Drying
Haze / blush
Misty, milky paint surface - moisture from the air penetrates the fresh layer before it dries.

Cause
- The thinner is too fast in relation to the temperature and conditions - the varnish dries too quickly, the surface cools down and attracts moisture from the air
- Too high air pressure in the gun - accelerates evaporation and intensifies the cooling effect of the surface
- Low ambient temperature combined with high humidity - classic conditions for condensation on fresh paint
- A cold painted element in a warm cabin - the temperature difference causes moisture to condense on the surface
- 2K varnish exposed to humid air too early - cross-linking not yet complete
- Failure to respect the dew point - surface temperature too close to the dew point of the air in the cabin
- Incorrect spray pressure on metallic and pearl basecoats - too high a pressure confuses the metal flakes and causes uneven light reflection resulting in a cloudy effect
- Wrong base coat thinner - too fast and the metal flakes won't have time to become parallel to the surface before the layer dries
- The distance between the gun and the painted surface is too large for metallic bases - the paint reaches the surface partially dry, the metal flakes are positioned incorrectly
- Too thin layer of metallic base - insufficient amount of metal flakes causes uneven coverage and a hazy effect, especially visible in silver and champagne
Prevention
- Select a diluent appropriate to the current temperature and humidity - in difficult conditions, use a slower-evaporating one
- Reduce the air pressure during painting to that recommended in the technical data sheet
- Painted elements must be at ambient temperature - acclimatization is mandatory before painting
- Avoid painting when the relative humidity exceeds 80%
- Check the dew point before starting work
- Follow the recommended temperatures and drying times before leaving the item outdoors
- Do not paint in a cold or humid environment without properly preparing the booth
Repair
Superficial opacity - clear varnish
- Bake the element at 60°C for 20-30 minutes - the heat drives moisture out of the layer
- After cooling, polish the surface with a fine paste
- If the shine hasn't returned, sand the clear coat off and reapply
Turbidity in the base layer
- Heat the element for 5-10 minutes at 60°C
- Cool to ambient temperature
- Apply one or two layers of base with a slowly evaporating thinner
- Coat with clear according to the technical data sheet
Widespread or deep clouding
- Heat the element for 20-30 minutes at 60°C
- Sand off the entire top layer
- Before reapplication, check the cabin conditions and select the appropriate thinner for the current temperature and humidity
- Reapply the system observing the evaporation times
