Abstract
PURPOSE:To produce the title concrete product maintaining the excellent surface glossiness over a long period of time by pressing a plastic sheet on the uncured coating film layer formed on the surface of a concrete base material to smooth the surface, curing the layer, and then releasing the sheet. CONSTITUTION:The concrete base material 1 with the surface cleaned is sent in the direction as shown by the arrow A by a delivery roller 5 and backup rollers 9 and 10, a primer 7 is applied from the gap between delivery rollers 6a and 6b and rubbed into the base material 1 with a reverse roller 8 to form an undercoat 2, and then a solventless paint is applied thereon to form an uncured coating film layer 17. A plastic sheet 14 laid over a frame 15 is laminated on the base material 1, the frame 15 is placed on a conveyor belt 2 and sent in the direction as shown by the arrow B, the sheet 14 is pressed by a press roller 16 to smooth the coating film layer 17 which is then cured, the sheet 14 is released, and a coating film layer 3 having >=75 surface glossiness at 60 deg. specular reflection is formed.
