Tinting varnish is a process of adding color to varnish to achieve a desired shade. There are a few methods for tinting varnish, including using oil-based or universal colorants, mixing in pigments, or using pre-tinted varnish. To tint varnish, start by selecting the desired color and type of colorant. Mix the colorant into the varnish slowly, stirring thoroughly to ensure even distribution. Test the tinted varnish on a small area before applying it to the entire surface. Make any necessary adjustments to achieve the desired shade. Tinting varnish can add depth and character to wood finishes and is a great way to customize your project.
Adding color to varnish is a common practice. Tinted varnish is a type of glaze that is used to add tone and color to woodwork and painted surfaces. It is possible to tint both water- and oil-based varnishes, as well as create glazes using other finish materials like lacquer and shellac.
There are multiple methods for tinting varnish. One option is to mix it with a stain that has the desired color. Artists’ pigments, such as cadmium red or cobalt green, can also be used. However, the easiest approach is to use universal colorants that can be found at any paint store. These colorants are compatible with both oil- and water-based finishes and are cost-effective. Alternatively, pre-tinted varnishes can be purchased online or at paint stores and home improvement outlets.
Mixing Varnish With Stain
Mixing varnish with stain is a viable option, but it has its limitations. The stain concentration should not exceed 20 percent, as it can compromise the protective qualities of the varnish film. However, if the concentration is exceeded, it will create a wiping varnish that penetrates the wood pores, which can be advantageous in certain situations. Additionally, regardless of the mix ratio used, the final color will always be lighter than the stain color.
It is important to mix stains and varnishes from the same manufacturer and ensure they have the same solvent base, as oil and water do not mix. The two products should be mixed in a separate container to the desired ratio and stirred well. It may be necessary to stir frequently during application to prevent the pigments from settling.
Advantages of Using Pigments and Colorants
The primary advantage of tinting varnish with universal colorants or artists’ pigments is the ability to create custom colors without limitations on hue intensity. By adding enough colorant, the finish can become nearly opaque, although its translucent quality will always remain due to the clear base of varnish.
Earth tones, such as raw and burnt sienna, and raw and burnt umber, are commonly used for tinting varnish. However, primary colors like reds, greens, and blues can also be included for a unique and vibrant look. Tinting varnish with primary colors can rejuvenate furniture and add new life to pieces painted with the same colors used for tinting.
Tips for Tinting Varnish With Colorants
When tinting varnish with pigments and colorants, remember that a little goes a long way. Even a few drops of colorant or small amounts of powdered pigment can have a significant impact. Since there is no computer to guide the process like at a paint store, experimentation is necessary. It is recommended to work with a sample before tinting the entire batch of varnish.
Stick with one color
Generally, it is advisable to stick with a single color as mixing colors does not always result in the desired hue. If you must mix colors, it is more reliable to create two separate samples of different colors and blend them together, rather than combining two colorants or pigments in one sample. If you are aiming for a specific hue, it is recommended to have the varnish tinted at a paint store where a computer can suggest the precise proportions of pigments needed to achieve it.
