The Daler-Rowney Flow Enhancer is a premium colourless liquid medium engineered to drastically reduce the viscosity of acrylic paints, inks, and dyes. By minimising surface friction, this specialist additive eliminates noticeable brush marks to support flawless glazing, smooth uniform coverage, and crisp hard-edge painting styles. It mixes seamlessly into your palette in small quantities to increase fluid movement and workability without diluting the original color strength or modifying the final finish of your paint.
