While a fireplace is a source of beauty and warmth in the cold weather, the heat generated from a fire will take its toll on the fireplace over time. The fireplace interior where the fire occurs is called the firebox. Over time, the bricks and mortar can fail due to the expansion and contraction of the materials as they go from room temperature to roughly degrees Fahrenheit and back again. Small gaps in mortar can be repaired with a special high-temperature caulk called refractory caulk. It contains silica for heat resistance and is specifically designed for fireplaces. This fix is a fairly quick, easy, and inexpensive process. Refractory caulk, also known as fireplace mortar, is suitable for minor repairs only.

If you are working on the bricks or hearth of your fireplace, you will have the need to mix fireplace mortar. Fireplace mortar is mixed a bit differently than regular mortar. One of the most important parts of mixing fireplace mortar is to purchase the correct type of mortar. Since the mortar will be exposed to heat you can't use standard mortar.
