Check what recycled abrasive claims cover, separate packaging from backing, and compare waste per accepted job without unsupported promises.
Compare final sanding preparation for actual oil and waterborne finish systems using matched samples and the complete coating schedule.
Choose 400 or 500 grit for primer using the correct coating specification. Separate leveling, scratch refinement, and wet or dry methods.
Choose 120 or 150 grit for bare wood before paint. Remove the right defects, preserve edges, and verify the result with a coated sample.
Compare 1000 and 1200 grit with a controlled test patch. Check grading, the next process, and whether the intermediate step adds value.
Create sanding grit presets for recurring jobs, with clear starting conditions, finish-specific stop points, and exceptions that trigger a new test.
Compare 2000 and 3000 grit sandpaper for ultra-fine wet sanding, scratch refinement, and preparation before polishing.
Compare 800 and 1000 grit sandpaper for fine scratch refinement, wet sanding, finish checks, and preparation for the next step.
Compare 100 and 120 grit sandpaper by cutting speed, scratch pattern, surface condition, and the next step in your sanding sequence.
