Best answer

Add cement board to the entire area you'll be tiling (for us, that means the floor and all 4 sides of the fireplace leaving room for wood mantle). On the ground and drywall, use thinset and screws to attach the cement board. But on the metal surround, use high heat adhesive to attach the cement boards.

Do you need a vapor barrier behind cement board?

By having the vapor barrier behind the cement board you stop the moisture going further into the wall.
