Abstract[Bearbeiten]
Kinetics for NaCl movement by humidity alone are slow, and NaCl tends to move into mortar (from damaged bricks) when liquid water is present. A sudden disruption of a wall painting on a vault in Kirkerup Church was caused by the crystallisation of sodium chloride. An attempt was made to desalinate the surface and to extract some of the salt from the upper side of the vault. Various ways of applying moisture to the vault were tried. Both lime mortar and a specially designed salt-extraction mortar were tested as a sacrificial plaster. The main problem was that the salt redistributed within the vault because of the water supplied by the mortar. The main benefit of a thick mortar on top of the vault is to protect against moisture from above.
