Liquitex, Professional Liquithick Additive 237ml (8oz)

Liquitex professional additives are designed to permanently adjust the chemistry and characteristics of acrylic color. Unlike most mediums—which contain high proportions of acrylic binders—these four additive formulas are made without them, making them distinctly different from the rest of the mediums range. Each additive offers unique effects, from the aerated, sponge-like texture created by Liquithick to the water-like fluidity of Flow-Aid, ideal for watercolor techniques, staining, and flow art. When extended working time is needed without altering color opacity, Slow-Dri Additive—available in both gel and fluid forms—extends open time by up to 40%. These additives allow artists to create custom viscosity and achieve a matte finish without increasing transparency. Liquitex offers a full professional range of acrylic gessoes, mediums, additives, and varnishes—supporting every stage of the creative process, from surface preparation to final protection. Each medium is formulated to produce a specific result, whether that means adding gloss, creating experimental textures, or customizing acrylic paint to suit any artistic practice.
