salt efflorescence Explanation: http://www.buildingconservation.com/articles/salts/salts.htm -------------------------------------------------- Note added at 7 mins (2007-04-05 19:49:13 GMT) -------------------------------------------------- As drying/evaporation occurs at the masonry face salts crystallise out of solution producing the white crystals known as efflorescence. Inevitably the salts will find routes through the masonry to a drying face/zone, either at a gap in the impervious layer or behind it, where they will continue causing damage undetected. In such a situation lime based plaster or render is always preferable. Although the lime plaster may eventually fail locally with salt efflorescence and need to be renewed, it will protect the underlying masonry, behaving sacrificially to the masonry in the same way that soft lime based mortar repairs applied to sculpture behave sacrificially to the limestone surface. http://www.buildingconservation.com/articles/salts/salts.htm Wörterbuch Bau - Cornelsen |
