How many years can the color steel tile refurbished paint last? What paint is used for the renovatio

In recent years, there are more and more workshops built with steel structures and color steel tiles, and after a long service life, the steel structure and color steel tile roofs will be corroded. If the corrosion condition is not maintained and refurbished in time, there will be varying degrees of property losses.

In the absence of corrosives, remove man-made damage factors, and the product quality is good, the service life of color steel tile rust removal and renovation can reach about 20 years.

It is inseparable from various factors such as the service life of its own color steel tile and the anti-corrosion life of the special paint for the renovation of the selected color steel tile.

Color steel tile rust removal and renovation steps:

Special equipment is used for grinding and rust removal or sandblasting and rust removal, and there shall be no rust spots in the base layer after rust removal, and oil, grease, dust, iron sand and metal oxides shall be cleaned up.

Before the spraying process, in case of rain or other conditions that cause the surface of the matrix steel to be wet, it is necessary to wait for the environment to reach the construction conditions, and then remove the rust after drying the surface moisture with dry compressed air;

The surface of the steel after rust removal reaches the derusting grade, and the surface is cleaned before the next process can be carried out, and the surface of the steel after the rust removal is qualified shows a metallic luster.

If the rust has been returned before the primer, re-polishing and rust removal or sandblasting rust removal, do not reduce the abrasive requirements to avoid reducing the roughness.

In our daily life, when decorating, we will see that there are all kinds of tiles, among which there is a common tile glue color steel tile, so when the color steel tile is renovated, what paint do we need to use?

1. If the color steel tile is to be renovated, then paint can generally be used, but the smell will generally be greater after renovation, and the renovation effect will be relatively poor. Now most friends will choose to use water-based paint specially used to renovate color steel tiles to renovate color steel tiles.

2. The water-based paint specially used to renovate the color steel tile is not only environmentally friendly, but also the renovation effect will be much better than the renovation effect of the paint, and the smell will not be so big, but it will be more expensive. What paint does the customer need to use to renovate the color steel tile, and generally needs to choose according to the actual corrosion degree and area of the color steel tile, and the economic ability of self-defeating.

3. Before renovating the color steel tile, you must first clean up the dust and sundries on the surface of the color steel tile, and then use a wire brush and abrasive cloth to polish the rust on the surface of the color steel tile, and then use a clean rag to clean up the floating dust on the surface of the color steel tile, and then start painting construction.

4. Under normal circumstances, when the Bureau of Destruction is refurbishing the color steel tile, it is best to carry out the topcoat spraying construction twice, and the primer of the color steel tile should be covered when spraying the topcoat. If you can still see the primer after the topcoat has been sprayed, then it means that the topcoat has been sprayed too thinly.

5. If the topcoat is sprayed too thinly, the sealing of the surface of the color steel tile will become poor, and it will be easy to enter the water, which will lead to the oxidation of the color steel tile and the phenomenon of rust. Therefore, when spraying the topcoat, you must spray the topcoat thicker and more carefully, or start to spray the thinner part from the opposite direction, so that the refurbishment quality and effect of the color steel tile can meet the standard.

After rinsing, the corroded color steel tile will have local water leakage, we need to waterproof, fill the leakage, and cooperate with the reinforced polyester cloth for waterproof construction. 3. After the completion of the above two steps, the first spraying of rust fixing agent (function: anti-aging, high temperature resistance, cold resistance, strong adhesion, strong anti-corrosion and anti-rust ability) is non-toxic, harmless, green and energy-saving.

4. After the rust fixing agent is dried, spray the water-based paint (matte water-based paint) for the second time. 5. In the last step, after the second time is completely dry, spray the third water-based paint sock spine blind (bright water-based paint).

In many large buildings or factories often use color steel tiles on the roof, because the color steel tiles are mainly made of thermoplastic spraying, although there are many advantages, but can not withstand the erosion of acid and alkali, it is easy to appear aging after a long time, paint film pulverization and other phenomena.

It is recommended to brush SD-CW308 primer once first, which is conducive to improving the basic adhesion and making the topcoat more saturated. Then apply two layers of paint to maximize the effect of the paint and extend the service life.

Second, the color steel tile renovation precautions.

1. Renovate in time.

If the color steel tile comes into contact with the type trembling acid, alkali, etc., it will produce a chemical reaction and produce rust, and it is very likely that there will be serious rust and perforation after a long time.

After sanding, do a good job of waterproof measures, if there are any loopholes, that is, use metalworking glue to repair.
