The first step is to inspect the bricks in your fireplace. The next is to remove the old mortar. You can use a drill bit or a masonry chisel. Before you begin, it is important to wear a dust mask to protect your eyes from flying debris. It is also best to cover the area with a canvas drop cloth to reduce the amount of dust that is released during the process. 

Once you have removed the old mortar, you need to clean up the area. This is a simple task. A masonry brush can be used to remove debris from the bricks. Next, you can apply refractory heat-resistant caulk to the edges of the firebrick. Be sure to follow the manufacturer’s instructions on how to apply the product. 

If you want to fix your fireplace bricks yourself, you will need to purchase the tools needed. Make sure to match the color of the existing bricks to the newly installed one. Also, make sure to use the correct pointing mortar. Check the International Residential Code to see if the bricks are approved for your fireplace. 

Whether you want to repair the entire brick or just the cracks, you will need to clean the mortar and brick. This will help ensure that you get the best result. Some bricks can be a little messy to clean. To keep them neat, you can use a paintbrush to wipe them down. Using a vacuum to remove any loose mortar will also help you achieve a cleaner look. 

You can buy refractory heat-resistant caulk, which is specifically designed for fireplaces. Using refractory caulk is a quick and easy way to repair mortar joints between firebricks. Refractory heat-resistant caulk is usually a little more expensive than repointing with ordinary mortar, but it will keep your fireplace from bursting. 

Another method for fixing cracked mortar is to use a tuck pointer. Tuck pointing is a technique that forces the mortar into the joint. You can also use a margin trowel. Apply the refractory mortar to the void and then press the new firebrick into the joint. Finally, smooth out the surface of the joint with the tuck pointer. 

Cracked and eroding mortar joints are common problems for fireplaces. These issues occur due to heating and cooling cycles and settling dirt. As a result, the firebricks that are inside the fireplace will start to crack and crumble. Therefore, you should check them frequently. For more severe repairs, you can call a chimney contractor. 

Whether you are repairing a small or large crack, it is a good idea to have a professional do the work. Having the proper tools and the right techniques can be the difference between a successful repair and an unsuccessful one.
