I am about to tile a small shower as part of a basement finishing project. I've installed Durock in the enclosure, including the ceiling. My plan is to tile the whole thing using modified thinset.

I've tiled the walls and floor outside the shower with good results (using OmniPro), but I'm concerned about tiling the shower ceiling.

Do I need to do anything special to make sure the tiles don't crash down before the thinset dries? For exmple, should I be using a fast-drying thin set?

Any suggestions would be appreciated.

 

If you press the tiles up in the adhesive good, they will not fall down.

Best advice I can give you is if you hear a sucking sound, run like hell.

The ceiling framing should be 12" on center. Use plenty of screws to hold the durock in place. 4" apart on all the framing members is good. Some mix the thinset a little thick for this but I generally don't. I like to burn thinset into the ceiling, and backbutter and notch each tile as I set on ceilings. You could do just the opposite though. Generally, the tiles will stay where you put them. Lotsa drippings so wear a hat and eye protection. Cover the floor and whatever else is in the way.

 

Thanks.

The framing is 16" oc. The ceiling durock is up. I think I put the screws in 6" apart, but I can add a few screws to be safe.

By the way, I realize that I put the ceiling piece of Durock up backwards. That is, I put smooth side out. Do you think I can just score up the face with my carbide-tip scorer to help the thinset grab better? Or, do I really need to take it down and flip it over? The seam between that Durock and the adjacent Greenboard (outside the shower) is already taped, so scoring the smooth would probably be easier.

 

You can use either side of the durock. The rough side is for thinset and the smooth for mastic, but thinset will bond well to both sides. You shouldnt have a problem and dont need to do anything to rough up the surface.
