Polymer Mediums are used to reduce the viscosity of acrylic paint, extend color, increase translucency, and enhance or reduce gloss. This liquid acrylic medium is viscous, yet pourable, and, when mixed with regular or heavy body acrylics, will thin the paint without reducing the integrity of the paint film. Polymer mediums are excellent for glazing techniques as it promotes flow and diminishes texture. It is also a wonderful adhesive and perfect for collage. And, like other acrylic mediums, it can be mixed with all other acrylic paints and mediums (with the exception of varnishes). Polymer mediums are milky when wet but dry to a clear finish.
