Liquitex offers the broadest range of acrylic mediums to inspire creativity at every stage of the painting process. Surface Prep Mediums are used to seal prime and add tooth (for color adhesion) to all surfaces such as canvas wood paper and metal. This same preparation is used for both acrylic and oil paint. Our professional gessoes usually take just one coat, and adding Liquitex Soft Body color to any gesso creates customized tints and primers. Liquitex Clear Gesso Surface Prep Medium is an ideal high tooth for pastel oil pastel graphite and charcoal. Excellent ground for acrylic and oil paint. Mix with acrylic color to have a tinted ground. Dries clear to translucent depending on thickness. Excellent base coat primer for many applications, including murals. Can be applied to any material or surface that will accept traditional acrylic media, such as canvas, paper, wood, etc. Liquitex Surface Prep Mediums are lightweight, non-toxic, and dry to a water-resistant, non-yellowing surface. APPLICATION: For canvas, paper, wood, or any clean porous non-oily surface. Sizes and primes while maintaining the original appearance of the surface. Provides paper with good tooth for chalk and oil pastel techniques. Mix with a very small amount of transparent or translucent acrylic color to tint the ground, while maintaining transparency.
