Finger Jointed Wood is not meant for Stretcher Bars

Solid wood makes the most dependable Stretcher Bar, because one homogeneous wood member is going to behave similarly across the entire length of the Bar. Whereas, with finger-jointed wood is made-up of multiple pieces of wood, sometimes on the actual joint itself, presenting multiple points of failure which no one can control.

We only use Solid Wood to build our Stretcher Bars because a solid piece of wood will last indefinitely. When we speak of archival value, it's not just the paint you use and the quality of your canvas and ground, even the wood choices manufacturers add or reduce value to your final painting. The fact is, you don't want problems, and finger joints only increase that risk of the wood falling apart in the future.

The glue used to bind finger joints is a water based adhesive and when that wood is exposed to high humidity environments, particularly with exterior walls, the glue joints can give-up. As a manufacturer, Masterpiece® does its part to conserve as much wood as possible, and still provide a quality product that will out-perform any other in the marketplace.

Sustainably Managed Forests

We use lumber grown in the sustainable forests of the Oregon, Washington, and California, where thereÕs more standing timber today than last century! Our forests purify the air, provide oxygen, and reduce global warming. More trees are needed on this planet, not fewer. Therefore, we use lumber grown in responsibly managed forests, so future generations can benefit from our collective responsible actions today.

26x50 is the Canvas Size Needed for this 16x40 Frame

Please note that you will need a canvas that is at least 10 Inches larger than the actual frame size to ensure proper stretching. This will provide ample material to stretch the canvas and attach it to the back of the frame. If you prefer to attach the canvas from the edge of the stretcher frame, you can reduce the size of your canvas by approximately 3/4" all the way around the frame. This will allow you to paint on the edge of the canvas and hang your artwork without needing a separate picture frame. And, if you ever need to remove the canvas from the frame and re-attach it, you'll have enough material to do that too.

Tight'n'Up™ Liquid Canvas Retensioner

One of our most appreciated products helps make your canvas tighter! Stretching a canvas tightly can be a challenge. Our Frame Kits include the Corner and Brace Keys that you will need to add tension, but Tight'n'Up™ Liquid Canvas Re-Tensioner is a way that you can use to add tension to the canvas without needed to use the keys. It canvas be sprayed on the back of a canvas to repair most canvas tension issues.

With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets. Recommended for acrylic primed cotton or linen canvas. We do not recommend it for oil primed canvas because there are simply too many different types of oil primed canvas, but used conservatively at your own risk, it will tension any canvas.

I do want to do the impossible. ♦ Claude Monet

The very essence of Claude Monet, one of the founders of Impressionism, is encapsulated in this sentiment. Monet's radical approach to art defied the traditional conventions of his time. Rather than capturing the world in meticulous detail, he sought to depict the fleeting moments, the interplay of light and its transformative effect on scenes. The result? Canvases that shimmered with life and vitality, evoking emotions more than replicating reality.

In the eyes of many of his contemporaries, what Monet aimed for was nothing short of impossible. But isn't that the nature of art? For artists, the boundaries of what's achievable constantly shift. With every brushstroke, we challenge norms, push limits, and seek to redefine our own capabilities. Like Monet, we might be told that our visions are unrealistic or unattainable, but it's the very act of striving for them that often leads to innovation.

The lesson for us is clear: the 'impossible' is not a rigid barrier but a challenge to be embraced. The beauty of art is not just in the final product but in the audacious pursuit of visions that seem out of reach. By daring to do the impossible, we not only expand the horizons of what art can be but also discover our own untapped potential.
