This Galeria acrylic gloss medium from Winsor & Newton offers high clarity and improved flow for acrylic colours. Mixed into acrylic paints, this medium boosts the brilliance of colours while making them more transparent. With more medium, the adhesion and durability of paints on the painting surface is also improved. This acrylic medium is ideal for glazing work and applying thick layers of transparent colour to add depth and create stained-glass effects. - Brand: Winsor & Newton - Range: Galeria - Gloss acrylic medium - 500ml
