Prepping Drywall Corners with 180 Grit Sandpaper Sheets

Drywall corners are one of the most challenging areas to finish smoothly. Proper sanding ensures sharp, clean lines that blend seamlessly with the rest of the wall. eQualle 180 grit sandpaper sheets (9x11 in, Wet or Dry) are excellent for this task, offering the right balance of cutting power and refinement.

Why 180 Grit for Corners?

180 grit is a medium-fine abrasive that removes ridges and smooths joint compound without damaging the drywall paper. It’s fine enough to prepare corners for primer and paint while still strong enough to level uneven spots.

Tools You’ll Need

• eQualle 180 Grit Sandpaper sheets (9x11 in, Wet or Dry)
• Sanding block or corner sanding tool
• Dust mask and goggles
• Tack cloth or vacuum with brush attachment
• Work light to check smoothness

Step-by-Step: Sanding Drywall Corners

1. Inspect the joint compound. Make sure it is fully dry before sanding.
2. Sand with 180 grit. Use 180 grit (50-pack) folded sheets or a corner sanding tool to work both sides of the corner.
3. Feather edges. Blend compound smoothly into surrounding surfaces with light, even strokes.
4. Check with light. Shine at an angle to reveal imperfections and sand again if needed.
5. Clean surface. Vacuum dust and wipe with a tack cloth before priming.

Special Cases

For rougher finishes, start with 150 grit before refining with 180. For final smoothing, follow with 220 grit before priming and painting.

Pro Tips

• Always fold sandpaper tightly to maintain crisp corner control.
• Sand lightly—too much pressure can round off the corner.
• Replace sheets often; drywall dust clogs abrasives quickly.
• Prime immediately after sanding to seal the surface.

Aftercare

• Lightly sand primer with 220 grit before applying paint.
• Store sandpaper sheets flat and dry for consistent performance.
• Inspect corners under strong light after painting for professional results.

FAQs

• Is 180 grit too coarse for corners? No—it’s the standard grit for prepping drywall corners before paint.
• Do I need a special sanding tool? Not always—folded sheets work well for most corners.
• Can I skip sanding corners? No—unsanded corners will look uneven and show through paint.
