Clean worn neoprene with McNett Cotol-240™. For non-textile surfaces roughen and then clean. Apply Aquasure® directly from the tube or with a brush. Leave it overnight to dry (10-14 hours). For the 2-hour process, use McNett Cotol-240 Accelerator. Holes and tears: Create support with duct tape. Fill the gap and the 5mm area around it with Aquasure. Remove the tape when thoroughly dry. Seams: Apply a 2mm thick bead overlapping the seam edges by at least 5mm. Apply slight pressure to fill the surface of the fabric. Note: Avoid skin contact. To remove Aquasure from your hands, rub a piece of cloth with 99% isopropyl alcohol, then wash with soap and water. Caution: Aquasure is slippery when wet. For increased adhesion to footwear, sprinkle with sand ½ hour after application. Storage: Once opened, Aquasure will dry out in the tube if not stored properly. Avoid contact with moisture. Push the contents towards the neck of the tube. Clean off any excess and seal tightly. Store it in a dry place. To extend the shelf life, place the product in a bag in the refrigerator. Leave at room temperature for 6 hours before use. At low temperature unused Aquasure will harden inside the tube. To restore it to its original state or to facilitate its flow, immerse the tube in warm water for 15 minutes or hold it with warm hands until it softens.
