Definitive Guide: Choosing the Perfect Spray Gun for Your Needs

Proper application of coatings and finishes is an important part of many different industries. Spray guns are commonly used for projects that require an even, smooth, and consistent application. Knowing how to choose a spray gun is vital to achieving the best results and maximizing efficiency.

Spray guns come in a variety of types, sizes, and price ranges. The type of spray gun you need will depend on the project you are working on and the material you are using. The most common types of spray guns include:

• HVLP (High Volume, Low Pressure) – HVLP spray guns use a high volume of air at a low pressure to atomize the paint. This results in less overspray and a smoother finish.
• LVLP (Low Volume, Low Pressure) – LVLP spray guns use a lower volume of air at a lower pressure than HVLP guns. This results in even less overspray and an even smoother finish.
• Airless – Airless spray guns use a high pressure pump to force the paint through a small nozzle. This results in a high-pressure stream of paint that can be difficult to control, but it can also produce a very smooth finish.

Once you have chosen the type of spray gun you need, you will need to consider the size and price range. Spray guns come in a variety of sizes, from small handheld guns to large industrial models. The size of the gun you need will depend on the size of the project you are working on. The price of a spray gun will vary depending on the type, size, and features of the gun.
