“In many cases, the damage can be invisibly repaired without a trace; much depends on the local conditions and the state of the substrate and maintenance performed. Our professionals successfully work daily on both new constructions and buildings that are 30-40 years old, so there is a lot possible.

Overhead doors, for example, are equipped with a coil coating in 9 out of 10 cases, also known as pre-painted steel or aluminum. This includes colorcoat prisma, PVDF, silicone polyester, HPS plastisol, etc. Coil coating is a factory-applied process at high temperature, which cannot be used for repairs. Frames and façades, as well as swing doors, are often coated with powder coating, which is an electrostatic process combined with temperature, making it also a factory process 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.

However, 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 paint and varnish are derived from nature, which can lead to variations with each delivery. In the case of metallic finishes, there is another dimension referred to in the industry as ‘flop’; this describes how the metallic particles rest on the surface, creating light and dark effects. Compare it to a long-haired carpet: the color doesn’t change, but when you rub over it, you create light and dark spots.

Buildings and cladding fade over the years, and one of our specialties is that we can ‘re-tint’ the color on-site with the right pigments so that it matches the existing color.

Van Heemskerk has mastered the techniques to mix the most suitable color during the repair process. We strive to make the repairs ‘invisibly unnoticeable’ to the satisfaction of our customers.

We work both nationally and internationally. We operate daily throughout the Netherlands, Belgium, and Germany. We are also project-based active far beyond these areas, such as in North and South America and the Middle East.

We work for reputable panel manufacturers, building owners or tenants, property managers, assembly companies, construction companies, and individuals.

Yes, the scope of application is very broad; see other sections on the website for this. This includes the repair of sandwich panels and cladding. We also come into contact with composite and wood constructions; we usually have a solution even if it’s not listed on the site
