Abstract

For coating planar substrates, for example the interior or exterior surfaces of buildings, a substrate (10), which is as flat as possible, is coated with an adhesive layer (12) which supports a planar carrier (16). According to the invention, this is a thin, flat material having in its depth dimension a zone of which the material strength is less than the adhesive strength with respect to the substrate. It is preferred to use a porous, impregnated long-fibre paper, having a thickness in the range of 0.30 to 3.00 mm, especially 0.50 to 0.80 mm, and having a basis weight not below 130 g/m<2>, particularly of bleached cellulose fibres having a length of 2 to 5 mm and a fibre thickness of 10 to 50 mu m. A capillary width in the range of 50 to 150 mu m is also favourable for impregnation with acrylate resin and/or a fungicide. The adhesive layer is a high-viscosity, humidity-insensitive adhesive, for example a pasty, rollable dispersion adhesive made of polyvinyl acetate or acrylate. The carrier (16) adhering to the substrate can simultaneously be an insulating material and can be externally coated, for example with a coat of paint or plaster (22). <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren gemäß dem Oberbegriff von Anspruch 1 und auf die Verwendung dafür benötigter Mittel.The invention relates to a method according to the preamble of claim 1 and to the use of means required therefor.

Die Innen- und Außenflächen von Gebäuden werden auf die verschiedenste Weise behandelt. Üblich ist z.B. das Verputzen mit einem Reibe-, Dekor-, Roll- oder Strukturputz. Für die Raumgestaltung verwendet man vielfach Tapeten, die aus Papier, Gewebe, Jute u.dgl. bestehen und textile oder textilähnliche Beschichtungen tragen können, auch aus strukturierten Kunststoffen.The interior and exterior surfaces of buildings are treated in a variety of ways. It is common e.g. plastering with a grated, decorative, roller or structural plaster. For the interior design one often uses wallpapers made of paper, fabric, jute and the like. exist and can wear textile or textile-like coatings, also made of structured plastics.

Gemeinsam ist allen diesen Belägen oder Beschichtungen, daß sie mit dem Untergrund fest verbunden sind. Die Veränderung ist nützlich und erwünscht, solange der Belag brauchbar bzw. genehm ist; soll bzw. muß er aber gewechselt werden, so kann die Haftung auf dem Untergrund sehr stören. Ein mechanisches Abtragen etwa durch Schaben, Kratzen oder Schleifen ist manchmal unvollkommen, so daß Reste zurückbleiben. Häufig läßt sich eine Beschädigung des Untergrundes nicht vermeiden. Das Entfernen erfordert nicht nur größere Kräfte, sondern beding nicht selten auch eine starke Staubentwicklung. Die notwendigen Arbeiten sind aufwendig und keineswegs umweltfreundlich.It is common to all these coverings or coatings that they are firmly connected to the substrate. The change is useful and desirable as long as the surface is usable or acceptable; if it should or must be changed, however, the liability on the surface can be very disruptive. Mechanical removal, for example by scraping, scratching or grinding, is sometimes incomplete, so that residues remain. Damage to the surface can often not be avoided. Removing not only requires greater forces, it also often causes a lot of dust. The necessary work is complex and in no way environmentally friendly.

Das Auftragen eines Löse- oder Abbeizmittels auf die Beschichtung verlangt häufig noch mechanisches Nacharbeiten. Unangenehm oder sogar gesundheitsschädlich sind Dünste bzw. Dämpfe, die während des Arbeitens eingeatmet werden. Nachteilig ist auch, daß die benutzen Mittel oft nicht bis zum Untergrund vordringen, außer beim Einsatz extrem großer Mengen und nach langer Einwirkung. Das gilt vor allem für verhärtete Strukturen, unlösliche Beschichtungen und Einbettungen unlöslicher Materialien wie Glasgewebe. Neben hohen Kosten können besondere Entsorgungsprobleme entstehen.Applying a solvent or paint remover to the coating often requires mechanical reworking. Uncomfortable or even Vapors or vapors that are inhaled while working are harmful to health. Another disadvantage is that the agents used often do not penetrate to the surface, except when extremely large quantities are used and after a long period of exposure. This applies especially to hardened structures, insoluble coatings and embedding insoluble materials such as glass fabric. In addition to high costs, special disposal problems can arise.

