Bathroom drywall

user-6651407 | Posted in Green Products and Materials on

I have been searching, but not coming up with a clear answer.

We are planning on using Dens Armor in our bathrooms walls, with the exception of Cement around the shower enclosure and also Cement as a tile backer.

With regards to the shower ceiling, is Dens Armor suitable?

    DensArmor Plus is suitable for ceilings. (See the screen shot below from the installation instructions.)

    The pdf file of the installation instructions is available as a link from this web page: DensArmor Plus® Interior Panels.

    If you have further questions, call the DensArmor Plus technical support number: 1-800-225-6119.

    I was questioning specifically the shower ceiling. I see some mention they use above shower. I did call GP yesterday, and they stated as long as greenboard can still be used per code, Dens Armor can be used. But I was under the impression greenboard couldn't be used any longer.

    Greenboard isn't suitable as a base for tile, but it can still be used for walls and ceilings (as far as I know).

    If you want to install tile on your ceiling, you will, of course, need tile underlayment.

    If you just want an ordinary painted ceiling, DensArmor Plus will work -- as long as this isn't a steam bath (just an ordinary shower).

    You could look into under tile waterproofing systems. Some of them, to my understanding, such as Schluter Kerdi actually say you can use them over greenboard for waterproofing.

    In my area, greenboard is allowed on the ceiling, but must have specific strapping either 12" O.C. or 16" O.C. with specific nailing patterns. Even then I would still not want it on the ceiling as it has a tendency to stay wetter and sag.

    I would double check with your jurisdiction. My jurisdiction is still pretty lax and far behind on newer codes that they supposedly enforce, but there are others that they will nab you all day on.

    Thanks, yes, just shower (not steam bath) with no tiles on the ceiling.
    We also plan on having adequate ventilation, installing a timer for the vent fan to run 30 minutes post shower.
    I really like the Dens Armor, so I was hoping to use it all over the bathrooms.
