From [https://www.winsornewton.com/] Choosing complementary oils, solvents, mediums, and varnishes for your oil painting is as unique as choosing a colour palette. Depending on your style and technique, there are a wide range of traditional oils, mediums, and solvents to help you control your colour as well as varnishes to protect your work and provide a final finish. Used to modify the rate of drying, increase gloss, improve flow or add texture, mediums should be used in moderation as an additive to the colour. To complement our oil colour ranges we offer oils, mediums, solvents and varnishes to control, enhance and protect your work. Preparing your surface is an essential first step in your artwork process. PreparePrimers protect your surfaces and provide a controlled absorption for oil painting OilsOils will modify the colours viscosity, gloss and drying time. Using oils maintains the flexibility of paint films, particularly when working fat over lean, preventing over-thinning, when using solvents. MediumsSince binders are already included in the milling process, mediums should be used moderately in conjunction with paint. SolventsSolvents are used to clean brushes and palettes after painting. They should only be used sparingly for thinning colour, so as not to affect the integrity of the paint. Our solvents are made specifically for artists’ use and are fully volatile, meaning they leave no residualmatter when they evaporate from the paint mixture. VarnishesThe final step for finished artwork, to protect it from the build-up of dirt and grease, and the passage of time. Available in a spray or bottle, in matte, satin and gloss finishes. It is important that oil paintings are completely dry before varnishing – this takes six to twelve months, depending on the thickness of the paint.
