This fleece-backed sponge sandpaper is a flexible sanding tool designed for high-precision surface finishing. It uses a high-density, high-quality sponge as the base material, coated with selected abrasives (such as silicon carbide or alumina), and features a premium Velcro (slip-on) backing for easy attachment to various pneumatic or electric rotary sanders and handheld sanding boards.

Its unique multi-color visual differentiation system (red, blue, green, and different shades of gray) is not only aesthetically pleasing but also helps users quickly distinguish different grits, effectively avoiding process confusion. The sponge base material has excellent elasticity and absorbency, supporting both dry and wet sanding, perfectly conforming to the uneven surfaces, curved surfaces, and irregular edges of the workpiece, resulting in a uniform and smooth sanding effect.

Automotive detailing and bodywork painting: Used for repairing surface imperfections in car paint, fine-tuning and sanding before topcoat polishing, and smoothing the primer layer.

3D printing model post-processing: Soft sponges are ideal for sanding the curved surfaces, textures, and hard-to-reach details of 3D printed resin or plastic parts.

High-end digital and electronic products: Trimming and polishing the edges of mobile phone cases, laptop cases, and plastic injection molded parts.

Musical instruments and high-end furniture making: Polishing the lacquer finish of guitars, pianos, and other musical instruments; fine-polishing of high-end wood, jade, and metal products.

Hardware and metal polishing: Removing oxide layers and fine-tuning the brushing of stainless steel, aluminum alloy, and other metal products.

Grinding in sequence: It is recommended to strictly follow the order of changing colors from coarse to fine (lowest to highest grit). Skipping grades of grinding may leave scratches that are difficult to remove.

Post-wet grinding maintenance: After wet grinding, please place it in a ventilated place to air dry naturally. Do not expose it to direct sunlight or bake it at high temperatures to avoid aging of the sponge or delamination of the backing.

Pay attention to speed control: When using with a machine, do not exceed the speed limit. Excessive speed and pressure may damage the workpiece surface or burn the sponge due to frictional heat.

Regularly clean accumulated dust: If there is too much dust on the surface during grinding, you can pat or wash the surface residue with water to restore its original cutting power.

• Hook and Loop Design: The hook and loop connection design of the sanding pads allows them to be easily and firmly attached to most 5-inch random orbital sanders, such as die grinders, air grinders, electric drills, etc. It enables the effortless smoothing, sanding, and polishing of various large-area surfaces.
• Ideal for Curved Surface and Sanding: The combination of sandpaper and sponge makes curved - surface sanding much easier. The sponge is elastic and not prone to tearing during the sanding process. Meanwhile, the sponge provides buffering, reducing the risk of scratching the surface during sanding tasks.
• Reusable and Cut - to - size: This sanding sheet is suitable for both wet and dry applications. After use, simply rinse off the impurities on the abrasive grains with clean water, and the sandpaper can be easily reused. Additionally, it can be freely cut into any size and shape according to your specific requirements.
• Extensive Applications: This abrasive soft sanding block is highly versatile. It can beautify furniture by smoothing wood textures, create ideal painting bases on metal and drywall, thoroughly clean kitchenware like stainless - steel and plastic items, and repair drywall blemishes.
