Yupo - a slick, smooth, non-absorbent substrate that dramatically changes the way you paint, print or draw. Using this sheet, you can capture nuances, patterns, and shapes that were previously impossible to achieve on conventional watercolor and drawing papers. What makes it even more unique is its lifting quality. You may return to a painting when its done and redo specific areas over and over again. You can build up layers of paint like an oil painter working on a canvas, and then take them off to reveal the white of the sheet. Remember that water activates the paint, even paint put down months ago. Allow YUPO to dry completely. Spray YUPO with a matte-clear finishing spray to seal and protect it. Only use a sealant when your work is complete, as rework and touch-ups become difficult to do after sealing.
