If a run is noticed in the paint application, what should be done?

When a run is noticed in the paint application, allowing it to dry completely and then sanding down before reapplying paint is the best course of action. This approach ensures that the surface is prepared correctly for a uniform finish. After the paint has dried, sanding helps to smooth out the run and feather the edges, creating a seamless transition between the repaired area and the surrounding paint. It allows for good adhesion of the new paint layer, leading to a more aesthetically pleasing and durable finish.

Immediately scraping off the run could damage the underlying layers or create an uneven surface that may not hold paint well. Using solvents with a brush may lead to further complications, such as discoloration or an uneven finish, and ignoring the issue could result in a poor-quality job that would likely require more extensive corrections in the future. Taking the time to properly address the run by allowing it to dry, sanding, and then reapplying is essential for achieving a professional-quality result.
