Understanding the Types of Shellac

Shellac is a versatile material that is widely used in woodwork projects. It is important to understand the different types of shellac available in the market and their specific applications. This section will explore the various types of shellac and highlight the differences between dewaxed and waxed shellac.

Dewaxed Shellac

Dewaxed shellac is a popular choice among woodworkers due to its versatility and compatibility with other finishes. It has had its natural wax removed, which allows it to adhere well to a variety of surfaces, including those that have been previously finished or painted. Dewaxed shellac dries clear and can be further enhanced with additional coats for a glossy finish.

One of the main advantages of dewaxed shellac is that it does not react with finishes that contain oils such as polyurethane or oil-based varnishes. This makes it an excellent choice for sealing wood before applying these other finishes. Additionally, dewaxed shellac can be easily stripped or sanded if needed, providing flexibility for future refinishing projects.

Waxed Shellac

Waxed shellac contains natural wax, which gives it a softer texture and a warm glow when applied to wood surfaces. The wax content in this type of shellac provides additional protection against moisture and stains, making it ideal for use on furniture or other wooden items that may be exposed to spills or regular use.

However, it is important to note that using waxed shellac as a sealer coat under other finishes can cause adhesion issues due to its waxy surface. Therefore, if you plan on applying polyurethane or similar finishes over the shellacked surface, it is recommended to use dewaxed shellac instead.

It’s worth mentioning that both types of shellac can come in different shades ranging from light amber to dark orange tints. These shades are caused by the impurities found in the shellac resin and can be used to enhance the natural color of wood or to achieve a specific aesthetic.

By understanding the differences between dewaxed and waxed shellac, woodworkers can choose the most appropriate type for their project and achieve the desired results. Whether it’s for sealing, enhancing, or adding a protective finish to woodwork, shellac offers a wide range of possibilities.

Preparing the Wood for Shellac Application

When it comes to using shellac in woodwork projects, proper preparation of the wood surface is essential. This section will guide you through the necessary steps to ensure that your wood is ready for shellac application.

Sanding the Wood

Before applying shellac, it is crucial to sand the wood surface to achieve a smooth finish. Start with a coarse-grit sandpaper and gradually work your way up to a finer grit. This will help remove any imperfections, such as scratches or rough patches. Sanding also helps open up the pores of the wood, allowing the shellac to penetrate better.

Cleaning the Surface

After sanding, it’s important to clean the wood surface thoroughly. Use a clean cloth or tack cloth to remove any dust or debris left from sanding. Make sure every nook and cranny is free of particles that might cause bumps or unevenness in the final finish.

Ensuring a Clean Environment

In addition to cleaning the wood itself, it’s crucial to ensure that your workspace is also clean and free from dust and dirt. Cover nearby surfaces and sweep or vacuum the area before starting the application process. This will help prevent particles from settling onto your freshly applied shellac.

Tips for Achieving a Smooth Surface

To achieve an even and smooth surface with your shellac finish, consider using a technique called “French polishing.” This involves applying thin layers of shellac using a pad made of cotton or linen wrapped in cheesecloth. The repetitive motion of applying thin coats with this method can help create a glossy and flawless finish.

Remember that proper preparation is key in achieving professional-looking results with shellac on woodwork. Take your time during this step and ensure that all surfaces are sanded, cleaned, and free from any debris before proceeding to the next section on mixing and preparing the shellac solution.

Mixing and Preparing the Shellac Solution



When it comes to using shellac for woodwork, it is essential to properly mix and prepare the shellac solution. This step ensures that you achieve the desired outcome and get a smooth, even finish on your wood surfaces. Here are some guidelines to help you with this process:

  1. Choose Your Shellac: There are two main options when it comes to shellac – flakes or pre-mixed solutions. Some woodworkers prefer to use flakes as they can have more control over the concentration of shellac in the mixture. Others find it more convenient to purchase pre-mixed shellac solutions, which eliminate the need for measuring and mixing ratios.
  2. Mixing Ratios: If you choose to use shellac flakes, you will need to mix them with denatured alcohol to create a usable solution. The ratio of flakes to alcohol will vary depending on the type of coat you want to apply.
    For a sealer coat, typically a 2-pound cut (2 pounds of flakes dissolved in 1 gallon of alcohol) is thinned with an equal amount of alcohol. For a finish coat, a full-strength 3-pound cut (3 pounds of flakes dissolved in 1 gallon of alcohol) is commonly used.
  3. Alternative Options: If measuring out ratios or mixing your own solution is not your preference or if you are new to working with shellac, there are ready-to-use options available in the market. These products come pre-mixed and are ready for immediate application.
