These Professional Grade Canvas Boards are constructed throughout with the highest quality, non-acidic archival materials. The tempered hardboard core will not warp, become brittle or rot over time. Mounted with a proprietary acid-free adhesive, the painting surface is the same Fredrix medium texture, 100% cotton duck used on Fredrix finest pre-stretched canvas. Grounded with a proprietary, two coat, acid-free formula of acrylic-titanium gesso primer, these Canvas Boards are truly archival.
They are suitable for oils, alkyds, caseins and acrylics. All carry the Fredrix Archival Seal of Quality-your assurance that this product is indeed archival and will stand the test of time. Fredrix nicely finishes their product by folding over the canvas and placing an attractive backing sheet on. Sold in boxes of 12.
