Description

The present invention relates to a method for producing decorative and / or protective coatings, in particular on wall and / or ceiling surfaces, in which the substrate to be coated is partially coated with a coating agent and another surface layer is applied to the non-coated parts of the substrate becomes.

Furthermore, the present invention also relates to coated substrates, in particular wall and / or ceiling surfaces, with a decorative and / or protective coating, in which the substrate, in particular the wall and / or ceiling surfaces, are partially coated with a coating agent and not coated parts of the substrate another surface layer is applied.

It has long been known to integrate other elements in addition to the coating on wall or ceiling surfaces. For example, plastic parts are applied to the coating at highly stressed areas, for example around light switches and sockets and / or around corners and edges. However, the transition between this plastic part and the coating often causes problems. In addition, there is also an ever increasing need for individual room design, so that not only the protective function of the coating is important, but also increasing demands are made on the optical design of wall and ceiling surfaces, which these incorporated plastic parts do not adequately take into account carry.

The limitation of edge areas is also problematic. The painter is currently using adhesive tape for this. There is a risk of fraying when pulling off. Even with multi-colored wall designs, the surfaces are set against each other with adhesive tape. This procedure does not enable a sophisticated implementation or repeatability.

The present invention is therefore based on the object of providing a process for the production of decorative and / or protective coatings, in particular on wall and / or ceiling surfaces, with which, on the one hand, heavily used surfaces can be effectively protected and on the other hand, coatings with a good optical effect can be produced. A wide variety of design options should be guaranteed to meet the growing demands for individuality in interior design. Finally, the process should be easy and simple to carry out and should enable the use of the coating agents normally used.

Surprisingly, this object is achieved by a method of the type mentioned at the outset, which is characterized in that a metal sheet is used for the other surface layer, the layer thickness of which is between 0.1 times and 5 times the layer thickness of the coating.

The present invention also relates to coated substrates, in particular wall and / or ceiling surfaces, with a decorative and / or protective coating, in which the non-coated ones Parts consist of a metal sheet, the layer thickness of which is between 0.1 and 5 times the layer thickness of the coating.

It is surprising and could not have been foreseen that materials of different types, such as metal and wall paint or plaster, can be combined with one another without any problems and are easy to process. It is also advantageous that the method easily combines a good protective function of heavily used surfaces with an optically appealing design. The labeling, e.g. of parts of the building, and the incorporation of indicative elements, e.g. Direction arrows is possible. Finally, the process opens up a wide variety of design options and thus takes account of the growing need for individuality in interior design too. Edges and corners are particularly worthy of protection in this context.

The method according to the invention is now explained in more detail below.

A wide variety of metal sheets are used as the material for the production of the decorative and protective elements. A wide variety of stainless steel sheets are suitable, for example, which can be highly polished, blasted, ground and / or stained, which can be blasted with braille, which can be color-treated and / or powder-coated and which can have, for example, a hammered surface.
Also suitable are brass and copper sheets, which can also have the most varied of surfaces, for example highly polished, brushed, color-treated, powder-coated and / or gold-plated can have a hammered surface, among other things, aluminum sheets are also suitable, which can also be anodized in all possible anodized colors.

The layer thickness of these metal sheets is matched to the layer thickness of the coating. The layer thickness of the metal sheet is usually between 0.1 times and 5 times the layer thickness of the coating, preferably between 0.5 times and 2 times the layer thickness of the coating. The layer thickness of these metal sheets is preferably matched to the particle size of the filler used in the coating agent or the layer thickness of the coating, i.e. the layer thickness of the metal sheet can approximately correspond to the particle size of the fillers or the layer thickness of the coating. The layer thickness of the metal sheets used is preferably between 0.1 and 5 mm, particularly preferably between 0.5 and 2 mm.

To produce the coating according to the invention, the metal sheet is preferably first cut to the desired shape, possibly bent, folded or kinked. The ornaments or shapes are cut out or punched out from large-sized sheets or from strips (so-called coils). In particular, the desired shapes can be cut out quickly, easily and safely using templates or computer-controlled. For example, corners or protective edges or also individual shapes, for example ring-shaped or angular elements, can be cut out. In addition, a wide variety of ornaments and decorative shapes, such as ribbons, baseboards, etc., can be cut out. For example, metal strips can be cut out to frame doors.

Large protective panels, e.g. for wet areas, e.g. around the sink can be cut or punched out. Furthermore, metal strips can be cut out, which are then attached to wall surfaces at such a height that they provide effective protection against damage caused by pushed back armrests. Furthermore, for example, floor numbers, letters, signage systems and company logos can also be cut out of the metal sheets. There are no limits to the design.

These desired shapes are usually cut out using a special cutting technique.

The cutting is usually done using predetermined shapes or motifs, etc. using laser cutters or guillotine shears. The motifs can be cut freely or scanned using computer-controlled systems. In the case of correspondingly large runs, a punching process can also be carried out using appropriate punches instead of the cutting process. With the aforementioned cutting methods, sharp, but nonetheless injury-free edges are created.

In order to avoid damage and soiling of the metal surface before and during processing and fastening or during the coating of the wall and / or ceiling surfaces, a suitable protective film is preferably applied to the metal parts, which remains open until the wall and / or ceiling surfaces are finished the metal surface remains and only then is removed. The commonly used protective films, for example self-adhesive paper, polyethylene or PVC films, are preferred for this purpose, preferably paper or polyethylene films be used.
Instead of a foil, a lacquer or wax protective layer can also be applied to the metal surface, as is also used, for example, for protecting tools, such as turning tools and milling tools.

The metal element thus protected and cut to the desired shape is then preferably attached to a wall and / or ceiling surface.

The elements are also on other surfaces, such as Wooden components, doors, furniture, etc. transferable. Here too - as described above - a coating is then applied to this substrate.

