A: The best course of action will be to remove as much of the loose material as you can. Once the High Heat Mortar as been appiled and it has set, it should seal properly. This product is not UL certified however. I have used this type of product on the firebrick inside my fireplace with good results.

A: DAP High Heat Mortar is designed primarily for small touch up repairs. For larger and more involved repairs, a dry mix refractory cement may be the better choice. Given the age of the fireplace, a proper inspection by a professional may also be in order.
