Fredrix primed artist canvas rolls. Although the art of manufacturing artist canvas has changed since the 1800s, the product Fredrix makes today is very similar to the canvas made over 140 years ago. The name was changed (Friedrichs to Fredrix), but their mission has not. Made of 100% cotton duck woven to rigid specifications. For making professional, as well as commercial-grade stretched canvas. Fredrix primed canvas rolls are made from selected cotton yarn and coated with acid-free, acrylic titanium primer. Special coating process melds the fabric and primer into one cohesive surface, making a consistent and durable painting surface. These best-selling canvases are universally primed for oil, acrylic or alkyd paints. They still prime the old fashioned way... picked, pumiced and primed by hand with oil based ground.
