Bush Hammered finish on sandstone steps

Description:

These bush hammered sandstone steps in Hampstead, London, were changed from a smooth surface to a rougher texture. The original notes say the surface was changed from smooth to rougher texture. The gallery includes the treads, adjacent paving and equipment, allowing the new appearance to be viewed in the context of the entrance rather than as a sample alone.

Bush hammering mechanically textures the stone, but the depth and uniformity should be chosen for the sandstone and its existing condition. Step edges, drainage and adjoining surfaces matter when planning the work. A rougher finish can be intended to improve grip; the photographs do not provide a measured slip-resistance value or prove a particular safety classification. The original page does not record a test result. For a comparable stair, inspect damaged edges and agree the texture before applying it across the whole flight.

Planning a similar sandstone project

Sandstone texture, grain and condition influence the method. Inspect worn edges, cracks and earlier coatings before mechanical treatment. Removing material changes the surface, so a sample area can help agree the appearance. For steps, consider the tread, riser, neighbouring paving and drainage together.

For a similar project, compare the damage and setting with this case study, then discuss the scope before work begins. Explore our stone restoration services and browse the project gallery for other examples. The appropriate process depends on the actual material, previous treatment and required finish.

Care after bush hammered sandstone steps

Keep steps free of loose dirt and inspect edges and joints regularly. Use a cleaning method compatible with the stone and any treatment. A textured appearance alone does not establish a measured slip rating. Where performance testing is required, discuss it as part of the project specification.

For independent background information, visit Stone Federation Great Britain’s stone resources. This resource provides wider context; the treatment for an individual surface still needs its own assessment.

Request advice for your surface

To discuss bush hammered sandstone steps, send Stone Rescue photographs and request an assessment. Include your postcode, approximate area and any known treatment history. Also send a wider view of the setting and close-ups of the damaged sections. We can then explain the next step and whether a site inspection is needed.
