Formulated with the best pigments available, Vallejo Fluid Acrylics are prized for their beauty, stability, and excellent lightfastness. Self-leveling Vallejo Pouring Medium is ideal for techniques of dripping, pouring, and direct application on large surfaces. The acrylic medium dries to a clear, flexible, glossy finish, which is permanent, non-yellowing, and water-resistant when dry. Made with Ampersand's own True Artist Hardbord substrate, Gessobord is perfect for all studio and plein air painting applications. Its fine tooth finish is delicate enough for glazing, fluid brush strokes, and tight detail, yet tough enough to hold up to the most rigorous palette knife painting, collage, and masking techniques.
