The front of this sanding disc features a yellow abrasive surface with a dense, fine-grained texture and high surface flatness. P800 is a fine grit size; the grain is barely visible to the naked eye. It is primarily used for refining sanding marks from previous steps rather than for heavy-duty removal on large areas.
The back features a light beige fleece layer printed with the P800 grit designation and Aozhong branding. The fleece backing is designed to attach to hook-and-loop backing pads, allowing for quick installation and replacement.
The disc features a multi-hole dust-extraction design with a central alignment hole. Small holes are distributed across multiple areas of the disc, enabling the removal of sanding dust when used with a dust collection tray. The 4-inch size is suitable for small areas, localized work, edges and corners, curved surfaces, and finishing tasks.
This product is composed of P800 fine-grit abrasive, resin bonding, polyester film base, flannel backing, and a porous dust-extraction structure for fine sanding applications.
The polyester film backing is a key feature of this product. Compared with standard paper backing, film backing helps improve sanding mark consistency during fine-grit operations.
Compared to standard paper backing, polyester film backing helps provide better control over sanding mark consistency during fine-grit operations, making it suitable for P600, P800, P1000, and P1200 sanding processes.
This P800 yellow polyester film sanding disc is primarily used for fine sanding, surface finishing, paint defect correction, coating refinement, and preparation before finer sanding steps.
P800 is typically used as a transition grit following P400 or P600, and can also serve as a preliminary fine-grinding step prior to P1000, P1200, or P1500.
P800 is positioned between medium-fine sanding and fine finishing. It can be used after P400 or P600 to refine previous sanding marks, and before P1000, P1200, or P1500 for further surface finishing.
