Liquitex Slow-Dri Fluid Retarder, 4 oz.

Use this acrylic extender medium to slow down drying time, create transparent colors and washes or to improve the paint flow in detail and liner work. It has a fluid consistency that thins all acrylic paint and mediums and increases open time - the time that painters have to blend, spread and work wet-in-wet. It also increases blending time, making blending of colors and detail brushwork easier.
