Daniel Smith Titanium White Acrylic Gesso is thick and heavily pigmented with excellent coverage. Made with Titanium White pigment, it is opaque, has an excellent lightfast rating and is archival. Daniel Smith Acrylic Gesso is made with a high-grade acrylic emulsion which provides optimal flexibility and durability. It does not contain the oil acids of traditional grounds which tend to deteriorate cotton or linen canvas fibers, so an under sizing, such as rabbit skin glue, is not necessary, and should not be used. Daniel Smith Acrylic Gesso is recommended as a painting ground for acrylics, oils and alkyds, and cleans up with water.
