This product is a pure acrylic, high PVC (pigment volume content) canvas primer. It is water based and may be diluted with water or Dala Acrylic Glaze Medium.
Canvas Primer is used to prepare your canvas and make it receptive to paint. It can also protect the canvas against certain paints. Canvas preparation is a personal activity. Some artists choose not to take prepare their surface and prefer to paint straight onto the raw canvas. They enjoy the natural texture of the canvas and treat this inherent texture as a component of the medium, rather than a mere surface. This technique is fine when using acrylic paint, but could be disastrous for oil painters.
Traditionally, canvases where prepared with both a size (glue) and a ground (tooth). Our primer is a modern formulation of the size and the ground. Paint the primer directly onto the canvas and allow it to dry. Paint a second layer at a right angle to the first layer.
This process may be continued, until you have achieved the surface you require. Much like the traditional ground (gesso), this primer can be sanded with a fine-grit sandpaper to a smooth, satin finish. This is an ideal surface for the tempera or water-colour artist.
The linseed oil in oil paint will destroy your canvas if you do not protect against it. Linseed oil is a self-drying oil. Its process of drying is called oxidation - a slow process that may take years to complete. If your canvas is not correctly prepared, the oil will penetrate the fiber, often leaving the pigment on the surface, thereby extending the drying time even further. This moist canvas will rot with time and destroy your painting.
ACRYLIC painters have no problem with the archival properties of canvas. Your binder medium is synthetic and will protect the canvas against rot. You can still prime your surface to prepare it for painting, and most acrylic painters do. Oil painters could also use acrylic to under-paint before applying their oils. This under-painting would serve as a primer and protect the canvas against the linseed oil.
