Sponge Sander Backing Pad | For Contour Sanding | 6-Inch 150mm 15-Hole

This soft sponge pad goes between your sander's backing pad and the sanding disc. It adds a layer of cushioning, which helps when sanding curved or uneven surfaces. This 6-inch (150mm) pad helps prevent marks and gives a more even finish on objects that aren't flat. Features and Benefits - Soft foam construction - Bends to fit curves and shapes, giving you an even sanding result without flat spots. - Hook-and-loop design - Attaches securely between your sander's pad and your hook-and-loop sandpaper. - 15-hole configuration - Matches common dust extraction patterns to help keep your work area clean. - Reduces vibration - The foam absorbs some of the tool's shaking, making it more comfortable to use for longer jobs. Applications - Car bodywork - Helps sand curved fenders and panels smoothly before painting or polishing. - Furniture finishing - Works well for sanding rounded table edges, chair legs, and other non-flat shapes. - Woodworking projects - Use on bowls, spindles, or any turned item to get a consistent surface. What It Is This is a 6-inch 150mm soft sponge backing pad designed for contour sanding. It features a hook and loop attachment system, making it compatible with various random orbital sanders that accept 150mm hook and loop discs. The soft sponge material allows for feathering and conforms to curved surfaces, preventing swirl marks often associated with rigid pads. It has 15 holes for efficient dust extraction during use. Key Uses & Applications This sponge sander backing pad is ideal for contour sanding and preparing irregular surfaces. It is used with a random orbital sander, which provides a dual-action sanding motion (spinning and oscillating) to reduce swirl marks. Tradespeople use random orbital sanders for tasks like automotive bodywork, woodworking, and furniture finishing. The soft sponge allows for even pressure distribution across uneven profiles, making it suitable for fine finishing and intermediate sanding stages before painting or varnishing. How to Choose When selecting a backing pad, ensure the diameter matches your sander; this pad is 150mm. Verify the hole quantity (this one has 15 holes) for proper dust extraction with your tool. For contour sanding, a soft sponge material is crucial. Consider your sander's attachment type; this pad uses hook and loop. For general-purpose sanding, a firmer pad might be more suitable, but for delicate or curved work, the soft sponge is preferred to prevent gouging. Grit / Spec Guide This backing pad is 150mm in diameter with 15 holes and a soft sponge material. For contour sanding, pair it with appropriate grit sanding discs. For initial material removal on contoured surfaces, start with coarser grits like 80 grit. For refining the surface and preparing for finishing, move to finer grits such as 150 grit. The soft sponge helps prevent swirl marks when using a random orbital sander, especially with variable speed settings, by allowing the abrasive to follow the contours gently. Care & Safety Always ensure the backing pad is securely attached to your random orbital sander before use. Regularly inspect the pad for wear or damage, especially the hook and loop surface, as a worn pad can lead to poor sanding results or discs detaching. For safety, always wear appropriate eye protection and a dust mask when operating a random orbital sander, as the 15-hole dust extraction system may not capture all particles. Store the pad in a clean, dry place away from direct sunlight.
