The adhesive pad is very strong and will keep the Hydro Holder attached to surface you place it on. However a strong bond will only be achived if the area is clean, dry and the process is done at the recommended temperature and left for the recommended time. (non-porous surfaces only)
Leave for 24-72 hours for the adhesive pad to fully bond. Do this process at room temperature or above (20°C / 68°F).
We recommend not using the Hydro Holder until after 24 hours.
The below graph show bonding time at different temperatures.
