Description
Verfahren zur Herstellung von Wandschreibflächen Die Erfindung betrifft ein Verfahren zur Herstellung von Wandschreibflächen und besteht darin, daß die Wandfläche mit Kalkmilch geschlämmt, nach dem Trocknen dieser Schicht zweimal mit klarem Wasser gestrichen, dann im feuchten Zustande mit einer dünnflüssigen Leim-Gips-Lösung so oft überstrichen wird, bis alle Unebenheiten. gedeckt sind, dann die getrocknete Fläche mit Sandpapier glattgeschliffen, danach mit dicker Kalkmilch nochmals geschlämmt und nach dem Trocknen dieser Schicht wiederum mit Sandpapier geschliffen wird. Darauf wird die Wandfläche mit Firnis grundiert und mit einem deckenden Ölanstrich versehen, welcher ebenfalls geschliffen wird, und schließlich wird die Wandfläche mit einem zweimaligen Anstrich von Schultafellack überzogen und mit roten Einteilungslinien versehen. Nun wird die fertige Wandschreibfläche noch mit einem in der Wand befestigten: Rahmen umgeben.Method for producing wall writing surfaces The invention relates to a process for the production of writing surfaces on the wall and consists in that the Wall surface slurried with milk of lime, after drying this layer twice with painted with clear water, then in the moist state with a thin-flowing glue-plaster solution is painted over until all bumps. are covered, then the dried Surface sanded smooth with sandpaper, then slurried again with thick milk of lime and after this layer has dried it is sanded again with sandpaper. Thereon the wall surface is primed with varnish and given an opaque oil paint, which is also sanded, and finally the wall surface with a Two coats of blackboard lacquer covered with red dividing lines Mistake. Now the finished writing surface is attached to the wall with a: Surrounding frame.
In der Zeichnung ist eine Wandschreibfläche, welche nach dem oben beschriebenen Verfahren hergestellt ist, beispielsweise dargestellt, und zwar zeigt Abb. I dieselbe in Ansicht und Abb.2 im lotrechten Mittelschnitt.In the drawing is a writing surface on the wall, which is facing the top described method is produced, for example shown, namely shows Fig. I the same in view and Fig. 2 in the vertical middle section.
In der Zeichnung bezeichnet I die WandfläChe, 2 die erste Kalkschicht, 3 die Leim-Gips-Schicht, q. die zweite Kalkschicht, 5 den Firnis-, 6 den Ölanstrich, 7 den zweifachen Schultafellacküberzug und 8 den Rahmen.In the drawing, I denotes the wall surface, 2 the first layer of lime, 3 the glue-plaster layer, q. the second layer of lime, 5 the varnish, 6 the oil paint, 7 the double blackboard lacquer coating and 8 the frame.
Die Wandschreibfläche wird für Schulzwecke vorteilhaft so hergestellt, daß an die für die Lehrperson bestimmte unliniierte Schreibfläche a rechts und links entsprechend niedrigere, der Größe der Schüler angepaßte unterteilte Schreibflächen b, b' angeschlossen sind, wie dies aus der Abb. I ersichtlich ist.For school purposes, the writing surface on the wall is advantageously made in such a way that, on the right and left, correspondingly lower, subdivided writing surfaces b, b ' adapted to the size of the pupil are connected to the unlined writing surface a intended for the teacher, as can be seen in Fig.
Das Verfahren kann auch dazu verwendet werden, um gespachtelte Wandflächen herzustellen. Hierbei erhält die Wandfläche zweckmäßig farbige Anstriche nach Wahl.The process can also be used to create smoothed wall surfaces to manufacture. Here, the wall surface is appropriately colored paints of your choice.
