Liquitex Professional Flow-Aid Additive acrylic color and pastelsLiquitex Professional Flow Aid is a concentrated, water based additive that improves the flow, absorption, and blending of acrylic paints, inks, and mediums. Designed to reduce surface tension, it allows color to spread evenly without compromising pigment strength or film integrity. Ideal for techniques such as staining, watercolor effects, and detailed line work, it helps achieve smoother applications on porous surfaces like canvas, paper, and wood.
