Quick Summary

Sandpaper is a material used for smoothing and polishing surfaces. It consists of abrasive particles, such as sand, glued to one side of a flexible backing, typically paper or cloth. The abrasive particles are harder than the material being worked on, allowing them to wear away the surface.12

Sandpaper is used in various applications, from household tasks to industrial manufacturing, to create smooth finishes on materials like wood, metal, and plastic. The grit size of the sandpaper determines its coarseness, with larger grits used for rougher sanding and finer grits for smoother finishes. The term "sandpapering" refers to the act of rubbing with or as if with sandpaper.234
