Loss of gloss
Definition
Mat or matted paint surface.
Causes
- Paint sinkage
- Excessive film thicknesses
- Weathering (results of the action of sulfur dioxide or nitrogen oxide combined with moisture and/or severe UV radiation)
- Wrong amount of hardener
- Poor or incorrect paintwork care
- Incorrect polishing (polish too aggressive or polished in direct sunlight)
- Weathered surfaces due to poor paintwork aftercare
- Car wash brushes too coarse
- Car cleaning agent too aggressive or concentrated
- Newly repaired paintwork weathered too early. Thick coats or newly repaired paintwork are sensitive to condensation (below dew point)
- Insufficient air circulation during drying
HOW TO AVOID
- See entry on “Sinkage”.
- Keep to recommended film thicknesses. Use the Glasurit grey shade concept for poor covering colors (yellow/red). The Glasurit grey shade concept comprises the Glasurit HS primer fillers 285-505 gray, 285-555 black and 285-655 white.
- Ensure regular paintwork after-care.
- Keep to recommended mixing ratios.
- See entry on “Aftercare of vehicle paintwork”.
- Keep to recommended film thicknesses and drying times.
- Check air circulation, replace floor and ceiling filters if necessary. If in doubt, consult your spraybooth manufacturer.
- See entry on “Sinkage”.
REPAIR
First polish with Glasurit 562-1602 Fine Polishing Compound and finish with any standard high-gloss polish. If the gloss cannot be restored, you need to repaint.
