Royal Crescent, Bath
We have worked on many projects within the in the Royal Crescent in Bath, the view on the right was taken when we undertook a of extensive scheme of lime based conservative repair to architectural details of the facade (shafts capitals and dentils) we were able to keep stone replacement down to a minimum, although we had to replace some decayed stonework to exposed weatherings.
The first stage of conservation was the removal of surface
pollutants to elements protected from the rain, black carbon deposits to
dentils were removed by poulticing with acid free paper pulp and water
with a little added ammonium carbonate (see pic below). Internally Paint
was conservatively removed from plasterwork and Bathstone stairwell and
hand modelled stucco plasterwork elements reintroduced where missing .
