DIY Dammar Varnish Matte Finish for Oil Paintings: A Comprehensive Guide

If you are looking to achieve a matte finish on your oil paintings, there are a few methods you can consider. This article will guide you through the process of creating your own Dammar varnish matte finish from the comfort of your home. We will cover the traditional methods and the modern approach, ensuring that you can choose the best option for your painting style and requirements.

Traditional Method: Using Matting Agents

The traditional method for achieving a matte finish in oil painting involves the use of matting agents. If you're using Dammar, a popular varnish, you are likely a traditionalist who values the natural and time-honored techniques. In this case, a traditional matting agent is the right choice:

Powdered Calcium Carbonate (Whiting/Marble Dust): Available from art supply houses, professional paint/finish stores, and ceramic supply houses. Superfine silica sand dust is another alternative that can be found at marine supply houses, typically as an adjunct to epoxy finish systems.

These agents are mixed with the varnish to create a matte finish. Simply add a small amount of matting agent to your Dammar varnish and mix it gently to achieve the desired opacity and texture.

Modern Method: Using Matting Resins and Chemicals

For those who prefer a more contemporary approach, there are modern matting agents made from plastic resins and chemicals. However, determining which product will work best with your Dammar varnish may require some research and outside assistance. This method can be more complex, but it offers a wider range of options for achieving the perfect matte finish.

Option for Easier Matte Finish: Combining Dammar Varnish with Wax Medium

Another method to achieve a matte finish without the hassle of mixing powdered agents is to use a wax medium. By combining Dammar varnish with Dorland's wax medium, you can achieve a less shiny finish that not only looks matte but also provides added protection to your artwork. Adding a small amount of linseed oil and turpentine can further enhance the semi-matte quality of the painting medium. This method is quick, easy, and requires minimal materials, making it an excellent choice for artists looking for a more convenient solution.

Step-by-Step Guide to Making Your Own Dammar Varnish

If you prefer to make your own Dammar varnish, here's a step-by-step guide to help you achieve the desired results:

Prepare Your Materials: Ensure you have the necessary tools and materials, including 200 ml gum turpentine and 100 grams of Dammar gum resin chunks. Safety Precautions: Always wear protective gloves and use a well-ventilated area when working with strong solvents like gum turpentine. Ensure the room is well-ventilated to avoid inhaling harmful fumes. Fill Pantyhose: Fill a pair of pantyhose with the Dammar gum resin chunks to create a reservoir for the varnish. Infuse Turpentine: Pour 200 ml of gum turpentine into a glass jar and place the filled pantyhose with resin chunks inside. Use the jar lid to secure the pantyhose in place from the inside. Allow Resin to Infuse: Let the pantyhose sit in the turpentine for several hours or overnight to allow the resin to fully infuse the fluid. Strain the Varnish: After the resin has infused, strain the varnish through a fine sieve or cheesecloth to remove any remaining chunks and debris. Adjust Varnish Consistency: Depending on your desired consistency, you can add a small amount of linseed oil and turpentine to adjust the viscosity. Mix well to ensure an even consistency. Storage: Store the varnish in a clean, airtight container in a cool, dark place. It is best to use it within a month to ensure optimal quality.

By following these steps, you can create your own custom Dammar varnish. Whether you choose the traditional or modern approach, the key is to experiment and find the method that best suits your painting style and preferences.

Remember, achieving a perfect matte finish can take some practice and adjustments. Don't be discouraged if the first few attempts don't yield the desired results. Keep experimenting and refining your technique to create the perfect matte finish for your oil paintings.
