Which statement best defines block sanding?

• A. It involves using a sanding block to create a flat, even surface
• B. It uses only power tools
• C. It ignores flatness
• D. It is identical to feather edging

Answer: (A)

Block sanding centers on using a sanding block to keep the abrasive surface flat against the work so material is removed evenly and the area lies in a uniform, flat plane. This approach prevents gouges and uneven curves and helps the repair blend smoothly with surrounding panels. The block can be used by hand or with a powered block, but the defining feature is the flat, consistent contact that distributes pressure evenly. It’s not limited to power tools, and flatness is the goal, not something to ignore. It’s also not the same as feather edging, which is about tapering edges to blend paint transitions, not maintaining a flat sanding plane.
