Professional removal of PUR residues

Normally, unless their size and position are too extreme, PUR residues can be spotlessly removed. So far, we've always been able to fix everything.

PUR has adhesive properties, forming a rock-solid bond with coatings and all sorts of other substrates. Sometimes, if you're lucky, you can use a sharp knife in an out-of-sight spot to scrape the residue off. However, PUR usually leaves a stain. PUR cleaners are highly aggressive. Most coatings are polyurethane-based, which means the cleaner will also affect the substrate!

We start by sanding down the PUR. Afterwards, we prime the panel and respray it in the appropriate colour. Thus far, this has proved the only effective approach. There are no other tools or methods.

9 out of 10 times, panels and profiles 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.

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”. Flop refers to the way the metallic particles are positioned on the surface. This can result in a darker or lighter effect. It's not unlike a high-pile rug: the colour doesn't change, but you get lighter or darker spots depending on the position of the piles.

Properties and sheeting 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.

Van Heemskerk is an expert in mixing the most suitable colour during repairs. We strive for customer satisfaction by making our repairs “virtually invisible!”

It is hard to estimate the costs in advance. They depend on a variety of factors, such as size, lighting, accessibility, paint type and local circumstances.

The price is also affected by the costs of replacement, dismantling and removal of the surrounding construction, which can cause damage, leaks etc. Sandwich panels are often attached with hidden fasteners and cannot simply be removed. On top of that, new deliveries almost invariably differ in colour, which means that repairs and spraying are often a more affordable option.
