The Galeria acrylic matt medium from Winsor & Newton delivers even finishes for acrylic colours. Mixed into acrylic paints, this medium maintains the brilliance of colours while creating a flat, even finish when dry. With more medium, the adhesion and durability of paints on the painting surface is improved while transparency is boosted. This acrylic medium is ideal for work where you want to keep texture to a minimum and reduce reflection. - Brand: Winsor & Newton - Range: Galeria - Matt acrylic medium - 500ml
