A structure made of brick is one of the sturdiest, but it can wear over time. Cracks in the brick facade can lead to water damage, insulation problems and other difficulties. You need to repair the facade by replacing the cracked brick and mortar. It's very important that you know the wall completely before you try to repair it yourself. This means knowing the exact type of brick and mortar -- lime or cement-based mortar -- the wall uses so you can use the exact same types.
Things You'll Need
- Measuring tape
Measure the size of the bricks on the facade and purchase replacement bricks that are the same size in addition to the same color.
Mix your supply of mortar according to the exact instructions provided by the powder. Your best way of gauging the mortar's correct consistency is if it sticks to your trowel well.
Chip and gouge out any single section of mortar that are cracked, making sure you get all of the mortar along one side of the brick. Don't remove any other sections of mortar until you replace that one.
Fill in the hole with fresh mortar using the trowel to apply it and wait for the mortar to dry before proceeding further.
Remove all mortar surrounding a single brick using the chisel if the brick itself is cracked or broken and then remove the brick from the facade.
Apply the mortar to the bottom side of the created hole and place the replacement brick centrally on top of it, making sure the mortar reaches the correct height to place the brick. Fill in the mortar the rest of the way and let it dry.
