Jinan color steel tile renovation construction focuses on rust prevention. During construction, it is suggested to formulate the construction scheme from the perspective of rust prevention effect. Only in this way can we make good project quality.
Before spraying, it is necessary to fully understand the basic situation of the whole color steel tile roof, including but not limited to the current situation of color steel tile, such as the degree of corrosion? If it is only slightly rusted, you can spray one primer and one finish paint or directly use the bottom one color steel tile renovation paint. If the corrosion is serious, we still suggest one bottom and two sides, which is safer.
Here we should note that if your color steel tile is not seriously rusted, but the color steel tile is made of galvanized sheet, we do not recommend the use of bottom integrated paint. Siding has renovated paint for color steel tiles made of galvanized sheet, white iron sheet and other materials, because if these materials use ordinary paint or bottom integrated paint, the fastness of the paint film will be poor.
During construction, the process of grinding and derusting should not be omitted. The renovation, grinding and cleaning of color steel tile is very important. It is best to polish the rusty place until it can expose the metallic luster. The renovation of color steel tile uses the renovated grinding machine equipment of color steel tile, which greatly improves the construction quality. If there is rust, it is not so firmly attached to the surface, which will hinder the combination of primer and substrate surface, thus affecting the fastness of paint film.
During the construction, all processes should be done in place, especially in the grinding and cleaning process. In order to obtain good results, we must not be careless, because we should ensure the close combination of primer and substrate, so as to make the paint film firm, isolate the air and prevent rust. The next coating shall be sprayed after the previous coating is completely dry. If it is not completely dry, blistering is likely to occur because there is water in it.
Some people may add some water into the water-based color steel tile renovation paint. We suggest that if it is too viscous and affects the construction, a small amount of water can be added, not more than 5%. If the water is added too much, the paint will be scrapped.
In short, the renovation construction of color steel tiles should be adjusted to local conditions, and then all links and processes should be in place, and the standard construction is to make specifications.
