Abstract

To create an individual and artistic image on a large surface, e.g. a wall or ceiling and especially at buildings, the surface (2) is coated (3) with a material which can be hardened and set, and is polished where the image is to be made. When the coating has fully set, flexible frame sections for elements (5,6) of the image (1) are fitted temporarily on the coating. The zones flanking the outside of the fitted frame sections are coated with a material which can be hardened, and in a thickness matching the frame thickness, or projecting over the frame level. When the top coating has set, the frame sections are removed mechanically. The outer coating is a colored plaster. If the design is for a floor surface, the whole surface area is covered by a protective coating against wear.

Description

The invention relates to a method for producing individually and artistically designed pictorial representations on wall or ceiling surfaces in particular of buildings, the wall or ceiling surfaces with a can be provided with a curable coating.

Due to the great need for aesthetically more effective individual Design of preferably outer surfaces of buildings are already Process for generating visual representations on wall or Ceiling surfaces of buildings known in different configurations. So it has long been customary to make handmade on wall or ceiling surfaces Apply paintings using suitable colors with a brush (so-called facade painting). However, this involves considerable effort, in particular takes a lot of time and the durability is quite limited. Especially under rainy and longer lasting winter conditions climatic conditions is the liability of the picture elements or colors unsatisfactory depending on the materials used. Is also one of Cleaning required from time to time, e.g. B. using a high pressure water jet in the case of representations that are not easily accessible manually, extremely problematic due to the expected destruction of the image.

To improve the durability of corresponding pictorial representations it is also known in practice to have fired surface parts provided with image parts and to fix glazed tiles to wall or ceiling surfaces in such a way that the picture parts of the tiles complement each other to form an overall picture. Such visual representations, however, require a considerably larger one Production effort. In addition, the pictorial design, e.g. B. the adjustment to concrete location and lighting conditions, the variation of details etc., due to the production technology of the tiles at the place of installation is no longer possible.

In addition to the above-mentioned known state of the art, DE 35 35 398 A1 using a method of forming a decorative layer on a base Relief structure known, with a part of the underlay surface Primer to fill in the depressions on the surface of the underlay is applied. Then an ink or a coat of paint printed or applied, which is different in color from the surface the document differs. This process will certainly improve the quality of the facade painting, but can not be worth mentioning Contribute to the weatherproof durability improvement in particular.

From DE 43 38 929 A1 is also a process for the production of decorative and / or protective coatings, especially on wall and / or Known ceiling surfaces, after that with a removable protective film provided sheet metal parts attached to a base layer, then one Coating layer applied and then after drying the Protective film of the sheet metal part to develop its optical effectiveness Will get removed. However, this known method of making is more pictorial Representations not intended and unsuitable.

According to DE 297 10 296 U1 there is also a template for production of decorative, overlying ornaments, especially on wall and Known ceiling areas. Then the surface to be coated is / are to be coated one or more stencil shapes placed and a coating agent in them introduced, which after removal of the template Ornament results. This way of working is for the production of individual and artistically designed visual representations not suitable, because of the stencils just a repetitive representation of the same ornament is possible in the sense of a simple figurative representation.

In view of the disadvantages of the known prior art, the invention lies based on the task of a method of manufacturing individually and artistically designed visual representations of the above To provide a type which, with simple technology, provides fast, effective and yet individual image design, even more artistic Allows claims with high optical-aesthetic effectiveness, where excellent weather-resistant liability and durability guaranteed is.

This object is achieved in that the coating is smoothed in the area of the intended visual representation that after fully or partially hardened coating flexible frame parts for elements of the visual representation temporarily on the coating be applied that then delimited by frame parts Surface areas a curable coating material in one of the Thickness of the frame parts corresponding or greater thickness with one of the coating has a different surface structure, and that continues after partial or complete curing of the coating material the frame parts are mechanically detached from the coating.

The advantages of the invention are in particular the possibility of individual and also figuratively designed with increased artistic demands Presentations quickly and effectively using a comparatively simple, Technology suitable for construction sites on wall or ceiling surfaces to install. Each picture part or element can be individual and artistic designed and / or varied and the specific local conditions and ideas be adjusted, with subsequent image changes by simple Changing the position / shape of the flexible frame parts are possible.

The process allows the use of weather-resistant coating materials, so that even under particularly unfavorable climatic conditions good durability is guaranteed. This also applies to the application of hydraulic and / or mechanical cleaning processes without the risk of image damage.

The visual representation raised above the wall or ceiling surface created together with the special surface structure of the image parts or elements make a special visual and aesthetic impression on the Viewer. In particular, a quasi-three-dimensional representation is created with different impressions from different angles.

The application of the method according to the invention for structural plaster painting or for structural plaster graphic design advantageously allows both a generation of decorative images as well as predominantly Information mediating advertising space designs, information signs u. Like. On walls or ceilings of houses and other structures.

In an advantageous and expedient embodiment of the invention with regard to The coating material consists of durability and optical effect in a first Variant made of cement-based colored stone plaster or in a second variant from a resin-bound plaster.

