120 Grit Sanding Discs: The Essential Mid-Stage for Smooth, Even Surfaces

120 grit sanding discs strike the perfect balance between material removal and surface refinement. Found in the 5-Inch 8-Hole Sanding Discs, Hook & Loop, Assorted Grit (50-Pack), these discs are the go-to choice after coarse sanding to smooth the surface and prepare it for finer grits.

Why 120 Grit is a Key Step

It removes the deep scratches left by 80 grit while leaving just enough texture for higher grits to work efficiently. This makes it an essential transitional stage in the sanding process.

Best Uses for 120 Grit

• Furniture Refinement: Smooths tables, cabinets, and shelves after initial shaping.
• Paint Preparation: Creates a uniform surface for primer and topcoats.
• Metal Smoothing: Levels surfaces before finer sanding or polishing.
• Filler Leveling: Evens out patched areas for a seamless finish.

Tools & Setup

• 120 Grit Sanding Disc from the 50-Pack
• Random orbital sander with hook & loop pad
• Dust collection system or shop vacuum
• Dust mask and safety glasses

Step-by-Step: Using 120 Grit

1. Start Prepared: Sand first with 80 grit to remove rough imperfections.
2. Attach the Disc: Align holes for optimal dust collection.
3. Sand Evenly: Keep steady, overlapping passes across the work surface.
4. Check Progress: Stop when coarse scratches are gone.
5. Move to 180 Grit: Refine further for a pre-finish surface.

Pro Tips

• Vacuum and wipe down surfaces between grits.
• Use light to moderate pressure for consistent results.
• Replace discs when they stop cutting efficiently.

Common Mistakes

• Skipping 120 Grit: Can leave swirl marks or scratches in the finish.
• Over-Sanding: May close the wood grain and reduce stain absorption.
• Using on Heavy Removal: Not coarse enough for major stripping or leveling.

FAQs

• Can 120 grit be used for final sanding? For paint prep, yes. For staining, follow with 180 or 220 grit.
• Is it safe on plastic? Yes, but use light pressure to avoid melting.
• Can it be used wet? Only if the disc is rated for wet/dry sanding.
