Watercolor Wash Out Tape - The modern replacement for gummed paper tape. Specially designed for the watercolor artist. This removable tape will withstand very wet paint and will not alter or tear the surface when being removed. This clear plastic, waterproof tape peels off cleanly, and won't ruin the surface or deckle edges of your paper. Wet paper and let dry for 5 minutes, then apply. It adheres best to dry, non-porous boards, such as Incredible Art Board, acrylic sheets, or tempered masonite. It can be used with all watercolor paints, acrylics and even oils.
