Our decals are made with Oracal 651 indoor/outdoor vinyl. It will hold up well for 6 years minimum in typical outdoor environments and much longer indoors. The vinyl comes sandwiched between a paper backing and a transfer material, both will be removed upon installation. Our transfer material is RTape 4075, this is a medium tack adhesive and makes for a very easy installation. However, with a medium tack adhesive the transfer material may release from the vinyl before you are ready to install and you will need to reactivate it. Simply heat the face of the material with a heat gun or hair dryer for a few seconds and then swipe it with a hard card.
