Your doors and frames will be like new again

In many cases, the damage can simply be fixed virtually invisibly. However, this does depend on local circumstances, the condition of the substrate and prior maintenance. Every day, our experts successfully perform work on both new buildings and buildings that are 30-40 years old, so there is plenty we can do.

For example, 9 out of 10 times, overhead doors feature a coil coating, which is also known as pre-painted steel or aluminium. This could be a colorcoat prisma, PVDF, silicon polyester, or an HPS Plastisol coating, among others. Coil coating is a factory process involving extreme heat. As such, it cannot be applied for repairs. Frames, façades and wicket doors often feature a powder coating. This is an electrostatic process combined with temperature, i.e. a factory process taking place under constant and controlled conditions.

Whatever the method, these are all excellent substrates for our paint systems. The products we use are derived from the automotive sector and were specifically designed for repairs to sandwich panels and profiles. The paints seamlessly fit the applied coil coat when it comes to durability and appearance. We are familiar with all types of coating systems and always have the most common colours in stock.

No two colours or buildings are the same. Even if they have the same RAL code or name, every new coil will have a different colour or appearance. This is because most pigments for paints and lacquers are derived from nature, so their properties may differ from shipment to shipment. This phenomenon has an extra dimension in case of metallics, which professionals call “flop”. This refers to the way metallic particles are positioned on the surface, which can result in a darker/lighter effect. You can compare this to a high-pile carpet. The colour doesn't change, but if you run your hand over it, you will get lighter and darker areas.

Buildings and panels suffer from discolouration over the years. One of our specialisations is “retinting”. This means we use the right pigments to touch up the damage so it matches the existing colour.
