How to Sand Wooden Sideboards Before Refinishing

Wooden sideboards add function and style to dining and living rooms, but scratches, stains, and dull finishes can make them look worn. Sanding before refinishing restores smoothness and prepares the surface for stain, oil, or paint. This guide explains how to sand sideboards effectively for a refreshed, elegant look.

Why Sideboard Sanding Matters

Sideboards often have large flat tops, drawers, and doors. Without sanding, new finishes won’t adhere properly, leading to blotchy results or premature peeling. Proper sanding ensures even absorption and a professional-quality finish.

Tools You’ll Need

• Random orbital sander for flat surfaces
• Sanding blocks and sponges for corners and trim
• Wet/dry sandpaper sheets (80–220 grit)
• Vacuum and tack cloth
• Stain, paint, or oil finish

Best Grit Sequence for Sideboards

• 80 grit: Removes old finish, scratches, and dents.
• 150 grit: Smooths surfaces and prepares for finer sanding.
• 220 grit: Final pass for stain, oil, or paint readiness.

Step-by-Step: Sanding Wooden Sideboards

1. Prep sideboard. Remove drawers, shelves, and hardware. Clean thoroughly.
2. Initial sanding. Start with 80 grit (25-pack) to strip old coatings and smooth damage.
3. Smooth surfaces. Switch to 150 grit (50-pack) for even surface preparation.
4. Final prep. Use 220 grit (100-pack) to create a finish-ready surface.
5. Clean thoroughly. Vacuum and wipe with tack cloth before finishing.

Special Cases

For veneer sideboards, sand lightly to avoid damaging thin layers. Antique pieces should be sanded by hand to preserve details. Painted sideboards may need chemical stripping before sanding to prevent clogging paper.

Pro Tips

• Sand with the grain for consistent results.
• Work in sections—top, sides, and doors separately for better control.
• Test stain or paint on an inside drawer before applying to the full piece.

Aftercare

• Protect finish: Use coasters and mats to prevent water damage.
• Re-finish as needed: Light sanding with 220 grit before re-coating extends lifespan.
• Clean gently: Avoid harsh cleaners that break down finishes.

FAQs

• Do I need to sand to bare wood? Yes, if the old finish is failing. For light touch-ups, scuff sanding may suffice.
• What finish is best? Oils highlight grain, stains add depth, and paints provide bold coverage.
• Can I sand sideboards by hand? Yes—for edges and detailed areas, hand sanding is recommended.
