Winsor & Newton - Water Colour Gum Arabic Medium
Mix with watercolor to boost transparency and create luminous glazes
Enhanced luminosity as pigments suspend more evenly, creating richer glazes that seem to glow from within the paper.
Winsor & Newton formulates this pale solution from natural tree resin, maintaining the purity watercolorists need for predictable results. Mix it directly into paint on your palette to increase transparency for layering techniques, or brush it onto paper as a resist before applying color. Higher concentrations produce glossy surfaces with intensified color depth, particularly effective for jewel-like accents in florals or saturated shadow areas. Dilute with water to adjust the effect from subtle sheen to pronounced gloss.
Professional watercolorists keep gum arabic on hand for technical control it provides: slowing dry time on hot days, improving paint rewetting for corrections, and adding body to diluted washes without sacrificing transparency. The medium integrates seamlessly into any watercolor technique while remaining completely reversible with water.