Soweit die vorhandene Beschichtung es erlaubt, kann man sie zwar überspachteln oder verkleiden, doch wird die Beseitigung damit lediglich aufgeschoben und später gewöhnlich nicht nur noch schwieriger, sondern erheblich teurer. Das schlägt besonders zu Buche, wenn aufgrund neuerer Erkenntnisse ein ursprünglich als harmlos angesehener Belag wegen seiner Schädlichkeit entfernt werden muß.As far as the existing coating allows, it can be filled or covered, but the removal is only postponed and later usually not only more difficult, but considerably more expensive. This is particularly noticeable if, based on newer knowledge, a coating originally considered harmless must be removed because of its harmfulness.

Eine aus einem Komplex bestehende Wandverkleidung ist in FR-A-2 133 151 beschrieben. Er wird von zwei Papierbogen gebildet, die untereinander durch eine Polyethylenfolie verbunden sind, wobei der eine aus leicht zu klebendem trägem Papier mit geringem mechanischen Widerstand besteht und der andere von besserer Qualität ist und verziert wird, um die sichtbare Außenseite der Wandverkleidung zu bilden. Hergestellt wird der Komplex in mehreren Verfahrensschritten (Extrudieren, Kalandrieren), wobei das Polyethylen eine Art Klebemittel darstellt, das sich zwischen den beiden Papierbogen befindet und demzufolge einer wasser- und luftundurchlässige Sperrschicht bildet. Der zur Anbringung der Wandverkleidung zu verwendente Kleister ist daher nur bedingt einsetzbar, denn beim Trocknen strebt der unter dem Polyethylen-Träger befindliche Wasserdampf in die Nahtbereiche und behindert dort ein Haften der Wandverkleidung auf dem Untergrund. Ein Nachkleben sämtlicher Kanten ist unumgänglich und zumeist sehr zeitaufwendig. Da die Polyethylenschicht zudem eine Dampfsperre bildet, kann die in der Raumluft enthaltene Luftfeuchtigkeit nicht mehr in die Wände diffundieren. Es kommt häufig zu Schimmelbildung und die Wandverkleidung löst sich ab. Das Wohnklima wird erheblich beeinträchtigt. Probleme ergeben sich ferner bei der Entsorgung der von einer Wand abgelösten Wandverkleidung, denn das mit einer Polyethylenschicht verbundene Papier kann nicht ohne weiteres umweltgerecht recycelt oder beseitigt werden. Eine Anwendung der Wandverkleidung im Außenbereich ist aus den genannten Gründen ebenfalls nicht möglich.A wall covering consisting of a complex is described in FR-A-2 133 151. It is made up of two sheets of paper joined together by a polyethylene film, one made of easy-to-stick, inert paper with little mechanical resistance and the other of better quality and decorated to form the visible outside of the wall covering. The complex is manufactured in several process steps (extrusion, calendering), whereby the polyethylene is a kind of adhesive that is located between the two sheets of paper and consequently forms a water and air impermeable barrier layer. The paste to be used to attach the wall cladding can therefore only be used to a limited extent, because when it dries, the water vapor located under the polyethylene support strives into the seam areas and prevents the wall cladding from adhering to the substrate there. Gluing all the edges is unavoidable and usually very time-consuming. Since the polyethylene layer also forms a vapor barrier, the air moisture contained in the room air can no longer diffuse into the walls. Mold often forms and the wall cladding comes off. The living climate is significantly affected. Problems also arise with the disposal of the wall covering detached from a wall, since the paper connected with a polyethylene layer cannot be easily recycled or disposed of in an environmentally friendly manner. It is also not possible to use the wall cladding outdoors for the reasons mentioned.

Es besteht mithin ein Bedürfnis nach Abhilfe. Aufgabe der Erfindung ist es insbesondere, mit geringstem Aufwand Möglichkeiten zum Aufbringen flacher Dekorationen derart zu schaffen, daß sie auf einfacher Weise abgenommen und entsorgt werden können. Auch schwere Beschichtungen bzw. Beläge sollen zuverlässig befestigbar, aber im Bedarfsfalle dennoch umweltfreundlich abnehmbar sein, namentlich ohne Gesundheitsgefährdung. Ferner bezweckt die Erfindung die Wiederverwendbarkeit zumindest eines Teils der neuartigen Beschichtung und die Weiterverwendbarkeit des gegebenen Untergrundes.There is therefore a need for remedial action. The object of the invention is in particular to create with little effort possibilities for applying flat decorations in such a way that they can be removed and disposed of in a simple manner. Even heavy coatings or coverings should be securely attachable, but still be removed in an environmentally friendly manner if necessary, especially without any health risk. Furthermore, the invention aims at the reusability of at least part of the novel coating and the reusability of the given substrate.

