Mont Marte Acrylic Colour Paint Signature in Raw Sienna is supplied in a handy 75ml tube for warm natural tones and everyday studio use. The water-based acrylic has a smooth, creamy consistency and good coverage, drying to a semi-matte surface. Its fast-drying character makes it useful for layering, underpainting and building up landscape or still-life colour. Apply to suitable surfaces such as canvas, paper, cardboard and wood. Clean brushes and palettes with water while the paint remains wet.
