Introduction: Brick mortar, while durable, can degrade over time due to weathering, settling, or poor initial application. Fortunately, repairing mortar is a manageable task with the right tools and techniques. This guide will walk you through the step-by-step process of fixing brick mortar to restore both the appearance and structural integrity of your brickwork.

Step 1: Assessing the Damage

Before you begin any repairs, thoroughly inspect the brickwork to identify areas of deteriorated or damaged mortar. Look for cracks, gaps, or areas where the mortar has crumbled away. Take note of the extent of the damage to determine the scope of the repair project.

Step 2: Gathering Materials and Tools

To fix brick mortar, you’ll need the following materials and tools:

  • Mortar mix
  • Trowel
  • Pointing tool
  • Bucket
  • Masonry brush
  • Safety gear (gloves, goggles)

Ensure that you have enough mortar mix to complete the repair job based on the assessed damage.

Step 3: Preparing the Mortar Mix

Follow the manufacturer’s instructions to prepare the mortar mix. Typically, this involves mixing the mortar powder with water in a clean bucket until you achieve a smooth, workable consistency. Aim for a mix that is neither too wet nor too dry, as this will affect its adhesion and workability.

Step 4: Removing Old Mortar

Using a masonry chisel or a pointing tool, carefully remove the old, damaged mortar from between the bricks. Be cautious not to damage the surrounding bricks during this process. Use a brush to clean out any debris or dust from the joints to ensure proper adhesion of the new mortar.

Step 5: Applying New Mortar

With the old mortar removed, it’s time to apply the new mortar mix. Using a trowel, carefully pack the mortar into the joints, ensuring even coverage and filling the gaps completely. Work in small sections to prevent the mortar from drying out before you finish.

Step 6: Finishing Touches

Once the new mortar is in place, use a pointing tool to smooth and shape the joints, matching the surrounding brickwork as closely as possible. Take care to create a uniform appearance and remove any excess mortar from the surface of the bricks. Allow the mortar to cure according to the manufacturer’s instructions before subjecting it to any stress or moisture.


Repairing brick mortar is a straightforward process that can be completed with basic tools and materials. By following these six steps, you can effectively fix damaged mortar and restore the strength and aesthetics of your brickwork. Remember to work carefully and patiently, and your repaired mortar joints will blend seamlessly with the rest of your brickwork, ensuring a durable and visually pleasing result.
