TECH TIP - Repairing a Matte Finish

A dull matt or shimmering satin surface gives a vehicle a special style and makes it stand out from the cars with gloss finishes. However, repairing matt finishes poses particular challenges for bodyshops.

Repairs require precise preparation and considerable professional skill. What is common practice for high gloss clear coats is out of the question for matt paint finishes. The more matt a matt clear coat is, the more accurate the preparation, basecoat application and clear coat use has to be. 

1. PREPARE AND CLEAN AS USUAL

Prepare for the entire matt clear coat application, as blending of the matt clear coat is not possible.

2. BASECOAT APPLICATION AND FLASH OFF

Apply the basecoat as per normal Standoblue process. Allow for sufficient flash-off time afterwards.

3. APPLY MATT CLEAR COAT

Apply the first spray pass and let it flash off for 15 minutes at 20°C. Then apply a second spray pass. Let the vehicle part flashoff a final time before force drying it for 10 to 15 minutes.

The clear coat/Special Matt mixture must also be stirred carefully before adding the hardener.

4. DRYING IN THE SPRAY BOOTH

Allow the painted vehicle part to dry for 45 to 50 minutes at 60°C to 65°C panel temperature. 

Treat all fresh matt paints with the greatest are. Currently, damage to surfaces can only be repaired by refinishing complete panels. Contamination, for example with grease, adhesives or sealants, must be removed immediately with solvent-free cleaner. Do not use any solvents!
