What is the best way to butter up a tile to stick to the ceiling. I've read some posts online about backbuttering the tile and making sure it sucks up to the ceiling. I've read some other posts about putting 5 dots of thinset on the back of the tiles. I am currently thinking over putting a thin coat of thinset on the ceiling then back buttering each tile... Is this sound OK, or is there a better way?
I have LATICRETE Multipurpose thinset for the walls. Is this the product I should use on the ceiling as well.
I am attaching porcelain tile to cement board that has been treated with LATICRETE WaterTight Floor N'Wall Waterproofing. This is for a shower stall, and I have nightmares of the tiles raining down on us instead of water :(
