white sandpaper

It is mainly used for grinding and polishing of machine tool, car, ships, instrument, furniture and wood, plastic handicrafts, mechanical components, etc.

1. Woodworking and Furniture Making

• Coarse Sanding (P40-P80): Used for sanding raw wood, removing old paint, and smoothing rough wood surfaces.

• Medium Sanding (P100-P180): This is the most commonly used grit range in woodworking. It is used to remove coarse sanding marks and prepare the wood for painting or oiling. It is also used for sanding putty, fillers, etc.

• Fine Sanding (P220-P400): Used for sanding the primer layer to obtain a very smooth surface, preparing it for the topcoat. For open-pore finishes, this grit range is also often used for final sanding.

2. Metal Processing

• Rust Removal and Scale Removal: Effectively remove rust and weld scale from metal surfaces using coarser grit (e.g., P60-P120).

• Weld Grinding: Grind weld seams on stainless steel, carbon steel, etc., to make them smooth and even.

• Burr Removal: Clean burrs from cutting or stamping metal parts.

• General Surface Treatment: Prepare for metal painting and spraying.

3. Automotive Repair and Body Restoration

• Sanding Putty: This is a crucial step in body restoration. The durability and cutting power of alumina sandpaper are ideal for quickly smoothing putty surfaces.

• Sanding Old Paint Layers: Sand old clear coats and color coats to increase adhesion for repainting.

The higher the number, the finer the grade.
Lower-numbered grades denote coarser sandpaper.
Medium and fine grades of sandpaper are generally used in refinishing furniture and antiques.

Medium grits, such as #120 and #150, are useful for removing old finish or scratches.
Fine grits, such as #240, are frequently used for a final light sanding just before applying stain to the wood.
