   First and foremost, read the labels.

   Tile over regular Drywall

   I normally would prime the drywall at least first. Read the lable of the thinset. some thinsets are not recomended for natural stone, and some are not recomended for porcelian. I do recomend also back buttering the porcelin tile also to make sure the thin set adhears to the tile.

   Thinset can be used over drywall. If the drywall and mud are raw and unprimed as in new construction, I recommend priming.

   I recommend using a modified thinset. You can buy a bag of thinset that's already modified, or you can buy an unmodified thinset and modify it with a liquid latex admix.

   Because you're using granite, I don't recomend using mastic, as mastic can stain/blotch/discolor some natural stones.
