Step-by-step explanation:
When replacing Velcro tape on the ACES II recovery parachute container before applying the second coat of cement, it is crucial to wait until the first coat of cement is tack free. This typically means waiting until the first coat is no longer sticky to the touch, which could vary based on the type of cement used and environmental conditions such as temperature and humidity.
Before applying a second coat of cement when replacing Velcro tape on the ACES II recovery parachute container, you must wait until the first coat is tack free, which varies based on environmental conditions and the cement's specifications. Allowing the first coat to become tack free ensures a better bond between the layers and helps prevent potential issues such as the Velcro failing to adhere properly. The exact waiting time should be determined according to the manufacturer's recommendations or technical orders.
