    Green board vs cement backer board for tub/shower surrounds
    Our tub/hand held shower surround currently has green board (mold & waterproofed board) on the walls and is primed and painted. We are wanting to tile the walls, do we need to rip out the current green board and put up cement backerboard or can we put it right over the current green board?
