• 2.0mm nozzle: Recommended for heavy-bodied paints; it can handle substantial materials but may require more passes for even coverage.

Adjusting the nozzle size according to the paint’s viscosity and the surface’s texture is essential for a smooth finish.

Remember, the larger the nozzle, the more material it will dispense, which can be both a benefit and a drawback. Larger nozzles can cover more area quickly but may also result in excessive paint build-up if not handled correctly. Conversely, smaller nozzles provide more control and finer atomization, which is beneficial for detailed work but can be time-consuming on larger surfaces.

Assessing the Capacity and Material of Paint Cups

When selecting a spray paint gun, the capacity and material of the paint cup are crucial factors to consider. Capacity determines how much paint you can hold at a time, affecting the frequency of refills during a project. For larger projects, a higher capacity cup minimizes interruptions. Conversely, a smaller cup is lighter and may be more suitable for quick or detailed work.

The material of the paint cup also impacts performance and maintenance. Stainless steel cups are durable and easy to clean, but may be heavier. Plastic cups are lighter and may not stick to certain types of paint, making cleanup easier. However, they can be less durable and prone to issues if not handled properly. For instance, a tight plastic lid might cause the cup to deform when forced closed, especially if the cup material is thin aluminum.

• Stainless Steel: Durable, easy to clean, heavier
• Plastic: Lighter, easy cleanup, less durable

It’s important to choose a material that will not react negatively with the type of paint you’re using. For waterborne paints, avoid materials that rust easily after exposure to water.
