Polymer satin Medium & Varnish is a general purpose, flexible mid viscosity medium that serves both as a satin finishing varnish and as a satin additive to the paint. Mixed with acrylic colours, it increases satin and flow characteristics. Used as a finishing varnish, it produces a strong, protective, tack-free, clear film. Promotes flow and levelling. Can be mixed with paint as a medium or used to seal a paint payer before overpainting. Excellent binder and adhesion properties. Dries clear and satin. Permanent and water resistant when dry. Use on flexible surfaces such as canvas.
