This Go Diego Go Appliques contain 34 pieces of Peel & Stick Technology will adhere to any smooth surface. Pre-pasted, strippable, and washable, they are truly easy to apply! Begin with a clean, smooth, dry surface (make sure to allow 72 hours for freshly painted surfaces to dry), then immerse each border in lukewarm water for 10 seconds. Position where desired and use a clean, damp sponge to remove bubbles and excess paste. We recommend that you measure well before ordering; it is always best to overestimate your needs.
