40x40 Monet Pro Muir Canvas 1-1/2" Deep #MA-4040

True 1:1 Square Proportion - 40x40 Size

40x40 is one of our most desirable square sizes.

The square is perhaps the most intriguing proportion, as it is root of all of the other proportions. It is commonly used in both photography and art. Squares are typically used as the center canvas of a triptych or as a single canvas hung at a 45° angle. The square proportion is long used with medium format professional cameras, and most photographs we see on websites and social media are based on square images. Since all sides of the canvas are the same length, your eye is drawn evenly across the surface of the painting creating a sense of harmony, balance, and a generally a pleasing visual experience. The square format is also a good choice for artists who focus on geometric shapes or patterns in their work, as the regularity of the square shape can help reinforce these elements. Some artists enjoy the challenge of working within the confines of a square format, as it forces them to think creatively resulting in intriguing compositions.

Vegan Ground:

There are no animal products that make-up the sizing and the primer for this fine canvas. Historically, traditional canvas grounds have included egg tempura, pigments with cow urine, and of course, rabbit skin glue. In today's rapidly advancing world, there are many more choices available for artists who prefer non-animal based products that perform far better than their animal-based predecessors.

Muir™ Acrylic Primed Belgian Linen

Characteristic linen type surface texture. It has a bright white tone.

• 100% Belgian Linen 5 oz.; Primed Weight 12 oz. per square yard
• Medium Weight, Open Weave, Textured Surface
• Double Sized and Double Primed with acid-free archival quality acrylic gesso
• Impenetrable ground prevents oil paint from leaching through and harming the canvas
• For acrylics, oils, alkyds, and water miscible oil paints
• Linen has natural oils that prevent disintegration over time.

Titanium Dioxide (TiO₂) Primer Pigment

This primer contains premium-grade Titanium Dioxide (TiO₂) white pigment, renowned for its exceptional performance in acrylic priming. Its standout feature is its enduring whiteness, coupled with remarkable flexibility that persists over time. In contrast to other pigments such as zinc dioxide, Titanium Dioxide maintains its resilience, preventing brittleness as it ages. This quality ensures that artworks retain their integrity and will stand the test of time.

Monet™ Pro 1.5" Deep Bar • 1/2" Canvas Clearance

1/2" Canvas Clearance is the space between the Bar and the canvas. Generally speaking, more clearance reduces the risk of the canvas touching the wood and creating unsightly lines during painting. Our design provides the optimal clearance so as not to impact your painting, but still leaving enough wood to the maximize strength of the Stretcher Bar.

• Produces a 1.5" deep stretched canvas canvas (Actual depth is slightly thinner)
• 1-5/8" wide Stretcher Bar
• Frames with a dimension of 20" and up have a groove machined in the center inside perimeter to which cross braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

No Finger Joints!

Solid Wood is far superior to finger jointed wood, which is many small pieces glued together, each with varying grain densities that absorb and shed moisture at varying rates, expanding and contracting non-uniformly as environmental conditions change, and causing the wood to bow and the finger joints to eventually fail.

A single homogeneous kiln-dried solid wood Stretcher Bar outperforms and outlasts a finger jointed Bar whose sole purpose is to save the manufacturer cost, not contribute to the archival value of artwork intended to last a millennium. 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.

40x40 Monet Pro Frame Kit Extra Heavy Frame Provides Superior Support

• Photo displays the exact frame construction, not the proportion
• Precision machined heavy duty keyable tongue-and-groove Stretcher Bars
• Two super strong 3/4" thick keyable cross braces (3.25" wide) provide the maximum possible support for this 40x40 frame - Cross Braces may be removed and reinserted at any time
• An exclusive slot is milled on the inside perimeter of all of the Stretcher Bars to which the Braces and the expansion wedges attach
• Patented keyable cross braces allow the frame to be tensioned in the middle of the canvas, where the tension needed the most
• Cross braces firmly attached with hardware at the intersection point for maximum support and rigidity
• To increase canvas tension: 1) remove any staples in the corners and those that retain the brace keys in the middle, 2) tap all of the expansion keys further into their respective slots, 3) tighten and re-staple the canvas in the corners

Canvas Tension is in Your Control

In dry climates or air conditioned environments, the lack of moisture in the air causes wood frames to shrink and the canvas fibers to narrow and elongate making the canvas more slack and resulting in a loss of canvas tension. In some instances, the canvas could have waves on the surface resulting in an unsightly viewing experience.

