Mediums can be a very important tool when painting, affecting many elements of the performance of a particular paint. A variety of painting styles can benefit from the use of mediums, but perhaps the most common is oil painting. Oil paint mediums are an important part of the oil painting process. While you can work with oils without using a medium, this completely changes the process and many artists find this to be a very difficult way to work.

Depending on the item you use, the right medium can alter drying time to achieve either a slow drying time or a faster one. Mediums can also manipulate consistency and the finish of a painting. We carry a wide range of mediums including oils such as Linseed oil, varnishes, liquin, solvents, pouring mediums and more, from leading brands like Winsor & Newton, Liquitex and Schmincke. Our range will allow you to find the perfect oil painting medium recipe to create just the effect you are looking for with your oils.
