BASICS mediums & Varnishes are developed for students and artists that need dependable quality at an economical price. BASICS mediums are mixed with acrylic paint to adjust how the paint works, feels and looks. They can be used to add texture, adjust paint flow, and alter the working properties of the color. Because they include acrylic resin, these mediums maintain or add to the stability of the paint film, and can be used in any amount desired. BASICS Varnishes are permanent and used to protect finished paintings.
