timer,

Great questions! I would recommend using Green Board for the ceiling but not for behind a tile surround. Behind the tile, I would recommend Hardibacker or a traditional concrete float. As far as the ceiling area where you’re experiencing a lot of moisture and paint peeling, my recommendation would be to tile that location.

Hope that helps answer your questions. Best of luck!

    Im reduing a shower, and just follwing what the last ouner did because Im a new home ouner, the groute was cracking and so where some of the tiles, when I removed the tile I found cement board, ontop of drywall (not green board)
    I have removed the old stuff and put up green board ans was going to use hardie backer ontop of the green board, is this a bad idea? if so can you point me in the right direction.

      Hi Kevin,

      Thanks for your question! There is no need to use the greenboard. Hardibacker is a sufficient substrate on it’s own.

      Hope that helps!
