Abstract: Problems with damaging salts are often found on historic stone monuments. There are various ways for salts to reach a building material. Especially in conjunction with humidity salts can lead to accelerated weathenring of a material. Reducing the presence of salts to a minimum is irnportant for a lasting conservation treatment of stone objects. Efficiency and applicability of a salt reduction are strictly related to the condition of the object, e.g. the properties of the material and its state. Surfaces which show severe damages from weathering need to be pre-consolidated before any salt reduction rneasures. A conservation treatment that aims at restoring the stone materials original strength influences a subsequent reduction of present salts. In this research, treatments of pre-consolidation and subsequent consolidation are examined as to their influences on the efficency of desalination. On Rhätsiltstone (Rhätsiltstein) which has been contaminated with salts artificially and treated with silicic acid ester, desalination treatments were carried out using cellulose fiber poultice. It was found out that salt reduction is possible after consolidation treatrnent. The efficiency depends on the properties of the consolidation material.
