New PRO Series Belgian Linen Pre-Stretched Canvas is considered by many to be the ultimate surface for oil painting and also among the most archival. Our professional-quality, pre-stretched canvases feature the finest, 5.5 oz pure Belgian linen, primed with acid-free acrylic Titanium gesso to a finished weight of 11 oz. Our top of the line stretcher strips are kiln dried to prevent warping with extra bracing for added support ensuring these canvases will stay straight and not warp over time. Fredrix PRO Series Belgian Linen canvases are perfect for oil, acrylic and alkyd paints.
