Aquacover Liquid Watercolor Paper is designed to match the color and surface of popular brands of watercolor paper. Use Aquacover to make corrections or to add highlights to your watercolor paintings. Aquacover is permanent, non-yellowing, and will not crack. Color can be applied directly over the dried Aquacover, without bleeding. Aquacover performs just like the original watercolor paper surface. In 1oz. bottles with dropper tops. Due to its thick consistency is best applied with a brush rather than the included dropper top.
