Gamblin Oil Painting Ground makes a strong, bright, non-absorbent foundation for oil paintings. Gamblin Ground is formulated from alkyd resin, titanium dioxide, and calcium carbonate – titanium dioxide gives opacity, while calcium carbonate gives tooth for strong adhesion.
Gamblin Ground makes a brighter and less-absorbent ground layer compared to acrylic “gesso” – meaning that oil paint layers on top will better retain their color saturation. In addition, the lower absorbency allows for “reductive” underpainting techniques when painters need to wipe back to the white of the Ground.
Gamblin Ground can be tinted with any traditional oil color to create a colored ground.
Because the percentage of pigments is so much higher than in acrylic “gesso”, painters need only apply TWO coats of Gamblin Ground instead of the recommended four coats of acrylic. Fabric supports should be sized with PVA Size before applying Gamblin Ground. Also, Gamblin Ground can be applied on top of acrylic gesso for a brighter white, less-absorbent ground layer.
