Grinding and sealing sandstone yorkstone

Description:

This Waterloo Bridge, London, case study records grinding and sealing of sandstone or Yorkstone flooring. The original notes specify an anti-stain sealant. The gallery includes views of stone paving and a working area, helping place the treatment in context. Yorkstone can vary considerably in texture and absorbency, so a finish should be chosen after inspecting the actual slabs.

Grinding is a surface-removal step used when cleaning alone is insufficient for the stated aim. The depth of treatment must respect the stone’s condition, joints and any previously repaired sections. An appropriate sealer can reduce some staining, but it does not make the stone immune to every mark, moisture problem or acid exposure. The original record does not identify the product or provide a measured slip rating. The photographs document this assignment rather than a guaranteed outcome for another site.
