Where’s the job?

Overview

• Repointing involves the removal and replacement of deteriorated mortar between bricks to restore integrity and appearance.

• Skill level: 3 / 5 (requires care in removing old mortar and accurate application of new mix).

• Typical duration: 1 – 3 days depending on the façade size, weather and mortar curing time.

Safety First

• Wear eye protection, gloves and a dust mask when removing old mortar to safeguard against debris.

• Use secure ladders or scaffolding when working at height.

• Ensure the work area is stable and free of obstacles.

• Be cautious of falling debris when chiselling out old mortar.

Tools & Materials

Step-by-Step

1. Remove the old mortar carefully using a chisel or mortar raker to avoid damaging the bricks.

2. Clean the joints thoroughly with a stiff brush or water jet to remove dust and debris.

3. Prepare a new mortar mix as per the manufacturer’s instructions.

4. Dampen the brick joints slightly before applying the mix to improve adhesion.

5. Fill the joints with the new mortar using a pointing trowel, making sure to work it in fully.

6. Tool the joints smoothly for a consistent finish and to compact the mortar.

7. Allow the new mortar to cure as recommended before exposing it to the elements.

Completion Checks

• The mortar should be evenly distributed and fully set with no visible gaps.

• Ensure the joints are smooth and weatherproof without compromising the brickwork.

• Check that no damage has been caused to adjacent bricks during the repointing process.

• Verify that the new mortar cures in appropriate weather conditions for longevity.

When to Call a Pro Instead

For facades with structural issues, historical significance or challenging access, consult a professional bricklayer to ensure structural integrity and compliance with local conservation guidelines.
