Have a two story colonial with regular treated pine decking on second floor porch. Looking to replace with a floor I can set ceramic tile on and provide leakproof cover for first floor porch. Any ideas on how to prep second floor joists and provide sound decking for ceramic and also ensure leakproof cover so as to finish first floor porch ceiling?

Is this porch exposed to the elements or enclosed? What area do you live in (weather concerns).
I suppose you could apply cement board over the floor sheathing and then tile but I would worry about the longevity of tile in such an application if exposed top weather extremes.... not to mention that if you raise the floor to much, you won't be able to open the door.

The porch does have a cover by the gable of the roof. The home is in Florida so freezing issues are not a main concern.

A bunch of info on tiling. One thing to look at is his calculator. You put in the joist width, length and spacing. Will give you estimate if your system will support the tile without cracking. One thing I have found out is that CBU doesn't offer any rigidity.

what about treating it like a poured shower pan with a membrane that wraps up the walls. the pour again and tile. (just skip the drain part I guess). maybe schlutter's website might help. other option in just a roof membrane, sleepers, ply then durock?
I don't know, just some thoughts

Before you get too far with ideas I'd check the slope of the existing deck to ensure good water run-off if you get so far as laying tile. I would want 1/4" drop in 10 ft or more. Probably more considering the tiling process may make small pools on it's own. Then maybe think of incoporating a gutter to address the run-off.
