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.

彩鋼瓦生銹是一個不容易發現的問題，需要有維護人員經常到屋面進行檢查，保持半年一次的檢查周期比較合理。

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.

彩鋼瓦本身是有使用壽命的，不同質量的彩鋼瓦出現生銹的時間不一樣，同時受到當地環境影響也所不同，根據經驗，國內大部分彩鋼瓦在使用5-10年內容易出現生銹問題。一旦出現閃修或局部生銹時，我們應該盡早進行處理。處理越早越容易，等到全部烤漆脫落，整個彩鋼瓦銹黑，這時就只能更換彩鋼瓦屋面，此時如果再想要進行彩鋼瓦翻新施工已經毫無意義可言了，噴涂明顯的彩鋼瓦翻新專用漆也于事無補了。

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.

那么生銹了怎么處理呢？通常，我們的慣性思維會想，生銹了肯定就是除銹刷漆。但是，除銹刷漆只是基本的步驟。彩鋼板的原漆為烤漆，那么在翻新維護的時候無法采用原有的涂裝工藝，需要使用可施工性比較容易的涂裝方式。既要保證涂料的兼容性，涂膜不脫落，還要具有良好的保護性和裝飾性。所以選什么漆為彩鋼瓦翻新很重要，并不是所有金屬漆都適合彩鋼瓦翻新。這里我們非常推薦使用斯鼎久性好的彩鋼瓦翻新專用漆進行噴涂比較好。

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.

斯鼎耐久型系列彩鋼瓦翻新專用漆根據具體的金屬屋面情況和周邊氣候條件等因素而研制，非常具有針對性，耐久性能好，我們這里推薦給大家，理由是能因地制宜的使用適當的材料進行施工比是比較好的。

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，在進行彩鋼瓦屋面防水、除銹翻新前，要先了解彩鋼瓦漏水、生銹的原因，然后有針對性地提出解決方案。

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.
