PURPOSE:To obtain a persimmon or zerkova like grain pattern having good appearance, by preparing a coating solution by appropirately mixing an oil urethane solution. CONSTITUTION:An urethane solution being a main material, a curing agent and distilled water are respectively mixed in a ratio of 500:50:150 to prepare a prepared solution. This prepared solution 4 is poured in bottles while the filled bottles are respectively preserved for one day, two days, three days, four days and five days to prepare solutions 4a-4e. When the solution 4 is preserved for 4-5 days and becomes old, elongated gas bubbles are generated in the solution 4. Then, at least three of the solutions 4a-4e are combined to prepare a coating solution 5 which is, in turn, adhered to the surface of a desired article to be coated while flowed out into a water stream flowing to one direction. By this method, the grain is coated and formed by the new solution and wood knot parts are coated and formed by the collapse of gas bubbles generated in the old solution to obtain a grain pattern having persimmon touch of feeling.
