Abstract[Bearbeiten]
This research investigates application of desalinating poultices to Locharbriggs Sandstone and Peakmoor Sandstone using different poultice mixes and application methods. The project has two aims, first, to determine the impact of poulticing on subsequent stone weathering response to simulated weathering cycles and, second, to evaluate the effectiveness of different poultice mixes and application methods on removing salt from substrate material. Analysis of surface to depth samples from blocks using Ion Chromatography and Atomic Absorption Spectroscopy identified spatial patterns of substrate salt retention. Visual recording of samples during weathering simulations identified differential weathering response of blocks with Peakmoor Sandstone exhibiting the most extensive surface deterioration. This deterioration was related to the incomplete removal of salts and mobilisation of deep? substrate salt deposits that were drawn up to near surface material. These data demonstrate the importance of appropriate poultice selection and adherence to best practice? during the application process. They also have implications for consideration of adverse effects of incomplete salt removal from heavily contaminated stone.
