Within the walls of Fishmongers’ Hall, this Scheduled Ancient Monument lies a Grade II Listed hall and a grand staircase, which was cleaned using various treatments, including a poultice for some of the deeply set stains.

The beautiful Nero Marquina floor at this scheduled ancient monument required attention to bring it back to its former glory, as well as ensuring its preservation for future generations.

Thomann-Hanry® interior stone cleaning team stripped back the old surface polish with a strong alkali, which also acted as a cleaning agent. They then polished the surface using multiple diamond pads, bringing back the Marble’s natural shine while ensuring an even finish to all areas.

Finally, to preserve the flooring, it was sealed using our highly popular product, Aqua Fend®. As part of the preservation and aftercare process, the team at Fishmongers’ Hall was trained to look after the Marble flooring using the vitrification method.

The Portland stone facades were cleaned using Thomann-Hanry®’s façade gommage® cleaning system, and the entire project was finished in ten days only.
