Dust-free sanding in decorating has several benefits. Firstly, it helps to maintain a cleaner and healthier environment by reducing the amount of dust particles in the air. This means less cleanup after the sanding process and less risk of breathing in harmful particles. Additionally, dust-free sanding can also improve the quality of the finished surface by preventing dust from settling on the freshly sanded area. So you get a smoother and more professional-looking result. It's definitely a great choice for your sanding needs
