Mix Heavy Body, Fluid, or High Flow Acrylics into Color Pouring Medium Matte for a low lustre finish on colour pours. Available in sizes: 237ml, 946ml and 3.78 litres. Colours hold their edges when poured wet into wet. Gently mix 10 parts Colour Pouring Medium with 1 part acrylic colour, allow mixture to sit covered (ideally overnight) to eliminate air bubbles. Pour close to the surface to reduce air bubbles. Paintings may need to dry for a few days before moving and tenting is recommended. Do not pour thicker than 1/8” (3mm) or attempt to accelerate drying.
