Gamblin Oil Painting Ground makes a strong, bright foundation for oil paintings. Formulated from alkyd resin, titanium dioxide, and barium sulfate, Gamblin Ground makes canvas and linen stiffer than acrylic "gesso" and more flexible than traditional oil primers. Barium sulfate gives Gamblin Ground its tooth. Titanium dioxide gives Gamblin Ground its opacity.
This non-absorbent ground works like a traditional oil ground, leaving finished paintings brighter since the oil is left in the paint film instead of being absorbed. Two thin layers of Gamblin Ground equal four layers of acrylic gesso. Instead of linseed oil, Gamblin Ground is made with alkyd resin for increased flexibility and quicker dry time. Traditional linseed oil grounds need about six months to dry. Gamblin Ground is ready for paint application in a few days and may be used directly upon panels without sizing.