Hauptmerkmale der Erfindung sind im kennzeichnenden Teil von Anspruch 1 angegeben. Ausgestaltungen sind Gegenstand der Ansprüche 2 bis 10.Main features of the invention are set out in the characterizing part of claim 1. Refinements are the subject of claims 2 to 10.

Bei einem Verfahren zum Beschichten flächiger Untergründe, insbesondere zum Aufbringen von Dekorationen auf Innen- oder Außenflächen von Gebäuden, wobei mittels einer Haftschicht auf einem Untergrund ein flächiger dünner Träger angebracht wird, der ein gewünschtes Muster bzw. Färbungen aufweisen oder erhalten kann, sieht die Erfindung vor, daß man als Träger ein poröses, imprägniertes, wasserfestes Langfaser-Papier verwendet, wobei weder die wandseitige noch die äußere Klebeschicht bis in die Mittelzone der Papierstärke eindringt, die somit von Klebemitteln freibleibt, und wobei das Papier in seiner Tiefenabmessung eine Zone aufweist, deren Materialfestigkeit kleiner ist als die Haftfestigkeit auf dem Untergrund. Die beispielsweise mittig im Trägermaterial vorhandene Mittelzone ist integraler Bestandteil des Trägers, aber auch geeignet, sich später von der am Untergrund haftenden Grundschicht trennen zu lassen. Der abgezogene Außenteil kann verworfen oder sogar - zumindest teilweise - wiederverwendet werden, was z.B. bei der Verlegung von Kabeln, Rohrleitungen u.dgl. sehr vorteilhaft sein kann. An der Wand bzw. Decke bleibt lediglich eine dünne, durch den Kleber gehaltene Grundschicht zurück, die mit einem neuen Belag versehen werden kann. Durch die gut luftdurchlässige, aus natürlichem Material bestehende Trägerschicht können Klebstoffe schnell und gut trocknen, so daß selbst in den Nahtbereichen eine optimale Verbindung geschaffen wird. Neben schwach gebundenen Klebern sind auch mineralische Kleber mit sehr hohem Wasseranteil einsetzbar, was für ein späteres Entfernen der nach dem Spaltvorgang auf dem Untergrund verbliebenen Restschichten ohne chemische Hilfsmittel von großem Vorteil ist. Durch die Imprägnierung ist das Auftragen von langsam trocknenden, feuchten Belägen ebenso problemlos möglich, wie die Verwendung des Trägers in Feuchträumen und in Außenbereichen; einer Schimmelbildung wird wirksam vorgebeugt.The invention provides for a method for coating flat substrates, in particular for applying decorations to inside or outside surfaces of buildings, whereby a flat, thin substrate, which can have or receive a desired pattern or color, is attached to a substrate that a porous, impregnated, waterproof long-fiber paper is used as the backing, with neither the wall-side nor the outer adhesive layer penetrating into the central zone of the paper thickness, which thus remains free of adhesives, and the paper having a zone in its depth dimension, whose material strength is less than the adhesive strength on the substrate. The central zone, for example in the center of the carrier material, is an integral part of the carrier, but is also suitable for later separation from the base layer adhering to the substrate. The removed outer part can be discarded or even - at least partially - reused, for example when laying cables, pipes and the like. can be very beneficial. All that remains on the wall or ceiling is a thin base layer, held in place by the adhesive, which can be provided with a new covering. Due to the air-permeable carrier layer made of natural material, adhesives can dry quickly and well, so that an optimal connection is created even in the seam areas. In addition to weakly bonded adhesives, mineral adhesives with a very high water content can also be used, which is a great advantage for later removal of the remaining layers on the substrate after the splitting process without chemical aids. Due to the impregnation, the application of slowly drying, moist coverings is just as easy as that Use of the carrier in damp rooms and outdoors; mold formation is effectively prevented.

