Sanding Drywall Joints with eQualle Sandpaper Sheets (9x11 in, 120–400 Grits)

Perfectly smooth drywall is the foundation of a professional-looking wall finish. Whether you’re patching holes or finishing new drywall, sanding is essential. Using eQualle Sandpaper Sheets (9x11 inches) ensures consistency and durability for this dusty but critical task.

Why Sanding Drywall Joints Matters

Sanding evens out joint compound, blends seams, and prepares the surface for paint. Skipping or rushing this step can leave bumps, ridges, and visible seams that ruin the final look.

Tools You’ll Need

• eQualle Sandpaper Sheets, 9x11 in
• Drywall sanding block or pole sander
• Dust mask and safety goggles
• Vacuum or damp cloth
• Primer and paint

Recommended Grit Sequence

• 120 Grit (100-pack) — For rough shaping and leveling fresh joint compound.
• 220 Grit (25-pack) — Smooths ridges and feathers edges for blending.
• 320 Grit (50-pack) — Refines the surface for primer.
• 400 Grit (25-pack) — Final pass before painting for an ultra-smooth wall.

Step-by-Step Drywall Sanding

1. Inspect joints. Ensure joint compound is completely dry before sanding.
2. Rough shaping. Use 120 grit to knock down high spots and uneven seams.
3. Blend edges. Move to 220 grit to feather the joint edges into the surrounding drywall.
4. Refine surface. Sand with 320 grit to eliminate minor imperfections.
5. Final smooth pass. Finish with 400 grit for a seamless surface ready for primer.
6. Clean thoroughly. Wipe with a damp cloth or vacuum dust before priming.

Special Cases

For ceilings, always use a pole sander to maintain even pressure. For spot repairs, a small sanding block gives better control.

Pro Tips

• Shine a work light across the wall to highlight imperfections before painting.
• Use light pressure—pressing too hard can damage the drywall paper.
• Sand in a circular motion on patched areas for better blending.
• Always wear a dust mask; drywall dust is extremely fine.

Aftercare

• Prime immediately after sanding to seal dust.
• Apply two coats of paint for best coverage on fresh drywall.
• Use a washable paint finish in high-traffic areas for easier maintenance.

FAQs

• Can I skip the 400 grit? Yes, but it provides the smoothest results, especially with glossy paint.
• Should I wet sand drywall? Wet sanding reduces dust but is less precise—use only for small touch-ups.
• Why is my wall still rough after sanding? Likely because the compound wasn’t fully dry or sanding skipped grit steps.
