Term: sanding

Sanding is the process of smoothing or preparing a surface—typically wood, plaster, metal, or painted surfaces—by rubbing it with an abrasive material such as sandpaper or a mechanical sander. In painting and decorating, sanding is a crucial step used to:

• Remove old paint, varnish, or imperfections
• Smooth out surface irregularities
• Create a key (slightly roughened surface) to help new paint or coatings adhere properly
• Level filler or patching compounds

Sanding can be done manually using sanding blocks or sheets, or with power tools like orbital or belt sanders, depending on the size and nature of the job. Proper sanding ensures a high-quality, professional finish in painting and surface preparation.
