Sandpaper Grit Guide
About This Tool
Selecting correct sandpaper grit sequences is crucial for professional-quality finishes. Our Sandpaper Grit Guide recommends optimal progressions based on project type, wood species, and desired finish quality.
Understanding Grit Numbers
Grit numbers indicate abrasive particle size per square inch. Higher numbers mean finer particles:
- Coarse (40-60): Initial smoothing, scratch removal
- Medium (80-120): General sanding, finish prep
- Fine (150-180): Final sanding before staining
- Very Fine (220-320): Between coats, final smoothing
Project-Specific Progressions
Furniture Refinishing
- Start: 80 grit (removing old finish)
- Progress: 120 → 150 → 220 grit
- Final: 220 grit before staining
New Wood Preparation
- Rough lumber: 80 → 120 → 180 → 220
- Smooth lumber: 120 → 180 → 220
Wood Species Considerations
- Hardwoods (Oak, Maple): Can handle aggressive starting grits
- Softwoods (Pine, Cedar): Start with finer grits to avoid fuzzing
