Description

Verfahren zur Behandlung von Mauern, Wänden o. dgl. zwecks Verhütung des Salpeterausschlags Die Erfindung betrifft ein Verfahren zur Behandlung von Mauern, Wänden o. dgl. zwecks Verhütung des Salpeterausschlags. Sie beruht auf der neuen Erkenntnis, daß die Bildung der Ausblühungen durch bakterielle Tätigkeit verursacht wird, und auf der ebenfalls neuen Erkenntnis, daß Formalin die auf bakterizider Wirkung beruhende Hemmung oder Verhütung der Ausblühungen hervorruft.Method for treating walls, walls or the like for the purpose of prevention of saltpetre eruption The invention relates to a method for treating walls, Walls or the like for the purpose of preventing the rash of saltpeter. It is based on the new one Realization that the formation of efflorescence is caused by bacterial activity is, and on the likewise new knowledge that formalin is bactericidal Effect-based inhibition or prevention of efflorescence.

Es ist zwar an sich bekannt, Putzmörteln und ähnlichen Massen desinfizierende Stoffe, wie Formalin, zuzusetzen. Aber erst die.vorerwähnten Erkenntnisse führten dazu; unter Verwendung von Formalin den Salpeterausschlag an Mauern, Wänden o. dgl. wirksam zu verhindern, und zwar auf einem Wege, der keine anderen Schwierigkeiten bietet als ein gewöhnlicher Verputz.It is known per se to disinfect plaster mortars and similar masses Add substances such as formalin. But only the aforementioned findings led to; using formalin to reduce the rash of saltpeter on walls, walls or the like. to effectively prevent it, in a way that does not cause any other difficulties offers than an ordinary plaster.

Zur Durchführung des Verfahrens geht man beispielsweise wie folgt vor: Die zu behandelnde Mauer oder Wand wird bis auf den blanken Stein abgeklopft, um die den Salpeterausschlag enthaltende Schicht zu entfernen. Daraufhin wird die Wand gründlich mit einer Formalinlösung, die aus Formalin und Wasser im Verhältnis von 1: 25 -besteht, abgebürstet und dann dem Trocknen überlassen. Nach dem Trocknen erhält die Wand einen Kalk- oder Zementbewurf, dessen Anmachwasser mit Formalin und Alaun versetzt ist. Das Mischungsverhältnis von Formalin und Wässer beträgt 1:25, während der Alaunzusatz beliebig groß ist. Schließlich wird auf die so vorbereitete Wand ein Gipsaufstrich aufgebracht; dessen Bindewasser ebenfalls Formalin und Alaun in dem zuvor genannten Verhältnis enthält.To carry out the process, one proceeds, for example, as follows before: The wall or wall to be treated is knocked down to the bare stone, to remove the layer containing the nitric rash. The Wall thoroughly with a formalin solution made up of formalin and water in proportion of 1:25 - exists, brushed off and then left to dry. After drying the wall receives a lime or cement plaster, the mixing water with formalin and alum is added. The mixing ratio of formalin and water is 1:25, while the alum addition is arbitrarily large. Finally, on the so prepared Plaster of paris applied to the wall; its binding water also formalin and alum in the aforementioned ratio.
