Sanding Wooden Countertops: Grit Guide for a Durable, Smooth Finish

Wooden countertops bring warmth and character to kitchens, but to keep them looking their best, proper sanding is essential. Whether you’re installing new butcher block or refinishing an old top, following the correct grit sequence ensures durability and a silky smooth finish.

Why Sand Wooden Countertops?

Sanding removes scratches, old finishes, and imperfections while preparing the surface for oil, stain, or sealant. Without sanding, finishes may look uneven and won’t fully protect the wood from moisture and daily wear.

Tools You’ll Need

• Sandpaper sheets in multiple grits
• Orbital sander or sanding block
• Vacuum and tack cloth
• Protective gear (mask, safety glasses)
• Wood oil, stain, or sealer

Best Grit Sequence for Countertops

• 80 grit: Removes old finish and deep scratches.
• 120 grit: Smooths the surface after coarse sanding.
• 180 grit: Refines scratches and preps for finish.
• 220 grit: Final sanding before applying oil or sealant.

Step-by-Step: Sanding Wooden Countertops

1. Prep the surface. Clear the countertop and clean off dirt and grease.
2. First sanding pass. Use 80 grit (50-pack) to strip old finish and level scratches.
3. Smooth with 120 grit. Switch to 120 grit (25-pack) for a more consistent surface.
4. Refine with 180 grit. Apply 180 grit (100-pack) to prepare wood for finishing.
5. Final sanding. Use 220 grit (25-pack) for a smooth, finish-ready surface.
6. Clean thoroughly. Vacuum dust and wipe with a tack cloth.
7. Apply finish. Use oil for a natural look, stain for color, or sealer for maximum protection.

Special Cases

For butcher block, consider sanding up to 320 grit if you want a polished surface. For countertops near sinks, always use a waterproof sealer after sanding.

Pro Tips

• Always sand with the grain to avoid cross scratches.
• For edge grain butcher block, pay attention to seams to keep them level.
• Raise the grain with a damp cloth before final sanding for better oil absorption.

Aftercare

• Reapply oil or sealer every 6–12 months depending on use.
• Clean with mild soap and water—avoid harsh chemicals.
• Lightly sand with 220 grit before re-oiling to refresh the surface.

FAQs

• Do I need to sand the entire countertop? Yes—spot sanding can create uneven absorption and color.
• Can I stop at 180 grit? Yes, if staining. For clear oil finishes, 220 grit gives a smoother result.
• What if my countertop feels rough after finishing? Lightly sand with 320 grit and reapply oil or sealer.
