I need to redo a tiled bathroom wall (originally done around 1940). Because the existing tile was done with cement, metal mesh and lath; I want to find a way to take the wall down in sections (between the 16" studs). I thought I'd use a circular saw to cut the sections (hopefully that will keep the dust down); but I don't know what kind of blade to use, that will cut through tile, cement, metal mesh, and lath. Any suggestions? By the way, I'm not trying to save the existing tile. On the remodel, I'll be using backer board applied directly to the studs.
