Which of the following is NOT a benefit of using water in sanding?

Using water in sanding has several benefits, but eliminating the need for a vacuum system is not one of them. Water can help the sanding paper to cut more effectively and last longer by preventing clogging, which is why it aids in the longevity of the paper. It also significantly reduces the amount of sanding dust generated during the process, creating a cleaner work environment. Furthermore, using water can provide lubrication, which can help speed up the actual sanding process by allowing for smoother motion over the surface being sanded.

However, a vacuum system is still important for managing dust in a sanding environment. It helps to collect excess dust particles that may still be present during the process, ensuring better air quality and minimal respiratory risks for workers. Thus, while using water improves many aspects of sanding, it does not negate the necessity for a vacuum system to manage dust effectively.
