Liquitex - Acrylic Flow Aid

Acrylic Flow Aid

Paint large canvases with smooth, brushstroke-free color transitions

Friction between brush and canvas creates drag that leaves visible marks in your paint film. Flow Aid eliminates that resistance, letting paint glide on smoothly whether you're covering large fields of color or blending transitions that need to stay wet longer. Add just a few drops to acrylics and the paint moves like butter, brush strokes level out, edges soften, and you gain precious working time on non-porous surfaces where acrylics typically grab and dry fast.

The chemistry here changes how paint behaves on different grounds. On canvas or paper, Flow Aid breaks surface tension so paint penetrates fibers like watercolor, creating stain effects and atmospheric washes impossible with straight acrylics. On sealed surfaces like gessoed panels, it increases open time and fluidity without compromising the paint's integrity or adhesion. You control the effect through dilution: more Flow Aid means greater fluidity and longer blending windows.

This works across water-soluble media, acrylics, gouache, inks, dyes, making it useful beyond standard acrylic painting. Airbrush artists use it to prevent tip clogging. Muralists rely on it for seamless coverage across large expanses. Mix it into glazing medium for transitions that flow without fighting you.
