Re-pointing replaces loose or damaged mortar in the joints between bricks. It's an important step in maintaining your brick, as it prevents moisture from entering the joint, potentially causing more damage.

Re-pointing Mortar Joints

1. Check the mortar to see if it's loose, cracked or separating from the joint.

2. Remove the loose mortar (figure A) using a hammer and chisel, and then brush away any debris.

3. Add moisture with a sponge to the dry mortar and brick so the new mortar will adhere.

4. Using a pointing trowel, replace the mortar (figure B).

5. Use an 'S' jointer to seal the joint.

6. Remove the excess mortar with a trowel.

7. Brush across the mortar (figure C) to finish.

Safety Tip: Remember to always wear your safety glasses. They will protect your eyes from any mortar that might fly out during removal.

Tips to Remember:

• You can use a trowel instead of a mud board to hold your mortar while re-pointing.

• If working on an exterior surface, make sure to get a good seal on your joint to prevent water from entering the joint. Water freezing and thawing inside the joint can further damage the surrounding mortar.

• When working around a loose brick, you can use a small jointer to hold the brick up and out of the way as you replace the mortar.

• Check your brick surfaces for loose or cracking mortar, and then re-point as necessary.

• Remove any excess mortar, and seal properly to ensure a durable joint.
