Have an old Californian bungalow, we exposed an old brick fireplace. The bricklayer came and fixed it all up and rebuilt the back. I am planning on putting a small wood stove in the area. I have ripped out the old tile and levelled off with a concrete area to the same level of the floor boards as shown. I want to extend the hearth and tile it. I have checked the specifications of the wood stove, it just requires a non combustible material for the hearth , no minimal thickness or R value. For the wood stove, I need to extend our existing area considerably. What is my best option to tile this area, can I use a concrete board ? I wasn't sure about attaching it to the concrete existing area ?
