Artists' quality 8oz cotton canvas rolls consist of carefully selected cotton canvas to ensure outstanding quality. It is ideal for use with oil (including water mixable) acrylic and alkyd colour and can be used for all techniques including heavier application of colour. This range benefits from having a heavy weight superior cloth of medium grain surface that has been triple coated with two coats of highly pigmented primer and one coat of acid free sizing all formulated by Winsor & Newton. Artists' Canvas also offers balanced absorbency and tooth, essential for preventing the sinking of oil colour. This also means that the canvas has improved adhesion.
