Paintings and Canvases on Cementitious Panels
The panel that is being cut at about 1:40
into the video below is similar to something that we came across recently. Some of these panels look like excellent substrates, with a number of advantages over many of the other substrates, including ease of preparation, reasonable cost, durability, stability or resistance to warping, mold and moisture resistance, ease of cutting, and freedom from sagging, among others.
The 1/4" and 1/8" versions are not terribly heavy, and some versions are made to be lighter than the standard versions. These panels can also be used as supports for canvases; and for those who need lighter weight (some plein air painters, for example, or artists who are traveling light), canvas pads or loose sheets of canvas can be used while painting -- and then the finished paintings (or the ones that are worth mounting) can be adhered to the panels afterward.
The 36"x60" panels sell for under ten dollars locally. That's four 18x24s plus two 12x18s (or four 18x24s plus two 12x16s plus two 4x6s), or six 16x20s plus ten 4x6s, or twenty 9x12s, etc., for less than ten dollars:
