• Move the gun in a steady motion: Move the gun in a steady, back-and-forth motion, following the shape of the surface.
• Maintain a consistent speed: Maintain a consistent speed and movement to ensure even coverage.
• Overlap your strokes: Overlap your strokes by about 50% to ensure complete coverage.

Step 3: Monitor and Adjust

While spraying, monitor the process and make adjustments as needed:

• Check for overspray: Check for overspray and adjust the gun accordingly.
• Monitor the material flow: Monitor the material flow and adjust the gun to ensure the correct amount is being applied.
• Check the surface: Check the surface regularly to ensure the material is being applied evenly and correctly.

Common Mistakes to Avoid

Here are some common mistakes to avoid when using an air spray gun:

• Not preparing the surface correctly: Failing to prepare the surface properly can lead to poor adhesion and reduced durability.
• Using the wrong material: Using the wrong material can result in poor performance and reduced durability.
• Not adjusting the gun correctly: Failing to adjust the gun correctly can result in poor coverage and reduced effectiveness.
• Not following safety guidelines: Failing to follow safety guidelines can result in injury and damage.

Tips and Tricks

Here are some tips and tricks to help you use an air spray gun more effectively:

• Use the correct air pressure: Using the correct air pressure can improve the quality and durability of the finish.
