How to Finish Butcher Block Countertops

Butcher block countertops add warmth and character to any kitchen. They are durable and can be refinished when they show wear. Finishing them properly is crucial to ensure their longevity. The process involves preparing the wood, choosing the right finish, and applying it correctly.

Preparation

Start by preparing your butcher block surface. Ensure it’s smooth and free from any imperfections. Use a random orbital sander with varying grit sandpapers.

  • Begin with coarse 80-grit sandpaper. This will remove rough spots and surface stains.
  • Switch to 120-grit sandpaper for the next round. This will smooth the surface further.
  • Finish with 220-grit sandpaper for a fine, smooth finish. Sand with the grain of the wood for best results.

After sanding, clean the countertop to remove any dust. A tack cloth works well for this purpose. Ensure that the surface is completely clean before moving on to the next step.

Choosing the Right Finish

There are several options when it comes to finishing butcher block countertops. The choice depends on the desired look and the level of protection needed.

  • Mineral Oil: This is a popular option because it’s food-safe and easy to apply. It’s ideal for countertops that are heavily used for food preparation.
  • Tung Oil or Linseed Oil: Both are natural oils that penetrate deeply into the wood, providing durable protection. They are also food-safe once cured.
  • Polyurethane: For a durable, water-resistant finish, polyurethane is an excellent choice. However, it’s not food-safe unless specified, so may not be suitable for surfaces used directly for food prep.
  • Waterlox: This is a mix of tung oil and resin that provides a tough, waterproof finish. It’s suitable for high-use surfaces but requires proper ventilation during application.

Application Process

The application process varies slightly depending on the type of finish chosen. Here’s a step-by-step guide for each type.

Applying Mineral Oil

  • Pour a generous amount of mineral oil onto the countertop.
  • Use a clean cloth to rub the oil into the wood, moving with the grain.
  • Allow the oil to soak in for about 20 minutes.
  • Wipe off any excess oil with a dry cloth.
  • Repeat this process once a day for a week, once a week for a month, and then once a month thereafter to maintain the finish.

Applying Tung Oil or Linseed Oil

  • Thin the first coat of oil with an equal part of mineral spirits. This helps the oil penetrate the wood.
  • Apply the oil mixture with a clean cloth, following the wood grain.
  • Allow it to penetrate the wood for about 15 minutes before wiping off any excess.
  • Let the surface dry for 24 hours.
  • Apply subsequent coats of pure oil, allowing each coat to dry fully before applying the next. Usually, three to five coats are sufficient.

Applying Polyurethane

  • Stir the polyurethane to mix the contents. Avoid shaking, as this can create bubbles.
  • Use a high-quality brush or foam applicator to apply a thin, even coat.
  • Allow the first coat to dry completely, typically about four hours.
  • Lightly sand the surface with 320-grit sandpaper to remove imperfections.
  • Wipe the surface clean with a tack cloth.
  • Apply two to three more coats, sanding between coats. Allow each coat to dry before sanding and reapplying.

Applying Waterlox

  • Apply Waterlox using a high-quality natural bristle brush or lint-free cloth.
  • Follow the wood grain, applying a thin and even layer.
  • Allow the first coat to dry for 24 hours.
  • Sand the surface lightly with 320-grit sandpaper.
  • Wipe clean with a tack cloth.
  • Apply multiple coats as needed, typically three to four. Let each coat dry thoroughly before applying the next.

Maintaining Your Butcher Block Countertops

Proper maintenance can extend the life of your butcher block countertops. Regularly cleaning and reapplying finish will keep them looking their best.

  • Wipe down the countertop after each use with a damp cloth and mild soap.
  • Avoid soaking the wood with water or using harsh chemicals.
  • Regularly reapply the chosen finish as needed. For mineral oil, this might be monthly. For other finishes, it could be yearly.
  • Use cutting boards for food prep to prevent knife marks and other damage.

Inspect the surface periodically for any signs of wear or damage. Addressing issues early will prevent them from becoming major problems.
