What happens when the spray gun is angled towards the surface?

When a spray gun is angled towards the surface, the interaction between the spray pattern and the substrate can indeed lead to an uneven finish. This is primarily because angling the spray gun can cause the paint to come out in a more concentrated manner on one side, leading to overspray or an inconsistent application.

An optimal distance and angle help ensure that the paint atomizes properly and distributes evenly across the surface. If the gun is tilted or angled incorrectly, areas may receive too much paint while others receive too little, causing inconsistencies in coverage and finish quality. Ensuring the spray gun is held perpendicular to the surface will typically yield a much more uniform application, helping avoid issues such as runs, sags, or dry spots.
