Roy Fine Art Canvas Boards are made with a high-quality, acid-free, 100% cotton, medium grain canvas. The canvases have been given three coats of acrylic titanium; triple-priming creates a perfect ready-to-use painting surface for both oils and acrylics. Designed for oil and acrylic painting, these boards can also be used for mixed media, collage, impasto and other heavy textures. The canvas fabric mounted onto board is ideal for plein-air painting as they are lightweight, portable and can be easily stored.
