What is a Bush Hammer and used for?

the article from H. Bliss Last Modified Date: February 13, 2022

A bush hammer is a tool resembling a meat tenderizer that is used by artists and construction workers to add a pocked texture to hardened material like stone or concrete. On a bush hammer, one end of the metal head is rectangular with rows of spikes designed to create tiny pocks in concrete when it is struck. The material is struck with the spiky head multiple times to achieve the desired texture effect. This type of texturing hammer can be either an electric power hammer or a manual hammer. Stone that has texture from a bush hammer is called bush-hammered, phrased like "bush-hammered marble."

Generally, a bush hammer tool designed for manual use will feature a heavy, two-sided metal hammer head with a hole in its center that seats it on a long, relatively thin wooden handle for gripping. Metal used for the heads of bush hammers is often tungsten carbide or steel. The hand-powered version is most frequently used in art, on softer sculpting stones like limestone and marble. Harder stones like granite can be bush-hammered by more powerful electric bush hammer machines, which can also be called scarifiers. The head for a bush hammer is sometimes purchased separately from the handle or hammering machine.

This type of texturing technique can be used to make stone floors non-slip by adding easy-to-grip areas to the surface of the floor. Bush hammering is especially helpful in concrete and stone floors used in rainy climates or near the entrances and exits to showers or pools. When using a bush hammer to add non-slip texture to a floor, extra attention must be taken to avoid adding uncomfortably rough or sharp texture to the floor that might injure patrons. A gently used sandblaster can dull any uncomfortable areas of floor texture that are created while bush hammering the material. Sometimes, stone that has been pre-bush-hammered can be purchased from construction materials suppliers.

Used occasionally in sculpting, bush hammer techniques are most often employed in the field of masonry. In the field of masonry, buildings are constructed out of blocks of material that are held together by a binding agent called mortar. Blocks can be made of materials like concrete, marble, and other types of sturdy stone. The stones are held together by mortar, a paste often made primarily made of wet sand and cement. One common example of a structure built using masonry techniques is a brick wall.

Bush hammered Concrete

Bush hammered concrete is a decorative finish of concrete in which little holes are hammered into the surface, giving the concrete a very nice rough finish with a smooth view. Bush hammered concrete is anti-slip and serves as an alternative for exposed aggregate concrete.

• Anti-slip finish
   
• Ideal for driveways, swimming pool areas, garden paths, public spaces, ...
• Rough surface with smooth look and visible aggregates
   
• Simple and efficient after-treatment of too smooth concrete floors
