180 Grit Sanding Discs: The Ideal Choice for Pre-Finish Smoothing

180 grit sanding discs are the perfect step for creating a clean, smooth surface right before the final finishing stages. Part of the 5-Inch 8-Hole Sanding Discs, Hook & Loop, Assorted Grit (50-Pack), they provide just enough bite to refine the surface without over-polishing it, ensuring coatings adhere beautifully.

Why 180 Grit is Important

It’s the transitional grit that removes scratches left by 120 grit while still leaving a slight texture for primer, paint, or stain to grip. Skipping 180 grit can mean visible sanding marks in your final finish.

Best Uses for 180 Grit

• Furniture Prep: Smooths tables, chairs, and dressers before stain or paint.
• Cabinet Refinishing: Ideal for prepping panels and doors before primer.
• Auto Body Primer Sanding: Levels and smooths primer without cutting too deep.
• Wood Trim & Molding: Refines profiles while keeping edges crisp.

Tools & Setup

• 180 Grit Sanding Disc from the 50-Pack
• Random orbital sander with hook & loop pad
• Vacuum or dust extraction system
• Safety glasses and dust mask

Step-by-Step: Using 180 Grit

1. Prep the Surface: Start with 120 grit to remove roughness or deeper scratches.
2. Attach the Disc: Align the 8 holes for optimal dust collection.
3. Sand with Light Pressure: Let the disc cut without forcing it into the surface.
4. Overlap Each Pass: Ensures even coverage and consistent smoothness.
5. Inspect the Finish: Once smooth and uniform, you can move to 220 grit or apply finish.

Pro Tips

• Keep the sander moving to avoid swirl marks or heat spots.
• Change discs as soon as they lose cutting efficiency.
• Vacuum and tack cloth the surface before moving to finer grits or finish.

Common Mistakes

• Skipping 180 Grit: Can leave coarse scratches visible through the finish.
• Starting with 180 Grit: Not aggressive enough for heavy removal.
• Over-Sanding: Can burnish the surface, reducing finish adhesion.

FAQs

• Can I finish after 180 grit? Yes, but 220 grit will give an even smoother surface for clear finishes.
• Is it good for metal? Yes, for light refinement before paint.
• Can I use it between coats? Not recommended—use 320 grit or finer for that purpose.