Our Monet™ Pro professional frames provide the functionality for you to slightly expand the size of the frame in the corners and the middle of the canvas, thereby increasing canvas tension all across the surface. The difference between a loose canvas and a tight canvas is just 1/8" of an inch, so a small adjustment using our corner and brace keys makes an important difference in canvas tension.

• Helps to prevent waves that occur in a loose canvas
• Increase canvas tension by tapping-in the corner and brace keys
• True professional class canvases make it possible for you to adjust the canvas tension

Cross Braces Make it Tighter

A tightly stretched canvas on an un-braced frame overpowers the Stretcher Bars causing them to bow inward and thereby lose tension. Sometimes that bow can expose a space in picture frames.

When a canvas is stretched on a properly supported frame, the cross-braces prevent the Bars from bowing thereby achieving maximum canvas tension. To increase the canvas tension even more, simply tap the corner and brace keys further in their slots. Properly supported frames provide you with the control over the canvas tension of your canvas and painting.

Our Ecosystem Depends on Healthy Forests

Forests play a vital role in our planet's ecosystem. They absorb carbon dioxide, filter air and water, and provide habitat for countless species of plants and animals. By using sustainably sourced lumber, we can help to protect these important ecosystems and ensure that they continue to provide these valuable services for generations to come.

Specially Dried and Heat Treated Lumber

We source our wood from a select group of top-tier environmentally conscious lumber mills in the Pacific Northwest. These mills specially dry and heat-treat the lumber to our specifications, resulting in about half the moisture content compared to wood from typical home improvement centers or lumber yards. This process makes the wood stronger, reducing the likelihood of cracking, splitting, or warping. While the wood we use comes at a higher cost, it ensures a more dimensionally stable end product. This stability is crucial for crafting fine professional canvases that support your invaluable art over time.

MuseumWrap™ Stretching Technique

With more than a half a century of American engineering, Masterpiece® designs and builds its own proprietary stretching equipment that enables us to produce the finest and most tightly-stretched canvas on the market.

• Drum-tight stretch!
• Up to 50% tighter than other methods
• Balanced tension across the surface
• Uncut folded corners make it possible to remove and re-stretch canvas on the same size frame
• Usually the corner folds are on the long sides

Oversize Box

This item is classified by UPS and Fedex as oversized, which might incur slightly higher shipping charges. To mitigate the shipping cost, we recommend ordering in quantities of 2 or 4 or more, and it travels safer too.

For over half a century, Masterpiece® has been synonymous with top-tier artist canvases in North America. A canvas isn't just fabric; it's an invitation to create, to turn raw talent into timeless art. Choose wisely, for your art's endurance reflects your legacy and brand distinction.

Art appreciation, like love, cannot be done by proxy. ♦ Robert Henri

A pivotal figure in American art, Robert Henri held a belief that art was a deeply personal experience. His words remind us that true appreciation of any masterpiece requires a firsthand experience. Just as someone cannot delegate the feeling of love to another, an individual cannot genuinely grasp the essence of an artwork without a direct encounter.

As creators, this resonates with our very core. We pour our heart and soul into our pieces, hoping that our viewers will take a moment to immerse themselves, to feel, and to understand our message. When our work speaks to someone, when they connect with it, that moment is irreplaceable. It's a silent dialogue between the creator and the observer, and in that shared moment, the magic of art truly comes alive. It's a reminder for all of us to take the time to truly experience and cherish the art around us, allowing it to touch our hearts directly.

Creativity is everything to us artists, so while you bring canvases to life, we've breathed digital life into a likeness we made of Robert Henri, and provide a quote and context to inspire your art. Together, our creations honor the past, present, and future of artistry. Start spreading some paint around your own canvas!

Tight'n'Up™ Liquid Canvas Retensioner

While all of our Masterpiece® Pro canvases are stretched very tightly and our frames have a built-in method to increase tension, we have another method to add canvas tension. Tight'n'Up™ Liquid Canvas Retensioner (sold separately) can 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.
