Buying Guide: How To Choose The Right Polyurethane Spray Gun
- What coating type and viscosity will you spray? Heavier polyurethane coatings may need larger nozzle sizes (1.7–2.0mm) and a more robust air supply, while thinner finishes benefit from smaller tips to reduce paint buildup.
- Do you prioritize overspray reduction or speed? LVLP guns minimize overspray and are great for indoor use, while HVLP kits offer strong atomization for smooth finishes but may require more ventilation.
- Is ease of setup important? All-in-one kits with regulators, separators, and guides help beginners start quickly, whereas pro-grade systems offer more granular control for precise results.
- What surface are you coating? Car finishes demand fine control and consistent atomization; furniture and cabinets benefit from adjustable fan patterns and material flow for even coverage.
- Maintenance and cleaning: Will you work with solvent-based polyurethane? Choose a system with easy cleaning paths and corrosion-resistant components to extend life.
- Budget and ongoing costs: LVLP guns tend to be affordable upfront, but consider nozzle availability and cup sizes for long-term use.
