Terrazzo stairs polishing and repair

Description:

This Hampstead, London, gallery shows polishing and repair of terrazzo stairs. The photographs include older terrazzo undergoing grinding, placing the restoration in a staircase rather than a large open floor. Treads, risers and edges can wear differently, and a local chip or crack may need repair before the surrounding finish is refined.

Terrazzo contains aggregate in a binder, so a repair should be assessed for colour and texture as well as stability. Grinding and polishing can improve a worn surface, but the amount of material removed and the desired sheen depend on the existing stairs. The original notes do not provide a measured area, product brand or slip-test result. The images document this Hampstead work; they do not establish a guaranteed safety rating. For similar steps, inspect every tread and the joints before selecting a finish.
