Prevent Loose a Canvas with “Canvas Keys”
November 18th, 2007 | by Art Supplies |What are Canvas Keys?
Canvas keys are small pieces of wood that come with a canvas that allow you to stretch and tauten the canvas, while keeping the canvas at the best tension. They are designed so that the artist can paint without fear of the canvas sagging.
They may arrive in a little bag that is stapled to the back of the canvas and may be made of plastic for cheaper canvases. They may even be already applied to the mitred corners of the stretcher bars of your canvas.
There are ready-made slots primed on the canvas which are waiting for you to tap them in to tighten or align the canvas. If the canvas is unprimed or you are stretching the canvas yourself you should only use the keys once the canvas has been primed, to aid in rigidity.
Some canvases have rigid corners and will not require canvas keys, just ensure that before using your canvas that it is taut. Now you will not have to worry about your canvas becoming loose before you can hang your wonderful art piece.
