With over 100 years of experience in crafting the finest artist quality canvases, Claessens is recognised worldwide as a leader in the field. Each Claessens canvas undergoes a rigorous treatment and process to meet different requirements for artists.First, all raw canvases are sized with a synthetic PVA glue. For oil primed canvases, the next step involves applying a primer of zinc white paint bound with linseed oil to the glued linen, by means of two knives. The canvas is then put into a drying room for three days where it air-dries naturally.After this first initial drying time, the canvas is then sanded and a coating layer based on titanium white is applied to the canvas by means of two knives and a roller. The canvas is then placed in the drying room for another ten days.Claessens' Oil Primed Canvases are suitable for oil paint.For a full description of the various processes which go into manufacturing a Claessens canvas, click herePlease note: the properties of the weave on this particular canvas means that the priming may have tiny pinholes on its surface, but they don't cause any issues when painting on the canvas.
