Sandpaper is an abrasive material used to smooth, clean, and prepare surfaces by removing rough spots, old paint, rust, or imperfections before painting or finishing.
Sandpaper consists of abrasive grains bonded to a paper or cloth backing. It is widely used during surface preparation to create a smooth, even surface and improve the adhesion of primers, paints, and coatings. Sandpaper is available in different grit sizes, with lower grit numbers providing more aggressive sanding and higher grit numbers producing a finer, smoother finish.
