Create outside with Masterpiece Muir Hardcore Pro Canvas Panels. These ready-to-paint, medium-weight Belgian linen canvas panels have engineered-wood rigid-core boards, which are ideal for archival-quality art panels. The 5 oz pre-primed panels are double-sized and double-primed with acrylic for a 12 oz primed weight. They're mounted with a pH-neutral permanent adhesive to durable vinyl backing, which stabilizes the panel to keep it flat and provide an impenetrable moisture barrier. The 1/8" thick panels have a distinct linen surface texture. They're perfect for painting in oils, acrylics, and alkyds.
