How to Sand Wood for a Butcher Block Countertop: Smooth, Safe, and Ready to Seal

Sanding is the most critical step in preparing a butcher block countertop for sealing, staining, or oiling. Whether you’ve just installed a new one or are restoring an old block, proper sanding ensures a food-safe, splinter-free surface that highlights the beauty of natural wood. This SEO-rich guide covers the best sandpaper grits and methods to get your butcher block smooth, clean, and ready for use.

Why Sand a Butcher Block Countertop?

Butcher blocks are used for food prep, so the surface must be smooth, sanitary, and well-sealed. Sanding removes factory coatings, scratches, and roughness before applying finish or oil.

Best Sandpaper Grits for Butcher Block

• 80–120 grit sandpaper: For leveling the surface and removing existing finish or mill marks.
• 150–180 grit sandpaper: For general smoothing before sealing or oiling.
• 220–320 grit sandpaper: For ultra-smooth final passes and between finish coats.

Step-by-Step: How to Sand a Butcher Block Countertop

1. Clean the surface and make sure it’s completely dry.
2. Start with 80–120 grit to level and remove any existing finish.
3. Move to 150–180 grit for general prep and smoothing.
4. Finish with 220–320 grit for a silky, clean finish before sealing or oiling.
5. Wipe off dust with a tack cloth before applying finish or mineral oil.

Tips for a Food-Safe Finish

• Always sand with the wood grain for best results.
• Use food-safe oils like mineral oil or beeswax after sanding.
• Don't over-sand if you plan to stain—ultra-smooth wood may resist absorption.
