Fluid acrylic mediums let you adjust how paint spreads, transmits light, and reflects it once dry. Mixed with colour, they can make thin applications easier and increase transparency without relying on excessive dilution with water. They are useful for glazing, a technique that involves applying transparent layers while allowing underlying colours or details to remain visible. Your choice of finish contributes to the result: matte medium reduces reflections, gloss medium adds sheen, and satin offers an intermediate finish. Effects vary with the formula, the amount added, and the opacity of your chosen paint. Follow the manufacturer’s mixing recommendations and let a test sample dry before assessing its appearance. This allows you to compare transparency, flow, and sheen before incorporating the mixture into your composition.
