Canvas Boards are constructed by means of back-stapling Cotton Duck or Polyester Cloth, or even Belgian linen onto an MDF board base.
The use of canvas boards is a matter of artistic choice – despite the cost advantage, some artists have found preference in using a support structure that has no give under applied brush strokes.
The canvas board is available in 3mm, 6mm and 9mm thicknesses but limited in size to approximately 2440mm x 1220mm. On larger panels, typically over 1.5 meters, it is recommended that a backing frame be laminated to the board for strength requirements. The backing frame also adds depth to the board, given the impression of working on a standard stretcher frame.
The artist can also work on the board directly but due to the glues and other chemicals used in board preparation, it is essential to prepare the surface with a suitable primer.
