A band trowel is a specialised masonry tool with a narrow, elongated blade, used for applying and finishing joints in brickwork. It is indispensable for the neat finishing of bed joints.
Shape and features
The band trowel is distinguished from a standard bricklaying trowel by its narrow, elongated blade. The blade is typically 10 to 20 millimetres wide and 250 to 300 millimetres long. This slender shape allows the bricklayer to apply mortar precisely into the joints without soiling the surrounding bricks. The handle is ergonomically designed and usually made of wood or plastic.
Applications
The band trowel is primarily used for:
- Bed joints: Filling and finishing horizontal bed joints (the joints between horizontal courses of bricks).
- Repointing: Refilling raked-out or weathered joints during renovation or restoration work.
- Neat finishing: Smoothing mortar in the joint to create a clean and uniform appearance.
During repointing, the old mortar is first removed from the joint. Fresh mortar is then applied into the joint using the band trowel and worked to a smooth finish. The narrow shape makes it possible to work precisely, even in hard-to-reach joints.
Difference from other trowels
While a standard bricklaying trowel has a wide, triangular or trapezoidal blade and is intended for applying larger quantities of mortar, the band trowel is specifically designed for fine work on joints. A jointing iron is sometimes used as an alternative or complement, but offers less control when applying mortar.
Maintenance
After use, the band trowel should be cleaned immediately to prevent mortar from drying on the blade. A well-maintained trowel will last for years and consistently deliver clean joint work.
