What does "roll coat" refer to in finishing techniques?

• A. Applying a coating by spraying it
• B. Applying a coating evenly over a surface using a roller
• C. Applying multiple layers of coating with a brush
• D. Applying a coating selectively on certain areas

Answer: (B)

The term "roll coat" specifically refers to the process of applying a coating evenly over a surface using a roller. This technique is favored for its efficiency and ability to achieve a uniform layer of finish. Rollers can cover large areas quickly, making them suitable for large surfaces where an even application is important to avoid inconsistencies in the finish. This method is frequently used in various painting and finishing tasks to ensure that the coating is applied consistently and without drips or runs, which can sometimes occur with other application methods like spraying or brushing. Using a roller allows for a streamlined process, particularly in commercial or production environments, where speed and quality are essential. It can also help in achieving a desired texture, depending on the type of roller used. In contrast, the other options describe different applications of coatings that do not align with the characteristics of "roll coat."
