Tru-Color Paint 310 - Acrylic Paint Retarder - 1oz/29.6mL

Paint retarder, also known as drying retarder, is an additive used to slow down the drying time of paint, particularly acrylic paint. It allows artists more time to blend colors, create smooth transitions, and prevent the paint from drying too quickly on the palette or brush. Retarders work by slowing down the evaporation of the paint's liquid components, usually water or a solvent.