The coating material expediently contains, of course, colored fillers Stone granules in their natural colors, to choose from too generate colored effects of the visual representation. To achieve a Desired surface structure are structuring the coating material Fillers are added and / or the surface structure is replaced by appropriate mechanical processing when applying the coating material or after partial or complete curing. To achieve of special surface effects of the image display are advantageous the coating material effect, especially refractive and / or reflective fillers, such as metal splinters, mica parts, Plastic or glass particles, added. Possibly. in connection with a special artificial lighting of the pictorial representation can be on achieve excellent optical effects in this way.

It was found to be particularly favorable that the strength of the applied cured layer of coating material preferably in the area between 1 mm and 6 mm.

In a further expedient embodiment of the method according to the invention individual areas or elements of the visual representation after the coating material has hardened a special surface treatment subjected, in particular ground and optionally polished, to highlight parts of the picture. This can, for example certain motifs and / or information of the representation are weighted.

Appropriately, the flexible frame parts for elements of the pictorial Representation from adhesive strips. In particular to delimit areas with several identical motifs of the pictorial representation are favorably used the motif-bearing templates as frame parts.

Another embodiment of the invention is characterized by the Use on ceiling surfaces designed as floor surfaces, whereby the pictorial representation for the protection and security of the floor accessibility by applying a protective layer, in particular an epoxy resin layer is sealed.

In a further advantageous embodiment, the method is also three-dimensional pictorial representations applicable.

A sunflower was chosen as an example of a graphic representation 1, which are arranged on the wall surface 2 of a building, not shown is (Fig. 1 and 2).

The wall surface 2 consists, for example, of a brick wall, which with a curable coating 3 is provided. This coating was used 3 from a common exterior plaster made of lime cement mortar (1 part Lime: 1 part cement: 6 parts sand of appropriate grain).

In the area of the proposed arrangement of the graphic representation 1, the curable coating 3 first rubbed smooth with a float. Subsequently, after partial or complete curing, the visual Representation 1 in its outline on the coating 3 using a suitable drawing material drawn by hand. Now be flexible Frame parts 4, in the example consisting of adhesive strips, so immediately next to the lines of the drawing glued to the coating 3 that the flexible frame parts 4 corresponding to the picture elements 5, 6 ... area areas 7, 8 ... delimit the graphic representation 1 (see FIG. 3). However, it is also possible, the flexible frame parts 4 without using one on the coated Wall surface 2 pre-made hand drawing directly on the Apply coating 3.

The execution and temporary attachment option of the flexible Frame parts 4 allow an individual artistic design of the pictorial Representation 1, a variation of individual picture elements 5, 6 ... in the sense of a Optimization and Like. by the flexible frame parts 4 slightly accordingly deformed and can be changed in their positional arrangement.

Then the correspondingly delimited surface areas 7, 8 ... a hardenable coating material 9, in the example a cement-containing colored stone plaster, applied and against the thickness of the flexible frame parts 4 / adhesive strips rubbed (see Fig. 4). Accordingly, one arises with the coating 3 surface connected, raised against the coated wall surface 2 formed picture element 5, 6 .... Each or some of the picture elements 5, 6 ... have a surface structure that differs from the surface structure of the Coating 3 differs. This is for the picture element 6 from FIGS. 2 and 4 clearly visible. The corresponding surface structure can be Addition of structuring fillers and / or by mechanical Processing after partial or complete hardening of the covering material 9 can be achieved. 9 colored fillers can also be or aggregates (e.g. stone granules) as well as refractive or reflective Fillers or additives, such as metal splinters, glass particles and the like. Like. added to achieve special optical effects of individual picture elements 5, 6 ... or to achieve the entire graphic representation 1.

The thickness of the layer of coating material 9 is after curing approx. 3 - 5 mm. This measure corresponds to the survey of the individual picture elements 5, 6 ... opposite the coated wall surface 2.

After partial or complete curing of the coating material 9 can the flexible frame parts 4 / adhesive strips without damaging the edges the picture elements 5, 6 ... are removed. Now, through cleaning and others if necessary rework a completion of the graphic representation 1 done. If desired, individual areas can be created 7, 8 ... or picture elements 5, 6 ... a special surface treatment be subjected. Surface areas 7, 8 ... can be ground and can be optionally polished to make assigned motifs / representations look special emphasized.

The invention is not by the details of the above-described embodiment limited. In particular, in addition to the application to structural plaster painting also the structural plaster graphic design for both aesthetic as well as advantageous for informative purposes. Of course the top surfaces of ceiling surfaces, i.e. H. Floor surfaces, encompassed by the method according to the invention, being as floor surfaces executed ceiling surfaces are sealed by applying a protective layer. Thus, the visual representation is effective before removal / wear u. like. protected. The use of an eposide resin layer has been particularly successful proven.

The application of the method to three-dimensional visual representations is easily possible using suitable process technology.
