Granite Tile Installation
#1

I'm making a 36x48 kitchen table with granite tile top. Using 3/4-inch birch plywood under the tile. I'm trying to decide if I can lay the thinset & tile directly on the plywood, or if I need to first attach a 1/4-inch concrete board on top of the plywood, then apply the thinset & tile? Any ideas/opinions? Thanks!
