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.

13x21 Frame Kit B2 Super Heavy Frame Offers the Ultimate Canvas Support!

• Drawing depicts the exact frame construction, not the proportion
• Precision Machined keyable Super Strong Stretcher Bars (1.5" deep by 2-1/4" wide) allow you to increase the canvas tension
• Super Strong Keyable Brace (3/4" x 3.25") and a regular Cross Brace Included
• The Bars have a clever utility groove on the inside perimeter of the frame to attach the cross braces
• Unique Keyable Cross Braces allow you to tension the canvas in the middle, where it's needed the most
• Cross braces are glued and stapled at the 'cross' for maximum support and rigidity
• Both corner keys and brace keys are pre-installed

Elite™ Professional 1.5" Deep B2 Bar • 1/2" Canvas Clearance

A Canvas Clearance of 1/2" 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.

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 we stretch a canvas 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.

Biodiversity in our Forests is the Key to Life as we know it

By using lumber from sustainably managed forests in our products, we can ensure that the forests will continue to thrive and provide valuable resources for years to come. Sustainable forestry practices help to maintain the health and biodiversity of the forest, which benefits not only the environment, but also the local communities and businesses that rely on the forest for their livelihoods.

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 Elite™ 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

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

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.

The new painters do not seek to provide art but to show off how many different things they know. ♦ Albrecht Dürer

A Northern Renaissance master, Albrecht Dürer is celebrated not just for his groundbreaking contributions to printmaking and painting but also for his musings on the nature and purpose of art. Born in Nuremberg, his career was characterized by an insatiable curiosity, evident in his meticulous studies of nature, human anatomy, and geometric principles.

Yet, with this quote, Dürer highlights a concern that feels timeless: the tension between pure artistic expression and the pursuit of novelty or display of skill. Artists have always navigated a fine line between staying true to their vision and adapting to the changing tastes and expectations of their era. In Dürer's time, as in ours, there was a push and pull between tradition and innovation. While it's essential for us to evolve and incorporate new techniques or ideas into our work, Dürer's words serve as a gentle reminder to always prioritize the heart and soul of our creations over mere showmanship or trend-chasing.