Weitere Vorteile beruhen darauf, daß ein Vorbehandeln des Untergrundes nicht mehr erforderlich ist, da die Untergrundbeschaffenheit sehr rauh sein kann. Alte Reibeputze, Löcher oder Risse beispielsweise können mit hochfüllendem Spachtelklebern direkt überarbeitet werden. Auf diese Weise wird in nur einem Arbeitsgang ein spaltbarer, ebener Untergrund geschaffen. Selbst größere Risse werden dauerhaft sicher überbrückt.Further advantages are based on the fact that pretreatment of the substrate is no longer necessary, since the condition of the substrate can be very rough. Old rubbing plasters, holes or cracks, for example, can be reworked directly with high-filling filler adhesive. In this way, a fissile, level surface is created in just one work step. Even larger cracks are permanently bridged safely.

In den Ansprüchen 2 bis 5 sind wesentliche Bemessungen und Vorzugsbereiche für die maßgeblichen Papier-Parameter angegeben. Zur Durchführung des Verfahrens verwendet man laut Anspruch 2 Papier mit einer Stärke im Bereich von 0,30 bis 3,00 mm, vorzugsweise von 0,50 bis 0,80 mm. Solche Papierstärken haben sich im praktischen Einsatz bewährt. Vorzugsweise setzt man gemäß Anspruch 3 Papier mit einem Flächengewicht nicht unter 130 g/m² ein, da spezifisch leichteres Papier eine insgesamt zu geringe Festigkeit aufweist.In the claims 2 to 5 essential dimensions and preferred ranges for the relevant paper parameters are given. According to claim 2, paper with a thickness in the range from 0.30 to 3.00 mm, preferably from 0.50 to 0.80 mm, is used to carry out the method. Such paper thicknesses have proven themselves in practical use. Preferably, according to claim 3, paper with a basis weight of not less than 130 g / m² is used, since specifically lighter paper has an overall too low strength.

Nach Anspruch 4 benutzt man Papier aus gebleichten Cullulosefasern, deren Länge im Bereich von 1 bis 10 mm, vorzugsweise 2 bis 5 mm, und deren Faserstärke im Bereich von 5 bis 100 »m liegt mit solchem Papier wurden besonders gute Testergebnisse erzielt.According to claim 4, paper made from bleached cullulose fibers is used, the length of which is in the range from 1 to 10 mm, preferably 2 to 5 mm, and the fiber thickness is in the range from 5 to 100 »m, and particularly good test results have been achieved with such paper.

Günstig ist die in Anspruch 5 angegebene Verwendung von Papier mit einer Kapillarweite im Bereich von 50 bis 150 »m, damit eine hinreichende Porosität für eine Imprägnierung und für die Verbindung mit einer inneren und/oder äußeren Kleberschicht gegeben ist. Geeignet ist insbesondere wasserfest gebundenes Filterpapier oder Filtervlies.The use of paper with a capillary width in the range from 50 to 150 »m is favorable, so that there is sufficient porosity for impregnation and for connection to an inner and / or outer adhesive layer. Water-proof filter paper or filter fleece is particularly suitable.

Laut Anspruch 6 kann man mit Acrylatharz und/oder einem Fungizid imprägniertes Papier verwenden, um optimale Eigenschaften hinsichtlich der Haltbarkeit zu erzielen.According to claim 6, paper impregnated with acrylic resin and / or a fungicide can be used in order to achieve optimum properties with regard to durability.

