What does the term “cutting in” refer to in the context of painting?

The term "cutting in" in the context of painting specifically refers to the technique of painting the edges of a surface before the main areas are rolled or painted. This method is essential for achieving clean, sharp lines and ensuring that the edges are properly painted without getting paint onto adjacent surfaces. Cutting in is often done with a brush, allowing the painter to have more control in tight spaces, such as corners, around trim, and along ceilings, ensuring a uniform finish in the broader sections that follow.

By carefully defining these edges first, the painter can roll or apply paint more efficiently to the larger areas without the worry of overlapping onto surfaces that require a different color or finish. This technique is especially important in ensuring a professional appearance to the completed work, emphasizing precision and attention to detail.
