TrueBuy White gesso is a primer and preparatory coating used in art and painting to create a smooth, uniform surface on various substrates such as canvas, wood, paper, or cardboard. It serves as a foundation for acrylic, oil, and other types of paint, enhancing their adhesion and improving the overall quality of the artwork.The primary purpose of white gesso is to create a surface that is ready for painting by filling in surface imperfections, sealing the substrate, and providing a consistent base for the application of paint. It helps to prevent the absorption of paint into the substrate, allowing for better color saturation and reducing the number of paint layers needed to achieve desired results.
