Matte Effect Painting Paint Structure
Technology
On vehicles with matte effect only the regulations for painting with a matted clear coat apply. The application can take place directly on the base paint or on an existing clear coat.
There is a risk or cloudiness from too dry of application due to uneven drying or due to unabsorbed spray mist. For this reason large surfaces should be painted early in the morning. It could be the case that the work order must be moved a few days.
Base Paint Color Structure
Due to the matte structure of the clear coat the color and the pigmentation effect of the base paint can not be clearly allocated. For this reason it is recommended, to prepare two to three versions of the base paint in the foreground of the sheet metal.
Matte Clear Coat Color Structure
It is recommended to use a gloss level measuring device.
Despite the gloss level measurement three different matte levels should be applied.
Application
To obtain a homogeneous material effect, the following is recommended:
To reach the determined matte level, the clear coat must be mixed using a scale.
The spraying distance to the object is larger than the standard application, to use the full the atomization of the spray mist.
It is advisable to apply both spray applications in cross coats on horizontal replacement parts, (To prevent streaking).
Pay attention that there is even overlap of the spray passes and that enough wet spray film is applied.
When applying to large objects, the overlap area of the second spray application must not lay in the overlap zone of the first spray application and should instead be moved.
If possible, an entire painting process should be divided up in sections, meaning the vehicle body is separated into attachments, and painted in order to prevent overlapping zones and spray mist.
Make sure that the matting can change over time.
Applies in principle:
- Spot repair is not required.
- Air drying is not recommended.
- In the regulation a base painting is required.
- Glossy spots can only be eliminated by new paining in the regulation
Because the matte clear coat cannot be reworked, pay attention to the following notes, to prevent dust inclusions:
- The vehicle must be kept in a completely clean condition from the outside. An underbody wash or the use of a steam cleaner in the foreground is recommended.
- The paint booth should also be completely clean. A filter change shortly beforehand may be preferred. But then only as the second or third work order, because a lot of dust is stirred up right after a filter replacement.
- Scrub the components thoroughly after sanding and clean with Silicone Remover.
- Sufficiently tape off the vehicle. Cover the painting stand.
- Clean all components to be painted again using Duster :VAS 6177 before painting.
