Which of the following actions is necessary for maintaining paint quality during refinishing?

Carefully removing all trim and moldings is essential for maintaining paint quality during refinishing. When trim and moldings are left in place, they can obstruct the painting process, leading to uneven layers of paint or the inability to fully cover surfaces. This can create areas where the original finish may show through or cause issues with paint adherence due to contaminants that may remain beneath the trim.

In contrast, properly removing these elements allows for a more thorough and careful application of paint, resulting in a more professional and aesthetically pleasing finish. It also reduces the risk of overspray, which can complicate the refinishing process and result in additional work.

Maintaining a clean and properly prepped surface is critical to achieving high-quality paint results, and this often involves removing any components that might interfere with that process.
