Sanding Plaster Walls Smooth with 220 Grit Sandpaper Sheets

Plaster walls add character and durability to homes, but imperfections like trowel marks, ridges, or repairs often need smoothing before painting. eQualle 220 grit sandpaper sheets (9x11 in, Wet or Dry) are ideal for finishing plaster surfaces, leaving them smooth and paint-ready.

Why 220 Grit for Plaster?

220 grit is a fine abrasive that gently levels plaster without scratching or gouging. It’s coarse enough to remove minor ridges and smooth repairs while being fine enough to leave a clean surface for primer and paint adhesion.

Tools You’ll Need

• eQualle 220 Grit Sandpaper sheets (9x11 in, Wet or Dry)
• Sanding block or pole sander
• Dust mask and safety goggles
• Vacuum with brush attachment
• Tack cloth or microfiber rag

Step-by-Step: Sanding Plaster Walls

1. Inspect the wall. Look for raised edges, tool marks, or patch repairs.
2. Sand with 220 grit. Use 220 grit (100-pack) sheets with light, even strokes to smooth imperfections.
3. Feather repairs. Blend patched areas into surrounding plaster for a seamless finish.
4. Check progress. Shine a work light across the wall to reveal missed spots.
5. Clean thoroughly. Vacuum and wipe with a tack cloth before priming or painting.

Special Cases

For heavily textured plaster, start with 180 grit before refining with 220. For delicate or thin plaster layers, use minimal pressure to avoid sanding through.

Pro Tips

• Always sand in wide, overlapping strokes for uniform results.
• Replace clogged sheets often—plaster dust builds up quickly.
• Work slowly and inspect frequently under angled light.
• Prime immediately after sanding to seal the plaster surface.

Aftercare

• Lightly sand primer with 220 grit before painting for the smoothest finish.
• Store sandpaper flat and dry to prevent curling.
• Dispose of used sheets—plaster dust reduces their effectiveness quickly.

FAQs

• Is 220 grit too fine for plaster? No—it’s perfect for final finishing before painting.
• Do I need to sand all plaster walls? Only if imperfections are visible or repairs were made.
• Can I wet sand plaster? It’s not recommended—plaster softens when wet.
