Mottling - no thanks! Spies Hecker Tips

The basecoat is applied and as it starts to dry, irregularities slowly become visible. But this problem can be avoided. Evgeny Khmelev, Head of Training for Spies Hecker Europe, Middle East and Africa, uses Permahyd® Hi-TEC 480 Basecoat to illustrate practical tips to avoid these unwanted effects when repairing metallic colours.

Top results through good preparation

Before starting the painting process, check the humidity and temperature in the spray booth so that the paint mix can be adjusted to the climate. Detailed information can be found in the Climate Guide of the Technical Data Sheet (TDS). When repairing metallic colours, it is even more important to follow the recommendations for nozzle size and spray pressure, and to apply the paint with a fully depressed trigger so that the pigments can be distributed evenly to form an homogeneous film.

One operation with 1.5 sprays

The Permahyd Hi-TEC 480 Basecoat is first applied in a closed spray booth at a normal distance. Then, the effect pass is applied over the wet paint at a slightly larger distance from the substrate in order to achieve a uniform effect and complete hiding.

Fix irregularities straight away

Immediately after application of the basecoat, the paint film should appear uniform. This shows that the basecoat was not applied too wet. Should any irregularities in the finish become visible, they can be fixed with another effect coat. Khmelev says, "Make sure you apply this additional effect coat with even more distance, and only if the basecoat is still wet."
