Fireplace mortar is essential for patching cracked or chipped fireplace refractory, or filling missing mortar joints. The A.W. Perkins brand is a trusted product that we highly recommend for this job! You can fire it immediately - the material requires 1200°F to strengthen the mortar to firebrick hardness. Once it is fully cured, it will withstand temperatures up to 2000°F! This high quality gray mortar is ideal for indoor applications.

Silicone & Caulking Tips: DiY like a Pro!
- Product cartridge fits into a standard caulking gun. For clean application, cut the cartridge tip near the end, at an approximate 45° angle.
- Ensure that the working surface is clean, dry, and free of debris. Have some damp cloths or a roll of paper towels within reach. Lay down newspaper to protect carpet/flooring from possible drips.
- To lay a professional bead, hold the caulking gun at 45°. Spin the cartridge tube so the longest part of your tip is aligned with the top side of the caulking gun.
- Beginning at the highest point of your working area, slowly and gently squeeze the trigger and drag the gun to lay an even bead (about 1/8").
- For a clean job, remember that "A little goes a long way!" Try to be consistent when laying a bead - you can always go back and add more material later.
- As you near the end of the working area, release the trigger (or press the release lever) to stop the flow of material.
- After applying the material, let it cure for the indicated amount of time (at room temperature) before using your appliance.
