Spray Gun Classification: Matching Tools to Painting Needs

Selecting the right spray gun is critical for any painting project, but with so many models on the market, understanding their classifications can be challenging. Over the years, spray gun technology has diversified, making it possible to find the perfect tool for every task—from fine automotive finishing to heavy industrial coating. This article breaks down the major spray gun categories and their typical uses.

1. Conventional (High Pressure) Spray Guns

This classic spray gun design uses compressed air at high pressure to atomize paint, producing a fine, even mist. It’s a favorite for automotive shops and furniture makers seeking a smooth, glossy finish. However, conventional spray guns generate more overspray and tend to waste more paint compared to modern alternatives.

2. HVLP Spray Guns

HVLP (High Volume, Low Pressure) spray guns have transformed painting by combining efficient paint transfer with a fine finish. Using lower air pressure, these spray guns reduce overspray and environmental impact, making them a top choice for body shops, woodworking, and precision jobs.

3. Airless Spray Guns

When speed and surface coverage are priorities, airless spray guns stand out. They rely on a high-pressure pump to force paint through a small nozzle, creating a consistent spray without air. Airless spray guns are ideal for large-scale projects like exterior walls, decks, and industrial equipment, and they excel with thick or viscous paints.

4. Feed Systems: Gravity, Siphon, and Pressure Feed

Gravity feed spray guns feature a cup above the gun, allowing paint to flow down naturally—great for detailed work and easier cleaning. Siphon feed guns, with a cup below, are good for heavier materials and larger volumes. Pressure feed systems use an external tank and are found in industrial settings, providing uninterrupted spraying for big jobs.

5. Specialty Spray Guns: Detail and Texture Guns

Specialty spray guns are designed for unique applications, such as detail spray guns for small touch-ups or intricate designs, and texture guns for applying plaster or textured finishes. These tools make it possible to tackle very specific painting requirements with professional precision.

Conclusion
Understanding spray gun classifications empowers painters to achieve the best results on any project. By selecting the right type—conventional, HVLP, airless, or specialized—users can balance efficiency, quality, and cost, ensuring consistent and beautiful finishes every time.
