铁艺大门，以其独特的造型与坚固的质感，成为庭院、宅邸的一道风景线。然而，历经风吹日晒雨淋，表面涂层难免出现脱落，不仅影响美观，还可能加速铁艺生锈腐蚀。当铁艺大门出现涂层脱落时，别担心，通过科学的修复方法，能让它重焕光彩，继续守护一方景致。

　　The wrought iron gate, with its unique design and sturdy texture, has become a scenic spot in courtyards and mansions. However, after exposure to wind, sun, and rain, the surface coating is inevitably peeled off, which not only affects its appearance but may also accelerate the rusting and corrosion of the iron. When the coating on the wrought iron gate falls off, don't worry. Through scientific repair methods, it can regain its shine and continue to protect the scenery.

　　修复前，需先对脱落涂层的区域进行全面清理。涂层脱落往往伴随着锈迹的产生，使用钢丝刷、砂纸等工具，仔细打磨脱落部位及其周边区域。对于较厚的锈层，先用钢丝刷用力刷除，再用砂纸进行精细打磨，将表面打磨至平整光滑，露出铁艺原本的金属光泽。在打磨过程中，要注意力度均匀，避免对铁艺造成过度损伤。若锈迹较为顽固，还可借助除锈剂，将除锈剂均匀涂抹在生锈部位，等待片刻，待锈迹与除锈剂充分反应后，再用清水冲洗干净，并用干净的布擦干水分，确保修复区域干燥清洁，为后续的涂层修复打好基础。

　　Before repairing, it is necessary to thoroughly clean the area where the coating has peeled off. Coating detachment is often accompanied by the formation of rust. Use tools such as wire brushes and sandpaper to carefully polish the detached area and its surrounding areas. For thicker rust layers, first use a wire brush to vigorously remove them, and then use sandpaper to finely polish the surface until it is flat and smooth, revealing the original metallic luster of the iron. During the polishing process, attention should be paid to uniform force to avoid excessive damage to the iron. If the rust is stubborn, you can also use rust remover to evenly apply the rust remover to the rusted area, wait for a moment, wait for the rust to fully react with the rust remover, then rinse it clean with water and dry it with a clean cloth to ensure that the repair area is dry and clean, laying a foundation for subsequent coating repairs.

　　清理工作完成后，要选择合适的底漆进行涂刷。底漆如同涂层的 “根基”，起到防锈和增强附着力的作用。根据铁艺大门的材质和使用环境，可选用环氧底漆、醇酸底漆等。在涂刷底漆前，先将底漆充分搅拌均匀，确保成分混合一致。使用毛刷或滚筒，沿着铁艺的纹理方向，均匀地将底漆涂刷在修复区域。涂刷时要注意厚度适中，避免出现流坠、漏刷等情况。一般来说，底漆需要涂刷 1 - 2 遍，每遍之间要等待足够的干燥时间，通常按照产品说明书的要求，待上一遍底漆完全干燥后，再进行下一遍涂刷。干燥过程中，要避免灰尘、杂物附着在底漆表面，影响底漆效果。

　　After the cleaning work is completed, it is necessary to choose a suitable primer for painting. Primer is like the "foundation" of a coating, playing a role in rust prevention and enhancing adhesion. According to the material and usage environment of the wrought iron gate, epoxy primer, alkyd primer, etc. can be selected. Before applying the primer, mix it thoroughly and ensure that the ingredients are evenly mixed. Use a brush or roller to evenly apply the primer along the texture direction of the wrought iron in the repair area. When painting, pay attention to the appropriate thickness to avoid situations such as sagging and missed brushing. Generally speaking, the primer needs to be applied 1-2 times, and sufficient drying time should be allowed between each coat. Usually, according to the product manual, the next coat should be applied after the previous coat of primer is completely dry. During the drying process, it is important to avoid dust and debris from adhering to the surface of the primer, which can affect its effectiveness.

　　底漆干燥后，就可以进行面漆的涂装了。面漆的选择丰富多样，可根据个人喜好和整体装修风格，挑选不同颜色和质感的涂料，如哑光漆、亮光漆等。同样在涂装前将面漆搅拌均匀，为保证涂装效果，可采用喷涂或刷涂的方式。若采用喷涂，需使用专业的喷漆设备，调整好喷枪与铁艺大门的距离和角度，保持匀速移动，使面漆均匀覆盖在底漆表面；若选择刷涂，要用优质的毛刷，从一个方向进行涂刷，尽量减少刷痕。面漆一般需要涂刷 2 - 3 遍，每遍之间等待面漆干燥，随着面漆的层层叠加，铁艺大门的色彩和光泽会逐渐呈现出来，达到理想的视觉效果。

　　After the primer dries, the topcoat can be applied. There is a wide variety of options for topcoats, and different colors and textures of coatings can be selected according to personal preferences and overall decoration styles, such as matte paint, glossy paint, etc. Before painting, stir the topcoat evenly. To ensure the painting effect, spraying or brushing can be used. If spraying is used, professional spraying equipment should be used to adjust the distance and angle between the spray gun and the iron gate, maintain a constant speed of movement, and ensure that the topcoat covers the surface of the primer evenly; If you choose to brush, use a high-quality brush to brush from one direction and minimize brush marks as much as possible. The topcoat usually needs to be applied 2-3 times, waiting for the topcoat to dry between each coat. As the layers of topcoat stack, the color and luster of the wrought iron gate will gradually appear, achieving the ideal visual effect.

　　除了对脱落区域进行修复，为了延长铁艺大门涂层的使用寿命，还可对整个大门进行防护处理。待面漆完全干燥后，可在表面涂刷一层清漆或防护蜡。清漆能形成一层透明的保护膜，增强涂层的耐磨性和抗污性；防护蜡则可以在铁艺表面形成一层蜡膜，起到防水、防氧化的作用。涂抹防护蜡时，用干净的软布蘸取适量蜡，均匀地擦拭在大门表面，然后用另一块干净的软布进行抛光，使大门表面更加光亮。

　　In addition to repairing the detached area, in order to extend the service life of the iron gate coating, the entire gate can also be protected. After the topcoat is completely dry, a layer of clear varnish or protective wax can be applied to the surface. Clear varnish can form a transparent protective film, enhancing the wear resistance and stain resistance of the coating; Protective wax can form a wax film on the surface of iron, which plays a role in waterproofing and oxidation prevention. When applying protective wax, dip a clean soft cloth in an appropriate amount of wax, evenly wipe it on the surface of the door, and then polish it with another clean soft cloth to make the surface of the door brighter.
