Everyone thinks about how to do repointing of brickwork. So, allow us to share our experience and knowledge. Repointing brickwork is the process of removing old mortar and replacing it with fresh mortar. This helps prevent water from entering your walls and keeps your home strong and safe. When mortar starts to crumble, gaps appear between bricks. This can cause damp and damage to your walls if left unchecked. Repointing bricks fills these gaps and protects your home.
Doing brick pointing also improves the look of your house. A freshly repointed wall looks neat and well-maintained, while preventing bigger problems in the future. As experienced roofers, we will guide you step by step through the process so you can carry out repointing safely, correctly, and with professional results.
Tools Needed for Repointing Brickwork
To repoint brickwork effectively, you will need a few basic tools:
- Pointing trowel – for applying and shaping mortar
- Brick jointer – to smooth and finish the joints
- Bricklaying trowel – for handling the mortar easily
- Two buckets – for mixing and cleaning
- Pail of water – to keep tools and mortar workable
- Premixed sand and cement – for a strong, consistent mortar mix
Once you apply the mortar, let it set for a few minutes before cleaning the joints. Use a soft brush or rag to smooth the surface and remove excess mortar for a neat finish. Having the right tools makes repointing easier, safer, and ensures your walls look tidy.
How to Repoint Brickwork
1. Clear the Wall Area
Before starting, remove any dirt, dust, or loose debris from the wall. Make sure the bricks are clean and dry so the new mortar will stick properly. Clear the area around the wall to work safely.
2. Remove Old Mortar
Use a chisel or scraper to carefully remove the old, crumbling mortar from between the bricks. Make sure you remove it down to a solid layer, leaving clean gaps for the new mortar.
3. Work Carefully Around Doors and Windows
Pay extra attention when repointing near doorways and windows. These areas are more delicate, so remove old mortar and apply new mortar gently to avoid damaging the brick edges.
4. Clean and Expose Brick Edges
Brush out any dust or small debris from the joints using a soft brush. Make sure the edges of the bricks are clear so the new mortar can bond properly.
5. Remove Dust from Joints
Double-check that the joints are free from dust or loose particles. Even a small amount of dust can stop the new mortar from sticking correctly.
6. Mix the Mortar
In a bucket, mix your premade sand and cement with water until it reaches a smooth, workable consistency. The mortar should not be too dry or too runny.
7. Start from the Top
Apply the mortar from the top of the wall down. This prevents old mortar dust from falling onto fresh joints below and keeps the work neat.
8. Fill Vertical Joints
Use a pointing trowel to push the mortar into the vertical joints first. Make sure each joint is completely filled, and the mortar touches the sides of the bricks.
9. Remove Extra Mortar
After filling the joints, use a soft brush or rag to remove any excess mortar from the brick surfaces. This gives a neat, professional finish.
10. Check the Finished Work
Inspect all joints to make sure they are fully filled and smooth. Make any small adjustments immediately while the mortar is still soft. Let the mortar set completely before touching the wall.
