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. This is considered a hazardous item and can only be shipped via ground service within the 48 contiguous states.
Gamblin Ground makes a brighter and less-absorbent ground layer compared to acrylic gesso - meaning oil paint layers on top retain better color saturation. Gamblin Ground can be applied to a pre-primed acrylic gesso canvas or panel to make a good painting support a great one.
Because the percentage of pigments is so much higher than in acrylic gesso, you only need to apply two thin coats of Gamblin ground versus the recommended four coats of acrylic gesso. Fabric supports should be sized with PVA Size before applying Gamblin Ground.
