Golden Acrylic Flow Release is a concentrate additive for reducing the surface tension of water, thus improving wetting, as well as increasing the flow of acrylic waterborne paints. It can be used to "wet out" pigments and ease their introduction into an acrylic resin, medium or gel. You can also add it to thinner paint mixtures, such as stains, to help reduce surface tension. A wetting agent is very useful for staining techniques, as it dramatically reduces the surface tension between the stain (paint/water) and the support. A medium with endless creative possibilities! Contains 4 oz.