Gemäß Anspruch 7 kann die Haftschicht von einem hochviskosen, feuchtikeitsunempfindlichen Kleber gebildet werden, um die Dauerhaftigkeit der Verbindung zu sichern. Speziell kann man laut Anspruch 8 als Kleber einen pastösen, rollfähigen Dispersionskleber verwenden, der z.B.. aus Polyvinylacetat oder Acrylat besteht. Ein solcher Kleber läßt sich mit dem üblichen Methoden und Hilfsmitteln bequem auftragen und gewährleistet die Befestigung des Trägers am Untergrund. Ist diese Befestigung zuverlässig abgelüftet bzw. ausgehärtet, so kann gemäß Anspruch 9 der am Untergrund haftende Träger außen beschichtet werden, z.B. mit einem Anstrich, Putz oder sonstigen Belag, der auf einer Grundierung angebracht wird bzw. von einer mit dem Träger verbundenen äußeren Kleberschicht spannungsfrei gehalten wird.According to claim 7, the adhesive layer can be formed from a highly viscous, moisture-insensitive adhesive in order to ensure the durability of the connection. Specifically, according to claim 8, a pasty, rollable dispersion adhesive can be used as the adhesive, for example. made of polyvinyl acetate or acrylate. Such an adhesive can be conveniently applied with the usual methods and aids and ensures the attachment of the carrier to the substrate. If this fastening is reliably ventilated or hardened, the support adhering to the substrate can be coated on the outside, for example with a coat of paint, plaster or other covering, which is applied to a primer or from an outer adhesive layer connected to the support without tension is held.

Nach Anspruch 10 kann der Träger zugleich ein Dämm- oder Isoliermaterial sein, so daß die aufgebrachte Dekoration einer Wärme- oder Schallübertragung in erwünschter Weise entgegenwirkt. Durch geeignete Materialwahl und Bemessung hat man es in der Hand, die gewünschten Isolier-Eigenschaften herzustellen.According to claim 10, the carrier can also be an insulating or insulating material, so that the decoration applied counteracts heat or sound transmission in a desired manner. With a suitable choice of materials and dimensioning, it is in your hand to produce the desired insulation properties.

Innenseite 14 des Papiers 16 kann der Kleber teilweise eindringen, wie das angedeutet ist. Die Papierstärke im Bereich von 0,30 bis 3,00 mm und das spezifische Flächengewicht von wenigstens 130 g/m² sind so bemessen, daß in der Tiefenabmessung des Trägers 16 ein kleberfreier Bereich vorhanden ist.In the drawing is a - as flat as possible - underground, e.g. a room wall or ceiling, generally designated 10. An adhesive layer 12 is applied to them with a pasty, rollable dispersion adhesive, which holds a long-fiber, preferably impregnated paper 16 as a carrier. The adhesive can partially penetrate into the underside or inside 14 of the paper 16, as is indicated. The paper thickness in the range from 0.30 to 3.00 mm and the specific weight per unit area of at least 130 g / m 2 are dimensioned such that an adhesive-free area is present in the depth dimension of the carrier 16.

An der Ober- bzw. Außenseite 18 des Trägers 16 läßt sich eine Grundierung oder Kleberschicht 20 anbringen, um einen Putz bzw. Aufbau 22 zu befestigen. Auch hierbei ist die Paarung von Papier 16 und Kleber 20 so gewählt und bemessen, daß der Kleber wohl in die Papierporen eindringt, nicht aber bis zu dem inneren Bereich der Papierstärke.A primer or adhesive layer 20 can be attached to the upper or outer side 18 of the carrier 16 in order to fasten a plaster or structure 22. Here, too, the pairing of paper 16 and adhesive 20 is selected and dimensioned such that the adhesive is probably in the paper pores penetrates, but not to the inner area of the paper thickness.

Der beschriebene Aufbau hat die Wirkung, daß der Träger 16 zu beliebiger Zeit gespalten werden kann, um die Beschichtung 22 samt Kleberschicht 20 und Papier-Oberseite 18 zu entfernen. Fig. 2 zeigt den gespaltenen Zustand. Man erkennt, daß die Papier-Unterseite 14 samt Haftschicht 12 auf dem Untergrund 10 zurückbleibt. Diese Grundschicht kann mit einem neuen Belag versehen werden, soferne es nicht notwendig oder erwünscht ist, etwa nach Ausführung bestimmter Montagearbeiten den ursprünglichen Belag wieder anzubringen. Die Neubeschichtung kann in herkömmlicher Klebetechnik erfolgen.The structure described has the effect that the carrier 16 can be split at any time in order to remove the coating 22 together with the adhesive layer 20 and paper top 18. Fig. 2 shows the split state. It can be seen that the underside of paper 14 together with the adhesive layer 12 remains on the substrate 10. This base layer can be provided with a new covering as long as it is not necessary or desirable to re-install the original covering after certain assembly work has been carried out. The new coating can be done using conventional adhesive technology.

