Acrylic Mediums

Acrylic painting mediums can be added to the paint to either slow or speed the drying time, add a different texture or influence the finish of the paint. Looking for a glossy finish or matt effect? Need more time to work on your painting whilst it's wet? Or maybe you want your brushstrokes to show up clearly on the canvas? Whatever your painting needs, we stock acrylic mediums by leading brands such as Winsor & Newton and Golden that can offer you the solutions. Mix them with the paint on your palette, or dip your brush into them as you would with water, and enjoy the transformation of the paint before your very eyes.
