The Mont Marte Premium Impasto Medium 500ml is a water-based, clear-drying medium expertly formulated to build rich textures and distinct, 3D dimension in acrylic artworks. It can be mixed directly with acrylic paints to enhance body and seamlessly retain crisp brushstrokes or palette knife marks without altering the vibrancy or final color of the pigment. Once completely dry, it forms a durable, stable surface that can easily be painted over with oils, making it an essential extender and texturizer for mixed-media artists.
