Painting & spray booth

Spray painting is the process of applying protective and decorative layers — primers, basecoats, enamels, lacquers, powder coatings — to the surface of a part using an airbrush or electrostatic spray gun. The objective is twofold: corrosion protection and weatherproofing, and aesthetic finishing with controlled colour, gloss and texture. The spray booth creates the controlled environment needed: overspray extraction, adequate lighting, temperature and humidity control to guarantee optimum coating adhesion.

Application technologies range from the HVLP (High Volume Low Pressure) gun — which reduces overspray for quality manual painting — to automated robotic systems, through to electrostatic powder coating baked in an oven, which guarantees uniform thicknesses, excellent chemical and mechanical resistance and zero solvents. Surface preparation (degreasing, phosphating, primer) is as decisive as the paint itself for the durability of the final coating. In the maker context, compact booths and bench-top HVLP systems allow quality painting on a reduced scale.
