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.

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.

13x21 Monet Pro Keyable Braced Frame

• Drawing depicts the exact frame construction, not the proportion
• Precision machined heavy duty keyable tongue-and-groove Stretcher Bars
• A 3/4" thick keyable brace (1.5" wide) provides sturdy support for this 13x21 size frame - Brace may be removed in reinserted at any time
• An exclusive slot is milled on the inside perimeter of the 21 Stretcher Bars to which the Brace and the expansion wedges attach
• Patented keyable brace allows the frame to be tensioned in the middle of the canvas, where the tension needed the most
• 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.

Sustainably Managed Forests Purify the Air

Our forests purify the air by filtering nearly 40% of the fossil fuel emissions humans create, and are critical to reducing global warming. More trees are needed on this planet, not fewer, for our own healthy human survival. Therefore, we use lumber grown in responsibly managed forests, so future generations can benefit from our responsible actions today.

MuseumWrap™ Stretching Technique

Every day that dawns is a gift to me and I take it in that way. I accept it gratefully without looking beyond it. ♦ Henri Matisse

Henri Matisse, a titan of modern art, is best remembered for his vibrant use of color and his ability to express emotions through the simplest of lines and shapes. This zest for life is reflected not just in his artworks, but also in his attitude towards the everyday. Matisse's appreciation for the present moment is beautifully encapsulated in this quote, where he reminds us of the preciousness of each new day.

The world is a perpetual source of inspiration. The play of light at dawn, the quiet introspection of twilight, and the myriad of emotions evoked by changing seasons can serve as potent muses. The gift Matisse speaks of is this ceaseless wonderment with the world around us. By embracing each day with gratitude, we are more attuned to the subtleties that might otherwise escape our notice. Moreover, this mindfulness allows us to delve deeper into our craft, ensuring that our art remains an authentic reflection of our experiences. In a profession that sometimes demands that we constantly think ahead—to the next exhibition, project, or commission—Matisse's perspective is a gentle reminder for us to cherish the present and to find joy in the sheer act of creation.

Creativity is the heart of what we both do. So we've curated this empowering quote and some background. And, in our own act of creation, we provide this unique portrayal we made of Henri Matisse.

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.
