Centurion Deluxe Oil Primed 10"x10" Linen Canvas .67" Deep (Box of 6)Save Up to73%Off listWhite Master Quality Archival Deluxe Stretched Canvas! Superb Performance And Color Retention! Exclusive OP Enhanced Oil Priming! As an oil painter, it is important to work on oil primed surfaces. First, oil on oil will provide the best chemical bond for the paint layers that go on, afterwards. Secondly, gesso are acrylic based, and either repel oil if they have too high of a resin base, or absorb the oil too much if it is too matte, making color sink and look dull and lifeless. Oil priming allows the color to sit cleanly and brightly on the surface, with refraction of the white from below. Centurion’s affordable (OP DLX) oil primed canvas is a great way to start painting with not only an oil primer, but the luxurious texture and archival tradition of linen! Exclusive OP enhanced oil priming! Oil Primed Linen, Deluxe Professional Stretched Canvas (OP DLX) Back stapled to allow for easy re-keying or re-stretching, Centurion Canvases have 4 paintable edges for frameless or floater frame presentation.

Centurion Deluxe Oil Primed 10"x10" Linen Panel, 3 PackSave Up to84%Off listWhite Master Quality Archival Deluxe Linen Panels! Superb performance and color retention! Exclusive OP enhanced oil priming As an oil colorist, it is important to work on oil-primed surfaces and not universally primed surfaces. The reason is that universal primed surfaces are semi-absorbent. Gesso is absorbent even if it is plate smooth. The paint does not get absorbed as much and sits on the surface more making it easy to blend and manipulate. Granted, it is not highly absorbent, but the fact remains that some oil will get into the primer and flatten the image. You can get around this by using an under-painting oil ground on top of the surface of a universal ground canvas, but this is very time-consuming and expensive. Our primer does not contain zinc or lead. The main ingredients used in the coating of these panels are acrylic emulsion, titanium pigment, calcium carbonate, and alkyd resin. Unlike universal ground, our oil priming chemically bonds with the oil paint and is non-absorbent allowing the paint to sit up on the surface with the correct refraction quality of the oil binder. If you use any high-quality oil color, we urge you to use an oil-primed surface, and now we make it affordable! Exclusive OP Enhanced Oil Priming! Centurion Deluxe Professional Oil Primed Linen Panels, specifically designed for oil painters. Superb receptive surface accepts even the thinnest oil color lay down without fragmenting on the surface and is a permanent surface as colors adhere better on it than any other oil primed canvas on the market today! Acid-free and archival, the primed medium-textured linen is cleanly wrapped and adhered to a solid 3mm MDF wood board. Key Features: * Acid-free, Archival Linen Panels * 11oz. Oil Primed * Made of medium weight linen * Exclusive OP enhanced oil priming * Mounted on 3mm (1/8") MDF wood board * Medium weight and texture * Non warping Perfect For: * Artists of all skill levels * Oil and Alkyd Painting * Archival Longevity * Linen Lovers expecting the best! * Professional Artists, Commissioned work * Traveling, takes up 1/4 the space of a 3/4" canvas For a good value on a smooth linen panel, this is it! The fine linen weave makes details easy when painting still life. Our Centurion canvas is used throughout the world by serious artists ranging from dedicated students to the most world-famous artists. Teachers and famous artists asked us to try to come up with an affordable oil-primed linen canvas. Not only did we wow them with quality but we also wowed them with the final price.
