Finish and Repair

3M™ Wetordry™ Cloth Disc 481W features silicon carbide – a mineral that is very sharp and commonly used for low-pressure applications such as paint prep. Although it breaks down faster than aluminum oxide, silicon carbide produces a superior finish. To achieve a consistent scratch pattern that is often desirable for final finishing, users apply light pressure. One of its greatest features is its versatility – it may be used on a variety of substrates, including metals, whitewood, softwood, and hardwoods. 3M™ Wetordry™ Cloth Disc 481W is used with a disc pad holder, so operators can abrade the workpiece by hand.

The Benefits of Cloth-Backed Discs

The cloth backing on this disc is a durable, water-resistant polyester screen. Our 3M™ Wetordry™ products are engineered to include our proprietary waterproof cloth backing, which supports both wet and dry applications. Cloth-backed discs are known for their durability and flexibility, making them a good first choice when working with metal or for heavy wood stock removal. However, these applications tend to produce a significant amount of dust, which can clog the abrasive points and create an inferior work environment. Sanding with water can minimize these effects by rinsing dust away from the workpiece and the abrasive surface.

Some technicians prefer to use the abrasive dry because they can quickly inspect the work. Wet sanding, on the other hand, uses water as a lubricant. This keeps the abrasive clear of loading and can prolong the life of the abrasive.
