Use and application of the wrinkle paint
Before the application, it is necessary to make sure that the surface is free of any residue of previous paintings. For the painting of a metallic material, it could be necessary to sand it before. Some surfaces, on the other hand, may require the application of a primer.
It is recommended to apply the wrinkle paint by spraygun. Thanks to this tool, you can adjust the size of the wrinkles to suit your taste. For an effective application, the nozzle of the spraygun must have a diameter between 1.8 and 2.5 mm and must exert a pressure of 3-4 atmospheres. It is recommended to apply a layer of paint of 300 microns thick.
In order to make this solvent-based paint get the typical wrinkled effect, is necessary to dry the object painted at a temperature of 80 °C for 20 minutes. You can use either an oven or infrared lamps. In order to get the desired result, it cannot be underestimated the importance of a correct temperature. If the paint dries at room temperature, in fact, the surface would be smooth; at a high temperature, but less than 80 °C, you would get an intermediate result, and therefore not entirely satisfactory.
