Atelier Unlocking Formula is an essential additive created to work with Atelier Interactive’ s patented formula. When used on an Atelier Interactive painting, artists can reopen a paint layer even after it is touch-dry for blending, edge feathering and more. · Isopropyl alcohol based - evaporates from the surface quickly · Great for mixed media and experimental artists who want to work up and down layers like oil painters · Available in a 250ml bottle · Use to reopen tacky and/or touch-dry layers to facilitate wet-in-wet blending and edge feathering · Use to remove troublesome, uncured paint passages instead of overpainting
