Description

[Technical Field]

[0001] The present invention relates to a method for applying floor markings to the floor of a stadium or the like. [Background technology]

[0002] For sports played in gymnasiums, lines are usually pre-marked on the floor for popular sports. However, the diversification of sports in recent years has created a need for various lines appropriate for each sport. For example, a boccia court is the same size as a badminton court, but if boccia court lines were always painted on a badminton court, it could interfere with badminton play. Drawing lines appropriate for all sports in advance could result in players' judgment being hindered by crossing the floor lines. Furthermore, measuring and redrawing the lines for each game would be time-consuming and cumbersome. Therefore, a method is used in which only the start and end points of the lines are marked in advance, and the marks are then connected with tape or other means before the game begins.

[0003] In such construction, in order to provide a method for painting resin parts that allows masking to be easily applied with simple equipment when creating base color regions and colored regions on the resin part and that allows the base color regions to be formed with excellent appearance quality, a method is known in which masking is applied to the areas of the resin part where the base color is desired to be retained, the areas of the resin part where the color is desired to be colored are primed and colored with a colored paint made of a water-based paint, and the masking is removed to form the base color regions and colored regions, in which the water-based paint is applied and cured to the areas where the base color is desired to be retained, thereby providing a masking that is releasably adhered to the base material and then applying the colored paint (Patent Document 1).

[0012] The present invention has the above-mentioned configuration, and the embodiments of the present invention will be described with reference to the drawings. Note that the drawings are conceptual illustrations of the work, and the thickness of the lines and paint, etc., do not reflect the actual thickness or thickness.

[0013] FIG. 1 is a plan view of a floor board 1 to be additionally painted using the floor marking application method according to the present invention. The surface of the floorboard 1 to be additionally painted shown in Figure 1 is a painted surface 10 that has been coated with a normal polyurethane paint. The process of applying the marking method according to the present invention to this painted surface 10 will be described with reference to the drawings. The polyurethane coating can be applied either as a new full-surface coating or as a restoration after a period of use, and the process is similar in both cases. In order to determine the position where the mark is to be applied, the additional coating position is accurately measured, and then the position and shape of the mark are written on the floor surface 1 by scratching the coated surface 10 and drawing a marking line 20. The area enclosed by the circular line is the enlarged area 11 shown in FIG.

[0014] Figure 2 is an enlarged view of the part surrounded by the circular line in Figure 1. Each of Figures 3 to 8 is a cross-sectional view of the part surrounded by the dashed dotted line in Figure 2, viewed from the direction AA.

[0015] 3, the polyurethane coating is removed from the area surrounded by the marking lines 20 on the coating surface 10. When this process is completed, the state shown in FIG. 4 is obtained.

[0016] In the process shown in Figure 4, the additional paint area 21 exposed by peeling away the polyurethane paint from the area surrounded by the scribed line 20 on the painted surface 10 in Figure 3 is carefully degreased using acetone. If this degreasing process is not carried out, especially when repairs are made after a certain period of use, oil and wax components from aging will remain between the paint and the floor surface, and the additional paint applied later will easily peel off.

[0017] Figure 5 shows the painted surface 10 surrounding the additional paint area 21 that has been exposed by peeling away the polyurethane paint from the area surrounded by the marking line 20, after which masking work has been performed with masking tape 22. This is to prevent the additional paint that will be applied later from adhering to the painted surface 10.

[0018] Figure 6 shows the additional coating area 21 in Figure 5 after a primer coat has been applied. Primer is the first coating applied in a coating process, and because it comes into contact with the base and also with the next coating, its properties can be utilized to allow for fine-tuning of the application. Coating materials with specially strong adhesion to the base are called adhesive primers, and can significantly improve overall adhesion. By applying adhesive primers directly to the base, they have the effect of improving the adhesion of the coating film applied on top of it. As a highly effective primer, it is desirable to use a water-soluble two-component acrylic urethane resin primer 23, as shown in Figure 6.

[0019] After mixing, the water-soluble two-component mixed acrylic urethane resin primer 23 shown in Figure 6 should be applied within the usable time shown in Table 1 below, and then allowed to dry as needed depending on the temperature, humidity, etc., and after confirming that it has hardened, it is desirable to apply a top coat within the time limit for top coating.

[0020] [Table 1]

[0021] FIG. 7 shows the water-soluble two-component mixed acrylic urethane resin primer 23 of FIG. 6 after being top-coated. The top coat is preferably a water-based one-component self-crosslinking reactive floor paint 24 that exhibits strong adhesive strength with the water-soluble two-component mixed acrylic urethane resin primer 23 .

[0022] Figure 8 shows the state after a water-soluble two-component mixed acrylic urethane resin primer 23 has been top-coated with a water-based one-component self-crosslinking reactive floor paint 24, and then the masking tape 22 in Figure 7 has been peeled off, completing the additional coating work.

[0023] FIG. 9 is a plan view of the floorboard 1 after additional painting has been performed using the floor marking method according to the present invention. When viewed from a plan view, marks are drawn on the floorboards 1 by applying a top coat of water-based, one-component, self-crosslinking reactive floor paint 24, making them less likely to peel off.The marks are used as landmarks, and when playing in a game where these marks are used, the court lines can be drawn by connecting the marks with vinyl tape or the like.

[0024] It goes without saying that the present invention is not limited to the structures described in the above-mentioned embodiments, and the embodiments can be modified and changed as appropriate.

[0025] For example, the floor marking method according to the present invention can be applied not only to court lines for sports, but also to painting artwork on the floor.

[0026] Furthermore, the method can be applied not only to floors but also to walls, and due to its strong adhesive strength, the floor marking method of the present invention can be applied to some extent not only indoors but also outdoors. These also fall within the scope of the present invention. [Explanation of symbols]
