Understanding the Importance of Varnish in Oil Painting
The application of varnish is a critical final step in the creation of any oil painting. Not only does it provide a protective layer against dust and damage, but it also enhances the vibrancy of colours and adds a desired finish to the artwork, be it matte, satin, or gloss. Without varnish, oil paintings are susceptible to aging effects, such as yellowing and cracking, significantly reducing their lifespan. The right varnish can also unify the painting's surface, minimizing variations in sheen and making the artwork more visually appealing. The necessity of varnishing an oil painting cannot be overstated, and selecting the right varnish is crucial for any artist.
Types of Varnishes for Oil Paintings
There are primarily two types of varnishes used in oil painting - Damar and synthetic varnishes. Damar varnish, made from Damar resin, has been used by artists for centuries. It dries quickly, giving a moderate gloss to the painting. However, it can yellow over time. Synthetic varnishes, on the other hand, are made from acrylic polymer resins. They are more flexible and resistant to yellowing, but they can take longer to dry. Both types have their pros and cons, and the choice largely depends on the artist's preference and the requirements of the specific artwork.
How to Apply Varnish to an Oil Painting
Applying varnish to an oil painting requires patience and precision. The painting must be completely dry, which can take up to six months for oil paints. The varnish is then diluted with a solvent and applied in thin, even coats using a wide, flat brush. It's essential to work in a well-ventilated area and to allow each layer of varnish to dry before applying the next. The number of coats required depends on the desired level of gloss.
