Sanding is a fundamental surface preparation technique where workers smooth out surfaces using abrasive materials like sandpaper. It's an essential step before painting or finishing, making surfaces clean and ready to accept paint or other coatings. This process can be done by hand or with power tools like orbital sanders or belt sanders. The skill level of a worker in sanding directly impacts the final quality of painting or finishing work. It's similar to other surface preparation methods like scraping or stripping, but sanding is particularly important for achieving a professional, smooth finish.
