A struck joint is a mortar joint finish in masonry where the excess mortar is cut off at an angle with the trowel, creating a sloping joint face. The sloping face helps rainwater run off the wall properly.
Features
The struck joint is recognisable by its angled profile:
- Sloping joint face, formed by cutting the mortar at an angle with the trowel.
- Made during or shortly after laying (jointing as the work progresses).
- Promotes water run-off along the wall.
- Differs from the flush, recessed and concave (bucket-handle) joint.
Application
The struck joint is used mainly on the exterior face:
- Facing brickwork where a quick finish is wanted.
- Walls that need to shed water effectively.
- Situations where laying and pointing are done in one operation.
