This 18inch by 24inch fine woven version of the Winsor & Newton Professional canvas is the perfect surface for oil, acrylic and alkyd colour paintings that include fine detail, for example portraits. The Professional range is designed to meet the needs of the most discerning professional fine artists. These canvases are made of extra smooth, tightly woven, 280gsm archival-quality cotton. The stretcher bars are made from heavy-duty solid pine, which is kiln-dried to provide extra protection against moisture, and has undergone rigorous testing to ensure it will not warp. Each canvas is primed with high-pigment gesso, providing the ideal levels of both tooth and absorbency. Winsor and Newton canvases are expertly pre-stretched by hand, so can be used immediately, but they also come with four Pro Stretcher Devices™ (with patent-pending technology) to enable easier, more precise control over canvas tension than ever before. The canvases are finished with back-stapling and extra cloth tucked behind in the corners which can be used as extra material, should you require it. - Material: Cotton - Canvas Size: 18inch x 14inch - Fabric weight: 280gsm - Depth: 0.82 inches - Quantity: 2 canvases per pack - Backing material: Heavy-duty solid pine - Stretched: Yes, by hand - Primed: Yes, with highly pigmented Gesso - Texture: Very smooth, fine weave - For use with: Oil, acrylic and alkyd colour
