eQualle Sandpaper Sheets for Smoothing Drywall Seams (120–320 Grit Guide)

Finishing drywall seams requires precision to achieve smooth, paint-ready walls. eQualle 9x11 inch Wet/Dry Sandpaper Sheets provide the right grit sequence to level joint compound, feather seams, and eliminate imperfections.

Why Sanding Drywall Seams is Important

Even with skilled application, joint compound leaves ridges or uneven textures. Sanding blends these areas into the surrounding drywall, creating a seamless finish. Without proper sanding, seams will remain visible after painting.

Tools You’ll Need

• Pole sander or sanding block
• Vacuum and tack cloth
• Work light to reveal imperfections
• Dust mask and safety goggles
• eQualle Wet/Dry Sandpaper Sheets

Best Sandpaper Grits for Drywall Seams

• 120 Grit (25-pack) — Levels dried joint compound and removes ridges.
• 150 Grit (50-pack) — Smooths seams after initial sanding.
• 220 Grit (100-pack) — Blends compound into surrounding drywall.
• 320 Grit (25-pack) — Final sanding before primer and paint.

Step-by-Step: Sanding Drywall Seams

1. Inspect seams. Shine a light across the wall to highlight ridges and bumps.
2. Start with 120 grit. Sand joint compound ridges and uneven buildup.
3. Switch to 150 grit. Smooth the seam and feather edges.
4. Move to 220 grit. Blend seams into surrounding drywall for an even surface.
5. Finish with 320 grit. Lightly sand for a flawless, paint-ready wall.
6. Clean thoroughly. Vacuum and wipe down with a tack cloth before priming.

Special Cases

For ceilings, use a pole sander with light pressure to avoid gouging. For textured walls, sanding may be minimal—matching texture application is often better.

Pro Tips

• Always sand in circular motions for smooth blending.
• Don’t oversand—too much pressure exposes drywall paper.
• Use wet sanding for dust-free finishing in small spaces.

Aftercare

• Prime walls before painting to seal compound and reveal hidden flaws.
• Lightly sand primer coat with 220 grit for best paint adhesion.
• Store leftover sandpaper flat in a dry area for future touch-ups.

FAQs

• What grit is best before primer? 220–320 grit provides a smooth, ready surface.
• Can I skip sanding between coats of compound? No, light sanding ensures smooth layering.
• Should I wet sand drywall seams? Wet sanding reduces dust, but dry sanding provides better control.
