Sennelier Acrylic Gesso is a mixture of acrylic resins and pigments (or colors) that creates an indelible film and enables paint to adhere to canvases and other surfaces.
White Gesso — This universal White Gesso provides a matte surface and exceptional tooth for maximum paint adhesion. It's perfect for painting with both acrylics and oils, on surfaces such as canvas, wood, paper, and board. Use it full strength, or dilute it with water up to 20% to achieve the desired consistency. It may also be tinted by pre-mixing it with Sennelier acrylic colors. As a preparation for acrylic paints, one layer of gesso is sufficient. For oil-based paints, two layers are recommended.
