Definitions

• the invention relates to a surface coating method for achieving an imitation root wood effect.
• the basic idea of the invention is to use a special spraying technique, contrary to known methods to achieve an imitation coating, which can be implemented in known painting lines.
• a dough glaze dissolved in water is applied by spraying or brushing after applying a filler layer which determines the basic tone of the later imitation layer while briefly venting it.
• a drop or spot spraying of alcohol, isopropanol, acetone, ethyl acetate or the like or an application of salt or coarse salt grains is carried out on the not yet dried dough glaze layer.
• a grain typical of root wood is formed, which is then converted into a paintable state by rapid drying.
• it is then expedient to apply at least one colored clear lacquer layer the coloring being chosen in accordance with the respective natural wood color and emphasizing the plastic character and the special structure of the burl wood.
• a plastic material is assumed, which is first detached briefly on the surface and optionally provided with a primer. After flashing, a filler is applied, whereby the color of the filler determines the basic tone of the later wood imitation.
• the basic tone of the filler is beige.
• a brown, initially paste-like dough glaze is mixed so thinly with a lot of water that there is a throughput time of 12-18 seconds in the DIN cup.
• the dough glaze preparation is essential for the later imitation root wood pattern.
• the prepared dough glaze is then sprayed or spread onto the filler layer.
• gasoline, isopropanol, acetone, ethyl acetate or the like can also be dripped on instead of alcohol or alcohol.
• This structure can be controlled by the amount of alcohol or the like applied and the degree of drying of the dough glaze layer.
• the applied layers are then dried, for example in a continuous oven at 60 ° C. and for about 2 minutes. It has proven to be advantageous that this drying process is carried out quickly and without interruptions.
• a clear lacquer for example a one-component clear lacquer, is colored, i.e. tinted to achieve a further improvement of the imitation wood character.
• a brown dough glaze is applied to the beige filler mentioned and the clear coat is tinted brown.
• any color for example pink, rose red, light to dark blue, yellow, orange or nuances of which can be achieved.
• a metallic, polychrome or opalescent tint has also been successfully tested.
• top layer or the top layers are applied in a manner known per se, with intermediate sanding if necessary.
• the result of this is a quasi-glass-like coating, which overall leads to an appealing external appearance of the objects treated in this way.
• the surface treatment including the application of the water-diluted dough glaze, is carried out in the same way.
• the fresh surface i.e. the dough glaze layer, which has not yet dried, is injected or instilled with gasoline, resulting in a marbled surface.
• a further instillation or metered injection is carried out with alcohol or high-proof alcohol. All other steps then take place analogously to the first exemplary embodiment.
• a water color for example Magiccolour
• Alcohol is then dripped onto the surface which has not yet been dried in this way or is injected with a pipette or other suitable means. In this case too, a wood grain structure is formed.
• the procedure is the same as in the first exemplary embodiment, but instead of alcohol or the like, the not yet dried dough glaze layer is sprinkled with coarse salt.
• an imitation root wood effect is created on or behind glass.
• a glass surface is first cleaned and degreased.
• the cleaned surface is then coated with an adhesive clear coat or transparent adhesion promoter. This coating expediently takes place in a spraying technique known per se.
• the water-soluble dough glaze is applied by brushing or spraying.
• alcohol, spirit, isopropanol, acetone, ethyl acetate or the like is dripped onto the still moist dough glaze, sprayed on in drops or applied at points using a pipette.
• the dough glaze After the dough glaze has dried, it is coated with a colored acrylic glaze. The color of the acrylic glaze is matched to the tint of the dough glaze. Then the dried acrylic glaze layer with a die Color of the primer color determining the root wood imitation layer coated. To protect against damage, the primer layer is covered with protective lacquer. Acrylic lacquer, long oil synthetic resin paint, plastic paint or oil paint are used as protective lacquer.
• a glass plate e.g. for a club table or the like are coated on the back, whereby the advantages of a scratch-resistant surface can be combined with the effect of the imitation wood effect.
