The Daler Rowney Simply Acrylic Gesso is an affordable, high-quality white matte primer engineered to seal semi-porous surfaces like canvas, hardboard, and paper for painting. It provides an excellent base with a subtle tooth that enhances pigment adhesion while preventing your oil and acrylic paints from sinking directly into the substrate. Perfect for beginner artists and students, this water-based universal ground can be applied straight from the bottle and sanded down for an ultra-smooth finish.
