Analysis by road paint manufacturers on whether to remove non durable coatings after repainting?

Non durable coatings usually refer to those coatings that do not have long-term protection or durability. This type of coating may have a very beautiful appearance, rich colors, and be suitable for short-term use. However, non durable coatings are often prone to fading, peeling, or mold growth when exposed to sunlight, moisture, and corrosive environments. Therefore, as a manufacturer of marking coatings, it is important to remind everyone that such coatings usually need to be reapplied regularly to maintain good visual effects and protective performance.
In the process of coating construction, especially for the recoating of non durable coatings, besides selecting suitable products, the process of coating is often overlooked. So how did the two-component marking paint play its role in the re coating of old lines? Here, the TOP ROAD marking paint manufacturer’s editor will explain the issue of recoating durable and non durable markings.

For non durable markings, the recoating of non durable markings generally does not require the removal of the old markings. In fact, many successful foreign experiences have shown that for the recoating construction of non durable markings, not only should the original old markings not be removed, but when the old markings are not completely worn out or even used ideally, recoating a layer of non durable markings of the same nature is already very effective, and even better than directly constructing road markings of the same type and thickness on exposed road surfaces. There is also data indicating that the application effect of directly applying thicker coating durability markings on thinner coating non durability markings is poor. For example, the effect of directly applying hot-melt road markings on cold paint is very poor, while the application of thinner two-component spray painted markings on thicker hot-melt markings has gained a lot of successful experience abroad.
The manufacturer of marking paint introduced that for durability markings, as mentioned above, re coating thinner two-component spray type markings on durability markings such as hot melt scraping, oscillating markings, and formed marking strips can achieve good results. However, the prerequisite is that the old hot melt markings cannot have been applied three or four layers already, which everyone still needs to pay attention to.

In summary, manufacturers of marking coatings remind everyone that removing lines is a very important and cannot be ignored step in the recoating of non durable coatings. By proper wire removal work, not only can the adhesion of the new coating be improved, but it can also effectively avoid color difference, improve weather resistance, and ensure the beauty and quality after long-term use. Every detail is crucial for the quality of the coating, so when carrying out recoating work, please take it seriously, choose the right materials, and apply them reasonably to achieve the desired effect.
