   I make a deadman, similar to what you might use for cabinets. That will hold the tiles for a few hours (overnight is better) until they set up.

   *Let's see now; I'm a guest in your house when that heavy tile lets go(moisture, earthquake, etc) and pops me on the head. While that may be an improvement in some people's minds it definitely won't be in mine or my attorney's. Especially since I've never seen large tile used in the ceiling in a high moisture environment.Now this doesn't mean don't do it. Just make sure the entire structure is specifically designed and inspected with future liability in mind.

   *FHB had an article on how to do this a few issues back. I would also suggest using latex modified thinset. Can't beat the grip (worked like a charm for me). Yours would probably require the deadman until set, because of the size of the tile. Ditto the extra support structure in that ceiling.

   *What is the ceiling now? I definately wouldn't attach that heavy a tile to a painted ceiling. The best thing would be to glue and screw 1/2" cement backer board directly to the ceiling joists, screw every 6". Also, be sure to use the special screws for cement board. Drywall screws have too small of a head.Use latex modified mortar to attach the tiles. The suction should hold them as long as you dont mix it too thin. If they hold for 10 minutes they'll hold till hold till they dry. try a few and see.

   *Try latex modified speed set. The speed set sets up alot faster. A dead man is always a good idea but not totally needed. The substrate your sticking to is real important. cement board like the other post told you about is crucial.

   *Thomas - You can get the TCA (Tile Council of America) Installation Handbook which addresses such applications and sets acceptable parameters for substrate, setting materials, etc. Note that you can post technical questions there too.We've designed for 12 x 12 x 3/8 marble on a ceiling and it hasn't come down - yet.Jeff

   So, I've done five or six tub surrounds and am pretty confident with tile basics and layout But- I'm adding a jacuzzi tub in my basement and a 12in support beam runs along the ceiling and will trap some moisture at the ceiling so I've decided to tile the ceiling as well. I'm using 13by13 tiles and don't know if I have to brace the tile while it sets or if I need a different product to secure large tile to a ceiling. If you have any advice let me know. I'd hate to have 13in tile raining down on us in the tub. Thanx
