Not enough pressure when applying the adhesive. Rezztek uses a pressure sensitive adhesive to stick to the blade. After you position it on the blade, make sure to push down hard and roll over with a round object Applying the Rezztek too close to the bottom edge. This can lead to the Rezztek getting in direct contact with the ice. It might cause lower durability of the Rezztek material. Always apply at least 3mm (1/8 of an inch) from the bottom edge of the blade Not allowing the Rezztek to fully adhere to the blade of the hockey stick. Allow the Rezztek to sit on the blade at least 30 minutes before the game. Always apply at room temperature, because the adhesive might not get to full strength when applying on a stick that is ice cold.
