Fast Drying Meduim is a very popular medium as it speeds the drying of oil colour by about 50%, allowing further layers to be applied more quickly. The formulation has been improved and this has helped to wet the colour better. It thins the colour and increases gloss and transparency. When painting in layers it can substitute linseed oil and be combined with water and/or Thinner to maintain fat over lean.
It certainly dries quick, a bit too quick when thin paint is applied on the underpainting and it causes 'drag', or is it the way I paint? It does the job though, but use it sparingly until you get used to it. David Molloy (Rossendale,, United Kingdom) on 16 Apr 2012

I mostly work with thin layers so this Drying Medium does an excellent job. Each layer dries in just a few hours and the colours are still rich and vibrant. The fact that I can use it with a thinner or water also helps a lot. I 'd rather it didn't increase gloss but I already knew it does before buying so this is not something I'll complain about. No Winsor & Newton product has let me down so far. Ersi Marina Samara Spiliotopulu (Beceite, Spain) on 3 Jan 2018
