First, you’ll need to remove any loose mortar. You can use a chisel or a small wire brush. Once the loose mortar is removed, you can fill the gap with a new coat of mortar. Before applying the new material, you should clean the brick to ensure there is no dirt or dust. 

Next, you will need to clean the joints with a shop vacuum. This will get rid of any dust or grease. After the mortar has been cleaned, you’ll need to mix some heat-resistant mortar. To make the mortar, you’ll need a paint stir stick and some water. Mix it in a small bucket. Then, you can fill a grout bag and apply the mixture. 

While you’re at it, you might want to give the mortar in the bricks a light spray with water. This will help smooth out the joint and allow it to dry. In addition, you should remove any excess mortar. 

Finally, you will need to put some fire cement in the joint. Fire cement is a type of cement that helps maintain structural integrity while fluctuating in temperature. Apply the cement with a trowel and then let it set for at least 15 minutes. 

If you aren’t comfortable mixing the mortar on your own, you can get a mortar mix from a hardware store or home improvement store. But be sure to follow the directions on the package. Alternatively, you can buy a caulking gun, which is a useful tool for this process. 

When applying the new mortar, you’ll need to start at the top of the chimney. Work from there. Fill any horizontal or vertical gaps. Use your other hand to guide the nozzle. Make sure the caulk has been forced into the gaps as deeply as possible. Let the caulk cure for at least an hour before you begin the next step. 

If your mortar isn’t in very good shape, you can always hire a professional. A chimney sweep will be able to check your fireplace for any signs of cracking or decay. Additionally, he or she might report other damage that requires attention. 

Unless you are very experienced, you may want to hire a professional to do the repairs. They will be able to help you achieve a smooth, professional finish. It is also important to use the right tools. Having the right tools is crucial for successful mortar repairs. 

A tuck-pointing trowel is an important part of fireplace mortar repair. A tuck-pointing trowel looks like a long, narrow chisel. The blade of the trowel should be wide enough to fit comfortably in your hand. Using the edge of the trowel, scrape off any excess mortar. This should be done on all surfaces of the joint.
