The color steel tile workshop is mainly a steel structure building. The roof waterproof is made up of the rigidity of the color steel tile and self waterproof. It is mainly based on drainage and supplemented by waterproof. There is no systematic waterproof layer on the roof. When the color steel tile is subject to temperature difference, expansion, deformation and loosening, it is easy to cause the color steel tile to leak in stormy weather, so it is often necessary to renovate the color steel tile roof. This special structure is the main cause of water leakage of color steel tile. The rust of the color steel tile is mainly caused by the damage of ultraviolet rays to the protective paint on the surface of the color steel tile, so that the metal part of the color steel tile is connected with the external air and moisture, resulting in chemical oxidation. If the rust is not treated for a long time, it is easy to rust and puncture the color steel tile, and it may also cause water leakage. Therefore, we need to often check the roof and choose to renovate the durable color steel tile with special paint after finding problems, so as to save money and trouble.

彩钢瓦生锈是一个不容易发现的问题，需要有维护人员经常到屋面进行检查，保持半年一次的检查周期比较合理。

The rust of color steel tile is a problem that is not easy to find. Maintenance personnel need to check the roof frequently, and the inspection cycle of half a year is reasonable.

彩钢瓦本身是有使用寿命的，不同质量的彩钢瓦出现生锈的时间不一样，同时受到当地环境影响也所不同，根据经验，国内大部分彩钢瓦在使用5-10年内容易出现生锈问题。一旦出现闪修或局部生锈时，我们应该尽早进行处理。处理越早越容易，等到全部烤漆脱落，整个彩钢瓦锈黑，这时就只能更换彩钢瓦屋面，此时如果再想要进行彩钢瓦翻新施工已经毫无意义可言了，喷涂任何的彩钢瓦翻新专用漆也于事无补了。

Colored steel tiles have a service life. The time of rust of colored steel tiles of different quality is different, and they are also affected by the local environment. According to experience, most domestic colored steel tiles are prone to rust within 5-10 years of use. In case of flash repair or local rust, we should deal with it as soon as possible. The earlier the treatment, the easier it is. When all the baking paint falls off and the whole color steel tile rusts black, the roof can only be replaced. At this time, if you want to carry out the color steel tile renovation construction again, it is meaningless, and spraying any special paint for color steel tile renovation is useless.

那么生锈了怎么处理呢？通常，我们的惯性思维会想，生锈了肯定就是除锈刷漆。但是，除锈刷漆只是基本的步骤。彩钢板的原漆为烤漆，那么在翻新维护的时候无法采用原有的涂装工艺，需要使用可施工性比较容易的涂装方式。既要保证涂料的兼容性，涂膜不脱落，还要具有良好的保护性和装饰性。所以选什么漆为彩钢瓦翻新很重要，并不是所有金属漆都适合彩钢瓦翻新。这里我们特别推荐使用斯鼎久性好的彩钢瓦翻新专用漆进行喷涂比较好。

So how to deal with rust? Usually, our habitual thinking will think that rust must be derusting and painting. However, derusting and painting are only basic steps. The original paint of color steel plate is baking paint, so the original coating process cannot be used during renovation and maintenance, and the coating method with easy constructability needs to be used. It is necessary to ensure the compatibility of the coating and the film does not fall off, but also have good protection and decoration. Therefore, it is very important to choose what paint for the renovation of color steel tiles. Not all metallic paints are suitable for the renovation of color steel tiles. Here, we especially recommend to use the special paint for renovation of color steel tiles with good durability for spraying.

斯鼎耐久型系列彩钢瓦翻新专用漆根据具体的金属屋面情况和周边气候条件等因素而研制，非常具有针对性，耐久性能好，我们这里推荐给大家，理由是能因地制宜的使用适当的材料进行施工比是比较好的。

Siding durable series special paint for color steel tile renovation is developed according to the specific metal roof conditions and surrounding climatic conditions. It is very targeted and has good durability. We recommend it to you here because it is better to use appropriate materials according to local conditions.

因此，在进行彩钢瓦屋面防水、除锈翻新前，要先了解彩钢瓦漏水、生锈的原因，然后有针对性地提出解决方案。

Therefore, before the waterproof and derusting renovation of color steel tile roof, we should first understand the causes of water leakage and rust of color steel tile, and then put forward targeted solutions.
