What is wet sanding?

• A. Sanding with water to reduce dust and scratches
• B. Sanding without water
• C. Sanding with solvent
• D. Sanding with air

Answer: (A)

Wet sanding means sanding with water present to lubricate the abrasive as you work. The water helps carry away the grit and debris, which keeps the surface from clogging the paper and reduces heat buildup that can cause finishing damage. This lubrication also minimizes dust and helps you achieve a smoother, finer finish by allowing the abrasive to cut more evenly. In auto refinishing, water is often used when smoothing panels or blending finishes to prepare for paint, especially with fine grits. Dry sanding, by contrast, kicks up a lot more dust and can heat the surface more quickly, while using solvents or air isn’t the definition of wet sanding. So the idea behind wet sanding is sanding with water to reduce dust and scratches.
