- The substrate is unclean (dirt, dust, grease).
- Natural resins and waxes in the wood (pine, exotic wood, etc.), melamine film.
- The base lacquer coat is too thick and the base surface is over-sanded (overly fine sanding).
- Insufficient sanding of the base/interlayer sanding.
- Mismatch between the base and the final lacquer.
- Droplets of the lacquer are too dry when they fall on the workpiece.
- Too much time has elapsed between the sanding and the lacquering.
- Clean and degrease the surface.
- Use the recommended insulation, sand the foil before applying the lacquer.
- Smaller application of the lacquer, lower spray pressure.
- Check the sandpaper quality (wear and tear).
- With machine sanding, keep an eye on the pressure and temperature to prevent overheating of the sanded lacquer coat.
- Use compatible materials.
- Use a slow thinner, check the distance between the workpiece and the spray gun, increase the flow of the lacquer.
