Overhead doors, for example, are equipped with a coil coating in 9 out of 10 cases, also known as pre-painted steel or aluminum. For instance, a colorcoat prism, PVDF, silicone polyester, HPS plastisol, etc. Coil coating is a factory-applied process under high temperature, which cannot be used for repairs. Frames and facades, as well as pedestrian doors, are often coated with powder coating, which is an electrostatic process combined with temperature, also factory work under controlled and constant conditions.

In any case, these are excellent substrates for our paint systems. The products we use originate from the automotive industry and are specially developed and applicable for repair work on sandwich panels and profiles. The paints seamlessly match the durability and appearance of the applied coil coat. We are familiar with all types of coating systems and have the most common colors in stock.

No color or building is the same. Every new coil, despite having the same RAL code or name, has a different color or hue. This is often due to the fact that most pigments for paints and coatings are derived from natural sources, which can lead to variations between deliveries. In the case of metallic finishes, there is another dimension referred to in industry jargon as “flop,” which describes how the metallic particles rest on the surface and can create a light/dark effect. It’s similar to a long-haired carpet: the color itself doesn’t change, but if you rub over it, you can create light and dark spots.

Buildings and cladding fade over the years, and one of our areas of expertise is that we “retint” the color on-site with the right pigments to match the existing color.

Van Heemskerk masters the techniques to mix the most suitable color during repairs. We strive to make repairs “invisibly unnoticeable” to the satisfaction of our customers.
