What can help minimize runs in paint application?

Using a low-pressure spray gun setting is effective in minimizing runs in paint application because it allows for better control and atomization of the paint. A lower pressure results in a finer mist being sprayed, which helps to evenly distribute the paint on the surface. This can prevent the paint from applying too heavily in one area, which is a common cause of runs. With reduced paint volume being projected, it also allows for more precise application, reducing the likelihood of drips and sagging.

In contrast, applying thick coats typically increases the likelihood of runs, as heavier layers of paint are more prone to sagging under their own weight. Mixing paint too quickly can introduce air bubbles, resulting in an uneven application that may lead to runs. Painting under high humidity conditions can affect the drying time, causing the paint to remain wet longer, increasing the chance of runs as well. Therefore, the low-pressure setting emerges as the best practice for achieving a smooth, run-free finish.
