Walker Tape’s Ultra Hold gives our most reliable, longest-lasting liquid adhesive hold. It is a maximum wear (4+ weeks) adhesive that is gentle on skin, easy to clean, and dries clear. Ultra Hold provides users with a strong and long-lasting bond. Keep the product away from heat, humidity, and light. Store in a well-ventilated, cool, dark, dry room. Before bonding, prepare skin with 99% Alcohol and Max Hold Sport. Then apply two thin layers of adhesive to the skin or base, and blow dry until very tacky. Next, press the hair system onto the skin and hold firmly for 10 seconds. Do not swim, workout, or shampoo for at least 24 hours. We recommend performing a patch test before use.
