How to Sand Wooden Benchtops Before Refinishing

Wooden benchtops are durable and stylish, but over time scratches, stains, and worn finishes appear. Sanding is the first step in refinishing, ensuring smoothness and proper adhesion for oils, sealers, or stains. This guide explains how to sand benchtops effectively for a refreshed and long-lasting finish.

Why Benchtop Sanding Matters

Benchtops face constant use—food prep, tools, or daily wear. Without sanding, new finishes won’t bond evenly, leading to blotches or peeling. Proper sanding restores smoothness and prepares the surface for protective coatings.

Tools You’ll Need

• Random orbital sander for large surfaces
• Sanding block for edges and corners
• Wet/dry sandpaper sheets (80–400 grit)
• Vacuum and tack cloth
• Food-safe oil, stain, or sealer

Best Grit Sequence for Benchtops

• 80 grit: Removes scratches, stains, and old finishes.
• 150 grit: Smooths the surface after coarse sanding.
• 220 grit: Prepares wood for finishing.
• 400 grit: Optional for silky smooth benchtops.

Step-by-Step: Sanding Wooden Benchtops

1. Clear and clean. Remove all items and wipe surfaces free of dust and dirt.
2. Initial sanding. Start with 80 grit (25-pack) to strip old finishes and level the surface.
3. Smooth passes. Use 150 grit (50-pack) to refine surfaces evenly.
4. Finish prep. Move to 220 grit (100-pack) for a finish-ready surface.
5. Optional polish. Sand with 400 grit for an extra smooth surface before applying oil or sealer.
6. Clean thoroughly. Vacuum and tack cloth to remove all dust before applying finish.

Special Cases

For end-grain benchtops, sanding may take longer and require extra passes. For heavily stained benchtops, spot sanding with coarse grit may be necessary before progressing to finer sanding.

Pro Tips

• Sand with the grain to avoid scratches showing under finish.
• Use light pressure to keep surfaces even.
• Wipe with mineral spirits to preview how wood will look with finish applied.

Aftercare

• Maintain finish: Reapply oil or sealer regularly depending on use.
• Spot sand: Use 220 grit to smooth out small scratches before recoating.
• Protect surfaces: Use cutting boards and coasters to extend finish life.

FAQs

• Do I need to sand to bare wood? Yes, if old finish is failing. For light updates, scuff sanding may suffice.
• What finish works best? Food-safe oils and sealers are best for kitchen benchtops.
• Can I sand by hand? Yes, but power sanders save time on large surfaces.

Watch & Learn

Sanding benchtops is the foundation of long-lasting refinishing. With the right grit sequence and tools, you’ll restore beauty and durability to your benchtops for years of use.
