Tri-Art Opacifying Medium is a professional acrylic medium designed to increase the opacity of transparent and semi-opaque colours without adding white. Hollow acrylic micro-spheres scatter light, providing a dry-hide effect while maintaining the true hue of the colour. Milky and translucent when wet, it dries to an optically opaque, matte finish. Fully compatible with Tri-Art Acrylic Colours, this medium can be mixed in any proportion to create bold, opaque layers without compromising colour integrity.
