The cause of paint peeling lies in the substrate! By properly performing substrate treatment (surface preparation), it is possible to prevent paint peeling.
"Ultimate Paint Stripping Prevention Measures" The measures against paint stripping are very simple. - Surface preparation is done through blasting, removing all foreign substances attached to the surface. - Use paint with excellent adhesion to the material appropriately. - Select a coating specification with high corrosion resistance and weather resistance to prevent stripping for a long time. - Manage the application to maintain an appropriate film thickness of the coating. By adhering to the above four points, a paint that will not peel for over 30 years can be completed! 【Improving the Service Life of Heavy Anti-Corrosion Coatings】 https://www.nc-net.or.jp/company/98405/product/detail/186702/ Harada Iron Works is equipped with large air-operated blasting equipment. We commonly use "grit blast" and "sand blast" abrasives, but we can also accommodate other abrasives, so please feel free to inquire. After blasting, prompt rust prevention treatment is necessary, but since Harada Iron Works also has a painting factory, we can provide a consistent response from blasting to topcoat application in-house.

basic information
"Causes of Paint Peeling" 1. Inadequate Surface Preparation (Substrate Adjustment) If the surface preparation is insufficient, residues such as oil, oxidation films, rust, and paint may remain on the surface, leading to poor adhesion and peeling. 2. Compatibility Between the Object and the Paint If the paint used does not match the material of the object being painted, it will not adhere properly and will peel. 3. Mixing of Paint and Painting Intervals Paint should be used with the appropriate mixing ratio and in the correct painting environment, and the painting intervals must be adhered to; otherwise, insufficient adhesion will result in peeling. 4. Aging Deterioration Paint deteriorates over the years due to exposure to UV rays, rain, and wind. Initially, the gloss diminishes, cracks occur, adhesion strength is lost, and ultimately, peeling occurs. Regarding points 2 and 3, these are basic aspects of painting, so instances where they are the cause are likely to be rare. The most common cause is 1, "Inadequate Surface Preparation (Substrate Adjustment)." Electric and manual tools cannot remove all foreign substances adhered to the surface. It is necessary to determine how much needs to be removed, considering the current condition of the product and its durability. This judgment is not easy, and the process itself is difficult, so paint peeling is often caused by inadequate surface preparation.
