You apply stickercals like you would a sticker. You peel off the paper backing off, and apply the decal to your surface. You can cut a piece/corner of the paper backing off to ensure your Stickercal is straight and then peal off the rest of the backing. You can use a squeegee, credit card, or even your finger to ensure it has no bubbles and is laying flat. It is recommended that the decals be applied to a clean, smooth, epoxied surface. Do not sand the area before application as any clear parts of the decal will show the sanding marks.
