Jasart Byron White Gesso acts as a primer by adding tooth to the surface, preparing it for acrylic and oil paint. Simply apply with a coarse brush or palette knife to create a textured surface or use a soft flat brush or roller for a smoother result. The result gives the paint optimal surface to adhere to whilst also offering a balanced absorbency for paint application. Dries to a matt white finish. Suitable for canvas, paper and wood.
