Cleaning, polishing and vitrifying onyx floor

Description:

This Regent’s Park, London, page documents cleaning, polishing and vitrifying an onyx floor. Four photographs show the onyx surface in the project setting. Onyx often has strong natural pattern and translucency; the visible finish can change markedly with lighting, so close inspection of marks matters before any abrasive work.

Cleaning addresses surface deposits, while polishing aims to refine dull areas. Vitrification is a separate finish treatment and should be evaluated for compatibility with the specific stone and its existing finish. The case notes do not state the chemical formulation, exact abrasive sequence or a guaranteed gloss measurement. The gallery shows this particular job, not a universal recipe for all onyx. For a comparable floor, check the stone identification, any old coatings and the depth of scratches or staining before deciding how much treatment is appropriate.