Das erfindungsgemäße Verfahren ermöglicht eine Vielzahl von Variationen. In der Praxis geht man so vor, daß der Untergrund 10 fachgerecht so vorbereitet wird, als sollte direkt hierauf verklebt oder geputzt werden. Man bessert also eventuelle Unebenheiten aus und grundiert die gesamte Fläche, um eine gleichmäßige Saugfähigkeit zu erhalten.The method according to the invention enables a large number of variations. In practice, the procedure is such that the substrate 10 is professionally prepared as if it should be glued or cleaned directly thereon. So you can repair any bumps and prime the entire surface to get an even absorbency.

Auf den so vorbereiteten Untergrund 10 wird die Haftschicht 12 aufgetragen. Zweckmäßig benutzt man einen Dispersionskleber z.B. aus Polyvinylacetat oder Acrylat, der unverdünnt und gleichmäßig aufgerollt wird. Kleber mit hoher Viskosität im Bereich von 2 bis 10 Pa·s eignen sich besonders gut. Wichtig ist die Unempfindlichkeit des Klebers gegen Feuchteeinwirkungen, um optimale Klebekraft sicherzustellen und eine Schimmelbildung zu verhindern. Benutzt man wasserarme, schnelltrocknende Kleber mit hoher Anfangshaftung, so kann das Papier 16 mit der Unterseite 14 direkt in das nasse Kleberbett eingedrückt werden. Eine Verarbeitung bei Raumtemperaturen von wenigstens 16 °C läßt sich problemlos durchführen, obgleich solch niedrige Temperaturen wenig günstig sind. Es treten weder Blasen noch eine Schwindung auf, erst recht nicht bei höheren Raumtemperaturen, welche die Trocknung stark begünstigen.The adhesive layer 12 is applied to the substrate 10 prepared in this way. It is advisable to use a dispersion adhesive, for example made of polyvinyl acetate or acrylate, which is rolled up undiluted and evenly. Adhesives with a high viscosity in the range from 2 to 10 Pa · s are particularly suitable. It is important that the adhesive is insensitive to the effects of moisture in order to ensure optimal adhesive strength and to prevent mold growth. If low-water, fast-drying adhesives with high initial adhesion are used, the underside 14 of the paper 16 can be pressed directly into the wet adhesive bed. Processing at room temperatures of at least 16 ° C can be carried out without problems, although such low temperatures are not very favorable. There are no bubbles or shrinkage, especially not at higher room temperatures, which greatly promote drying.

Bevorzugt benutzt man ein Papier aus gebleichten Cellulosefasern mit einer Faserlänge von 2 bis 5 mm und einer Faserstärke von 10 bis 50 »m. Die Papierstärke sollte mindestens 0,20 mm betragen, damit eine genügende Festigkeit sichergestellt ist. Andererseits wird eine Porenweite von 50 bis 150 »m bevorzugt, um eine dauerhafte Verbindung mit den Klebeschichten 12, 20 zu ermöglichen. Hervorragend eignet sich wasserfest gebundenes Filterpapier oder Filtervlies. In einer Anstrichfarbe sorgt die Teilchengröße eines Füllstoffs, z.B. Quarz, von wenigstens 100 »m dafür, daß der Anstrich an der Oberfläche 18 des Papiers 16 gut haftet, aber nicht bis in die erwähnte Mittelzone eindringt.It is preferred to use a paper made from bleached cellulose fibers with a fiber length of 2 to 5 mm and a fiber thickness of 10 to 50 »m. The paper thickness should be at least 0.20 mm to ensure sufficient strength. On the other hand, a pore size of 50 to 150 »m is preferred in order to enable a permanent connection with the adhesive layers 12, 20. Water-proof filter paper or filter fleece is ideally suited. In a paint, the particle size of a filler, e.g. Quartz, at least 100 »m, so that the paint adheres well to the surface 18 of the paper 16, but does not penetrate into the middle zone mentioned.

