Sandpaper

Sandpaper is made by bonding abrasive grains to a paper, cloth, or film backing. It is an essential surface preparation material used to smooth wood, metal, drywall, plaster, and painted surfaces. Sandpaper creates a clean, even texture that improves the adhesion of primers, paints, and coatings. It is available in different grit sizes, with lower grits for aggressive material removal and higher grits for fine finishing.Common Types

1. Aluminum Oxide Sandpaper – Durable and suitable for wood, metal, and painted surfaces.
2. Silicon Carbide Sandpaper – Ideal for wet sanding, automotive work, and fine finishing.
3. Sanding Sponge – Flexible abrasive tool for sanding corners, edges, and curved surfaces.
