Chalking and fading of color tones
The color tone becomes mottled, gray-milky. Destroyed pigments or overaged paint burdened by environmental influences.

- Sources of defects:
- Weather influences such as intense UV radiation, rain, temperature fluctuations.
- Poor surface care. Surfaces that are well maintained withstand environmental influences longer
- Dissolution of the binder in the paint application.
- Destroyed paint particles by UV light „crumble“ from the surrounding binder.
- Fault prevention:
- Apply materials for outdoor use with integrated UV protection.
- Cheaper materials could be painted over with a UV stable clear coat (observe manufacturer’s specification and its possibilities).
- Reparaturweg
- Start with basic paint preparation. If polishing and waxing do not produce an adequate result here, the only option is a renewed paint buildup
- What happens in this process?
- In 2-K 1-coat paints, pigments are embedded in binders. Thus, they are completely exposed to UV radiation. Due to incorrect/bad care and the aging process, pigments and binders are attacked and destroyed. The „bleeding“ of the components is perceived as chalking with the familiar „gray haze“. A striking feature of this type of damage is that it is predominantly older vehicles with red surfaces that are affected.
