The removal of lichen, moss and other organic growth was undertaken with wooden spatulas and stainless steel brushes. The removal of the calcium sulphate deposits on the limestone was achieved by the use of ammonium carbonate poultices. Alongside the cleaning programme, emergency holding repairs were undertaken to all vulnerable areas. This was done by the application of an adhesive lime mortar.

Once all surfaces were clean and prepared, an extensive consolidation programme was executed with the utmost care due to the importance and historical significance of the cloisters. The approach combined the use of adhesive lime mortars alongside the application of a nanolime, CaloSil E25, to grout unstable fissures and assist in stabilising extremely friable surfaces. surfaces. The intention of the conservation programme was to keep all fragments of stone remaining to tell the story of the weathering process of the cloister.

Once all consolidation had been completed, an application of sheltercoat was administered over the whole of the surface area of the cloister bays.
