The first step in repairing brick fireplace mortar is to remove loose and crumbling mortar. This can be done by hand using a hammer and chisel or by using a power drill and cutting wheel. Be sure to remove the mortar as far from the bricks as possible, but not too deep.
Once the loose mortar is removed, you’ll need to clean and prep the bricks for repair. This is important to prevent any further damage to the bricks and also for the safety of your family.
Make sure to cover your eyes and mouth with protective eyewear such as glasses or goggles when working on a brick fireplace. You should also put a tarp around the work area to catch any dust and debris that will fall on you during the repair.
Next, prepare your tools and materials: a carbide-tipped scoring tool designed for cutting tile backer board, a metal jointer, and a couple of trowels–a brick trowel and a tuck-pointing trowel narrow enough to fit in the brick joints. Then, follow the directions on the mortar package for mixing and applying the mortar.
Before you start, be sure to thoroughly dry all surfaces and the bricks themselves. This will help to prevent deterioration of the mortar and to make the repair easier.
Once your surface and bricks are completely dry, use a mortar mix to fill in the damaged areas. This will provide a solid foundation for the replacement bricks. You can buy a bagged mortar mix at most home improvement stores and follow the instructions on the bag to mix the ingredients and apply the material.
For a better-looking final product, it is important to match the color of your existing bricks. To do this, you can look for a color-matching masonry cement in the store and add the desired color to it to create a match.
Alternatively, you can purchase a matching paint for the fireplace and use it to paint the bricks before applying the mortar. This will give the finished project a more professional and appealing look.
Another option is to apply a refractory mortar. This type of mortar is specially formulated to withstand the high temperatures of a wood fire.
This is the best choice for repairing your fireplace since it will withstand the heat from your fire and resist any future damage. The mortar is made of cement and aggregates such as silica.
You should also match the color of the new mortar to the colors of the old bricks. This will keep the bricks looking uniform and ensure that the repaired mortar blends with the rest of your fireplace.
Once the old bricks and the new mortar are completely dry, it is time to insert the new bricks into the repair spots. You should also wet the replacement bricks to ensure that they are properly bonded and that the replacement mortar adheres to them properly. You should wait a day or so for the bricks to dry into place.
