Decomposition of the binding agents at the paint surface, resulting in the release of colour pigments.
- Wrong amount of hardener
- Topcoat film builds too high
- Weathering (aggressive environmental influences such as sulfur dioxide or nitrogen oxide combined with moisture and/or severe UV radiation)
- Poor paintwork aftercare
HOW TO AVOID
- Keep to recommended amount of hardener
- Keep to recommended film builds. For colours with poor hiding power (yellow/red), use Glasurit 285-95 HS Tintable Filler as an undercoat to provide the colour (in keeping with best practice in the automotive industry).
- Regular paintwork aftercare (see ‘Aftercare of vehicle paintwork’)
First polish with Glasurit 562-1602 Fine Polishing Compound and finish with any standard high-gloss polish. If you are unable to repair the chalked surfaces in this way, you will need to sand the defective layer and repaint it.
