Remove all existing, damaged mortar from between the bricks. Use a chisel to remove and rake out any mortar to twice the width of the joint. Use caution not to chip or damage existing brickwork when raking and removing mortar.
Clean out the joints with compressed air and a small brush. Ensure that the joint and surrounding area is free of dust, dirt and debris.
Purchase a brick mortar that closely resembles the existing mortar in color and texture. Take a sample of the existing mortar to a home improvement store such as Lowe's or Home Depot for analysis. This will ensure a proper match in color and texture.
Inspect the cracked brick walls to find any other areas affected by the damage. Repair all cracks at the same time.
Mix mortar according to the manufacturer's instructions and apply liberally to the cracks. Push each load of mortar deep into the affected area. Smooth out the joint and allow drying. This process may take up to 3 days.
