Mix Heavy Body, Fluid, or High Flow Acrylics into Color Pouring Medium Gloss for an almost opaque, glossy and level appearance. Color Pouring Medium Matte provides a low luster finish on color pours. Colors hold their edges when poured wet into wet.Gently mix 10 parts Color Pouring Medium with 1 part acrylic color, 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.
