Treatment of wear and chalking

Coatings sometimes show white or greyish discolouration. This is called ‘chalking’. It makes it seem as if the intensity of the original colour has diminished. You'll start seeing stains and lines. This is a sign that the coating was severely affected by UV radiation.

It is a common problem on façades and roofs with high-pigment colours, such as white, blue, red, yellow and anthracite, and is caused by ambient factors, such as UV radiation, excess pollution and improper maintenance. Sometimes, inappropriate detergents may be the cause of this issue. Chalking means that the paint is being ‘pulverised’. The top layer of the coating has been damaged, and now has an open structure. As such, dirt adheres to the surface more easily, thus accelerating the chalking process. This process cannot be halted without proper treatment.

Maintenance has to be performed soon, as the existing coating has passed its expiry date. In this case, the maintenance process entails recoating (respraying) the surfaces. Van Heemskerk can professionally respray your existing steel roof or façade sheeting. Recoating the roof or façade will restore its protective properties. The chalking will disappear and the lifespan of the façade and roofs will be extended significantly.

FAQ
How do I know my façade is suffering from wear or chalking?

If your roof or façade is suffering from chalking, the surface will look dull and dirty. On top of that, the coating will stain severely and is extremely susceptible to dirt. Signs of this include greasy fingers, leakage marks etc. The coating behind downspouts or in the shade is often in a better condition, as these spots are less exposed to UV radiation.
