The Guerrilla Painter Watercolorboard is high quality precision device designed to tightly stretch 140 lb. to 300 lb. watercolor paper.
As the screws on the frame of the Watercolorboard are tightened, tension is placed on the outside edges of the paper. After the paper has dried, the paper will stay flat and buckle-free during wet washes. A universal tripod mount on backside allows you to attach this setup to a tripod (sold separately). Includes a comfortable carrying handle.
Available in through Cheap Joe's Art Stuff in two convenient sizes.
Half Size - Total Dimensions are just under 17" x 24". Holds a half sheet of watercolor paper (15" x 22"). Weighs 5 lbs.
Full Size - Total Dimensions are just under 24" x 32". Holds a full sheet of watercolor paper (22" x 30"). Weighs 8 lbs.
Watercolorboard Carrying Cases - A high quality nylon carrying case with zipper and a sturdy handle makes it easy to take your Watercolorboard anywhere.
Almost all methods of "stretching" really only attach the paper to the backing board. The paper is not so much "stretched" as "shrunk". When the paper is re-soaked during a wet wash, the small amount of tension that is there is released, and buckles form. I started looking for a simple way to put more tension on the paper. I finally came up with a way to put tension on the paper as it is being tightened down, so that no matter how wet the paper got again, there would always be more tension to keep it flat. The result is The Watercolorboard. ~ Joe Leahy (Inventor of The Watercolorboard)
