Brick walls may be sturdy, but continued use will cause cracks or holes over time. In severe cases, you may need to replace parts of the wall to maintain stability. However, even though adobe walls may seem difficult to repair, repairing them is actually quite simple if you have the right tools. As long as you measure the extent of the damage and cover or replace the damaged part, the brick wall can be repaired to be good again.
Step
Part 1 of 3: Cleaning the Brick
Step 1. Clean the parts of the wall to be repaired
Before starting to repair the wall, clean it first to make sure the cement or mortar is still securely attached. Check the walls for any dirt or cracks. You'll need to patch the cracks and spray the soiled areas before cleaning the walls.
Step 2. File any rough edges
Check the bricks for damage and file off rough surfaces with an iron file. Continue to file until the edges are smooth and even. Thinking will make brick repairs last longer.
Filing will take a few minutes to hours, depending on the severity of the crack or hole
Step 3. Spray the walls to remove dust and dirt
Before repair, the brick wall must be free of dust and dirt. Take a hose and spray the walls to remove any remaining dust or dirt. For more stubborn areas, rub with a rag.
Spraying can be done on brick walls that are outside the room. If the wall is inside, fill a bucket with warm water and wipe it clean with a damp cloth
Step 4. Wait for the wall to dry first before repairing
Repair materials may not stick well if the walls are still wet. Gather additional materials while waiting for the walls to dry. If there are parts that are still wet even after a long time, dry them with a towel.

Part 2 of 3: Patching Cracks with Cement
Step 1. Fill cracks or small holes with cement
Cement is usually enough to glue minor damage to the wall. If the cracks or holes do not damage the bricks in large portions or do not spread to more than a few blocks, use cement to repair the damage.
Step 2. Stir the cement
Buy a bag of ready-made instant cement and pour it into a bucket or cement container. Add the recommended amount of water to the mixture and mix with a hoe or trowel.
If you want, you can make your own mortar, instead of using ready-to-use instant cement
Step 3. Spray any cracks or holes with a spray bottle
Even if the walls should not be wet, spray them lightly to dampen cracks and holes so the cement can adhere better. Fill a small bottle with water and spray the cracks before the cement is set.
Step 4. Cover cracks or holes with cement
Apply cement or mortar with a cement spoon into the cracks in the brick. Cover holes and cracks as deep as possible, then scrape the top with a cement spoon so that the patch on the wall looks even.
Part 3 of 3: Replacing Severely Damaged Brick
Step 1. Crush the old bricks and mortar
Use the chisel and hammer to break the bricks. Remove the lump-shaped part of the brick while disassembling it from around the mortar. Crush the mortar, then remove the dust and dirt before installing new bricks on the site.
To prevent eye injury, wear protective goggles when crushing bricks
Step 2. Stir the mortar
Purchase a bag of ready-to-use instant mortar and pour it into a bucket or wheelbarrow. Add the recommended amount of water and stir with a shovel until the consistency is smooth. Let the mortar sit for 3-5 minutes before attaching it to the wall so that the mortar absorbs moisture and sticks to the bricks more firmly.
Step 3. Apply mortar around the edges of the hole
Pour 2.5 cm of mortar with a cement spoon over the top, bottom, and sides of the free space on the wall. The layer of mortar must be made as even as possible so that the walls are not narrow in part and loose in other parts.
Step 4. Install the new bricks
Place the new brick in place with a cement spoon, then scrape off any remaining mortar. Allow the mortar to dry for 12-24 hours, depending on the mix. Once the mortar is dry and stable, it will turn light gray in color.
