Selecting the perfect finish for a stringed instrument is a crucial step in the luthier's process. Natural shellac has been a preferred choice for centuries, but alternative finishes such as urethane, lacquer, and oil-based options have emerged over time. In this blog post, we'll compare the pros and cons of natural shellac and its contemporaries to help you make an informed decision for your next woodworking project.

Natural Shellac


  1. Acoustic Enhancement: Shellac's thin and flexible nature allows for better resonance and improved sound quality in stringed instruments.
  2. Visual Appeal: Shellac imparts a warm, rich, and glossy finish that highlights the wood grain.
  3. Easy Repair: Shellac finishes can be easily repaired by applying another layer or re-amalgamating the existing finish with a solvent.
  4. Non-toxic and Eco-friendly: Shellac is a natural, non-toxic material, and can be dissolved using food-grade alcohol, such as Culinary Solvent.


  1. Sensitivity to Heat and Moisture: Shellac can be susceptible to damage from heat and moisture, making it less durable than some alternative finishes.
  2. Longer Drying Time: Shellac requires a longer drying time between coats compared to some modern finishes.



  1. Durability: Urethane finishes offer excellent resistance to heat, moisture, and scratches.
  2. Fast Drying Time: Urethane finishes typically dry faster than shellac, allowing for quicker project completion.


  1. Tonal Impact: Urethane's thickness and rigidity may negatively affect the instrument's natural vibrations and sound quality.
  2. Difficult Repair: Repairing urethane finishes can be more challenging, often requiring sanding or stripping.



  1. Quick Drying Time: Lacquer finishes dry quickly, making it an efficient choice for luthiers.
  2. High Gloss: Lacquer can create a high-gloss finish that many find visually appealing.


  1. Toxic Fumes: Lacquer finishes emit toxic fumes during application and drying, requiring proper ventilation.
  2. Potential for Cracking: Lacquer can become brittle over time, leading to cracking or crazing.

Oil-based Finishes


  1. Natural Look: Oil-based finishes enhance the wood grain and provide a more natural appearance.
  2. Easy Application: Oil-based finishes are generally easier to apply than other alternatives.


  1. Limited Protection: Oil-based finishes offer less protection against heat, moisture, and scratches compared to other options.
  2. Longer Drying Time: Oil-based finishes require a longer drying time between coats.
