Alter chemistry, control flow, and work in unexpected ways with acrylics!
Rewrite how your acrylics behave. Liquitex Additives let you alter chemistry, control flow, and work in unexpected ways. Made without acrylic binders, these four formulas operate outside the rules of traditional mediums. They deliver bold, molecular-level shifts in how your paint moves, dries, and performs. Liquithick brings aerated, sculptural texture. Flow-Aid turns color into a hyper-fluid stream. Each additive creates a distinct, dramatic change in behavior and effect. Experiment freely. Discover how far you can push your paint when you start at the molecular level.
- Increases flow
- Dries transparent or translucent
- Extends the volume of thin paint
- Increases open (working) time

Flow-Aid Additive - Dramatically increase the flow of your color/mediums while minimizing brush strokes. A binder-free aqueous solution with surfactants. Use in conjuction with an acrylic medium or acrylic color when increased flow and absorption and decreased film tension and friction are required.
LiquiThick Additive - Create custom viscosity and a matte finish without increasing paint transparency. A binder-free heavy body gel with high levels of gelling agents. Used in small amounts, it produces handling characteristics very close to that of oil or encaustic paint. At higher concentrations, it can thicken paint or acrylic mediums to "cake" or sculptural consistency.
Slow-Dri Fluid Additive - Slow drying time by 40% without affecting color opacity, so you can work your paint for longer. A binder-free fluid with slow drying agents. Reduces paint skinning-over on the palette.
Slow-Dri Gel Additive - Slow drying time by 40% without affecting color opacity, so you can work your paint for longer. A binder-free gel with slow drying agents. Designed to be used with Liquitex Heavy Body Acrylics and Mediums.
