Winsor & Newton mediums and varnishes give artists precise control over paint behaviour, drying time and surface finish. Oil mediums improve flow, transparency and blending, or add body for impasto techniques. Watercolour mediums extend working time, create texture, enhance luminosity or act as resist agents for detailed work. Finishing varnishes in matte and gloss protect completed paintings from dust and UV damage. Whether you are refining a technique or protecting a finished work, these products integrate seamlessly into any oil or watercolour practice. Browse the full Winsor & Newton range.
