Paint spraying technique: The most important things to know for optimal coating results
-Keep recommendation on viscosity according to instruction manual.
-The surfaces to be covered need to be clean, dry, free of dust, fat - and in the case of metals rust. The micro-thin atomized paint particles settle on the surface to form a wafer-thin film.
-Practice with sample pieces before working on the actual object. This is how you can learn a lot about optimal output settings and the different spray jet settings.
-When using solvent-based paints make sure that there is a good air circulation. Use respiration protection if necessary. Prior to making your purchase you might also want to think about suitable waste management.
A bit of a cheesy JML video but a good example of the type of spray painting products they produce.
