Bricklaying isn’t just about stacking bricks—it’s about finishing them properly. The jointing (how mortar is shaped between bricks) affects not only how your wall looks, but also how strong and weatherproof it is.
Here’s how to joint brickwork like a professional:
1. Wait for the Right Time
-
Don’t rush! Let the mortar partially set.
-
Test it: when a light finger press leaves a mark but doesn’t stick, it’s ready.
2. Choose the Right Jointing Tool
Different tools create different finishes:
-
Concave jointer (bucket handle) – Most common, smooth and strong.
-
Weather-struck jointer – Angled to shed rain.
-
Flush jointer – Flat with the wall, good for plastering/rendering later.
-
Recessed jointer – Creates a shadow line, often decorative.
3. Compress the Mortar
-
Press firmly into the mortar joint with your tool.
-
This compacts the mortar, making the joint strong and water-resistant.
4. Keep It Consistent
-
Work in straight lines, one course at a time.
-
Make sure every joint is the same depth and finish.
5. Clean as You Go
-
Brush away loose crumbs of mortar before they set.
-
Wipe down smears for a clean, professional look.
6. Pick the Right Finish for the Job
-
Concave joints = best durability and water resistance.
-
Weather-struck joints = good for exposed walls.
-
Flush joints = useful if the wall will be painted/rendered.
-
Recessed joints = modern, decorative look.