The metal elements are preferably glued to the solid and load-bearing surface by using commercially available assembly adhesives and, if necessary, by means of aids such as e.g. small nails, screws, dowels and simple clamping devices etc., fixed in their position. For example, with small nails and screws, a back pressure is generated which enables safe positioning. In addition, other fastening options are also conceivable.

The metal parts prepared in this way, possibly provided with a protective film or protective layer, can be attached to a wide variety of locations on the wall and / or ceiling surfaces or other substrates. A preferred application is the protection of switches and / or sockets, in which multifaceted metal sheets are arranged around the switches or sockets. The design-designed metal sheets arranged around the switches or sockets preferably have such a size that the inner surface opening depending on the type of switch (single, double, triple or multiple switch), ie the recess for the switch or for the socket is between 2 and 300 cm² and the outer dimension of this metal sheet is between 5 and 5000 cm². Depending on the desired effect, deviations from this are of course also possible. Also the mounting of ventilation grilles, doorbells, letter boxes, intercoms, operating and display elements of elevators and the like. is possible. Integrated wall and ceiling lights can also be produced in this way. Combinations of different applications are also possible.

In addition, protective edges or protective corners are often used to protect peripheral areas, which can be found in problem areas, e.g. if there is a risk of bumping and contamination, have it stuck on specifically. These corners or protective edges usually have a leg length of 0.5 to 50 cm and a length of 5 to 350 cm.

In addition, a wide variety of signs, such as Cut out name and information signs, number of floors, letters, signposting systems and company logos from the metal sheets and attach them to the wall and / or ceiling surfaces.

A wide variety of ornaments are also possible. For example, the metal sheets can have a wide variety of shapes and various metal sheets can be arranged on a wall and / or ceiling surface, which then form a regular or irregular pattern.

After the metal sheets provided with a protective film the coating agent is applied to the wall and / or ceiling surface.

Suitable coating agents are all conventional (i.e. solvent-containing) and aqueous or water-thinnable coating agents normally used for coating wall and / or ceiling surfaces, such as emulsion paints, mineral paints, silicate paints and / or plasters, solvent-free plasters or emulsion paints being used in particular. Water-thinnable epoxy resins, water-thinnable polyurethane resins, water-thinnable acrylate resins and combinations of various binders are used in particular as binders for these coating compositions. In particular, effect coatings can also be used which, depending on the effect agent, result in colored or achromatic, smooth or plaster-like surfaces.

The colorful effect coatings can be additives of fibers, metal flakes, mica scales, marble and stone granules or plastic chips. Colorful effect coatings are also mainly used on hard-wearing surfaces, e.g. Stairways and hallways. They are usually brushed, rolled or sprayed or with other application tools such as Rubbing board or trowel applied.

Liquid achromatic paints belong to the achromatic group of effect coatings. They are usually rolled or sprayed and give a structure that is very similar to a woodchip wallpaper. Its purpose is to replace the cumbersome gluing and painting of woodchip wallpaper with the one-off process of applying a structural paint.

The effect is achieved through the use of finely divided softwood flours and chips. However, other rich colors can also be applied to give structure.

In addition, a wide variety of emulsion paints and plasters are used. A solvent-free colored stone plaster filled with white and colored natural granules based on an acrylate polymer dispersion is very particularly preferably used in the process according to the invention. This colored stone plaster used with particular preference contains natural granules with a particle diameter of 0.3 to 3 mm. The commercial colored stone plaster Herbol quartzite from Herbol GmbH, Cologne, is used with particular preference.

The layer thickness of this coating is usually between 0.1 and 30 mm, preferably between 0.5 and 5 mm.

If effect coating agents and / or plasters are used to produce the coatings, it is particularly preferred to match the layer thickness of the metal sheet and the particle size of the filler used in the coating agent. This means that the layer thickness of the metal sheet and the particle size of the filler used are approximately the same. This means that fillers with a particle size between 0.1 and 30 mm, preferably between 0.5 and 5 mm, are usually used.

To produce the coating according to the invention, the coating composition is applied, as usual, to the substrates to be processed, in particular wall and / or ceiling surfaces, worked on and smoothed on the previously fastened metal elements. After the coating has dried, the protective film is placed on the metal parts away.

The invention will now be explained in more detail using an exemplary embodiment.

Example 1:

A wall surface is first provided with a commercially available primer (Herbol plaster filler (coating plaster) from Herbol GmbH, Cologne; color c of the color collection N + A, yellow-gray, level 7). An elliptical VA stainless steel sheet (vertical length 12 cm, horizontal width 22 cm) with a layer thickness of 1 mm, which is provided with a self-adhesive paper protection film and which has a circular cutout (diameter 6 cm), is placed on the prepared, dry and stable surface. for a switch element attached to a light switch using a commercially available assembly adhesive (commercial product Uhu® assembly adhesive) and fixed using small blue-headed nails.

A commercially available, solvent-free colored stone plaster filled with white and colored natural granules with 1.2 top grain structure (commercial product Herbol Quarzit®, color Ocean 014, from Herbol GmbH, Cologne) with a dry film layer of approx. 1 is now placed on the wall surface prepared in this way mm applied.

During the drying phase of the colored stone plaster, the protective film applied by the manufacturer of the elements is removed.

At this point, fine reworking of the flush connection of quartzite metal can be carried out.

Even with the combination of such different materials, such as metal and natural stone granulate, a flat surface without shoulders and edges results in uncomplicated processing, whereby the individual components and the design effect of the wall surfaces treated in this way are significantly upgraded. The protective effect of heavily used surfaces is also decisive due to the use of corner protection rails, switch frames, etc.
Labeling, e.g. of parts of the building, and incorporation of informative elements (directional arrows) are also possible.
