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.

Sierra™ 11.5oz Acrylic Primed Cotton

• 100% Cotton 11.5 oz; Primed Weight 14.6 oz per square yard
• Heavy Weight, Medium Weave, Medium Texture
• Sized and Triple 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

Titanium Dioxide (TiO₂) Primer Pigment

Our primer is made with the highest-quality Titanium Dioxide white pigment, which is an excellent pigment for acrylic primed grounds, providing superior whiteness and maintaining excellent flexibility over time. Unlike some other common pigments, such as zinc dioxide, TiO₂ doesn't become brittle as it ages, helping to ensure that your painting will stand the test of time.

21x34 Vincent Pro Frame Kit Extra Heavy Frame Provides Maximum Support

• Photo displays the exact frame construction, not the proportion
• Precision machined medium duty keyable tongue-and-groove Stretcher Bars
• Two super strong 1/2" thick keyable cross braces (3.25" wide) provide the maximum possible support for this 21x34 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

Vincent™ Pro 7/8" Deep Bar • 5/16" Canvas Clearance

5/16" 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 Stretched Canvas Frame.

• Stretcher Bar Profile produces a 7/8" deep stretched canvas
• 1.5" wide Stretcher Bar
• Frames with a dimension of 16" 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.

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.

Sustainably Managed Forests Inhale and Exhale

The world's forests are essential to human survival. Forests inhale carbon dioxide for the earth, and exhale oxygen essential for life. When we speak of the sustainable forest strategy of ensuring that more timber will exist in the same forest land than exists today, this is the only viable plan for the future of humanity. For this reason, we use only lumber from the sustainable forests of Oregon, Washington, and California, where thereÕs more standing timber today than last century!

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.

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 Vincent™ 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

If you cannot work with love but only with distaste, it is better that you should leave your work. ♦ Kahlil Gibran

Kahlil Gibran's insights, woven with profound wisdom, often addressed the essence of life's pursuits and passions. His belief in the transformative power of love, not just as an emotion but as a driving force, underscores the difference between mere labor and passionate endeavor. When work becomes devoid of love and is pursued only out of obligation, it loses its soul, and the essence of creation is diminished.

In the world of art, passion is the lifeblood. When we engage with our craft, every piece, every creation, is a manifestation of our emotions, desires, and soul. If that engagement is driven by anything other than love, the authenticity wanes, and the connection with the audience is lost. Our work, then, becomes not a celebration of creativity but a mere task. This perspective serves as a guiding light for all of us, emphasizing the need for genuine love and enthusiasm in what we do. Without it, our art might exist, but it will lack the depth, the resonance, and the spirit that makes it truly impactful.

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.
