Painting/Repairing Low Gloss Finishes

Painting and Repairing Low Gloss FinishesIn the hands of a custom painter, a smooth matte finish can turn your ride into a work of art. But, it's not just for the custom jobs any longer. Over the past few years, matte finishes have grown in popularity among refinishers and OEM designers. A matte or low-gloss finish is a unique exterior finish that gives your vehicle a distinctively different appearance.

The application process for achieving a matte finish is really no different than a normal high-gloss clearcoat. The car would be sprayed with sealer, with your basecoat color, and when you would normally spray a high-gloss clearcoat, you'll replace that with one of PPG's premium matte clears.

Watch the video below for some tips and tricks on how to achieve a great matte finish.

Tips for achieving a Low Gloss Finish

Applying a Matte ClearAfter color has been sprayed, the first coat of clearcoat should be sprayed as a medium wet coat. That coat should be allowed to dry down to a uniform dull appearance before the second coat is applied. Any not completely dull areas could result in a blotchy, inconsistent gloss in your final appearance.

The second coat should be applied as a full wet coat, and allowed to dry for a full 5-10 minutes, and then a drop coat will get applied. A drop coat helps to achieve that final, uniform appearance. That final coat should be allowed to dry to a completely dull appearance before baking it to cure.

The most important tip is proper preparation and cleanliness. The paint booth, the painter, the car, and the equipment all need to be as clean as possible. Any dirt or dust that comes into the paint job while the painter is spraying the clear can't be polished out because that would raise the gloss of the clearcoat.

Matte Band Guides

Matte Banding Guides
1 Flat Aligns with very low gloss clearcoats (Lamborghini and Lexus)
2 Matte Little or no OEM activity in this range at the current time
3 Eggshell Aligns with the reduced-gloss clearcoats seen on Mercedes-Benz and other OEMs
4 Satin This range most commonly seen on bumbers and lower body cladding parts
5 Semi-Gloss

The width of the bands reflects the natural variation seen in OEM colors which feature a matte or reduced gloss clearcoat. The bands also accommodate the variation in gloss levels achieved by refinish products as a result of changes in application process, equipment choice, product selection, etc.

NOTE: The actual gloss achieved by a painter can vary significantly as a result of variables in application, temperature, hardener/thinner choice, etc. The recommended band and the matting agent addition will at best only ever be a guide. It is strongly encouraged that a test panel be sprayed before painting the car.

Matte banding guides are available for both PPG and Nexa Autocolor® brands. Distributors can order them through PPG Online Ordering.
