Bush hammer

A bush hammer

A bush hammered concrete surface

A bush hammer is a masonry tool used to texturize stone and concrete.

Bush hammers exist in many forms, from simple hand-held hammers to large electric machines, but the basic functional property of the tool is always the same - a grid of conical or pyramidal points at the end of a large metal slug. The repeated impact of these points into stone or concrete creates a rough, pockmarked texture that resembles naturally weathered rock.

Bush hammers can help to increase bonding effectiveness when applying new concrete to an existing concrete surface by increasing the surface area of the bonding zone.
