Installing heavy tile on 20' living room wall

Hey guys,

I'm going to be tiling a section of a wall (with an electric fireplace on it) that is 20' tall. It currently has painted drywall. How can I install heavy 12x24 ceramic tiles on it? Should I put up backer board over the existing drywall, should I just use a stronger thinset directly on the painted drywall, or something else?

I want to make sure the adhesion is strong so the tiles don't fall and potentially hurt/kill somebody...lol.

Thank in advance!

Your strongest bond will be to cement board using a large tile format thinset. Remove the drywall and install 1/2" cement board with screws. Tape and thinset the joints. My favorite thinset for walls is called Ultralite - by mapei. It is super sticky and will make the job go easier. Other thinsets may tend to sag with the heavy tile. Ultralite will be found a tile stores, not boxstores.
