Overview of the basic techniques used in spray painting, including distance control, angle of spray, and overlapping strokes.
Introduction to Spray Painting Techniques
Designed as a quick‑reference guide for beginners and intermediate users.
| Component | Function | Typical Options |
|---|---|---|
| Paint Supply | Holds the coating (can, bucket, or cartridge). | Aerosol cans, HVLP/air‑less tanks, gravity‑feed cups. |
| Pressure Source | Generates the airflow that atomizes the paint. | Compressor, turbine, built‑in pump (spray guns). |
| Gun/Nozzle | Shapes the spray pattern and controls droplet size. | Flat fan, round, adjustable fan, air‑cap size (e.g., 1.0‑1.8 mm). |
| Trigger/Control Valve | Regulates flow of paint and air. | Single‑action (on/off) or dual‑action (air & paint independently). |
| Filters & Strainers | Remove debris that could clog the nozzle. | Inline mesh filters, cup filters. |
| Safety Gear | Protects the user and environment. | Respirator, goggles, gloves, coveralls, proper ventilation. |
| Adjustment | How to Set | Effect |
|---|---|---|
| Air Pressure | Start at 20–30 psi for HVLP; 40–70 psi for conventional guns. | Controls atomization; too high → overspray, too low → orange peel. |
| Fluid Flow | Adjust the paint‑control knob (or cup) until a steady stream appears without dripping. | Determines coverage rate. |
| Fan Width | Rotate the air‑cap or use a different nozzle. | Wider fan = faster coverage; narrower fan = detail work. |
| Spray Distance | Hold gun 6–12 in (15–30 cm) from the surface. | Consistent distance yields even thickness. |
