LED strips come with gray foam acrylic adhesive backing for easy installation. Strips can be cut every 3 LEDs along the cutting marks with out damage to rest of the LEDs. LED light strips have a waterproof rating of IP65 which provides water resistance so LEDs can be used in an outside setting. They are water resistant, not waterproof, and are NOT suitable to be submerged under water.
