Steam bath ceiling tile.
 
I am new to tiling and have a project. I have framed in a 3'x7'x7' steam room/ shower combo. It has 4 mil poly vapor barrior and duro rock with the rough (mortor) side exposed. I want to tile top to bottom. I have been told to use mastic on the ceiling, and mortor for the rest. Other advise was use epoxy mortar on ceiling. Also should I also apply Redgard waterproofing. thanks for any advise. hughman

:eek: Mastic is NEVER used in wet locations.

A steam shower is required to use a waterproof membrane ON ALL SIDES that is rated for proper heat exposer over the CBU.
Appropriate insulation is required behind the wall to reduce temperature variations that can lead to condensation.
I believe the poly you installed equates to a double vapor barrier and can lead to a "moisture sandwich" situation.
I'd prefer a sheet-style membrane over the CBU compared to a paint on one.

Angus, i thank you for posting a response. I am getting started and don't know which way to turn. Everyone seems to have an opinion(my plumber and my tile guy) but no one has actually ever installed steam shower. Hughman, i dont want to hijack your thread I just had to chime in. I am going to start a new thread.Thanks Angus!:)

Well what I posted is based off the TCNA handbook (tiling bible) on how to build a steam shower. If your tile guy doesn't follow the specs laid out by the TCNA, I'd consider a new tile guy. Ask him if he's familiar with TCNA method SR614-07.

Also, I forgot to mention the ceiling should be sloped 2 for condensation run-off.
