What the AI looks for in Sanding Blocks
- Rigid versus flexible
- Rigid blocks for flat surfaces and edges, foam for contours and profiles Soft blocks round over edges you want crisp.
- Abrasive attachment
- Hook-and-loop, clamp or adhesive must match the paper you buy This determines ongoing cost and how easy refills are.
- Grit progression
- Do not skip more than one grit step Skipping leaves scratches from the coarser grit.
- Clog resistance
- Open-coat or anti-load abrasives for paint and filler Loaded abrasive stops cutting.
Brands that matter
- 3M: Sanding sponges and blocks.
- Mirka: Professional finishing abrasives and blocks.
- Hyde: Painting and drywall prep tools.
- Norton: Abrasives and blocks.
What to avoid
- Sanding a flat surface with your hand alone, which leaves dips
- Foam blocks on edges that should stay sharp
