Why I'm Using Artists Retouching Varnish on my Oil Paintings

Introduction to Artists Retouching Varnish

Artists retouching varnish plays an important role in the preservation and enhancement of oil paintings. This product, specifically formulated by Winsor & Newton, serves multiple purposes that enhance the longevity and look of artworks. Understanding how and why to use this varnish can help your approach to oil painting.

Why Use Artists Retouching Varnish?

My oil paintings can often appear dull or uneven due to the nature of oil paint, which can dry to a matte finish. This retardation of gloss can obscure the vibrant colors of my artwork. When I apply a layer of the retouch varnish it helps to repair any 'sunken-in' areas in the paint film and brings back a consistent, glossy surface to revitalize my painting's colors.

In addition to aesthetic benefits, the use of retouch varnish serves as a barrier against dust, dirt, and possible environmental damage. Oil paintings are prone to yellowing or becoming discolored over time if not properly protected. By adding a layer of retouch varnish it allows my artwork to dry over a longer period while still protecting the painting from dust and dirt

How to Apply Artists Retouching Varnish

I wait for my oil painting to be touch dry before I apply the retouch varnish. Drying time depends on the thickness of your paint and ambient conditions, so could take several weeks. As I paint in fairly thin layers and use a quick drying medium my oil paintings are normally touch dry within a few weeks. Once dry, I prepare the surface by ensuring it is free from dust and grime.

I apply the varnish using a clean, soft brush in a well-ventilated area. It is advisable to use gentle strokes while working in one direction to avoid streaks. For optimal coverage, you may need to apply two thin layers instead of one thick application. Allow the first layer to dry thoroughly before applying the next. This method ensures an even application and enhances the overall gloss of your painting.

Another essential tip is to test the varnish on a scrap piece of canvas or an inconspicuous area of your painting beforehand. This allows you to assess the varnish's impact on color and appearance, ensuring you achieve the desired effect without risking your artwork's integrity.

Retouch varnish can take anywhere from a few hours to a few days to dry. As best practice wait at least 3-4 days before adding any additional coats.

The use of artists retouching varnish from Winsor & Newton can significantly enhance your oil paintings. Not only does it preserve the vivid colors, but it also helps protect your artwork. By understanding how and why to use this varnish, artists can better safeguard their work, ensuring it remains in perfect condition for generations to come.

Advantages of Using Retouch Varnish

Many artists who need a newly completed painting to look ready and freshly varnished for a gallery show or to photograph to send to a client for approval will use retouch varnish as a temporary measure before varnishing, if they do not have time to wait for it to cure before the final layer.

Also, it is possible to paint on top of retouch varnish, to achieve this keep subsequent layers of colour as 'fat' as possible (thinned with lots of medium) and apply them as finely as possible.
