120 Grit Sanding Discs: The Perfect Balance for Smoothing and Prep

120 grit sanding discs are the ideal choice for smoothing surfaces after coarse sanding and preparing them for finer finishes. Included in the 5-Inch 8-Hole Sanding Discs, Hook & Loop, Assorted Grit (50-Pack), they’re the bridge between aggressive material removal and detail-oriented fine sanding.

Why 120 Grit Matters

This medium-coarse grit eliminates deep scratches from 80 grit while leaving a surface that’s smooth enough for 180 grit or finer. It’s a go-to for furniture, cabinetry, and paint prep work.

Best Uses for 120 Grit

• Furniture Refinement: Smooths surfaces before staining or sealing.
• Cabinet Prep: Creates a uniform surface for primer or paint.
• Metal Prep: Cleans and levels metal before painting or polishing.
• Patch Leveling: Evens filled areas for a seamless blend.

Tools & Setup

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

Step-by-Step: Using 120 Grit

1. Prep with 80 Grit: Start with coarse sanding to remove material or old finishes.
2. Attach the Disc: Align 8 holes for maximum dust removal.
3. Sand Evenly: Use steady, overlapping passes across the surface.
4. Check Progress: Stop once coarse scratches are gone.
5. Move to 180 Grit: Refine the surface for a near-finish smoothness.

Pro Tips

• Vacuum between grits to avoid cross-contamination.
• Use light to moderate pressure for even sanding.
• Change discs as soon as they stop cutting efficiently.

Common Mistakes

• Skipping 120 Grit: Can leave deep swirl marks visible under finish.
• Over-Sanding: Can polish the wood too much, reducing stain absorption.
• Using for Heavy Removal: Not coarse enough for stripping jobs.

FAQs

• Can I finish sanding with 120 grit? Suitable for paint prep; for stain or varnish, follow with 180 or 220 grit.
• Is it safe on plastic? Yes, but apply minimal pressure to avoid heat buildup.
• Can I wet sand with 120 grit? Only if the disc is rated for wet/dry use.
