The Best Varnish for Gouache Paint: Tips and Applications

When selecting a varnish for gouache paint, it's crucial to understand the unique characteristics of this water-based medium. Gouache allows for reactivation even after it dries, making it sensitive to certain finishes. Fortunately, several varnishes are well-suited for protecting your gouache artwork. Let's explore the best options and application tips to ensure your artwork remains vibrant and protected.

Suitable Varnishes for Gouache Paint

When it comes to varnishing gouache paint, there are a few key types that stand out:

Acrylic Varnish

A water-based acrylic varnish is often recommended for gouache. Look for a varnish labeled specifically for acrylics, as it will have the right balance to protect your water-based medium without causing any issues.

Spray Varnish

A spray acrylic varnish can provide a seamless, even coat without disturbing the underlying paint. It's particularly useful for achieving a consistent finish across a large surface area. Make sure to choose a spray product that is specifically formulated for use with water-based media.

Retouch Varnish

If you need to make adjustments to your work or intend to continue working on it, a retouch varnish can be a temporary solution. This type of varnish is easier to remove if needed, allowing you to continue refining your art without permanent alterations.

Final Varnish

For a final protective layer, opt for a varnish that is designed for permanence and UV protection. This will ensure your artwork remains vibrant and protected over time.

Application Tips

Testing First

Always test the varnish on a small area or a separate piece before applying it to the entire artwork. This will help you determine the compatibility and desired finish. Some varnishes might affect the color or texture of the paint, so it's best to assess the outcome on a small scale.

Multiple Coats

Apply multiple thin coats of varnish rather than a single thick layer. A thick coat can disrupt the underlying paint and may not adhere as well. Thin coats allow for better adhesion and a more natural finish.

Drying Time

Allow adequate drying time between coats to ensure optimal adhesion and finish. The drying time will depend on the specific varnish product, so be sure to follow the manufacturer's guidelines for best results.

According to Lena, the varnish process greatly enhances the appearance of her gouache paintings, making them look like oil paintings. The colors become more vibrant and deep after varnishing, which can be particularly appealing for photographers and collectors. She also applies an isolation coat followed by a top coat of a different sheen to demonstrate how different finishes can be achieved. A matte finish is particularly popular due to its low reflection and aesthetic appeal. The initial layer retains color saturation and vibrancy, while the matte finish enhances the overall look of the artwork.