Sehr vorteilhaft ist ein Acrylatharz-Bindemittel, wie es auch in den zum nachfolgenden Anstrich verwendeten Farben vielfach enthalten ist. Sowohl bei der Haftung als auch der übrigen Eigenschaften ergibt sich dadurch eine besonders gute Verbindung mit der Grundierung bzw. Kleberschicht 20, die nach genügendem Ablüften bzw. Aushärten der Haftschicht 12 auf das Papier 16 aufgetragen werden kann. Ist dieser Auftrag 20 extrem wasserarm, so ergibt sich eine genügend hohe Klebkraft, um auch sehr schwere Beläge wie Putz, Fliesen o.dgl. zuverlässig zu tragen. Eine Imprägnierung des Trägers 16 mit Acrylatharz vermittelt die notwendige Wasserfestigkeit, die den Zusammenhalt des Papiers 16 auch dann gewährleistet, wenn es aufgrund einer stärkeren Putzschicht 22 längere Zeit der Feuchtigkeit ausgesetzt ist.An acrylic resin binder, as it is often contained in the colors used for subsequent painting, is very advantageous. Both in terms of adhesion and of the other properties, this results in a particularly good connection with the primer or adhesive layer 20, which can be applied to the paper 16 after the adhesive layer 12 has been adequately vented or hardened. If this order 20 is extremely low in water, there is a sufficiently high adhesive strength to cover even very heavy coverings such as plaster, tiles or the like. reliable to wear. Impregnation of the carrier 16 with acrylic resin provides the necessary water resistance, which ensures the cohesion of the paper 16 even when it is exposed to moisture for a long time due to a thicker plaster layer 22.

Das Papier 16 kann mit einem Fungizid schimmelhemmend ausgerüstet werden. Für besondere Fälle ist es auch möglich, das Material flammhemmend auszurüsten. Die Dampfdiffusion wird durch solche Zusätze nicht beeinträchtigt.The paper 16 can be equipped with a fungicide to prevent mold. For special cases, it is also possible to provide the material with a flame-retardant finish. The vapor diffusion is not affected by such additives.

Man erkennt, daß zum Beschichten flächiger Untergründe, z.B. der Innen- oder Außenflächen von Gebäuden, auf einem möglichst ebenen Untergrund 10 eine Haftschicht 12 aufgebracht wird, die erfindungsgemäß einen flächigen Träger 16 haltert, nämlich ein dünnes Flachmaterial, das in seiner Tiefenabmessung eine Zone aufweist, deren Materialfestigkeit kleiner ist als die Haftfestigkeit auf dem Untergrund. Bevorzugt verwendet man ein poröses, imprägniertes Langfaser-Papier mit einer Stärke im Bereich von 0,30 bis 3,00 mm, insbesondere 0,50 bis 0,80 mm, und mit einem Flächengewicht nicht unter 130 g/m², namentlich aus gebleichten Cellulosefasern mit einer Länge von 2 bis 5 mm und einer Faserstärke von 10 bis 50 »m. Eine Kapillarweite im Bereich von 50 bis 150 »m ist günstig, auch zum Imprägnieren mit Acrylatharz und/oder einem Fungizid. Als Haftschicht dient ein hochviskoser, feuchtigkeitsunempfindlicher Kleber, z.B. ein pastoser, rollfähiger Dispersionskleber aus Polyvinylacetat oder Acrylat. Der am Untergrund haftende Träger 16 kann zugleich ein Dämm- oder Isoliermaterial sein und außen z.B. mit einem Anstrich oder Putz 22 beschichtet werden.It can be seen that for coating flat surfaces, for example the inner or outer surfaces of buildings, an adhesive layer 12 is applied to a surface 10 that is as flat as possible, which according to the invention holds a flat carrier 16, namely a thin flat material that has a zone in its depth dimension whose material strength is less than the adhesive strength on the ground. It is preferred to use a porous, impregnated long fiber paper with a thickness in the range from 0.30 to 3.00 mm, in particular 0.50 to 0.80 mm, and with a weight per unit area not less than 130 g / m², especially made from bleached cellulose fibers with a length of 2 to 5 mm and a fiber thickness of 10 to 50 »m. A capillary width in the range of 50 to 150 »m is favorable, also for impregnation with acrylic resin and / or a fungicide. A highly viscous, moisture-insensitive adhesive serves as an adhesive layer, for example a pasty, rollable dispersion adhesive made of polyvinyl acetate or acrylate. The carrier 16 adhering to the substrate can also be an insulating or insulating material and can be coated on the outside, for example with a paint or plaster 22.
