Identify the slab and finish, inspect for resin, fissures, chips, and seams, and use a stone-professional diamond system when material removal or polish restoration...
Separate an open hole, a proud repair and a sheen mismatch on filled travertine before removing more stone.
Separate repair integrity, surface level and oil-related color before attempting to blend a sink seam.
Distinguish joint movement and coating problems from a raised machining defect; do not repeatedly flatten a moving joint.
Use inspection gates: after each grit, wipe clean and inspect under angled light. If older scratches remain, stay. This workflow sands a pine door trim to sand primer smooth for semi-gloss paint through 150–400 grit using that rule. Gates prevent...
Clean between steps to avoid random deep scratches. Dust and loose grit can re-scratch the surface and undo your progress. This workflow sands a powder-coated fence panel to scuff for recoat and improve adhesion through 120–600 grit with wipe/vacuum habits...
This is an inspection-driven workflow: sand → wipe → inspect → decide. If older scratches remain, stay at the same grit. This guide sands a chrome motorcycle exhaust tip to reduce fine scratches before polishing through 120–600 grit using that...
Focus on scratch patterns: your goal at each grit is one consistent scratch texture, then you replace it with a finer texture at the next grit. This workflow sands a aluminum pontoon railing to prep for repaint and remove oxidation...
Sanding is scratch replacement: each grit removes the previous scratch pattern and replaces it with a finer one. This workflow sands a terrazzo floor spot repair to blend sheen and reduce visible transition through 400–1500 grit by completing each replacement...
