The material used in HMP Prison is a course grained grit stone (Bramley fall), which is used in many of the large buildings in and around the Leeds and Headingly area.
The grit stone is characteristic of many grit stones around the North West and, although it is soft in natural stone masonry terms, it is very abrasive indeed.
The requirements of the local conservation officer and architect included stone cleaning and the removal of surface dirt deposits, without over cleaning (making the stone look new), and without any loss of fine tooling.
The chosen method was low-pressure abrasive stone cleaning at no more than 30 PSI and using Wolverhampton Abrasives “Finesse” as the correct medium.
The results were approved by all parties as excellent given the required end result, considering that the façade is located within a busy industrial city centre and had never been cleaned until now.
This conservation approach to the works ensured that the bank could remain open during works and that the clock tower would not need to be taken down and re-built.
