Fredrix Cradled Canvas Boards provide you with a firm, versatile surface for acrylics, oils and more. A medium textured, acid free and acrylic primed Polycotton canvas is attached to a hardboard core and cradled with sustainably grown pine. A buffered sizing of non-acidic pH protects the canvas fibres from direct contact with the final priming. The canvas has a universal acrylic titanium formula that is suitable for painting in acrylics, oils, water soluble oils, alkyds, spray paints, paint markers & permanent markers.
