Self-leveling Vallejo Acrylic Pouring Medium is highly fluid, making it ideal for 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. Its new formulation makes it perfect for creating cells in paint pours without the use of Floetrol. Simply mix Pouring Medium with silicone oil for complex cell effects. Use with Vallejo Acrylic Artist Fluid Colors for best results.
