Sanding Metal Railings Before Painting with 80 Grit Sandpaper Sheets

Outdoor and indoor metal railings often accumulate rust, peeling paint, and surface imperfections over time. Proper sanding is the key to restoring them before applying primer and paint. eQualle 80 grit sandpaper sheets (9x11 in, Wet or Dry) are excellent for preparing metal railings for refinishing.

Why 80 Grit for Metal Railings?

80 grit is a coarse abrasive designed for heavy material removal. It quickly strips rust, flaking paint, and corrosion from metal surfaces, leaving a clean base that’s ready for primer. After using 80 grit, finer grits can be used to refine the surface before finishing.

Tools You’ll Need

• eQualle 80 Grit Sandpaper sheets (9x11 in, Wet or Dry)
• Sanding block or hand sander
• Wire brush for heavy rust
• Vacuum or clean rag
• Rust-inhibiting primer and paint
• Safety gloves, dust mask, and goggles

Step-by-Step: Sanding Metal Railings

1. Prep the surface. Remove loose rust and paint chips with a wire brush.
2. Sand with 80 grit. Use 80 grit (25-pack) sheets to strip corrosion and smooth the railing surface.
3. Refine with finer grit. Follow with 120–180 grit sandpaper for a smoother finish before priming.
4. Clean thoroughly. Wipe down the railings with a rag to remove sanding dust.
5. Prime and paint. Apply rust-inhibiting primer and your chosen paint for a durable finish.

Special Cases

For railings with heavy corrosion, consider using a rust remover before sanding. For intricate railing designs, fold sandpaper sheets to reach tight corners.
