[0116] Step S1200: spraying fluorocarbon topcoat on the target area.
[0117] Below, each step in the method for repairing a damaged paint surface provided by the present disclosure will be described in detail.
[0118] In step S100, the hollow and peeling paint surface on the target area is scraped off to the base layer.
[0119] Specifically, the location of the damaged paint on the wooden structure is determined and the location is identified as the target area. The target area includes the damaged paint and the surrounding area of the damaged paint, so that the repaired paint can be better combined with the surrounding intact paint, thereby improving the reliability and aesthetics of the repaired paint.
[0120] Among them, when hollowing, peeling, cracking, or warping occurs, the paint surface of that part is completely scraped off with tools to expose the surface of the wooden structure, so that the area can be repainted using subsequent processes.
[0121] In step S200, the intact paint surface on the target area is polished and roughened.
[0122] Specifically, the intact paint surface on the target area is polished and roughened so that the target area can have better adhesion during the subsequent painting process. At the same time, the intact paint surface can be thinned to facilitate subsequent painting.
[0123] Among them, fine sandpaper can be used to uniformly polish and roughen the original intact paint surface. The fine sandpaper can be, for example, 360-grit fine sandpaper.
[0124] In step S300, a mixture of kerosene and tung oil is sprayed on the damaged parts of the base layer.
[0125] Specifically, damaged parts of the base layer, such as gaps, are sprayed with a mixture of kerosene and tung oil to prevent internal decay and termites in the wood.
[0126] Among them, a mixture of kerosene and tung oil in a ratio of 1: (1.2-1.8) can be used for spraying on the damaged parts of the base layer, such as 1:1.2, 1:1.3, 1:1.4, 1:1.5, 1:1.6, 1:1.7, 1:1.8, etc., which are not listed here in this disclosure.
[0127] Among them, after mixing kerosene and tung oil and spraying it once and letting it dry, observe whether the surface penetration of the wooden structure is uniform. If it is uneven and incomplete, adjust the proportion of tung oil appropriately according to the penetration situation, such as increasing the proportion of kerosene, and continue spraying until the entire base layer is evenly and thoroughly penetrated.
[0128] In step S410 , it is determined whether there is a gap on the target area. If there is a gap, it is determined whether the width of the gap is greater than 10 mm.
[0129] Specifically, after spraying the damaged parts on the base with a mixture of kerosene and tung oil, it can be determined whether there are large gaps on the target area. If there are large gaps, for example, gaps greater than 10 mm.
[0130] In step S420, if the gap on the target area is larger than 10 mm, the gap is filled with bamboo wood infiltrated tung oil; if the gap on the target area is less than or equal to 10 mm, the gap is smoothed to the base layer with a mixture of tung oil and pig blood putty.
[0131] Specifically, if the gap on the target area is larger than 10mm, the gap can be filled with tung oil soaked in bamboo and wood; if the gap is less than or equal to 10mm, a mixture of tung oil and pig blood putty is used to smooth the gap to the base layer to fill the gap and facilitate the subsequent attachment of other materials.
[0132] Among them, tung oil and pig blood putty in a ratio of 1: (8-10) are mixed to smooth the gap to the base layer, such as 1:8, 1:8.5, 1:9, 1:9.5, 1:10, etc., which are not listed here in this disclosure.
[0133] In step S500, a mixture of tung oil, pig blood putty and coarse brick dust is applied to the damaged part of the base layer.
[0134] Specifically, a mixture of tung oil, pig blood putty and coarse brick ash is used to apply a highly sticky glue-like adhesive on the surface of the wooden components. The putty formed has a high hardness and can completely isolate the air and the wooden structure.
[0135] Among them, a mixture of tung oil, pig blood putty and coarse brick ash in a ratio of 1: (6~8): (1.5~2.5) is applied to the damaged parts of the base layer. When the proportion of tung oil is 1, the proportion of pig blood putty is 6, 6.5, 7, 7.8 or 8, and the proportion of coarse brick ash is 1.5, 2 or 2.5.
[0136] In step S600, a mixture of tung oil, pig blood putty and fine brick ash is applied to the damaged part of the base layer.
[0137] Specifically, a mixture of tung oil, pig blood putty and fine brick ash is then applied to improve the fineness of the mixture and facilitate compaction and leveling; by adding a coarse brick ash mixture as the bottom layer and a fine brick ash mixture as the upper layer, the air and the wooden structure are completely isolated while also facilitating the compaction and leveling of the mixture layer.
[0138] Among them, the particle size of fine brick dust is finer than that of coarse brick dust, that is, when the mixture of tung oil, pig blood putty and brick dust is applied for the second time, the particle size of the brick dust can be finer than that of the first application. The specific particle size is not limited in this disclosure.
[0139] Among them, a mixture of tung oil, pig blood putty and fine brick ash in a ratio of 1: (6-8): (1.5-2.5) is applied to the damaged parts of the base layer. When the proportion of tung oil is 1, the proportion of pig blood putty is 6, 6.5, 7, 7.8 or 8, and the proportion of coarse brick ash is 1.5, 2 or 2.5.
[0140] In step S700, the surface of the damaged part is wrapped with a cambric net, and the cambric net is beaten into the mixture until the cambric net is coated with the pulp.
[0141] Specifically, after applying a mixture of tung oil, pig blood putty and fine brick ash, before drying, wrap the surface of the damaged part with coarse linen mesh, and pat the coarse linen mesh into the mixture of tung oil, pig blood putty and fine brick ash until the mesh of the coarse linen mesh is coated with the pulp, that is, bury the coarse linen mesh in the mixture, further enhancing the strength of the mixture and preventing the mixture putty from cracking.
[0142] In step S800, tung oil and pig blood putty are applied to the target area.
[0143] Specifically, after wrapping the surface of the damaged part with coarse linen net and drying it, tung oil and pig blood putty are applied to the target area to improve the flatness of the surface of the target area and to completely cover the coarse linen net with the pig blood putty.
[0144] Among them, tung oil and pig blood putty are applied on the target area in a ratio of 1: (8-10), such as 1:8, 1:8.5, 1:9, 1:9.5, 1:10, etc., which are not listed here in the present disclosure.
[0145] In step S910, tung oil and pig blood putty are applied to the target area and allowed to dry, and then polished and leveled.
[0146] Specifically, the surface of the damaged part is wrapped with coarse linen net and dried, tung oil and pig blood putty are applied to the target area and dried, and then polished and leveled to level the surface of the target area.
[0147] Among them, coarse sandpaper with 120 mesh to 180 mesh can be used for leveling, such as 120 mesh, 130 mesh, 140 mesh, 150 mesh, 160 mesh, 170 mesh, and 180 mesh, which are not listed one by one in this disclosure.
[0148] In step S920, pig blood putty is used for local repair and leveling.
[0149] Specifically, after sanding and leveling with coarse sandpaper, you can continue to use pig blood putty to perform local repairs and leveling to further improve the surface flatness of the target area.
[0150] In step S930, the pig blood putty is locally repaired and leveled, and then polished and leveled after drying, so that the repaired surface in the target area is flush with the original intact paint surface.
[0151] Specifically, the surface of the target area is continuously polished and leveled using sandpaper so that the repaired surface in the target area is flush with the joint of the original intact paint surface.
[0152] Among them, coarse sandpaper with 120 mesh to 180 mesh can be used for leveling, such as 120 mesh, 130 mesh, 140 mesh, 150 mesh, 160 mesh, 170 mesh, 180 mesh, etc., which are not listed one by one in this disclosure.
[0153] In step S1000 , fluorocarbon primer is sprayed on the target area.
