Varnishing oil paintings not only serves as a protective layer but it can also enhance the appearance of the artwork.
Varnishing can shield the painting from dust, dirt, and other contaminants that may damage the surface over time. I find that varnishing gives my artwork a unified sheen, enriching the colors and bringing out the depth of the composition.
When choosing a varnish, I consider two main types: damar and synthetic. Damar is a natural resin that has been traditionally used for centuries. It dries to a glossy finish but can become brittle and yellow over time.
Synthetic varnishes, on the other hand, are made from acrylic and provide a more flexible and UV-resistant finish. They come in various finishes ranging from matte to gloss.
Before varnishing, I ensure that my painting is completely dry. This can take anywhere from 6 months to a year or more, depending on the thickness of the paint layers.
Proper preparation includes removing any surface dirt and loose particles with a soft brush and, if needed, using a mild soap solution to clean heavier dirt.
I then gently rinse and allow the painting to dry completely before applying the varnish.
When varnishing, I carefully brush the varnish evenly across the surface of the painting, working in thin layers. This ensures a consistent finish and allows for better control of the varnish application.
After the varnish has dried completely, it is normal for it to appear slightly darker than before. This effect will dissipate with time, and the painting’s original colors will shine through once more.
In conclusion, varnishing oil paintings is an essential part of preserving and enhancing their beauty.
Choosing the appropriate varnish and applying it carefully, I can extend the life and vibrancy of my artwork for years to come.
