The chimney sweeps came today. They told my wife that the concrete on the bottom of the fire box, inside the stove, is cracked and needs to be replaced. My wife confirms that this is so. Questions:
- Is this really concrete or just a sand/cement mix?
- Do I need a special kind or just plain old concrete/cement/ whichever?
- What's the cure time before I can start a fire on the new floor?
- Would paving blocks be an alternative? Something like those cement slabs they sell at Home Depot, 1" thick and 12" by 12".
Thanks,
Paul
