All-Media Universally Acrylic Primed Linen Panels. Centurion All-Media Primed Linen Panels are manufactured using the world famous 11oz., universally acrylic primed Centurion Linen Canvas. Acid-free and archival, the primed medium-textured linen is cleanly wrapped and adhered to a solid 3mm MDF wood board. Centurion's beautiful non-mechanical surface is ideal for oils (traditional and water-soluble), acrylics, Caseins, and more brittle media like Egg Tempera and Acrylic Gouache. Perfect for traveling and pochade boxes, the linen panels are lightweight and take up around 1/4 the depth of a 3/4” canvas, so you can travel with more work surfaces! An ideal way to try high quality linen for the first time, at affordable low prices.
