Advice on paint defects
Loss of Gloss
Matt or matted paint surface.
- Paint swelling.
- Excessive film thicknesses.
- Weathering (results of the action of sulphur dioxide or nitrous 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 aftercare maintenance.
- 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 chapter on “Swelling”.
- Keep to recommended film thicknesses. Use the Glasurit grey shade concept for poor covering colours (yellow/red). The Glasurit grey shade concept comprises the Glasurit HS primer fillers 285-505 grey, 285-555 black and 285-655 white.
- Ensure regular paintwork aftercare.
- Keep to recommended mixing ratios.
- See chapter 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.
First polish with Glasurit 562-1602 Fine Polishing Paste and finish with a commercially available high gloss polish. If the gloss cannot be restored, you need to repaint.
