und wetterfest zu machen.and to make them weatherproof.

Man hat versucht, zur Erzielung von Wasserdichtigkeit poröse Putz- oder Steinflächen mit einer Seifenlösung zu bestreichen, ohne wesentlichen Erfolg, da gewöhnliche Seifenlösung auch nach dem Eintrocknen leicht von Wasser wieder aufgelöst wird, bis auf die wenigen Partikel die sich mit den in der bestrichenen Fläche zufällig sich findenden Salzen, wie z. B. löslichen Salzen von Kalzium, Magnesium, Aluminium, oder mit etwa vorhandenem Kalk zu wasserabweisenden fettsauren Salzen umgesetzt haben. Man versuchte, die Wirkung der Seifenlösung dadurch zu erhöhen, daß man einem ersten Anstrich mit Seifenlösung einen zweiten Anstrich mit Lösungen von Aluminium, Kalk, Magnesium oder ähnlichen Salzen folgen ließ. Abgesehen von der größeren Mühe eines zweimaligen Anstriches hatte dieses Verfahren nur teilweise Erfolg, insofern sich im allgemeinen nur an der Oberfläche das· unlösliche fettsaure Salz bildete, während in die tieferliegenden Poren der zweite Anstrich, eben infolge der zwar praktisch nur unvollkommenen, so doch anfangs deutlich sich zeigenden wasserabweisenden Wirkung des ersten Seifenanstriches, nicht einzudringen vermag.Attempts have been made to achieve water tightness by using porous plaster or stone surfaces to be brushed with a soap solution, without any significant success, since ordinary soap solution is easy even after it has dried out is dissolved again by water, except for the few particles that are in the coated Salts found by chance, such as B. soluble salts of calcium, magnesium, Aluminum, or with any lime present to form water-repellent fatty acid salts have implemented. Attempts were made to increase the effectiveness of the soap solution by a first coat of soap solution and a second coat of solutions followed by aluminum, lime, magnesium or similar salts. Apart from the the greater effort of painting twice, this process was only partially successful, insofar as the insoluble fatty acid salt was generally only formed on the surface, while in the deeper pores the second coat, precisely because of the practicality only imperfect water-repellent effect, which is clearly evident at the beginning of the first coat of soap, cannot penetrate.

Das vorliegende Verfahren behebt diese Schwierigkeiten vollkommen, so daß ein einmaliger Anstrich zu absoluter Wasserdichtigkeit des porösesten Mörtels oder Steines führt, selbst unter den schwersten, praktisch in Frage kommenden Witterungsverhältnissen.The present method completely eliminates these difficulties, so that a one-time Painting leads to absolute watertightness of the most porous mortar or stone, even under the most difficult, practically possible weather conditions.

Es wurde gefunden, daß die ammoniakalische Lösung von Zinkhydroxyd, in welcher das Zink gewissermaßen nur saure, nicht basische Eigenschaften hat, beim Vermischen mit einer Seifenlösung (Fett- oder Harzseife, deren Alkali ganz oder teilweise durch Ammoniak ersetzt werden kann) keinen Niederschlag des wasserunlöslichen und hochgradig wasserabweisenden fettsauren Zinksalzes erzeugt, sondern daß die Komponenten nach dem Zusammenrühren eine schwach opalisierende wäßrige Lösung bilden. Diese Lösung wird wie Wasser in die Poren jedes porösen Gesteins, abgebundenen Mörtels oder ähnlicher Materialien hineingesaugt, erst beim Verdunsten des überschüssigen Ammoniaks bzw. des Wassers tritt hier die Bildung des wasserabweisenden fettsauren Zinksalzes ein. Dasselbe ist nach kurzem Trocknen nicht nur auf der Oberfläche des Steines, sondern tief in den Poren überall verteilt und macht so den Stein vollkommen wasserabweisend, auch bei höchster Beanspruchung.It has been found that the ammoniacal solution of zinc hydroxide in which the In a sense, zinc only has acidic, not basic properties when mixed with one Soap solution (grease or resin soap, the alkali of which is completely or partially replaced by ammonia can be) no precipitation of the water-insoluble and highly water-repellent fatty acid zinc salt, but that the components after stirring together a Form weakly opalescent aqueous solution. This solution gets into your pores like water every porous rock, set mortar or similar material is sucked into it first when the excess ammonia or water evaporates, this is where formation occurs of the water-repellent fatty acid zinc salt. The same is after a short drying time not only on the surface of the stone, but also deep in the pores and distributed everywhere thus makes the stone completely water-repellent, even under the highest stress.

Gegenüber der bekannten Verwendung fettsaurer Metallsalze in Benzin, Terpentinöl oder ähnlichen flüchtigen Lösungsmitteln für denselben Zweck besitzt das vorliegende Verfahren den Vorzug, daß es wesentlich billiger ist und daß keine Feuersgefahr mit seiner Anwendung verbunden ist.Compared to the known use of fatty acid metal salts in gasoline, turpentine oil or The present process possesses similar volatile solvents for the same purpose the advantage that it is much cheaper and that there is no fire hazard with its use connected is.

Die zur Ausübung des Verfahrens dienende Flüssigkeit wird zweckmäßig in folgender Weise zusammengesetzt:The liquid used to practice the method is expedient in the following Composed way:

: Man löst einerseits etwa 60 g Ammöniak-: On the one hand, about 60 g of Ammöniak-

oder Alkaliseife in ι 1 Wasser, nötigenfalls unter Zusatz von etwas Alkohol, anderseits mischt man eine Lösung von etwa 8 g Zinkhydroxyd in ioo g Salmiakgeis, vom spezifisehen Gewicht 0,910 mit 900 g Wasser und vereinigt beide Lösungen. Die Seifen werden zweckmäßig aus gereinigter Ölsäure herge^ stellt, doch ist die Verwendung von Seifen anderer Fett- sowie Harzsäuren nicht ausgeschlossen. or alkali soap in ι 1 water, if necessary with the addition of a little alcohol, on the other hand one mixes a solution of about 8 g of zinc hydroxide in 100 g of ammonia ice, of the specific type Weight 0.910 with 900 g of water and combined both solutions. The soaps will It is conveniently made from purified oleic acid, but soaps are used other fatty and resin acids not excluded.
