Whitish traces of saltpetre on the walls

Saltpeter is a whitish deposit consisting mainly of nitrates, which is preferably grown at the bottom of damp walls. Before the elimination of this nuisance, we must first find the causes of the presence of saltpetre and repair the source of infiltration. Ancient buildings, which have housed animals, can also bring out these characteristic efflorescences, if they are transformed without special precautions (treatment and insulation), in housing. These resurgences can occur under the effect of heat when these buildings are heated.
