Fredrix unprimed artist's 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. Their best-selling canvases are universally primed for oil, acrylic or alkyd paints, and they still prime the old fashioned way... picked, pumiced and primed by hand with oil based ground. Available in the 7oz. ARTIST-Series and the 12oz PRO-Series, 100% cotton canvas woven to rigid specifications. Ideal art canvas for artists who need versatility in sizing and the choice to use many different mediums by being able to prime their own canvas exactly as they prefer. 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.
