This medium increases the depth, transparency and flow of the colour making it ideal for blending or fine detail work. It can be used in thicker layers than the Glazing Medium and provides an even gloss finish. This medium dries completely clear and maintains no colour shift from wet to dry when used with Winsor & Newton Artists' Acrylic.
I like this medium but I don't use it while I'm painting, but I glaze the finiished work. This way if I notice something that needs improving, I can do it easily and it does not affect the colours, but heightens them. Mary Milborrow (Bexhill-on-sea, United Kingdom) on 17 Feb 2014
